+                    GNU GENERAL PUBLIC LICENSE
+                       Version 3, 29 June 2007
+
+ Copyright (C) 2007 Free Software Foundation, Inc. <https://fsf.org/>
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+                            Preamble
+
+  The GNU General Public License is a free, copyleft license for
+software and other kinds of works.
+
+  The licenses for most software and other practical works are designed
+to take away your freedom to share and change the works.  By contrast,
+the GNU General Public License is intended to guarantee your freedom to
+share and change all versions of a program--to make sure it remains free
+software for all its users.  We, the Free Software Foundation, use the
+GNU General Public License for most of our software; it applies also to
+any other work released this way by its authors.  You can apply it to
+your programs, too.
+
+  When we speak of free software, we are referring to freedom, not
+price.  Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+them if you wish), that you receive source code or can get it if you
+want it, that you can change the software or use pieces of it in new
+free programs, and that you know you can do these things.
+
+  To protect your rights, we need to prevent others from denying you
+these rights or asking you to surrender the rights.  Therefore, you have
+certain responsibilities if you distribute copies of the software, or if
+you modify it: responsibilities to respect the freedom of others.
+
+  For example, if you distribute copies of such a program, whether
+gratis or for a fee, you must pass on to the recipients the same
+freedoms that you received.  You must make sure that they, too, receive
+or can get the source code.  And you must show them these terms so they
+know their rights.
+
+  Developers that use the GNU GPL protect your rights with two steps:
+(1) assert copyright on the software, and (2) offer you this License
+giving you legal permission to copy, distribute and/or modify it.
+
+  For the developers' and authors' protection, the GPL clearly explains
+that there is no warranty for this free software.  For both users' and
+authors' sake, the GPL requires that modified versions be marked as
+changed, so that their problems will not be attributed erroneously to
+authors of previous versions.
+
+  Some devices are designed to deny users access to install or run
+modified versions of the software inside them, although the manufacturer
+can do so.  This is fundamentally incompatible with the aim of
+protecting users' freedom to change the software.  The systematic
+pattern of such abuse occurs in the area of products for individuals to
+use, which is precisely where it is most unacceptable.  Therefore, we
+have designed this version of the GPL to prohibit the practice for those
+products.  If such problems arise substantially in other domains, we
+stand ready to extend this provision to those domains in future versions
+of the GPL, as needed to protect the freedom of users.
+
+  Finally, every program is threatened constantly by software patents.
+States should not allow patents to restrict development and use of
+software on general-purpose computers, but in those that do, we wish to
+avoid the special danger that patents applied to a free program could
+make it effectively proprietary.  To prevent this, the GPL assures that
+patents cannot be used to render the program non-free.
+
+  The precise terms and conditions for copying, distribution and
+modification follow.
+
+                       TERMS AND CONDITIONS
+
+  0. Definitions.
+
+  "This License" refers to version 3 of the GNU General Public License.
+
+  "Copyright" also means copyright-like laws that apply to other kinds of
+works, such as semiconductor masks.
+
+  "The Program" refers to any copyrightable work licensed under this
+License.  Each licensee is addressed as "you".  "Licensees" and
+"recipients" may be individuals or organizations.
+
+  To "modify" a work means to copy from or adapt all or part of the work
+in a fashion requiring copyright permission, other than the making of an
+exact copy.  The resulting work is called a "modified version" of the
+earlier work or a work "based on" the earlier work.
+
+  A "covered work" means either the unmodified Program or a work based
+on the Program.
+
+  To "propagate" a work means to do anything with it that, without
+permission, would make you directly or secondarily liable for
+infringement under applicable copyright law, except executing it on a
+computer or modifying a private copy.  Propagation includes copying,
+distribution (with or without modification), making available to the
+public, and in some countries other activities as well.
+
+  To "convey" a work means any kind of propagation that enables other
+parties to make or receive copies.  Mere interaction with a user through
+a computer network, with no transfer of a copy, is not conveying.
+
+  An interactive user interface displays "Appropriate Legal Notices"
+to the extent that it includes a convenient and prominently visible
+feature that (1) displays an appropriate copyright notice, and (2)
+tells the user that there is no warranty for the work (except to the
+extent that warranties are provided), that licensees may convey the
+work under this License, and how to view a copy of this License.  If
+the interface presents a list of user commands or options, such as a
+menu, a prominent item in the list meets this criterion.
+
+  1. Source Code.
+
+  The "source code" for a work means the preferred form of the work
+for making modifications to it.  "Object code" means any non-source
+form of a work.
+
+  A "Standard Interface" means an interface that either is an official
+standard defined by a recognized standards body, or, in the case of
+interfaces specified for a particular programming language, one that
+is widely used among developers working in that language.
+
+  The "System Libraries" of an executable work include anything, other
+than the work as a whole, that (a) is included in the normal form of
+packaging a Major Component, but which is not part of that Major
+Component, and (b) serves only to enable use of the work with that
+Major Component, or to implement a Standard Interface for which an
+implementation is available to the public in source code form.  A
+"Major Component", in this context, means a major essential component
+(kernel, window system, and so on) of the specific operating system
+(if any) on which the executable work runs, or a compiler used to
+produce the work, or an object code interpreter used to run it.
+
+  The "Corresponding Source" for a work in object code form means all
+the source code needed to generate, install, and (for an executable
+work) run the object code and to modify the work, including scripts to
+control those activities.  However, it does not include the work's
+System Libraries, or general-purpose tools or generally available free
+programs which are used unmodified in performing those activities but
+which are not part of the work.  For example, Corresponding Source
+includes interface definition files associated with source files for
+the work, and the source code for shared libraries and dynamically
+linked subprograms that the work is specifically designed to require,
+such as by intimate data communication or control flow between those
+subprograms and other parts of the work.
+
+  The Corresponding Source need not include anything that users
+can regenerate automatically from other parts of the Corresponding
+Source.
+
+  The Corresponding Source for a work in source code form is that
+same work.
+
+  2. Basic Permissions.
+
+  All rights granted under this License are granted for the term of
+copyright on the Program, and are irrevocable provided the stated
+conditions are met.  This License explicitly affirms your unlimited
+permission to run the unmodified Program.  The output from running a
+covered work is covered by this License only if the output, given its
+content, constitutes a covered work.  This License acknowledges your
+rights of fair use or other equivalent, as provided by copyright law.
+
+  You may make, run and propagate covered works that you do not
+convey, without conditions so long as your license otherwise remains
+in force.  You may convey covered works to others for the sole purpose
+of having them make modifications exclusively for you, or provide you
+with facilities for running those works, provided that you comply with
+the terms of this License in conveying all material for which you do
+not control copyright.  Those thus making or running the covered works
+for you must do so exclusively on your behalf, under your direction
+and control, on terms that prohibit them from making any copies of
+your copyrighted material outside their relationship with you.
+
+  Conveying under any other circumstances is permitted solely under
+the conditions stated below.  Sublicensing is not allowed; section 10
+makes it unnecessary.
+
+  3. Protecting Users' Legal Rights From Anti-Circumvention Law.
+
+  No covered work shall be deemed part of an effective technological
+measure under any applicable law fulfilling obligations under article
+11 of the WIPO copyright treaty adopted on 20 December 1996, or
+similar laws prohibiting or restricting circumvention of such
+measures.
+
+  When you convey a covered work, you waive any legal power to forbid
+circumvention of technological measures to the extent such circumvention
+is effected by exercising rights under this License with respect to
+the covered work, and you disclaim any intention to limit operation or
+modification of the work as a means of enforcing, against the work's
+users, your or third parties' legal rights to forbid circumvention of
+technological measures.
+
+  4. Conveying Verbatim Copies.
+
+  You may convey verbatim copies of the Program's source code as you
+receive it, in any medium, provided that you conspicuously and
+appropriately publish on each copy an appropriate copyright notice;
+keep intact all notices stating that this License and any
+non-permissive terms added in accord with section 7 apply to the code;
+keep intact all notices of the absence of any warranty; and give all
+recipients a copy of this License along with the Program.
+
+  You may charge any price or no price for each copy that you convey,
+and you may offer support or warranty protection for a fee.
+
+  5. Conveying Modified Source Versions.
+
+  You may convey a work based on the Program, or the modifications to
+produce it from the Program, in the form of source code under the
+terms of section 4, provided that you also meet all of these conditions:
+
+    a) The work must carry prominent notices stating that you modified
+    it, and giving a relevant date.
+
+    b) The work must carry prominent notices stating that it is
+    released under this License and any conditions added under section
+    7.  This requirement modifies the requirement in section 4 to
+    "keep intact all notices".
+
+    c) You must license the entire work, as a whole, under this
+    License to anyone who comes into possession of a copy.  This
+    License will therefore apply, along with any applicable section 7
+    additional terms, to the whole of the work, and all its parts,
+    regardless of how they are packaged.  This License gives no
+    permission to license the work in any other way, but it does not
+    invalidate such permission if you have separately received it.
+
+    d) If the work has interactive user interfaces, each must display
+    Appropriate Legal Notices; however, if the Program has interactive
+    interfaces that do not display Appropriate Legal Notices, your
+    work need not make them do so.
+
+  A compilation of a covered work with other separate and independent
+works, which are not by their nature extensions of the covered work,
+and which are not combined with it such as to form a larger program,
+in or on a volume of a storage or distribution medium, is called an
+"aggregate" if the compilation and its resulting copyright are not
+used to limit the access or legal rights of the compilation's users
+beyond what the individual works permit.  Inclusion of a covered work
+in an aggregate does not cause this License to apply to the other
+parts of the aggregate.
+
+  6. Conveying Non-Source Forms.
+
+  You may convey a covered work in object code form under the terms
+of sections 4 and 5, provided that you also convey the
+machine-readable Corresponding Source under the terms of this License,
+in one of these ways:
+
+    a) Convey the object code in, or embodied in, a physical product
+    (including a physical distribution medium), accompanied by the
+    Corresponding Source fixed on a durable physical medium
+    customarily used for software interchange.
+
+    b) Convey the object code in, or embodied in, a physical product
+    (including a physical distribution medium), accompanied by a
+    written offer, valid for at least three years and valid for as
+    long as you offer spare parts or customer support for that product
+    model, to give anyone who possesses the object code either (1) a
+    copy of the Corresponding Source for all the software in the
+    product that is covered by this License, on a durable physical
+    medium customarily used for software interchange, for a price no
+    more than your reasonable cost of physically performing this
+    conveying of source, or (2) access to copy the
+    Corresponding Source from a network server at no charge.
+
+    c) Convey individual copies of the object code with a copy of the
+    written offer to provide the Corresponding Source.  This
+    alternative is allowed only occasionally and noncommercially, and
+    only if you received the object code with such an offer, in accord
+    with subsection 6b.
+
+    d) Convey the object code by offering access from a designated
+    place (gratis or for a charge), and offer equivalent access to the
+    Corresponding Source in the same way through the same place at no
+    further charge.  You need not require recipients to copy the
+    Corresponding Source along with the object code.  If the place to
+    copy the object code is a network server, the Corresponding Source
+    may be on a different server (operated by you or a third party)
+    that supports equivalent copying facilities, provided you maintain
+    clear directions next to the object code saying where to find the
+    Corresponding Source.  Regardless of what server hosts the
+    Corresponding Source, you remain obligated to ensure that it is
+    available for as long as needed to satisfy these requirements.
+
+    e) Convey the object code using peer-to-peer transmission, provided
+    you inform other peers where the object code and Corresponding
+    Source of the work are being offered to the general public at no
+    charge under subsection 6d.
+
+  A separable portion of the object code, whose source code is excluded
+from the Corresponding Source as a System Library, need not be
+included in conveying the object code work.
+
+  A "User Product" is either (1) a "consumer product", which means any
+tangible personal property which is normally used for personal, family,
+or household purposes, or (2) anything designed or sold for incorporation
+into a dwelling.  In determining whether a product is a consumer product,
+doubtful cases shall be resolved in favor of coverage.  For a particular
+product received by a particular user, "normally used" refers to a
+typical or common use of that class of product, regardless of the status
+of the particular user or of the way in which the particular user
+actually uses, or expects or is expected to use, the product.  A product
+is a consumer product regardless of whether the product has substantial
+commercial, industrial or non-consumer uses, unless such uses represent
+the only significant mode of use of the product.
+
+  "Installation Information" for a User Product means any methods,
+procedures, authorization keys, or other information required to install
+and execute modified versions of a covered work in that User Product from
+a modified version of its Corresponding Source.  The information must
+suffice to ensure that the continued functioning of the modified object
+code is in no case prevented or interfered with solely because
+modification has been made.
+
+  If you convey an object code work under this section in, or with, or
+specifically for use in, a User Product, and the conveying occurs as
+part of a transaction in which the right of possession and use of the
+User Product is transferred to the recipient in perpetuity or for a
+fixed term (regardless of how the transaction is characterized), the
+Corresponding Source conveyed under this section must be accompanied
+by the Installation Information.  But this requirement does not apply
+if neither you nor any third party retains the ability to install
+modified object code on the User Product (for example, the work has
+been installed in ROM).
+
+  The requirement to provide Installation Information does not include a
+requirement to continue to provide support service, warranty, or updates
+for a work that has been modified or installed by the recipient, or for
+the User Product in which it has been modified or installed.  Access to a
+network may be denied when the modification itself materially and
+adversely affects the operation of the network or violates the rules and
+protocols for communication across the network.
+
+  Corresponding Source conveyed, and Installation Information provided,
+in accord with this section must be in a format that is publicly
+documented (and with an implementation available to the public in
+source code form), and must require no special password or key for
+unpacking, reading or copying.
+
+  7. Additional Terms.
+
+  "Additional permissions" are terms that supplement the terms of this
+License by making exceptions from one or more of its conditions.
+Additional permissions that are applicable to the entire Program shall
+be treated as though they were included in this License, to the extent
+that they are valid under applicable law.  If additional permissions
+apply only to part of the Program, that part may be used separately
+under those permissions, but the entire Program remains governed by
+this License without regard to the additional permissions.
+
+  When you convey a copy of a covered work, you may at your option
+remove any additional permissions from that copy, or from any part of
+it.  (Additional permissions may be written to require their own
+removal in certain cases when you modify the work.)  You may place
+additional permissions on material, added by you to a covered work,
+for which you have or can give appropriate copyright permission.
+
+  Notwithstanding any other provision of this License, for material you
+add to a covered work, you may (if authorized by the copyright holders of
+that material) supplement the terms of this License with terms:
+
+    a) Disclaiming warranty or limiting liability differently from the
+    terms of sections 15 and 16 of this License; or
+
+    b) Requiring preservation of specified reasonable legal notices or
+    author attributions in that material or in the Appropriate Legal
+    Notices displayed by works containing it; or
+
+    c) Prohibiting misrepresentation of the origin of that material, or
+    requiring that modified versions of such material be marked in
+    reasonable ways as different from the original version; or
+
+    d) Limiting the use for publicity purposes of names of licensors or
+    authors of the material; or
+
+    e) Declining to grant rights under trademark law for use of some
+    trade names, trademarks, or service marks; or
+
+    f) Requiring indemnification of licensors and authors of that
+    material by anyone who conveys the material (or modified versions of
+    it) with contractual assumptions of liability to the recipient, for
+    any liability that these contractual assumptions directly impose on
+    those licensors and authors.
+
+  All other non-permissive additional terms are considered "further
+restrictions" within the meaning of section 10.  If the Program as you
+received it, or any part of it, contains a notice stating that it is
+governed by this License along with a term that is a further
+restriction, you may remove that term.  If a license document contains
+a further restriction but permits relicensing or conveying under this
+License, you may add to a covered work material governed by the terms
+of that license document, provided that the further restriction does
+not survive such relicensing or conveying.
+
+  If you add terms to a covered work in accord with this section, you
+must place, in the relevant source files, a statement of the
+additional terms that apply to those files, or a notice indicating
+where to find the applicable terms.
+
+  Additional terms, permissive or non-permissive, may be stated in the
+form of a separately written license, or stated as exceptions;
+the above requirements apply either way.
+
+  8. Termination.
+
+  You may not propagate or modify a covered work except as expressly
+provided under this License.  Any attempt otherwise to propagate or
+modify it is void, and will automatically terminate your rights under
+this License (including any patent licenses granted under the third
+paragraph of section 11).
+
+  However, if you cease all violation of this License, then your
+license from a particular copyright holder is reinstated (a)
+provisionally, unless and until the copyright holder explicitly and
+finally terminates your license, and (b) permanently, if the copyright
+holder fails to notify you of the violation by some reasonable means
+prior to 60 days after the cessation.
+
+  Moreover, your license from a particular copyright holder is
+reinstated permanently if the copyright holder notifies you of the
+violation by some reasonable means, this is the first time you have
+received notice of violation of this License (for any work) from that
+copyright holder, and you cure the violation prior to 30 days after
+your receipt of the notice.
+
+  Termination of your rights under this section does not terminate the
+licenses of parties who have received copies or rights from you under
+this License.  If your rights have been terminated and not permanently
+reinstated, you do not qualify to receive new licenses for the same
+material under section 10.
+
+  9. Acceptance Not Required for Having Copies.
+
+  You are not required to accept this License in order to receive or
+run a copy of the Program.  Ancillary propagation of a covered work
+occurring solely as a consequence of using peer-to-peer transmission
+to receive a copy likewise does not require acceptance.  However,
+nothing other than this License grants you permission to propagate or
+modify any covered work.  These actions infringe copyright if you do
+not accept this License.  Therefore, by modifying or propagating a
+covered work, you indicate your acceptance of this License to do so.
+
+  10. Automatic Licensing of Downstream Recipients.
+
+  Each time you convey a covered work, the recipient automatically
+receives a license from the original licensors, to run, modify and
+propagate that work, subject to this License.  You are not responsible
+for enforcing compliance by third parties with this License.
+
+  An "entity transaction" is a transaction transferring control of an
+organization, or substantially all assets of one, or subdividing an
+organization, or merging organizations.  If propagation of a covered
+work results from an entity transaction, each party to that
+transaction who receives a copy of the work also receives whatever
+licenses to the work the party's predecessor in interest had or could
+give under the previous paragraph, plus a right to possession of the
+Corresponding Source of the work from the predecessor in interest, if
+the predecessor has it or can get it with reasonable efforts.
+
+  You may not impose any further restrictions on the exercise of the
+rights granted or affirmed under this License.  For example, you may
+not impose a license fee, royalty, or other charge for exercise of
+rights granted under this License, and you may not initiate litigation
+(including a cross-claim or counterclaim in a lawsuit) alleging that
+any patent claim is infringed by making, using, selling, offering for
+sale, or importing the Program or any portion of it.
+
+  11. Patents.
+
+  A "contributor" is a copyright holder who authorizes use under this
+License of the Program or a work on which the Program is based.  The
+work thus licensed is called the contributor's "contributor version".
+
+  A contributor's "essential patent claims" are all patent claims
+owned or controlled by the contributor, whether already acquired or
+hereafter acquired, that would be infringed by some manner, permitted
+by this License, of making, using, or selling its contributor version,
+but do not include claims that would be infringed only as a
+consequence of further modification of the contributor version.  For
+purposes of this definition, "control" includes the right to grant
+patent sublicenses in a manner consistent with the requirements of
+this License.
+
+  Each contributor grants you a non-exclusive, worldwide, royalty-free
+patent license under the contributor's essential patent claims, to
+make, use, sell, offer for sale, import and otherwise run, modify and
+propagate the contents of its contributor version.
+
+  In the following three paragraphs, a "patent license" is any express
+agreement or commitment, however denominated, not to enforce a patent
+(such as an express permission to practice a patent or covenant not to
+sue for patent infringement).  To "grant" such a patent license to a
+party means to make such an agreement or commitment not to enforce a
+patent against the party.
+
+  If you convey a covered work, knowingly relying on a patent license,
+and the Corresponding Source of the work is not available for anyone
+to copy, free of charge and under the terms of this License, through a
+publicly available network server or other readily accessible means,
+then you must either (1) cause the Corresponding Source to be so
+available, or (2) arrange to deprive yourself of the benefit of the
+patent license for this particular work, or (3) arrange, in a manner
+consistent with the requirements of this License, to extend the patent
+license to downstream recipients.  "Knowingly relying" means you have
+actual knowledge that, but for the patent license, your conveying the
+covered work in a country, or your recipient's use of the covered work
+in a country, would infringe one or more identifiable patents in that
+country that you have reason to believe are valid.
+
+  If, pursuant to or in connection with a single transaction or
+arrangement, you convey, or propagate by procuring conveyance of, a
+covered work, and grant a patent license to some of the parties
+receiving the covered work authorizing them to use, propagate, modify
+or convey a specific copy of the covered work, then the patent license
+you grant is automatically extended to all recipients of the covered
+work and works based on it.
+
+  A patent license is "discriminatory" if it does not include within
+the scope of its coverage, prohibits the exercise of, or is
+conditioned on the non-exercise of one or more of the rights that are
+specifically granted under this License.  You may not convey a covered
+work if you are a party to an arrangement with a third party that is
+in the business of distributing software, under which you make payment
+to the third party based on the extent of your activity of conveying
+the work, and under which the third party grants, to any of the
+parties who would receive the covered work from you, a discriminatory
+patent license (a) in connection with copies of the covered work
+conveyed by you (or copies made from those copies), or (b) primarily
+for and in connection with specific products or compilations that
+contain the covered work, unless you entered into that arrangement,
+or that patent license was granted, prior to 28 March 2007.
+
+  Nothing in this License shall be construed as excluding or limiting
+any implied license or other defenses to infringement that may
+otherwise be available to you under applicable patent law.
+
+  12. No Surrender of Others' Freedom.
+
+  If conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License.  If you cannot convey a
+covered work so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you may
+not convey it at all.  For example, if you agree to terms that obligate you
+to collect a royalty for further conveying from those to whom you convey
+the Program, the only way you could satisfy both those terms and this
+License would be to refrain entirely from conveying the Program.
+
+  13. Use with the GNU Affero General Public License.
+
+  Notwithstanding any other provision of this License, you have
+permission to link or combine any covered work with a work licensed
+under version 3 of the GNU Affero General Public License into a single
+combined work, and to convey the resulting work.  The terms of this
+License will continue to apply to the part which is the covered work,
+but the special requirements of the GNU Affero General Public License,
+section 13, concerning interaction through a network will apply to the
+combination as such.
+
+  14. Revised Versions of this License.
+
+  The Free Software Foundation may publish revised and/or new versions of
+the GNU General Public License from time to time.  Such new versions will
+be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.
+
+  Each version is given a distinguishing version number.  If the
+Program specifies that a certain numbered version of the GNU General
+Public License "or any later version" applies to it, you have the
+option of following the terms and conditions either of that numbered
+version or of any later version published by the Free Software
+Foundation.  If the Program does not specify a version number of the
+GNU General Public License, you may choose any version ever published
+by the Free Software Foundation.
+
+  If the Program specifies that a proxy can decide which future
+versions of the GNU General Public License can be used, that proxy's
+public statement of acceptance of a version permanently authorizes you
+to choose that version for the Program.
+
+  Later license versions may give you additional or different
+permissions.  However, no additional obligations are imposed on any
+author or copyright holder as a result of your choosing to follow a
+later version.
+
+  15. Disclaimer of Warranty.
+
+  THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
+APPLICABLE LAW.  EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
+HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY
+OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
+THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
+PURPOSE.  THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM
+IS WITH YOU.  SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
+ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
+
+  16. Limitation of Liability.
+
+  IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
+THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
+GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE
+USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF
+DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
+PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),
+EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF
+SUCH DAMAGES.
+
+  17. Interpretation of Sections 15 and 16.
+
+  If the disclaimer of warranty and limitation of liability provided
+above cannot be given local legal effect according to their terms,
+reviewing courts shall apply local law that most closely approximates
+an absolute waiver of all civil liability in connection with the
+Program, unless a warranty or assumption of liability accompanies a
+copy of the Program in return for a fee.
+
+                     END OF TERMS AND CONDITIONS

+                       Version 3, 29 June 2007
+
+ Copyright (C) 2007 Free Software Foundation, Inc. <https://fsf.org/>
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+
+  This version of the GNU Lesser General Public License incorporates
+the terms and conditions of version 3 of the GNU General Public
+License, supplemented by the additional permissions listed below.
+
+  0. Additional Definitions.
+
+  As used herein, "this License" refers to version 3 of the GNU Lesser
+General Public License, and the "GNU GPL" refers to version 3 of the GNU
+General Public License.
+
+  "The Library" refers to a covered work governed by this License,
+other than an Application or a Combined Work as defined below.
+
+  An "Application" is any work that makes use of an interface provided
+by the Library, but which is not otherwise based on the Library.
+Defining a subclass of a class defined by the Library is deemed a mode
+of using an interface provided by the Library.
+
+  A "Combined Work" is a work produced by combining or linking an
+Application with the Library.  The particular version of the Library
+with which the Combined Work was made is also called the "Linked
+Version".
+
+  The "Minimal Corresponding Source" for a Combined Work means the
+Corresponding Source for the Combined Work, excluding any source code
+for portions of the Combined Work that, considered in isolation, are
+based on the Application, and not on the Linked Version.
+
+  The "Corresponding Application Code" for a Combined Work means the
+object code and/or source code for the Application, including any data
+and utility programs needed for reproducing the Combined Work from the
+Application, but excluding the System Libraries of the Combined Work.
+
+  1. Exception to Section 3 of the GNU GPL.
+
+  You may convey a covered work under sections 3 and 4 of this License
+without being bound by section 3 of the GNU GPL.
+
+  2. Conveying Modified Versions.
+
+  If you modify a copy of the Library, and, in your modifications, a
+facility refers to a function or data to be supplied by an Application
+that uses the facility (other than as an argument passed when the
+facility is invoked), then you may convey a copy of the modified
+version:
+
+   a) under this License, provided that you make a good faith effort to
+   ensure that, in the event an Application does not supply the
+   function or data, the facility still operates, and performs
+   whatever part of its purpose remains meaningful, or
+
+   b) under the GNU GPL, with none of the additional permissions of
+   this License applicable to that copy.
+
+  3. Object Code Incorporating Material from Library Header Files.
+
+  The object code form of an Application may incorporate material from
+a header file that is part of the Library.  You may convey such object
+code under terms of your choice, provided that, if the incorporated
+material is not limited to numerical parameters, data structure
+layouts and accessors, or small macros, inline functions and templates
+(ten or fewer lines in length), you do both of the following:
+
+   a) Give prominent notice with each copy of the object code that the
+   Library is used in it and that the Library and its use are
+   covered by this License.
+
+   b) Accompany the object code with a copy of the GNU GPL and this license
+   document.
+
+  4. Combined Works.
+
+  You may convey a Combined Work under terms of your choice that,
+taken together, effectively do not restrict modification of the
+portions of the Library contained in the Combined Work and reverse
+engineering for debugging such modifications, if you also do each of
+the following:
+
+   a) Give prominent notice with each copy of the Combined Work that
+   the Library is used in it and that the Library and its use are
+   covered by this License.
+
+   b) Accompany the Combined Work with a copy of the GNU GPL and this license
+   document.
+
+   c) For a Combined Work that displays copyright notices during
+   execution, include the copyright notice for the Library among
+   these notices, as well as a reference directing the user to the
+   copies of the GNU GPL and this license document.
+
+   d) Do one of the following:
+
+       0) Convey the Minimal Corresponding Source under the terms of this
+       License, and the Corresponding Application Code in a form
+       suitable for, and under terms that permit, the user to
+       recombine or relink the Application with a modified version of
+       the Linked Version to produce a modified Combined Work, in the
+       manner specified by section 6 of the GNU GPL for conveying
+       Corresponding Source.
+
+       1) Use a suitable shared library mechanism for linking with the
+       Library.  A suitable mechanism is one that (a) uses at run time
+       a copy of the Library already present on the user's computer
+       system, and (b) will operate properly with a modified version
+       of the Library that is interface-compatible with the Linked
+       Version.
+
+   e) Provide Installation Information, but only if you would otherwise
+   be required to provide such information under section 6 of the
+   GNU GPL, and only to the extent that such information is
+   necessary to install and execute a modified version of the
+   Combined Work produced by recombining or relinking the
+   Application with a modified version of the Linked Version. (If
+   you use option 4d0, the Installation Information must accompany
+   the Minimal Corresponding Source and Corresponding Application
+   Code. If you use option 4d1, you must provide the Installation
+   Information in the manner specified by section 6 of the GNU GPL
+   for conveying Corresponding Source.)
+
+  5. Combined Libraries.
+
+  You may place library facilities that are a work based on the
+Library side by side in a single library together with other library
+facilities that are not Applications and are not covered by this
+License, and convey such a combined library under terms of your
+choice, if you do both of the following:
+
+   a) Accompany the combined library with a copy of the same work based
+   on the Library, uncombined with any other library facilities,
+   conveyed under the terms of this License.
+
+   b) Give prominent notice with the combined library that part of it
+   is a work based on the Library, and explaining where to find the
+   accompanying uncombined form of the same work.
+
+  6. Revised Versions of the GNU Lesser General Public License.
+
+  The Free Software Foundation may publish revised and/or new versions
+of the GNU Lesser General Public License from time to time. Such new
+versions will be similar in spirit to the present version, but may
+differ in detail to address new problems or concerns.
+
+  Each version is given a distinguishing version number. If the
+Library as you received it specifies that a certain numbered version
+of the GNU Lesser General Public License "or any later version"
+applies to it, you have the option of following the terms and
+conditions either of that published version or of any later version
+published by the Free Software Foundation. If the Library as you
+received it does not specify a version number of the GNU Lesser
+General Public License, you may choose any version of the GNU Lesser
+General Public License ever published by the Free Software Foundation.
+
+  If the Library as you received it specifies that a proxy can decide
+whether future versions of the GNU Lesser General Public License shall
+apply, that proxy's public statement of acceptance of any version is
+permanent authorization for you to choose that version for the
+Library.

+                    GNU GENERAL PUBLIC LICENSE
+                       Version 3, 29 June 2007
+
+ Copyright (C) 2007 Free Software Foundation, Inc. <https://fsf.org/>
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+                            Preamble
+
+  The GNU General Public License is a free, copyleft license for
+software and other kinds of works.
+
+  The licenses for most software and other practical works are designed
+to take away your freedom to share and change the works.  By contrast,
+the GNU General Public License is intended to guarantee your freedom to
+share and change all versions of a program--to make sure it remains free
+software for all its users.  We, the Free Software Foundation, use the
+GNU General Public License for most of our software; it applies also to
+any other work released this way by its authors.  You can apply it to
+your programs, too.
+
+  When we speak of free software, we are referring to freedom, not
+price.  Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+them if you wish), that you receive source code or can get it if you
+want it, that you can change the software or use pieces of it in new
+free programs, and that you know you can do these things.
+
+  To protect your rights, we need to prevent others from denying you
+these rights or asking you to surrender the rights.  Therefore, you have
+certain responsibilities if you distribute copies of the software, or if
+you modify it: responsibilities to respect the freedom of others.
+
+  For example, if you distribute copies of such a program, whether
+gratis or for a fee, you must pass on to the recipients the same
+freedoms that you received.  You must make sure that they, too, receive
+or can get the source code.  And you must show them these terms so they
+know their rights.
+
+  Developers that use the GNU GPL protect your rights with two steps:
+(1) assert copyright on the software, and (2) offer you this License
+giving you legal permission to copy, distribute and/or modify it.
+
+  For the developers' and authors' protection, the GPL clearly explains
+that there is no warranty for this free software.  For both users' and
+authors' sake, the GPL requires that modified versions be marked as
+changed, so that their problems will not be attributed erroneously to
+authors of previous versions.
+
+  Some devices are designed to deny users access to install or run
+modified versions of the software inside them, although the manufacturer
+can do so.  This is fundamentally incompatible with the aim of
+protecting users' freedom to change the software.  The systematic
+pattern of such abuse occurs in the area of products for individuals to
+use, which is precisely where it is most unacceptable.  Therefore, we
+have designed this version of the GPL to prohibit the practice for those
+products.  If such problems arise substantially in other domains, we
+stand ready to extend this provision to those domains in future versions
+of the GPL, as needed to protect the freedom of users.
+
+  Finally, every program is threatened constantly by software patents.
+States should not allow patents to restrict development and use of
+software on general-purpose computers, but in those that do, we wish to
+avoid the special danger that patents applied to a free program could
+make it effectively proprietary.  To prevent this, the GPL assures that
+patents cannot be used to render the program non-free.
+
+  The precise terms and conditions for copying, distribution and
+modification follow.
+
+                       TERMS AND CONDITIONS
+
+  0. Definitions.
+
+  "This License" refers to version 3 of the GNU General Public License.
+
+  "Copyright" also means copyright-like laws that apply to other kinds of
+works, such as semiconductor masks.
+
+  "The Program" refers to any copyrightable work licensed under this
+License.  Each licensee is addressed as "you".  "Licensees" and
+"recipients" may be individuals or organizations.
+
+  To "modify" a work means to copy from or adapt all or part of the work
+in a fashion requiring copyright permission, other than the making of an
+exact copy.  The resulting work is called a "modified version" of the
+earlier work or a work "based on" the earlier work.
+
+  A "covered work" means either the unmodified Program or a work based
+on the Program.
+
+  To "propagate" a work means to do anything with it that, without
+permission, would make you directly or secondarily liable for
+infringement under applicable copyright law, except executing it on a
+computer or modifying a private copy.  Propagation includes copying,
+distribution (with or without modification), making available to the
+public, and in some countries other activities as well.
+
+  To "convey" a work means any kind of propagation that enables other
+parties to make or receive copies.  Mere interaction with a user through
+a computer network, with no transfer of a copy, is not conveying.
+
+  An interactive user interface displays "Appropriate Legal Notices"
+to the extent that it includes a convenient and prominently visible
+feature that (1) displays an appropriate copyright notice, and (2)
+tells the user that there is no warranty for the work (except to the
+extent that warranties are provided), that licensees may convey the
+work under this License, and how to view a copy of this License.  If
+the interface presents a list of user commands or options, such as a
+menu, a prominent item in the list meets this criterion.
+
+  1. Source Code.
+
+  The "source code" for a work means the preferred form of the work
+for making modifications to it.  "Object code" means any non-source
+form of a work.
+
+  A "Standard Interface" means an interface that either is an official
+standard defined by a recognized standards body, or, in the case of
+interfaces specified for a particular programming language, one that
+is widely used among developers working in that language.
+
+  The "System Libraries" of an executable work include anything, other
+than the work as a whole, that (a) is included in the normal form of
+packaging a Major Component, but which is not part of that Major
+Component, and (b) serves only to enable use of the work with that
+Major Component, or to implement a Standard Interface for which an
+implementation is available to the public in source code form.  A
+"Major Component", in this context, means a major essential component
+(kernel, window system, and so on) of the specific operating system
+(if any) on which the executable work runs, or a compiler used to
+produce the work, or an object code interpreter used to run it.
+
+  The "Corresponding Source" for a work in object code form means all
+the source code needed to generate, install, and (for an executable
+work) run the object code and to modify the work, including scripts to
+control those activities.  However, it does not include the work's
+System Libraries, or general-purpose tools or generally available free
+programs which are used unmodified in performing those activities but
+which are not part of the work.  For example, Corresponding Source
+includes interface definition files associated with source files for
+the work, and the source code for shared libraries and dynamically
+linked subprograms that the work is specifically designed to require,
+such as by intimate data communication or control flow between those
+subprograms and other parts of the work.
+
+  The Corresponding Source need not include anything that users
+can regenerate automatically from other parts of the Corresponding
+Source.
+
+  The Corresponding Source for a work in source code form is that
+same work.
+
+  2. Basic Permissions.
+
+  All rights granted under this License are granted for the term of
+copyright on the Program, and are irrevocable provided the stated
+conditions are met.  This License explicitly affirms your unlimited
+permission to run the unmodified Program.  The output from running a
+covered work is covered by this License only if the output, given its
+content, constitutes a covered work.  This License acknowledges your
+rights of fair use or other equivalent, as provided by copyright law.
+
+  You may make, run and propagate covered works that you do not
+convey, without conditions so long as your license otherwise remains
+in force.  You may convey covered works to others for the sole purpose
+of having them make modifications exclusively for you, or provide you
+with facilities for running those works, provided that you comply with
+the terms of this License in conveying all material for which you do
+not control copyright.  Those thus making or running the covered works
+for you must do so exclusively on your behalf, under your direction
+and control, on terms that prohibit them from making any copies of
+your copyrighted material outside their relationship with you.
+
+  Conveying under any other circumstances is permitted solely under
+the conditions stated below.  Sublicensing is not allowed; section 10
+makes it unnecessary.
+
+  3. Protecting Users' Legal Rights From Anti-Circumvention Law.
+
+  No covered work shall be deemed part of an effective technological
+measure under any applicable law fulfilling obligations under article
+11 of the WIPO copyright treaty adopted on 20 December 1996, or
+similar laws prohibiting or restricting circumvention of such
+measures.
+
+  When you convey a covered work, you waive any legal power to forbid
+circumvention of technological measures to the extent such circumvention
+is effected by exercising rights under this License with respect to
+the covered work, and you disclaim any intention to limit operation or
+modification of the work as a means of enforcing, against the work's
+users, your or third parties' legal rights to forbid circumvention of
+technological measures.
+
+  4. Conveying Verbatim Copies.
+
+  You may convey verbatim copies of the Program's source code as you
+receive it, in any medium, provided that you conspicuously and
+appropriately publish on each copy an appropriate copyright notice;
+keep intact all notices stating that this License and any
+non-permissive terms added in accord with section 7 apply to the code;
+keep intact all notices of the absence of any warranty; and give all
+recipients a copy of this License along with the Program.
+
+  You may charge any price or no price for each copy that you convey,
+and you may offer support or warranty protection for a fee.
+
+  5. Conveying Modified Source Versions.
+
+  You may convey a work based on the Program, or the modifications to
+produce it from the Program, in the form of source code under the
+terms of section 4, provided that you also meet all of these conditions:
+
+    a) The work must carry prominent notices stating that you modified
+    it, and giving a relevant date.
+
+    b) The work must carry prominent notices stating that it is
+    released under this License and any conditions added under section
+    7.  This requirement modifies the requirement in section 4 to
+    "keep intact all notices".
+
+    c) You must license the entire work, as a whole, under this
+    License to anyone who comes into possession of a copy.  This
+    License will therefore apply, along with any applicable section 7
+    additional terms, to the whole of the work, and all its parts,
+    regardless of how they are packaged.  This License gives no
+    permission to license the work in any other way, but it does not
+    invalidate such permission if you have separately received it.
+
+    d) If the work has interactive user interfaces, each must display
+    Appropriate Legal Notices; however, if the Program has interactive
+    interfaces that do not display Appropriate Legal Notices, your
+    work need not make them do so.
+
+  A compilation of a covered work with other separate and independent
+works, which are not by their nature extensions of the covered work,
+and which are not combined with it such as to form a larger program,
+in or on a volume of a storage or distribution medium, is called an
+"aggregate" if the compilation and its resulting copyright are not
+used to limit the access or legal rights of the compilation's users
+beyond what the individual works permit.  Inclusion of a covered work
+in an aggregate does not cause this License to apply to the other
+parts of the aggregate.
+
+  6. Conveying Non-Source Forms.
+
+  You may convey a covered work in object code form under the terms
+of sections 4 and 5, provided that you also convey the
+machine-readable Corresponding Source under the terms of this License,
+in one of these ways:
+
+    a) Convey the object code in, or embodied in, a physical product
+    (including a physical distribution medium), accompanied by the
+    Corresponding Source fixed on a durable physical medium
+    customarily used for software interchange.
+
+    b) Convey the object code in, or embodied in, a physical product
+    (including a physical distribution medium), accompanied by a
+    written offer, valid for at least three years and valid for as
+    long as you offer spare parts or customer support for that product
+    model, to give anyone who possesses the object code either (1) a
+    copy of the Corresponding Source for all the software in the
+    product that is covered by this License, on a durable physical
+    medium customarily used for software interchange, for a price no
+    more than your reasonable cost of physically performing this
+    conveying of source, or (2) access to copy the
+    Corresponding Source from a network server at no charge.
+
+    c) Convey individual copies of the object code with a copy of the
+    written offer to provide the Corresponding Source.  This
+    alternative is allowed only occasionally and noncommercially, and
+    only if you received the object code with such an offer, in accord
+    with subsection 6b.
+
+    d) Convey the object code by offering access from a designated
+    place (gratis or for a charge), and offer equivalent access to the
+    Corresponding Source in the same way through the same place at no
+    further charge.  You need not require recipients to copy the
+    Corresponding Source along with the object code.  If the place to
+    copy the object code is a network server, the Corresponding Source
+    may be on a different server (operated by you or a third party)
+    that supports equivalent copying facilities, provided you maintain
+    clear directions next to the object code saying where to find the
+    Corresponding Source.  Regardless of what server hosts the
+    Corresponding Source, you remain obligated to ensure that it is
+    available for as long as needed to satisfy these requirements.
+
+    e) Convey the object code using peer-to-peer transmission, provided
+    you inform other peers where the object code and Corresponding
+    Source of the work are being offered to the general public at no
+    charge under subsection 6d.
+
+  A separable portion of the object code, whose source code is excluded
+from the Corresponding Source as a System Library, need not be
+included in conveying the object code work.
+
+  A "User Product" is either (1) a "consumer product", which means any
+tangible personal property which is normally used for personal, family,
+or household purposes, or (2) anything designed or sold for incorporation
+into a dwelling.  In determining whether a product is a consumer product,
+doubtful cases shall be resolved in favor of coverage.  For a particular
+product received by a particular user, "normally used" refers to a
+typical or common use of that class of product, regardless of the status
+of the particular user or of the way in which the particular user
+actually uses, or expects or is expected to use, the product.  A product
+is a consumer product regardless of whether the product has substantial
+commercial, industrial or non-consumer uses, unless such uses represent
+the only significant mode of use of the product.
+
+  "Installation Information" for a User Product means any methods,
+procedures, authorization keys, or other information required to install
+and execute modified versions of a covered work in that User Product from
+a modified version of its Corresponding Source.  The information must
+suffice to ensure that the continued functioning of the modified object
+code is in no case prevented or interfered with solely because
+modification has been made.
+
+  If you convey an object code work under this section in, or with, or
+specifically for use in, a User Product, and the conveying occurs as
+part of a transaction in which the right of possession and use of the
+User Product is transferred to the recipient in perpetuity or for a
+fixed term (regardless of how the transaction is characterized), the
+Corresponding Source conveyed under this section must be accompanied
+by the Installation Information.  But this requirement does not apply
+if neither you nor any third party retains the ability to install
+modified object code on the User Product (for example, the work has
+been installed in ROM).
+
+  The requirement to provide Installation Information does not include a
+requirement to continue to provide support service, warranty, or updates
+for a work that has been modified or installed by the recipient, or for
+the User Product in which it has been modified or installed.  Access to a
+network may be denied when the modification itself materially and
+adversely affects the operation of the network or violates the rules and
+protocols for communication across the network.
+
+  Corresponding Source conveyed, and Installation Information provided,
+in accord with this section must be in a format that is publicly
+documented (and with an implementation available to the public in
+source code form), and must require no special password or key for
+unpacking, reading or copying.
+
+  7. Additional Terms.
+
+  "Additional permissions" are terms that supplement the terms of this
+License by making exceptions from one or more of its conditions.
+Additional permissions that are applicable to the entire Program shall
+be treated as though they were included in this License, to the extent
+that they are valid under applicable law.  If additional permissions
+apply only to part of the Program, that part may be used separately
+under those permissions, but the entire Program remains governed by
+this License without regard to the additional permissions.
+
+  When you convey a copy of a covered work, you may at your option
+remove any additional permissions from that copy, or from any part of
+it.  (Additional permissions may be written to require their own
+removal in certain cases when you modify the work.)  You may place
+additional permissions on material, added by you to a covered work,
+for which you have or can give appropriate copyright permission.
+
+  Notwithstanding any other provision of this License, for material you
+add to a covered work, you may (if authorized by the copyright holders of
+that material) supplement the terms of this License with terms:
+
+    a) Disclaiming warranty or limiting liability differently from the
+    terms of sections 15 and 16 of this License; or
+
+    b) Requiring preservation of specified reasonable legal notices or
+    author attributions in that material or in the Appropriate Legal
+    Notices displayed by works containing it; or
+
+    c) Prohibiting misrepresentation of the origin of that material, or
+    requiring that modified versions of such material be marked in
+    reasonable ways as different from the original version; or
+
+    d) Limiting the use for publicity purposes of names of licensors or
+    authors of the material; or
+
+    e) Declining to grant rights under trademark law for use of some
+    trade names, trademarks, or service marks; or
+
+    f) Requiring indemnification of licensors and authors of that
+    material by anyone who conveys the material (or modified versions of
+    it) with contractual assumptions of liability to the recipient, for
+    any liability that these contractual assumptions directly impose on
+    those licensors and authors.
+
+  All other non-permissive additional terms are considered "further
+restrictions" within the meaning of section 10.  If the Program as you
+received it, or any part of it, contains a notice stating that it is
+governed by this License along with a term that is a further
+restriction, you may remove that term.  If a license document contains
+a further restriction but permits relicensing or conveying under this
+License, you may add to a covered work material governed by the terms
+of that license document, provided that the further restriction does
+not survive such relicensing or conveying.
+
+  If you add terms to a covered work in accord with this section, you
+must place, in the relevant source files, a statement of the
+additional terms that apply to those files, or a notice indicating
+where to find the applicable terms.
+
+  Additional terms, permissive or non-permissive, may be stated in the
+form of a separately written license, or stated as exceptions;
+the above requirements apply either way.
+
+  8. Termination.
+
+  You may not propagate or modify a covered work except as expressly
+provided under this License.  Any attempt otherwise to propagate or
+modify it is void, and will automatically terminate your rights under
+this License (including any patent licenses granted under the third
+paragraph of section 11).
+
+  However, if you cease all violation of this License, then your
+license from a particular copyright holder is reinstated (a)
+provisionally, unless and until the copyright holder explicitly and
+finally terminates your license, and (b) permanently, if the copyright
+holder fails to notify you of the violation by some reasonable means
+prior to 60 days after the cessation.
+
+  Moreover, your license from a particular copyright holder is
+reinstated permanently if the copyright holder notifies you of the
+violation by some reasonable means, this is the first time you have
+received notice of violation of this License (for any work) from that
+copyright holder, and you cure the violation prior to 30 days after
+your receipt of the notice.
+
+  Termination of your rights under this section does not terminate the
+licenses of parties who have received copies or rights from you under
+this License.  If your rights have been terminated and not permanently
+reinstated, you do not qualify to receive new licenses for the same
+material under section 10.
+
+  9. Acceptance Not Required for Having Copies.
+
+  You are not required to accept this License in order to receive or
+run a copy of the Program.  Ancillary propagation of a covered work
+occurring solely as a consequence of using peer-to-peer transmission
+to receive a copy likewise does not require acceptance.  However,
+nothing other than this License grants you permission to propagate or
+modify any covered work.  These actions infringe copyright if you do
+not accept this License.  Therefore, by modifying or propagating a
+covered work, you indicate your acceptance of this License to do so.
+
+  10. Automatic Licensing of Downstream Recipients.
+
+  Each time you convey a covered work, the recipient automatically
+receives a license from the original licensors, to run, modify and
+propagate that work, subject to this License.  You are not responsible
+for enforcing compliance by third parties with this License.
+
+  An "entity transaction" is a transaction transferring control of an
+organization, or substantially all assets of one, or subdividing an
+organization, or merging organizations.  If propagation of a covered
+work results from an entity transaction, each party to that
+transaction who receives a copy of the work also receives whatever
+licenses to the work the party's predecessor in interest had or could
+give under the previous paragraph, plus a right to possession of the
+Corresponding Source of the work from the predecessor in interest, if
+the predecessor has it or can get it with reasonable efforts.
+
+  You may not impose any further restrictions on the exercise of the
+rights granted or affirmed under this License.  For example, you may
+not impose a license fee, royalty, or other charge for exercise of
+rights granted under this License, and you may not initiate litigation
+(including a cross-claim or counterclaim in a lawsuit) alleging that
+any patent claim is infringed by making, using, selling, offering for
+sale, or importing the Program or any portion of it.
+
+  11. Patents.
+
+  A "contributor" is a copyright holder who authorizes use under this
+License of the Program or a work on which the Program is based.  The
+work thus licensed is called the contributor's "contributor version".
+
+  A contributor's "essential patent claims" are all patent claims
+owned or controlled by the contributor, whether already acquired or
+hereafter acquired, that would be infringed by some manner, permitted
+by this License, of making, using, or selling its contributor version,
+but do not include claims that would be infringed only as a
+consequence of further modification of the contributor version.  For
+purposes of this definition, "control" includes the right to grant
+patent sublicenses in a manner consistent with the requirements of
+this License.
+
+  Each contributor grants you a non-exclusive, worldwide, royalty-free
+patent license under the contributor's essential patent claims, to
+make, use, sell, offer for sale, import and otherwise run, modify and
+propagate the contents of its contributor version.
+
+  In the following three paragraphs, a "patent license" is any express
+agreement or commitment, however denominated, not to enforce a patent
+(such as an express permission to practice a patent or covenant not to
+sue for patent infringement).  To "grant" such a patent license to a
+party means to make such an agreement or commitment not to enforce a
+patent against the party.
+
+  If you convey a covered work, knowingly relying on a patent license,
+and the Corresponding Source of the work is not available for anyone
+to copy, free of charge and under the terms of this License, through a
+publicly available network server or other readily accessible means,
+then you must either (1) cause the Corresponding Source to be so
+available, or (2) arrange to deprive yourself of the benefit of the
+patent license for this particular work, or (3) arrange, in a manner
+consistent with the requirements of this License, to extend the patent
+license to downstream recipients.  "Knowingly relying" means you have
+actual knowledge that, but for the patent license, your conveying the
+covered work in a country, or your recipient's use of the covered work
+in a country, would infringe one or more identifiable patents in that
+country that you have reason to believe are valid.
+
+  If, pursuant to or in connection with a single transaction or
+arrangement, you convey, or propagate by procuring conveyance of, a
+covered work, and grant a patent license to some of the parties
+receiving the covered work authorizing them to use, propagate, modify
+or convey a specific copy of the covered work, then the patent license
+you grant is automatically extended to all recipients of the covered
+work and works based on it.
+
+  A patent license is "discriminatory" if it does not include within
+the scope of its coverage, prohibits the exercise of, or is
+conditioned on the non-exercise of one or more of the rights that are
+specifically granted under this License.  You may not convey a covered
+work if you are a party to an arrangement with a third party that is
+in the business of distributing software, under which you make payment
+to the third party based on the extent of your activity of conveying
+the work, and under which the third party grants, to any of the
+parties who would receive the covered work from you, a discriminatory
+patent license (a) in connection with copies of the covered work
+conveyed by you (or copies made from those copies), or (b) primarily
+for and in connection with specific products or compilations that
+contain the covered work, unless you entered into that arrangement,
+or that patent license was granted, prior to 28 March 2007.
+
+  Nothing in this License shall be construed as excluding or limiting
+any implied license or other defenses to infringement that may
+otherwise be available to you under applicable patent law.
+
+  12. No Surrender of Others' Freedom.
+
+  If conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License.  If you cannot convey a
+covered work so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you may
+not convey it at all.  For example, if you agree to terms that obligate you
+to collect a royalty for further conveying from those to whom you convey
+the Program, the only way you could satisfy both those terms and this
+License would be to refrain entirely from conveying the Program.
+
+  13. Use with the GNU Affero General Public License.
+
+  Notwithstanding any other provision of this License, you have
+permission to link or combine any covered work with a work licensed
+under version 3 of the GNU Affero General Public License into a single
+combined work, and to convey the resulting work.  The terms of this
+License will continue to apply to the part which is the covered work,
+but the special requirements of the GNU Affero General Public License,
+section 13, concerning interaction through a network will apply to the
+combination as such.
+
+  14. Revised Versions of this License.
+
+  The Free Software Foundation may publish revised and/or new versions of
+the GNU General Public License from time to time.  Such new versions will
+be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.
+
+  Each version is given a distinguishing version number.  If the
+Program specifies that a certain numbered version of the GNU General
+Public License "or any later version" applies to it, you have the
+option of following the terms and conditions either of that numbered
+version or of any later version published by the Free Software
+Foundation.  If the Program does not specify a version number of the
+GNU General Public License, you may choose any version ever published
+by the Free Software Foundation.
+
+  If the Program specifies that a proxy can decide which future
+versions of the GNU General Public License can be used, that proxy's
+public statement of acceptance of a version permanently authorizes you
+to choose that version for the Program.
+
+  Later license versions may give you additional or different
+permissions.  However, no additional obligations are imposed on any
+author or copyright holder as a result of your choosing to follow a
+later version.
+
+  15. Disclaimer of Warranty.
+
+  THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
+APPLICABLE LAW.  EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
+HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY
+OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
+THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
+PURPOSE.  THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM
+IS WITH YOU.  SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
+ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
+
+  16. Limitation of Liability.
+
+  IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
+THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
+GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE
+USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF
+DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
+PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),
+EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF
+SUCH DAMAGES.
+
+  17. Interpretation of Sections 15 and 16.
+
+  If the disclaimer of warranty and limitation of liability provided
+above cannot be given local legal effect according to their terms,
+reviewing courts shall apply local law that most closely approximates
+an absolute waiver of all civil liability in connection with the
+Program, unless a warranty or assumption of liability accompanies a
+copy of the Program in return for a fee.
+
+                     END OF TERMS AND CONDITIONS

+Georeferencing
+==============
+
+In the AEC industry, works in the built environment are split between vertical
+construction (such as buildings and sites), and horizontal construction (such as
+transit, transmission, and subterranean networks). Blender and the BlenderBIM
+Add-on is only suitable for vertical construction.
+
+IFC4 onwards supports georeferencing. The BlenderBIM Add-on has full support for
+IFC georeferencing. Here are the potential scenarios you will encounter in the
+wild for vertical construction.
+
+1. Correctly georeferenced IFC4 with a map conversion transformation
+2. Correctly georeferenced IFC4 without a map conversion transformation
+3. Non-georeferenced georeferenced IFC4
+4. Non-georeferenced IFC2X3
+
+The first scenario is desired for most disciplines, such as architects and all
+engineers (except for civil).
+
+For scenarios 2, 3, and 4, the BlenderBIM Add-on will automatically attempt to
+offset coordinates to preserve the precision of the model. The first coordinate
+greater than 1km will be detected and used as an offset coordinate. It is
+possible to specify a custom offset coordinate.
+
+Non-georeferenced workarounds
+-----------------------------
+
+The unfortunate reality is that IFC2X3 does not support georeferencing, and most
+vendors have poor and inconsistent support for georeferencing, even in IFC4.
+Some users may be under the impression that their file is correctly
+georeferenced, but this is rarely the case. This creates problems. You can see
+whether your file is correctly georeferenced in the ``IFC Georeferencing``
+scene panel. If you see "Not Georeferenced", your file is not correctly
+georeferenced. If your file is georeferenced, it is no guarantee that the
+georeferencing data is actually correct, but how to determine this is out of
+scope of this article.
+
+As an invalid workaround for correct georeferencing, many other BIM vendors
+simply offset their object coordinates from local engineering to map coordinates
+without properly storing a projection system and optionally a map
+transformation. There are two common invalid workarounds that are used.
+
+The first invalid workaround is to shift the origin point of objects in the
+model. We call this the ``OBJECT_PLACEMENT`` workaround. The second invalid
+workaround is to shift the coordinates of geometry within the objects
+themselves, and typically leave the object origin untouched (such as back at (0,
+0, 0)). We call this the ``CARTESIAN_POINT`` workaround. Sometimes, BIM
+applications combine both of these invalid workarounds. To see which workaround
+was used on an object, check the "Blender Offset" property in the ``Transform``
+object panel.
+
+Coordinates and precision limits
+--------------------------------
+
+Blender, and subsequently the BlenderBIM Add-on, is not designed for map
+coordinate systems. Blender internally uses single precision floating point
+calculations. A full description of the precision implications are described in
+the `Blender working limits documentation
+<https://docs.blender.org/manual/en/latest/advanced/limits.html>`__.
+
+From a software perspective, lengths greater than 5,000 meters start to
+accumulate precision errors that affect the nearest millimeter. Therefore, from
+a software perspective, it is unwise to embark on a project with coordinates
+ranging greater than +/- 5km.
+
+However, if working in local engineering coordinates, a single transformation is
+required to convert from local engineering coordinates to map coordinates. This
+transformation includes a scale factor. The scale factor is only assumed to be
+constant for small sites (defined approximately as less than 1km square).
+This practical limit of georeferenced vertical construction is smaller than the
+software limit, so this is the actual limiting factor.

+                    GNU GENERAL PUBLIC LICENSE
+                       Version 3, 29 June 2007
+
+ Copyright (C) 2007 Free Software Foundation, Inc. <https://fsf.org/>
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+                            Preamble
+
+  The GNU General Public License is a free, copyleft license for
+software and other kinds of works.
+
+  The licenses for most software and other practical works are designed
+to take away your freedom to share and change the works.  By contrast,
+the GNU General Public License is intended to guarantee your freedom to
+share and change all versions of a program--to make sure it remains free
+software for all its users.  We, the Free Software Foundation, use the
+GNU General Public License for most of our software; it applies also to
+any other work released this way by its authors.  You can apply it to
+your programs, too.
+
+  When we speak of free software, we are referring to freedom, not
+price.  Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+them if you wish), that you receive source code or can get it if you
+want it, that you can change the software or use pieces of it in new
+free programs, and that you know you can do these things.
+
+  To protect your rights, we need to prevent others from denying you
+these rights or asking you to surrender the rights.  Therefore, you have
+certain responsibilities if you distribute copies of the software, or if
+you modify it: responsibilities to respect the freedom of others.
+
+  For example, if you distribute copies of such a program, whether
+gratis or for a fee, you must pass on to the recipients the same
+freedoms that you received.  You must make sure that they, too, receive
+or can get the source code.  And you must show them these terms so they
+know their rights.
+
+  Developers that use the GNU GPL protect your rights with two steps:
+(1) assert copyright on the software, and (2) offer you this License
+giving you legal permission to copy, distribute and/or modify it.
+
+  For the developers' and authors' protection, the GPL clearly explains
+that there is no warranty for this free software.  For both users' and
+authors' sake, the GPL requires that modified versions be marked as
+changed, so that their problems will not be attributed erroneously to
+authors of previous versions.
+
+  Some devices are designed to deny users access to install or run
+modified versions of the software inside them, although the manufacturer
+can do so.  This is fundamentally incompatible with the aim of
+protecting users' freedom to change the software.  The systematic
+pattern of such abuse occurs in the area of products for individuals to
+use, which is precisely where it is most unacceptable.  Therefore, we
+have designed this version of the GPL to prohibit the practice for those
+products.  If such problems arise substantially in other domains, we
+stand ready to extend this provision to those domains in future versions
+of the GPL, as needed to protect the freedom of users.
+
+  Finally, every program is threatened constantly by software patents.
+States should not allow patents to restrict development and use of
+software on general-purpose computers, but in those that do, we wish to
+avoid the special danger that patents applied to a free program could
+make it effectively proprietary.  To prevent this, the GPL assures that
+patents cannot be used to render the program non-free.
+
+  The precise terms and conditions for copying, distribution and
+modification follow.
+
+                       TERMS AND CONDITIONS
+
+  0. Definitions.
+
+  "This License" refers to version 3 of the GNU General Public License.
+
+  "Copyright" also means copyright-like laws that apply to other kinds of
+works, such as semiconductor masks.
+
+  "The Program" refers to any copyrightable work licensed under this
+License.  Each licensee is addressed as "you".  "Licensees" and
+"recipients" may be individuals or organizations.
+
+  To "modify" a work means to copy from or adapt all or part of the work
+in a fashion requiring copyright permission, other than the making of an
+exact copy.  The resulting work is called a "modified version" of the
+earlier work or a work "based on" the earlier work.
+
+  A "covered work" means either the unmodified Program or a work based
+on the Program.
+
+  To "propagate" a work means to do anything with it that, without
+permission, would make you directly or secondarily liable for
+infringement under applicable copyright law, except executing it on a
+computer or modifying a private copy.  Propagation includes copying,
+distribution (with or without modification), making available to the
+public, and in some countries other activities as well.
+
+  To "convey" a work means any kind of propagation that enables other
+parties to make or receive copies.  Mere interaction with a user through
+a computer network, with no transfer of a copy, is not conveying.
+
+  An interactive user interface displays "Appropriate Legal Notices"
+to the extent that it includes a convenient and prominently visible
+feature that (1) displays an appropriate copyright notice, and (2)
+tells the user that there is no warranty for the work (except to the
+extent that warranties are provided), that licensees may convey the
+work under this License, and how to view a copy of this License.  If
+the interface presents a list of user commands or options, such as a
+menu, a prominent item in the list meets this criterion.
+
+  1. Source Code.
+
+  The "source code" for a work means the preferred form of the work
+for making modifications to it.  "Object code" means any non-source
+form of a work.
+
+  A "Standard Interface" means an interface that either is an official
+standard defined by a recognized standards body, or, in the case of
+interfaces specified for a particular programming language, one that
+is widely used among developers working in that language.
+
+  The "System Libraries" of an executable work include anything, other
+than the work as a whole, that (a) is included in the normal form of
+packaging a Major Component, but which is not part of that Major
+Component, and (b) serves only to enable use of the work with that
+Major Component, or to implement a Standard Interface for which an
+implementation is available to the public in source code form.  A
+"Major Component", in this context, means a major essential component
+(kernel, window system, and so on) of the specific operating system
+(if any) on which the executable work runs, or a compiler used to
+produce the work, or an object code interpreter used to run it.
+
+  The "Corresponding Source" for a work in object code form means all
+the source code needed to generate, install, and (for an executable
+work) run the object code and to modify the work, including scripts to
+control those activities.  However, it does not include the work's
+System Libraries, or general-purpose tools or generally available free
+programs which are used unmodified in performing those activities but
+which are not part of the work.  For example, Corresponding Source
+includes interface definition files associated with source files for
+the work, and the source code for shared libraries and dynamically
+linked subprograms that the work is specifically designed to require,
+such as by intimate data communication or control flow between those
+subprograms and other parts of the work.
+
+  The Corresponding Source need not include anything that users
+can regenerate automatically from other parts of the Corresponding
+Source.
+
+  The Corresponding Source for a work in source code form is that
+same work.
+
+  2. Basic Permissions.
+
+  All rights granted under this License are granted for the term of
+copyright on the Program, and are irrevocable provided the stated
+conditions are met.  This License explicitly affirms your unlimited
+permission to run the unmodified Program.  The output from running a
+covered work is covered by this License only if the output, given its
+content, constitutes a covered work.  This License acknowledges your
+rights of fair use or other equivalent, as provided by copyright law.
+
+  You may make, run and propagate covered works that you do not
+convey, without conditions so long as your license otherwise remains
+in force.  You may convey covered works to others for the sole purpose
+of having them make modifications exclusively for you, or provide you
+with facilities for running those works, provided that you comply with
+the terms of this License in conveying all material for which you do
+not control copyright.  Those thus making or running the covered works
+for you must do so exclusively on your behalf, under your direction
+and control, on terms that prohibit them from making any copies of
+your copyrighted material outside their relationship with you.
+
+  Conveying under any other circumstances is permitted solely under
+the conditions stated below.  Sublicensing is not allowed; section 10
+makes it unnecessary.
+
+  3. Protecting Users' Legal Rights From Anti-Circumvention Law.
+
+  No covered work shall be deemed part of an effective technological
+measure under any applicable law fulfilling obligations under article
+11 of the WIPO copyright treaty adopted on 20 December 1996, or
+similar laws prohibiting or restricting circumvention of such
+measures.
+
+  When you convey a covered work, you waive any legal power to forbid
+circumvention of technological measures to the extent such circumvention
+is effected by exercising rights under this License with respect to
+the covered work, and you disclaim any intention to limit operation or
+modification of the work as a means of enforcing, against the work's
+users, your or third parties' legal rights to forbid circumvention of
+technological measures.
+
+  4. Conveying Verbatim Copies.
+
+  You may convey verbatim copies of the Program's source code as you
+receive it, in any medium, provided that you conspicuously and
+appropriately publish on each copy an appropriate copyright notice;
+keep intact all notices stating that this License and any
+non-permissive terms added in accord with section 7 apply to the code;
+keep intact all notices of the absence of any warranty; and give all
+recipients a copy of this License along with the Program.
+
+  You may charge any price or no price for each copy that you convey,
+and you may offer support or warranty protection for a fee.
+
+  5. Conveying Modified Source Versions.
+
+  You may convey a work based on the Program, or the modifications to
+produce it from the Program, in the form of source code under the
+terms of section 4, provided that you also meet all of these conditions:
+
+    a) The work must carry prominent notices stating that you modified
+    it, and giving a relevant date.
+
+    b) The work must carry prominent notices stating that it is
+    released under this License and any conditions added under section
+    7.  This requirement modifies the requirement in section 4 to
+    "keep intact all notices".
+
+    c) You must license the entire work, as a whole, under this
+    License to anyone who comes into possession of a copy.  This
+    License will therefore apply, along with any applicable section 7
+    additional terms, to the whole of the work, and all its parts,
+    regardless of how they are packaged.  This License gives no
+    permission to license the work in any other way, but it does not
+    invalidate such permission if you have separately received it.
+
+    d) If the work has interactive user interfaces, each must display
+    Appropriate Legal Notices; however, if the Program has interactive
+    interfaces that do not display Appropriate Legal Notices, your
+    work need not make them do so.
+
+  A compilation of a covered work with other separate and independent
+works, which are not by their nature extensions of the covered work,
+and which are not combined with it such as to form a larger program,
+in or on a volume of a storage or distribution medium, is called an
+"aggregate" if the compilation and its resulting copyright are not
+used to limit the access or legal rights of the compilation's users
+beyond what the individual works permit.  Inclusion of a covered work
+in an aggregate does not cause this License to apply to the other
+parts of the aggregate.
+
+  6. Conveying Non-Source Forms.
+
+  You may convey a covered work in object code form under the terms
+of sections 4 and 5, provided that you also convey the
+machine-readable Corresponding Source under the terms of this License,
+in one of these ways:
+
+    a) Convey the object code in, or embodied in, a physical product
+    (including a physical distribution medium), accompanied by the
+    Corresponding Source fixed on a durable physical medium
+    customarily used for software interchange.
+
+    b) Convey the object code in, or embodied in, a physical product
+    (including a physical distribution medium), accompanied by a
+    written offer, valid for at least three years and valid for as
+    long as you offer spare parts or customer support for that product
+    model, to give anyone who possesses the object code either (1) a
+    copy of the Corresponding Source for all the software in the
+    product that is covered by this License, on a durable physical
+    medium customarily used for software interchange, for a price no
+    more than your reasonable cost of physically performing this
+    conveying of source, or (2) access to copy the
+    Corresponding Source from a network server at no charge.
+
+    c) Convey individual copies of the object code with a copy of the
+    written offer to provide the Corresponding Source.  This
+    alternative is allowed only occasionally and noncommercially, and
+    only if you received the object code with such an offer, in accord
+    with subsection 6b.
+
+    d) Convey the object code by offering access from a designated
+    place (gratis or for a charge), and offer equivalent access to the
+    Corresponding Source in the same way through the same place at no
+    further charge.  You need not require recipients to copy the
+    Corresponding Source along with the object code.  If the place to
+    copy the object code is a network server, the Corresponding Source
+    may be on a different server (operated by you or a third party)
+    that supports equivalent copying facilities, provided you maintain
+    clear directions next to the object code saying where to find the
+    Corresponding Source.  Regardless of what server hosts the
+    Corresponding Source, you remain obligated to ensure that it is
+    available for as long as needed to satisfy these requirements.
+
+    e) Convey the object code using peer-to-peer transmission, provided
+    you inform other peers where the object code and Corresponding
+    Source of the work are being offered to the general public at no
+    charge under subsection 6d.
+
+  A separable portion of the object code, whose source code is excluded
+from the Corresponding Source as a System Library, need not be
+included in conveying the object code work.
+
+  A "User Product" is either (1) a "consumer product", which means any
+tangible personal property which is normally used for personal, family,
+or household purposes, or (2) anything designed or sold for incorporation
+into a dwelling.  In determining whether a product is a consumer product,
+doubtful cases shall be resolved in favor of coverage.  For a particular
+product received by a particular user, "normally used" refers to a
+typical or common use of that class of product, regardless of the status
+of the particular user or of the way in which the particular user
+actually uses, or expects or is expected to use, the product.  A product
+is a consumer product regardless of whether the product has substantial
+commercial, industrial or non-consumer uses, unless such uses represent
+the only significant mode of use of the product.
+
+  "Installation Information" for a User Product means any methods,
+procedures, authorization keys, or other information required to install
+and execute modified versions of a covered work in that User Product from
+a modified version of its Corresponding Source.  The information must
+suffice to ensure that the continued functioning of the modified object
+code is in no case prevented or interfered with solely because
+modification has been made.
+
+  If you convey an object code work under this section in, or with, or
+specifically for use in, a User Product, and the conveying occurs as
+part of a transaction in which the right of possession and use of the
+User Product is transferred to the recipient in perpetuity or for a
+fixed term (regardless of how the transaction is characterized), the
+Corresponding Source conveyed under this section must be accompanied
+by the Installation Information.  But this requirement does not apply
+if neither you nor any third party retains the ability to install
+modified object code on the User Product (for example, the work has
+been installed in ROM).
+
+  The requirement to provide Installation Information does not include a
+requirement to continue to provide support service, warranty, or updates
+for a work that has been modified or installed by the recipient, or for
+the User Product in which it has been modified or installed.  Access to a
+network may be denied when the modification itself materially and
+adversely affects the operation of the network or violates the rules and
+protocols for communication across the network.
+
+  Corresponding Source conveyed, and Installation Information provided,
+in accord with this section must be in a format that is publicly
+documented (and with an implementation available to the public in
+source code form), and must require no special password or key for
+unpacking, reading or copying.
+
+  7. Additional Terms.
+
+  "Additional permissions" are terms that supplement the terms of this
+License by making exceptions from one or more of its conditions.
+Additional permissions that are applicable to the entire Program shall
+be treated as though they were included in this License, to the extent
+that they are valid under applicable law.  If additional permissions
+apply only to part of the Program, that part may be used separately
+under those permissions, but the entire Program remains governed by
+this License without regard to the additional permissions.
+
+  When you convey a copy of a covered work, you may at your option
+remove any additional permissions from that copy, or from any part of
+it.  (Additional permissions may be written to require their own
+removal in certain cases when you modify the work.)  You may place
+additional permissions on material, added by you to a covered work,
+for which you have or can give appropriate copyright permission.
+
+  Notwithstanding any other provision of this License, for material you
+add to a covered work, you may (if authorized by the copyright holders of
+that material) supplement the terms of this License with terms:
+
+    a) Disclaiming warranty or limiting liability differently from the
+    terms of sections 15 and 16 of this License; or
+
+    b) Requiring preservation of specified reasonable legal notices or
+    author attributions in that material or in the Appropriate Legal
+    Notices displayed by works containing it; or
+
+    c) Prohibiting misrepresentation of the origin of that material, or
+    requiring that modified versions of such material be marked in
+    reasonable ways as different from the original version; or
+
+    d) Limiting the use for publicity purposes of names of licensors or
+    authors of the material; or
+
+    e) Declining to grant rights under trademark law for use of some
+    trade names, trademarks, or service marks; or
+
+    f) Requiring indemnification of licensors and authors of that
+    material by anyone who conveys the material (or modified versions of
+    it) with contractual assumptions of liability to the recipient, for
+    any liability that these contractual assumptions directly impose on
+    those licensors and authors.
+
+  All other non-permissive additional terms are considered "further
+restrictions" within the meaning of section 10.  If the Program as you
+received it, or any part of it, contains a notice stating that it is
+governed by this License along with a term that is a further
+restriction, you may remove that term.  If a license document contains
+a further restriction but permits relicensing or conveying under this
+License, you may add to a covered work material governed by the terms
+of that license document, provided that the further restriction does
+not survive such relicensing or conveying.
+
+  If you add terms to a covered work in accord with this section, you
+must place, in the relevant source files, a statement of the
+additional terms that apply to those files, or a notice indicating
+where to find the applicable terms.
+
+  Additional terms, permissive or non-permissive, may be stated in the
+form of a separately written license, or stated as exceptions;
+the above requirements apply either way.
+
+  8. Termination.
+
+  You may not propagate or modify a covered work except as expressly
+provided under this License.  Any attempt otherwise to propagate or
+modify it is void, and will automatically terminate your rights under
+this License (including any patent licenses granted under the third
+paragraph of section 11).
+
+  However, if you cease all violation of this License, then your
+license from a particular copyright holder is reinstated (a)
+provisionally, unless and until the copyright holder explicitly and
+finally terminates your license, and (b) permanently, if the copyright
+holder fails to notify you of the violation by some reasonable means
+prior to 60 days after the cessation.
+
+  Moreover, your license from a particular copyright holder is
+reinstated permanently if the copyright holder notifies you of the
+violation by some reasonable means, this is the first time you have
+received notice of violation of this License (for any work) from that
+copyright holder, and you cure the violation prior to 30 days after
+your receipt of the notice.
+
+  Termination of your rights under this section does not terminate the
+licenses of parties who have received copies or rights from you under
+this License.  If your rights have been terminated and not permanently
+reinstated, you do not qualify to receive new licenses for the same
+material under section 10.
+
+  9. Acceptance Not Required for Having Copies.
+
+  You are not required to accept this License in order to receive or
+run a copy of the Program.  Ancillary propagation of a covered work
+occurring solely as a consequence of using peer-to-peer transmission
+to receive a copy likewise does not require acceptance.  However,
+nothing other than this License grants you permission to propagate or
+modify any covered work.  These actions infringe copyright if you do
+not accept this License.  Therefore, by modifying or propagating a
+covered work, you indicate your acceptance of this License to do so.
+
+  10. Automatic Licensing of Downstream Recipients.
+
+  Each time you convey a covered work, the recipient automatically
+receives a license from the original licensors, to run, modify and
+propagate that work, subject to this License.  You are not responsible
+for enforcing compliance by third parties with this License.
+
+  An "entity transaction" is a transaction transferring control of an
+organization, or substantially all assets of one, or subdividing an
+organization, or merging organizations.  If propagation of a covered
+work results from an entity transaction, each party to that
+transaction who receives a copy of the work also receives whatever
+licenses to the work the party's predecessor in interest had or could
+give under the previous paragraph, plus a right to possession of the
+Corresponding Source of the work from the predecessor in interest, if
+the predecessor has it or can get it with reasonable efforts.
+
+  You may not impose any further restrictions on the exercise of the
+rights granted or affirmed under this License.  For example, you may
+not impose a license fee, royalty, or other charge for exercise of
+rights granted under this License, and you may not initiate litigation
+(including a cross-claim or counterclaim in a lawsuit) alleging that
+any patent claim is infringed by making, using, selling, offering for
+sale, or importing the Program or any portion of it.
+
+  11. Patents.
+
+  A "contributor" is a copyright holder who authorizes use under this
+License of the Program or a work on which the Program is based.  The
+work thus licensed is called the contributor's "contributor version".
+
+  A contributor's "essential patent claims" are all patent claims
+owned or controlled by the contributor, whether already acquired or
+hereafter acquired, that would be infringed by some manner, permitted
+by this License, of making, using, or selling its contributor version,
+but do not include claims that would be infringed only as a
+consequence of further modification of the contributor version.  For
+purposes of this definition, "control" includes the right to grant
+patent sublicenses in a manner consistent with the requirements of
+this License.
+
+  Each contributor grants you a non-exclusive, worldwide, royalty-free
+patent license under the contributor's essential patent claims, to
+make, use, sell, offer for sale, import and otherwise run, modify and
+propagate the contents of its contributor version.
+
+  In the following three paragraphs, a "patent license" is any express
+agreement or commitment, however denominated, not to enforce a patent
+(such as an express permission to practice a patent or covenant not to
+sue for patent infringement).  To "grant" such a patent license to a
+party means to make such an agreement or commitment not to enforce a
+patent against the party.
+
+  If you convey a covered work, knowingly relying on a patent license,
+and the Corresponding Source of the work is not available for anyone
+to copy, free of charge and under the terms of this License, through a
+publicly available network server or other readily accessible means,
+then you must either (1) cause the Corresponding Source to be so
+available, or (2) arrange to deprive yourself of the benefit of the
+patent license for this particular work, or (3) arrange, in a manner
+consistent with the requirements of this License, to extend the patent
+license to downstream recipients.  "Knowingly relying" means you have
+actual knowledge that, but for the patent license, your conveying the
+covered work in a country, or your recipient's use of the covered work
+in a country, would infringe one or more identifiable patents in that
+country that you have reason to believe are valid.
+
+  If, pursuant to or in connection with a single transaction or
+arrangement, you convey, or propagate by procuring conveyance of, a
+covered work, and grant a patent license to some of the parties
+receiving the covered work authorizing them to use, propagate, modify
+or convey a specific copy of the covered work, then the patent license
+you grant is automatically extended to all recipients of the covered
+work and works based on it.
+
+  A patent license is "discriminatory" if it does not include within
+the scope of its coverage, prohibits the exercise of, or is
+conditioned on the non-exercise of one or more of the rights that are
+specifically granted under this License.  You may not convey a covered
+work if you are a party to an arrangement with a third party that is
+in the business of distributing software, under which you make payment
+to the third party based on the extent of your activity of conveying
+the work, and under which the third party grants, to any of the
+parties who would receive the covered work from you, a discriminatory
+patent license (a) in connection with copies of the covered work
+conveyed by you (or copies made from those copies), or (b) primarily
+for and in connection with specific products or compilations that
+contain the covered work, unless you entered into that arrangement,
+or that patent license was granted, prior to 28 March 2007.
+
+  Nothing in this License shall be construed as excluding or limiting
+any implied license or other defenses to infringement that may
+otherwise be available to you under applicable patent law.
+
+  12. No Surrender of Others' Freedom.
+
+  If conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License.  If you cannot convey a
+covered work so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you may
+not convey it at all.  For example, if you agree to terms that obligate you
+to collect a royalty for further conveying from those to whom you convey
+the Program, the only way you could satisfy both those terms and this
+License would be to refrain entirely from conveying the Program.
+
+  13. Use with the GNU Affero General Public License.
+
+  Notwithstanding any other provision of this License, you have
+permission to link or combine any covered work with a work licensed
+under version 3 of the GNU Affero General Public License into a single
+combined work, and to convey the resulting work.  The terms of this
+License will continue to apply to the part which is the covered work,
+but the special requirements of the GNU Affero General Public License,
+section 13, concerning interaction through a network will apply to the
+combination as such.
+
+  14. Revised Versions of this License.
+
+  The Free Software Foundation may publish revised and/or new versions of
+the GNU General Public License from time to time.  Such new versions will
+be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.
+
+  Each version is given a distinguishing version number.  If the
+Program specifies that a certain numbered version of the GNU General
+Public License "or any later version" applies to it, you have the
+option of following the terms and conditions either of that numbered
+version or of any later version published by the Free Software
+Foundation.  If the Program does not specify a version number of the
+GNU General Public License, you may choose any version ever published
+by the Free Software Foundation.
+
+  If the Program specifies that a proxy can decide which future
+versions of the GNU General Public License can be used, that proxy's
+public statement of acceptance of a version permanently authorizes you
+to choose that version for the Program.
+
+  Later license versions may give you additional or different
+permissions.  However, no additional obligations are imposed on any
+author or copyright holder as a result of your choosing to follow a
+later version.
+
+  15. Disclaimer of Warranty.
+
+  THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
+APPLICABLE LAW.  EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
+HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY
+OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
+THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
+PURPOSE.  THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM
+IS WITH YOU.  SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
+ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
+
+  16. Limitation of Liability.
+
+  IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
+THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
+GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE
+USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF
+DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
+PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),
+EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF
+SUCH DAMAGES.
+
+  17. Interpretation of Sections 15 and 16.
+
+  If the disclaimer of warranty and limitation of liability provided
+above cannot be given local legal effect according to their terms,
+reviewing courts shall apply local law that most closely approximates
+an absolute waiver of all civil liability in connection with the
+Program, unless a warranty or assumption of liability accompanies a
+copy of the Program in return for a fee.
+
+                     END OF TERMS AND CONDITIONS

+                       Version 3, 29 June 2007
+
+ Copyright (C) 2007 Free Software Foundation, Inc. <https://fsf.org/>
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+
+  This version of the GNU Lesser General Public License incorporates
+the terms and conditions of version 3 of the GNU General Public
+License, supplemented by the additional permissions listed below.
+
+  0. Additional Definitions.
+
+  As used herein, "this License" refers to version 3 of the GNU Lesser
+General Public License, and the "GNU GPL" refers to version 3 of the GNU
+General Public License.
+
+  "The Library" refers to a covered work governed by this License,
+other than an Application or a Combined Work as defined below.
+
+  An "Application" is any work that makes use of an interface provided
+by the Library, but which is not otherwise based on the Library.
+Defining a subclass of a class defined by the Library is deemed a mode
+of using an interface provided by the Library.
+
+  A "Combined Work" is a work produced by combining or linking an
+Application with the Library.  The particular version of the Library
+with which the Combined Work was made is also called the "Linked
+Version".
+
+  The "Minimal Corresponding Source" for a Combined Work means the
+Corresponding Source for the Combined Work, excluding any source code
+for portions of the Combined Work that, considered in isolation, are
+based on the Application, and not on the Linked Version.
+
+  The "Corresponding Application Code" for a Combined Work means the
+object code and/or source code for the Application, including any data
+and utility programs needed for reproducing the Combined Work from the
+Application, but excluding the System Libraries of the Combined Work.
+
+  1. Exception to Section 3 of the GNU GPL.
+
+  You may convey a covered work under sections 3 and 4 of this License
+without being bound by section 3 of the GNU GPL.
+
+  2. Conveying Modified Versions.
+
+  If you modify a copy of the Library, and, in your modifications, a
+facility refers to a function or data to be supplied by an Application
+that uses the facility (other than as an argument passed when the
+facility is invoked), then you may convey a copy of the modified
+version:
+
+   a) under this License, provided that you make a good faith effort to
+   ensure that, in the event an Application does not supply the
+   function or data, the facility still operates, and performs
+   whatever part of its purpose remains meaningful, or
+
+   b) under the GNU GPL, with none of the additional permissions of
+   this License applicable to that copy.
+
+  3. Object Code Incorporating Material from Library Header Files.
+
+  The object code form of an Application may incorporate material from
+a header file that is part of the Library.  You may convey such object
+code under terms of your choice, provided that, if the incorporated
+material is not limited to numerical parameters, data structure
+layouts and accessors, or small macros, inline functions and templates
+(ten or fewer lines in length), you do both of the following:
+
+   a) Give prominent notice with each copy of the object code that the
+   Library is used in it and that the Library and its use are
+   covered by this License.
+
+   b) Accompany the object code with a copy of the GNU GPL and this license
+   document.
+
+  4. Combined Works.
+
+  You may convey a Combined Work under terms of your choice that,
+taken together, effectively do not restrict modification of the
+portions of the Library contained in the Combined Work and reverse
+engineering for debugging such modifications, if you also do each of
+the following:
+
+   a) Give prominent notice with each copy of the Combined Work that
+   the Library is used in it and that the Library and its use are
+   covered by this License.
+
+   b) Accompany the Combined Work with a copy of the GNU GPL and this license
+   document.
+
+   c) For a Combined Work that displays copyright notices during
+   execution, include the copyright notice for the Library among
+   these notices, as well as a reference directing the user to the
+   copies of the GNU GPL and this license document.
+
+   d) Do one of the following:
+
+       0) Convey the Minimal Corresponding Source under the terms of this
+       License, and the Corresponding Application Code in a form
+       suitable for, and under terms that permit, the user to
+       recombine or relink the Application with a modified version of
+       the Linked Version to produce a modified Combined Work, in the
+       manner specified by section 6 of the GNU GPL for conveying
+       Corresponding Source.
+
+       1) Use a suitable shared library mechanism for linking with the
+       Library.  A suitable mechanism is one that (a) uses at run time
+       a copy of the Library already present on the user's computer
+       system, and (b) will operate properly with a modified version
+       of the Library that is interface-compatible with the Linked
+       Version.
+
+   e) Provide Installation Information, but only if you would otherwise
+   be required to provide such information under section 6 of the
+   GNU GPL, and only to the extent that such information is
+   necessary to install and execute a modified version of the
+   Combined Work produced by recombining or relinking the
+   Application with a modified version of the Linked Version. (If
+   you use option 4d0, the Installation Information must accompany
+   the Minimal Corresponding Source and Corresponding Application
+   Code. If you use option 4d1, you must provide the Installation
+   Information in the manner specified by section 6 of the GNU GPL
+   for conveying Corresponding Source.)
+
+  5. Combined Libraries.
+
+  You may place library facilities that are a work based on the
+Library side by side in a single library together with other library
+facilities that are not Applications and are not covered by this
+License, and convey such a combined library under terms of your
+choice, if you do both of the following:
+
+   a) Accompany the combined library with a copy of the same work based
+   on the Library, uncombined with any other library facilities,
+   conveyed under the terms of this License.
+
+   b) Give prominent notice with the combined library that part of it
+   is a work based on the Library, and explaining where to find the
+   accompanying uncombined form of the same work.
+
+  6. Revised Versions of the GNU Lesser General Public License.
+
+  The Free Software Foundation may publish revised and/or new versions
+of the GNU Lesser General Public License from time to time. Such new
+versions will be similar in spirit to the present version, but may
+differ in detail to address new problems or concerns.
+
+  Each version is given a distinguishing version number. If the
+Library as you received it specifies that a certain numbered version
+of the GNU Lesser General Public License "or any later version"
+applies to it, you have the option of following the terms and
+conditions either of that published version or of any later version
+published by the Free Software Foundation. If the Library as you
+received it does not specify a version number of the GNU Lesser
+General Public License, you may choose any version of the GNU Lesser
+General Public License ever published by the Free Software Foundation.
+
+  If the Library as you received it specifies that a proxy can decide
+whether future versions of the GNU Lesser General Public License shall
+apply, that proxy's public statement of acceptance of any version is
+permanent authorization for you to choose that version for the
+Library.

+                    GNU GENERAL PUBLIC LICENSE
+                       Version 3, 29 June 2007
+
+ Copyright (C) 2007 Free Software Foundation, Inc. <https://fsf.org/>
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+                            Preamble
+
+  The GNU General Public License is a free, copyleft license for
+software and other kinds of works.
+
+  The licenses for most software and other practical works are designed
+to take away your freedom to share and change the works.  By contrast,
+the GNU General Public License is intended to guarantee your freedom to
+share and change all versions of a program--to make sure it remains free
+software for all its users.  We, the Free Software Foundation, use the
+GNU General Public License for most of our software; it applies also to
+any other work released this way by its authors.  You can apply it to
+your programs, too.
+
+  When we speak of free software, we are referring to freedom, not
+price.  Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+them if you wish), that you receive source code or can get it if you
+want it, that you can change the software or use pieces of it in new
+free programs, and that you know you can do these things.
+
+  To protect your rights, we need to prevent others from denying you
+these rights or asking you to surrender the rights.  Therefore, you have
+certain responsibilities if you distribute copies of the software, or if
+you modify it: responsibilities to respect the freedom of others.
+
+  For example, if you distribute copies of such a program, whether
+gratis or for a fee, you must pass on to the recipients the same
+freedoms that you received.  You must make sure that they, too, receive
+or can get the source code.  And you must show them these terms so they
+know their rights.
+
+  Developers that use the GNU GPL protect your rights with two steps:
+(1) assert copyright on the software, and (2) offer you this License
+giving you legal permission to copy, distribute and/or modify it.
+
+  For the developers' and authors' protection, the GPL clearly explains
+that there is no warranty for this free software.  For both users' and
+authors' sake, the GPL requires that modified versions be marked as
+changed, so that their problems will not be attributed erroneously to
+authors of previous versions.
+
+  Some devices are designed to deny users access to install or run
+modified versions of the software inside them, although the manufacturer
+can do so.  This is fundamentally incompatible with the aim of
+protecting users' freedom to change the software.  The systematic
+pattern of such abuse occurs in the area of products for individuals to
+use, which is precisely where it is most unacceptable.  Therefore, we
+have designed this version of the GPL to prohibit the practice for those
+products.  If such problems arise substantially in other domains, we
+stand ready to extend this provision to those domains in future versions
+of the GPL, as needed to protect the freedom of users.
+
+  Finally, every program is threatened constantly by software patents.
+States should not allow patents to restrict development and use of
+software on general-purpose computers, but in those that do, we wish to
+avoid the special danger that patents applied to a free program could
+make it effectively proprietary.  To prevent this, the GPL assures that
+patents cannot be used to render the program non-free.
+
+  The precise terms and conditions for copying, distribution and
+modification follow.
+
+                       TERMS AND CONDITIONS
+
+  0. Definitions.
+
+  "This License" refers to version 3 of the GNU General Public License.
+
+  "Copyright" also means copyright-like laws that apply to other kinds of
+works, such as semiconductor masks.
+
+  "The Program" refers to any copyrightable work licensed under this
+License.  Each licensee is addressed as "you".  "Licensees" and
+"recipients" may be individuals or organizations.
+
+  To "modify" a work means to copy from or adapt all or part of the work
+in a fashion requiring copyright permission, other than the making of an
+exact copy.  The resulting work is called a "modified version" of the
+earlier work or a work "based on" the earlier work.
+
+  A "covered work" means either the unmodified Program or a work based
+on the Program.
+
+  To "propagate" a work means to do anything with it that, without
+permission, would make you directly or secondarily liable for
+infringement under applicable copyright law, except executing it on a
+computer or modifying a private copy.  Propagation includes copying,
+distribution (with or without modification), making available to the
+public, and in some countries other activities as well.
+
+  To "convey" a work means any kind of propagation that enables other
+parties to make or receive copies.  Mere interaction with a user through
+a computer network, with no transfer of a copy, is not conveying.
+
+  An interactive user interface displays "Appropriate Legal Notices"
+to the extent that it includes a convenient and prominently visible
+feature that (1) displays an appropriate copyright notice, and (2)
+tells the user that there is no warranty for the work (except to the
+extent that warranties are provided), that licensees may convey the
+work under this License, and how to view a copy of this License.  If
+the interface presents a list of user commands or options, such as a
+menu, a prominent item in the list meets this criterion.
+
+  1. Source Code.
+
+  The "source code" for a work means the preferred form of the work
+for making modifications to it.  "Object code" means any non-source
+form of a work.
+
+  A "Standard Interface" means an interface that either is an official
+standard defined by a recognized standards body, or, in the case of
+interfaces specified for a particular programming language, one that
+is widely used among developers working in that language.
+
+  The "System Libraries" of an executable work include anything, other
+than the work as a whole, that (a) is included in the normal form of
+packaging a Major Component, but which is not part of that Major
+Component, and (b) serves only to enable use of the work with that
+Major Component, or to implement a Standard Interface for which an
+implementation is available to the public in source code form.  A
+"Major Component", in this context, means a major essential component
+(kernel, window system, and so on) of the specific operating system
+(if any) on which the executable work runs, or a compiler used to
+produce the work, or an object code interpreter used to run it.
+
+  The "Corresponding Source" for a work in object code form means all
+the source code needed to generate, install, and (for an executable
+work) run the object code and to modify the work, including scripts to
+control those activities.  However, it does not include the work's
+System Libraries, or general-purpose tools or generally available free
+programs which are used unmodified in performing those activities but
+which are not part of the work.  For example, Corresponding Source
+includes interface definition files associated with source files for
+the work, and the source code for shared libraries and dynamically
+linked subprograms that the work is specifically designed to require,
+such as by intimate data communication or control flow between those
+subprograms and other parts of the work.
+
+  The Corresponding Source need not include anything that users
+can regenerate automatically from other parts of the Corresponding
+Source.
+
+  The Corresponding Source for a work in source code form is that
+same work.
+
+  2. Basic Permissions.
+
+  All rights granted under this License are granted for the term of
+copyright on the Program, and are irrevocable provided the stated
+conditions are met.  This License explicitly affirms your unlimited
+permission to run the unmodified Program.  The output from running a
+covered work is covered by this License only if the output, given its
+content, constitutes a covered work.  This License acknowledges your
+rights of fair use or other equivalent, as provided by copyright law.
+
+  You may make, run and propagate covered works that you do not
+convey, without conditions so long as your license otherwise remains
+in force.  You may convey covered works to others for the sole purpose
+of having them make modifications exclusively for you, or provide you
+with facilities for running those works, provided that you comply with
+the terms of this License in conveying all material for which you do
+not control copyright.  Those thus making or running the covered works
+for you must do so exclusively on your behalf, under your direction
+and control, on terms that prohibit them from making any copies of
+your copyrighted material outside their relationship with you.
+
+  Conveying under any other circumstances is permitted solely under
+the conditions stated below.  Sublicensing is not allowed; section 10
+makes it unnecessary.
+
+  3. Protecting Users' Legal Rights From Anti-Circumvention Law.
+
+  No covered work shall be deemed part of an effective technological
+measure under any applicable law fulfilling obligations under article
+11 of the WIPO copyright treaty adopted on 20 December 1996, or
+similar laws prohibiting or restricting circumvention of such
+measures.
+
+  When you convey a covered work, you waive any legal power to forbid
+circumvention of technological measures to the extent such circumvention
+is effected by exercising rights under this License with respect to
+the covered work, and you disclaim any intention to limit operation or
+modification of the work as a means of enforcing, against the work's
+users, your or third parties' legal rights to forbid circumvention of
+technological measures.
+
+  4. Conveying Verbatim Copies.
+
+  You may convey verbatim copies of the Program's source code as you
+receive it, in any medium, provided that you conspicuously and
+appropriately publish on each copy an appropriate copyright notice;
+keep intact all notices stating that this License and any
+non-permissive terms added in accord with section 7 apply to the code;
+keep intact all notices of the absence of any warranty; and give all
+recipients a copy of this License along with the Program.
+
+  You may charge any price or no price for each copy that you convey,
+and you may offer support or warranty protection for a fee.
+
+  5. Conveying Modified Source Versions.
+
+  You may convey a work based on the Program, or the modifications to
+produce it from the Program, in the form of source code under the
+terms of section 4, provided that you also meet all of these conditions:
+
+    a) The work must carry prominent notices stating that you modified
+    it, and giving a relevant date.
+
+    b) The work must carry prominent notices stating that it is
+    released under this License and any conditions added under section
+    7.  This requirement modifies the requirement in section 4 to
+    "keep intact all notices".
+
+    c) You must license the entire work, as a whole, under this
+    License to anyone who comes into possession of a copy.  This
+    License will therefore apply, along with any applicable section 7
+    additional terms, to the whole of the work, and all its parts,
+    regardless of how they are packaged.  This License gives no
+    permission to license the work in any other way, but it does not
+    invalidate such permission if you have separately received it.
+
+    d) If the work has interactive user interfaces, each must display
+    Appropriate Legal Notices; however, if the Program has interactive
+    interfaces that do not display Appropriate Legal Notices, your
+    work need not make them do so.
+
+  A compilation of a covered work with other separate and independent
+works, which are not by their nature extensions of the covered work,
+and which are not combined with it such as to form a larger program,
+in or on a volume of a storage or distribution medium, is called an
+"aggregate" if the compilation and its resulting copyright are not
+used to limit the access or legal rights of the compilation's users
+beyond what the individual works permit.  Inclusion of a covered work
+in an aggregate does not cause this License to apply to the other
+parts of the aggregate.
+
+  6. Conveying Non-Source Forms.
+
+  You may convey a covered work in object code form under the terms
+of sections 4 and 5, provided that you also convey the
+machine-readable Corresponding Source under the terms of this License,
+in one of these ways:
+
+    a) Convey the object code in, or embodied in, a physical product
+    (including a physical distribution medium), accompanied by the
+    Corresponding Source fixed on a durable physical medium
+    customarily used for software interchange.
+
+    b) Convey the object code in, or embodied in, a physical product
+    (including a physical distribution medium), accompanied by a
+    written offer, valid for at least three years and valid for as
+    long as you offer spare parts or customer support for that product
+    model, to give anyone who possesses the object code either (1) a
+    copy of the Corresponding Source for all the software in the
+    product that is covered by this License, on a durable physical
+    medium customarily used for software interchange, for a price no
+    more than your reasonable cost of physically performing this
+    conveying of source, or (2) access to copy the
+    Corresponding Source from a network server at no charge.
+
+    c) Convey individual copies of the object code with a copy of the
+    written offer to provide the Corresponding Source.  This
+    alternative is allowed only occasionally and noncommercially, and
+    only if you received the object code with such an offer, in accord
+    with subsection 6b.
+
+    d) Convey the object code by offering access from a designated
+    place (gratis or for a charge), and offer equivalent access to the
+    Corresponding Source in the same way through the same place at no
+    further charge.  You need not require recipients to copy the
+    Corresponding Source along with the object code.  If the place to
+    copy the object code is a network server, the Corresponding Source
+    may be on a different server (operated by you or a third party)
+    that supports equivalent copying facilities, provided you maintain
+    clear directions next to the object code saying where to find the
+    Corresponding Source.  Regardless of what server hosts the
+    Corresponding Source, you remain obligated to ensure that it is
+    available for as long as needed to satisfy these requirements.
+
+    e) Convey the object code using peer-to-peer transmission, provided
+    you inform other peers where the object code and Corresponding
+    Source of the work are being offered to the general public at no
+    charge under subsection 6d.
+
+  A separable portion of the object code, whose source code is excluded
+from the Corresponding Source as a System Library, need not be
+included in conveying the object code work.
+
+  A "User Product" is either (1) a "consumer product", which means any
+tangible personal property which is normally used for personal, family,
+or household purposes, or (2) anything designed or sold for incorporation
+into a dwelling.  In determining whether a product is a consumer product,
+doubtful cases shall be resolved in favor of coverage.  For a particular
+product received by a particular user, "normally used" refers to a
+typical or common use of that class of product, regardless of the status
+of the particular user or of the way in which the particular user
+actually uses, or expects or is expected to use, the product.  A product
+is a consumer product regardless of whether the product has substantial
+commercial, industrial or non-consumer uses, unless such uses represent
+the only significant mode of use of the product.
+
+  "Installation Information" for a User Product means any methods,
+procedures, authorization keys, or other information required to install
+and execute modified versions of a covered work in that User Product from
+a modified version of its Corresponding Source.  The information must
+suffice to ensure that the continued functioning of the modified object
+code is in no case prevented or interfered with solely because
+modification has been made.
+
+  If you convey an object code work under this section in, or with, or
+specifically for use in, a User Product, and the conveying occurs as
+part of a transaction in which the right of possession and use of the
+User Product is transferred to the recipient in perpetuity or for a
+fixed term (regardless of how the transaction is characterized), the
+Corresponding Source conveyed under this section must be accompanied
+by the Installation Information.  But this requirement does not apply
+if neither you nor any third party retains the ability to install
+modified object code on the User Product (for example, the work has
+been installed in ROM).
+
+  The requirement to provide Installation Information does not include a
+requirement to continue to provide support service, warranty, or updates
+for a work that has been modified or installed by the recipient, or for
+the User Product in which it has been modified or installed.  Access to a
+network may be denied when the modification itself materially and
+adversely affects the operation of the network or violates the rules and
+protocols for communication across the network.
+
+  Corresponding Source conveyed, and Installation Information provided,
+in accord with this section must be in a format that is publicly
+documented (and with an implementation available to the public in
+source code form), and must require no special password or key for
+unpacking, reading or copying.
+
+  7. Additional Terms.
+
+  "Additional permissions" are terms that supplement the terms of this
+License by making exceptions from one or more of its conditions.
+Additional permissions that are applicable to the entire Program shall
+be treated as though they were included in this License, to the extent
+that they are valid under applicable law.  If additional permissions
+apply only to part of the Program, that part may be used separately
+under those permissions, but the entire Program remains governed by
+this License without regard to the additional permissions.
+
+  When you convey a copy of a covered work, you may at your option
+remove any additional permissions from that copy, or from any part of
+it.  (Additional permissions may be written to require their own
+removal in certain cases when you modify the work.)  You may place
+additional permissions on material, added by you to a covered work,
+for which you have or can give appropriate copyright permission.
+
+  Notwithstanding any other provision of this License, for material you
+add to a covered work, you may (if authorized by the copyright holders of
+that material) supplement the terms of this License with terms:
+
+    a) Disclaiming warranty or limiting liability differently from the
+    terms of sections 15 and 16 of this License; or
+
+    b) Requiring preservation of specified reasonable legal notices or
+    author attributions in that material or in the Appropriate Legal
+    Notices displayed by works containing it; or
+
+    c) Prohibiting misrepresentation of the origin of that material, or
+    requiring that modified versions of such material be marked in
+    reasonable ways as different from the original version; or
+
+    d) Limiting the use for publicity purposes of names of licensors or
+    authors of the material; or
+
+    e) Declining to grant rights under trademark law for use of some
+    trade names, trademarks, or service marks; or
+
+    f) Requiring indemnification of licensors and authors of that
+    material by anyone who conveys the material (or modified versions of
+    it) with contractual assumptions of liability to the recipient, for
+    any liability that these contractual assumptions directly impose on
+    those licensors and authors.
+
+  All other non-permissive additional terms are considered "further
+restrictions" within the meaning of section 10.  If the Program as you
+received it, or any part of it, contains a notice stating that it is
+governed by this License along with a term that is a further
+restriction, you may remove that term.  If a license document contains
+a further restriction but permits relicensing or conveying under this
+License, you may add to a covered work material governed by the terms
+of that license document, provided that the further restriction does
+not survive such relicensing or conveying.
+
+  If you add terms to a covered work in accord with this section, you
+must place, in the relevant source files, a statement of the
+additional terms that apply to those files, or a notice indicating
+where to find the applicable terms.
+
+  Additional terms, permissive or non-permissive, may be stated in the
+form of a separately written license, or stated as exceptions;
+the above requirements apply either way.
+
+  8. Termination.
+
+  You may not propagate or modify a covered work except as expressly
+provided under this License.  Any attempt otherwise to propagate or
+modify it is void, and will automatically terminate your rights under
+this License (including any patent licenses granted under the third
+paragraph of section 11).
+
+  However, if you cease all violation of this License, then your
+license from a particular copyright holder is reinstated (a)
+provisionally, unless and until the copyright holder explicitly and
+finally terminates your license, and (b) permanently, if the copyright
+holder fails to notify you of the violation by some reasonable means
+prior to 60 days after the cessation.
+
+  Moreover, your license from a particular copyright holder is
+reinstated permanently if the copyright holder notifies you of the
+violation by some reasonable means, this is the first time you have
+received notice of violation of this License (for any work) from that
+copyright holder, and you cure the violation prior to 30 days after
+your receipt of the notice.
+
+  Termination of your rights under this section does not terminate the
+licenses of parties who have received copies or rights from you under
+this License.  If your rights have been terminated and not permanently
+reinstated, you do not qualify to receive new licenses for the same
+material under section 10.
+
+  9. Acceptance Not Required for Having Copies.
+
+  You are not required to accept this License in order to receive or
+run a copy of the Program.  Ancillary propagation of a covered work
+occurring solely as a consequence of using peer-to-peer transmission
+to receive a copy likewise does not require acceptance.  However,
+nothing other than this License grants you permission to propagate or
+modify any covered work.  These actions infringe copyright if you do
+not accept this License.  Therefore, by modifying or propagating a
+covered work, you indicate your acceptance of this License to do so.
+
+  10. Automatic Licensing of Downstream Recipients.
+
+  Each time you convey a covered work, the recipient automatically
+receives a license from the original licensors, to run, modify and
+propagate that work, subject to this License.  You are not responsible
+for enforcing compliance by third parties with this License.
+
+  An "entity transaction" is a transaction transferring control of an
+organization, or substantially all assets of one, or subdividing an
+organization, or merging organizations.  If propagation of a covered
+work results from an entity transaction, each party to that
+transaction who receives a copy of the work also receives whatever
+licenses to the work the party's predecessor in interest had or could
+give under the previous paragraph, plus a right to possession of the
+Corresponding Source of the work from the predecessor in interest, if
+the predecessor has it or can get it with reasonable efforts.
+
+  You may not impose any further restrictions on the exercise of the
+rights granted or affirmed under this License.  For example, you may
+not impose a license fee, royalty, or other charge for exercise of
+rights granted under this License, and you may not initiate litigation
+(including a cross-claim or counterclaim in a lawsuit) alleging that
+any patent claim is infringed by making, using, selling, offering for
+sale, or importing the Program or any portion of it.
+
+  11. Patents.
+
+  A "contributor" is a copyright holder who authorizes use under this
+License of the Program or a work on which the Program is based.  The
+work thus licensed is called the contributor's "contributor version".
+
+  A contributor's "essential patent claims" are all patent claims
+owned or controlled by the contributor, whether already acquired or
+hereafter acquired, that would be infringed by some manner, permitted
+by this License, of making, using, or selling its contributor version,
+but do not include claims that would be infringed only as a
+consequence of further modification of the contributor version.  For
+purposes of this definition, "control" includes the right to grant
+patent sublicenses in a manner consistent with the requirements of
+this License.
+
+  Each contributor grants you a non-exclusive, worldwide, royalty-free
+patent license under the contributor's essential patent claims, to
+make, use, sell, offer for sale, import and otherwise run, modify and
+propagate the contents of its contributor version.
+
+  In the following three paragraphs, a "patent license" is any express
+agreement or commitment, however denominated, not to enforce a patent
+(such as an express permission to practice a patent or covenant not to
+sue for patent infringement).  To "grant" such a patent license to a
+party means to make such an agreement or commitment not to enforce a
+patent against the party.
+
+  If you convey a covered work, knowingly relying on a patent license,
+and the Corresponding Source of the work is not available for anyone
+to copy, free of charge and under the terms of this License, through a
+publicly available network server or other readily accessible means,
+then you must either (1) cause the Corresponding Source to be so
+available, or (2) arrange to deprive yourself of the benefit of the
+patent license for this particular work, or (3) arrange, in a manner
+consistent with the requirements of this License, to extend the patent
+license to downstream recipients.  "Knowingly relying" means you have
+actual knowledge that, but for the patent license, your conveying the
+covered work in a country, or your recipient's use of the covered work
+in a country, would infringe one or more identifiable patents in that
+country that you have reason to believe are valid.
+
+  If, pursuant to or in connection with a single transaction or
+arrangement, you convey, or propagate by procuring conveyance of, a
+covered work, and grant a patent license to some of the parties
+receiving the covered work authorizing them to use, propagate, modify
+or convey a specific copy of the covered work, then the patent license
+you grant is automatically extended to all recipients of the covered
+work and works based on it.
+
+  A patent license is "discriminatory" if it does not include within
+the scope of its coverage, prohibits the exercise of, or is
+conditioned on the non-exercise of one or more of the rights that are
+specifically granted under this License.  You may not convey a covered
+work if you are a party to an arrangement with a third party that is
+in the business of distributing software, under which you make payment
+to the third party based on the extent of your activity of conveying
+the work, and under which the third party grants, to any of the
+parties who would receive the covered work from you, a discriminatory
+patent license (a) in connection with copies of the covered work
+conveyed by you (or copies made from those copies), or (b) primarily
+for and in connection with specific products or compilations that
+contain the covered work, unless you entered into that arrangement,
+or that patent license was granted, prior to 28 March 2007.
+
+  Nothing in this License shall be construed as excluding or limiting
+any implied license or other defenses to infringement that may
+otherwise be available to you under applicable patent law.
+
+  12. No Surrender of Others' Freedom.
+
+  If conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License.  If you cannot convey a
+covered work so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you may
+not convey it at all.  For example, if you agree to terms that obligate you
+to collect a royalty for further conveying from those to whom you convey
+the Program, the only way you could satisfy both those terms and this
+License would be to refrain entirely from conveying the Program.
+
+  13. Use with the GNU Affero General Public License.
+
+  Notwithstanding any other provision of this License, you have
+permission to link or combine any covered work with a work licensed
+under version 3 of the GNU Affero General Public License into a single
+combined work, and to convey the resulting work.  The terms of this
+License will continue to apply to the part which is the covered work,
+but the special requirements of the GNU Affero General Public License,
+section 13, concerning interaction through a network will apply to the
+combination as such.
+
+  14. Revised Versions of this License.
+
+  The Free Software Foundation may publish revised and/or new versions of
+the GNU General Public License from time to time.  Such new versions will
+be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.
+
+  Each version is given a distinguishing version number.  If the
+Program specifies that a certain numbered version of the GNU General
+Public License "or any later version" applies to it, you have the
+option of following the terms and conditions either of that numbered
+version or of any later version published by the Free Software
+Foundation.  If the Program does not specify a version number of the
+GNU General Public License, you may choose any version ever published
+by the Free Software Foundation.
+
+  If the Program specifies that a proxy can decide which future
+versions of the GNU General Public License can be used, that proxy's
+public statement of acceptance of a version permanently authorizes you
+to choose that version for the Program.
+
+  Later license versions may give you additional or different
+permissions.  However, no additional obligations are imposed on any
+author or copyright holder as a result of your choosing to follow a
+later version.
+
+  15. Disclaimer of Warranty.
+
+  THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
+APPLICABLE LAW.  EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
+HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY
+OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
+THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
+PURPOSE.  THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM
+IS WITH YOU.  SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
+ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
+
+  16. Limitation of Liability.
+
+  IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
+THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
+GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE
+USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF
+DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
+PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),
+EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF
+SUCH DAMAGES.
+
+  17. Interpretation of Sections 15 and 16.
+
+  If the disclaimer of warranty and limitation of liability provided
+above cannot be given local legal effect according to their terms,
+reviewing courts shall apply local law that most closely approximates
+an absolute waiver of all civil liability in connection with the
+Program, unless a warranty or assumption of liability accompanies a
+copy of the Program in return for a fee.
+
+                     END OF TERMS AND CONDITIONS

+                       Version 3, 29 June 2007
+
+ Copyright (C) 2007 Free Software Foundation, Inc. <https://fsf.org/>
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+
+  This version of the GNU Lesser General Public License incorporates
+the terms and conditions of version 3 of the GNU General Public
+License, supplemented by the additional permissions listed below.
+
+  0. Additional Definitions.
+
+  As used herein, "this License" refers to version 3 of the GNU Lesser
+General Public License, and the "GNU GPL" refers to version 3 of the GNU
+General Public License.
+
+  "The Library" refers to a covered work governed by this License,
+other than an Application or a Combined Work as defined below.
+
+  An "Application" is any work that makes use of an interface provided
+by the Library, but which is not otherwise based on the Library.
+Defining a subclass of a class defined by the Library is deemed a mode
+of using an interface provided by the Library.
+
+  A "Combined Work" is a work produced by combining or linking an
+Application with the Library.  The particular version of the Library
+with which the Combined Work was made is also called the "Linked
+Version".
+
+  The "Minimal Corresponding Source" for a Combined Work means the
+Corresponding Source for the Combined Work, excluding any source code
+for portions of the Combined Work that, considered in isolation, are
+based on the Application, and not on the Linked Version.
+
+  The "Corresponding Application Code" for a Combined Work means the
+object code and/or source code for the Application, including any data
+and utility programs needed for reproducing the Combined Work from the
+Application, but excluding the System Libraries of the Combined Work.
+
+  1. Exception to Section 3 of the GNU GPL.
+
+  You may convey a covered work under sections 3 and 4 of this License
+without being bound by section 3 of the GNU GPL.
+
+  2. Conveying Modified Versions.
+
+  If you modify a copy of the Library, and, in your modifications, a
+facility refers to a function or data to be supplied by an Application
+that uses the facility (other than as an argument passed when the
+facility is invoked), then you may convey a copy of the modified
+version:
+
+   a) under this License, provided that you make a good faith effort to
+   ensure that, in the event an Application does not supply the
+   function or data, the facility still operates, and performs
+   whatever part of its purpose remains meaningful, or
+
+   b) under the GNU GPL, with none of the additional permissions of
+   this License applicable to that copy.
+
+  3. Object Code Incorporating Material from Library Header Files.
+
+  The object code form of an Application may incorporate material from
+a header file that is part of the Library.  You may convey such object
+code under terms of your choice, provided that, if the incorporated
+material is not limited to numerical parameters, data structure
+layouts and accessors, or small macros, inline functions and templates
+(ten or fewer lines in length), you do both of the following:
+
+   a) Give prominent notice with each copy of the object code that the
+   Library is used in it and that the Library and its use are
+   covered by this License.
+
+   b) Accompany the object code with a copy of the GNU GPL and this license
+   document.
+
+  4. Combined Works.
+
+  You may convey a Combined Work under terms of your choice that,
+taken together, effectively do not restrict modification of the
+portions of the Library contained in the Combined Work and reverse
+engineering for debugging such modifications, if you also do each of
+the following:
+
+   a) Give prominent notice with each copy of the Combined Work that
+   the Library is used in it and that the Library and its use are
+   covered by this License.
+
+   b) Accompany the Combined Work with a copy of the GNU GPL and this license
+   document.
+
+   c) For a Combined Work that displays copyright notices during
+   execution, include the copyright notice for the Library among
+   these notices, as well as a reference directing the user to the
+   copies of the GNU GPL and this license document.
+
+   d) Do one of the following:
+
+       0) Convey the Minimal Corresponding Source under the terms of this
+       License, and the Corresponding Application Code in a form
+       suitable for, and under terms that permit, the user to
+       recombine or relink the Application with a modified version of
+       the Linked Version to produce a modified Combined Work, in the
+       manner specified by section 6 of the GNU GPL for conveying
+       Corresponding Source.
+
+       1) Use a suitable shared library mechanism for linking with the
+       Library.  A suitable mechanism is one that (a) uses at run time
+       a copy of the Library already present on the user's computer
+       system, and (b) will operate properly with a modified version
+       of the Library that is interface-compatible with the Linked
+       Version.
+
+   e) Provide Installation Information, but only if you would otherwise
+   be required to provide such information under section 6 of the
+   GNU GPL, and only to the extent that such information is
+   necessary to install and execute a modified version of the
+   Combined Work produced by recombining or relinking the
+   Application with a modified version of the Linked Version. (If
+   you use option 4d0, the Installation Information must accompany
+   the Minimal Corresponding Source and Corresponding Application
+   Code. If you use option 4d1, you must provide the Installation
+   Information in the manner specified by section 6 of the GNU GPL
+   for conveying Corresponding Source.)
+
+  5. Combined Libraries.
+
+  You may place library facilities that are a work based on the
+Library side by side in a single library together with other library
+facilities that are not Applications and are not covered by this
+License, and convey such a combined library under terms of your
+choice, if you do both of the following:
+
+   a) Accompany the combined library with a copy of the same work based
+   on the Library, uncombined with any other library facilities,
+   conveyed under the terms of this License.
+
+   b) Give prominent notice with the combined library that part of it
+   is a work based on the Library, and explaining where to find the
+   accompanying uncombined form of the same work.
+
+  6. Revised Versions of the GNU Lesser General Public License.
+
+  The Free Software Foundation may publish revised and/or new versions
+of the GNU Lesser General Public License from time to time. Such new
+versions will be similar in spirit to the present version, but may
+differ in detail to address new problems or concerns.
+
+  Each version is given a distinguishing version number. If the
+Library as you received it specifies that a certain numbered version
+of the GNU Lesser General Public License "or any later version"
+applies to it, you have the option of following the terms and
+conditions either of that published version or of any later version
+published by the Free Software Foundation. If the Library as you
+received it does not specify a version number of the GNU Lesser
+General Public License, you may choose any version of the GNU Lesser
+General Public License ever published by the Free Software Foundation.
+
+  If the Library as you received it specifies that a proxy can decide
+whether future versions of the GNU Lesser General Public License shall
+apply, that proxy's public statement of acceptance of any version is
+permanent authorization for you to choose that version for the
+Library.

+                    GNU GENERAL PUBLIC LICENSE
+                       Version 3, 29 June 2007
+
+ Copyright (C) 2007 Free Software Foundation, Inc. <https://fsf.org/>
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+                            Preamble
+
+  The GNU General Public License is a free, copyleft license for
+software and other kinds of works.
+
+  The licenses for most software and other practical works are designed
+to take away your freedom to share and change the works.  By contrast,
+the GNU General Public License is intended to guarantee your freedom to
+share and change all versions of a program--to make sure it remains free
+software for all its users.  We, the Free Software Foundation, use the
+GNU General Public License for most of our software; it applies also to
+any other work released this way by its authors.  You can apply it to
+your programs, too.
+
+  When we speak of free software, we are referring to freedom, not
+price.  Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+them if you wish), that you receive source code or can get it if you
+want it, that you can change the software or use pieces of it in new
+free programs, and that you know you can do these things.
+
+  To protect your rights, we need to prevent others from denying you
+these rights or asking you to surrender the rights.  Therefore, you have
+certain responsibilities if you distribute copies of the software, or if
+you modify it: responsibilities to respect the freedom of others.
+
+  For example, if you distribute copies of such a program, whether
+gratis or for a fee, you must pass on to the recipients the same
+freedoms that you received.  You must make sure that they, too, receive
+or can get the source code.  And you must show them these terms so they
+know their rights.
+
+  Developers that use the GNU GPL protect your rights with two steps:
+(1) assert copyright on the software, and (2) offer you this License
+giving you legal permission to copy, distribute and/or modify it.
+
+  For the developers' and authors' protection, the GPL clearly explains
+that there is no warranty for this free software.  For both users' and
+authors' sake, the GPL requires that modified versions be marked as
+changed, so that their problems will not be attributed erroneously to
+authors of previous versions.
+
+  Some devices are designed to deny users access to install or run
+modified versions of the software inside them, although the manufacturer
+can do so.  This is fundamentally incompatible with the aim of
+protecting users' freedom to change the software.  The systematic
+pattern of such abuse occurs in the area of products for individuals to
+use, which is precisely where it is most unacceptable.  Therefore, we
+have designed this version of the GPL to prohibit the practice for those
+products.  If such problems arise substantially in other domains, we
+stand ready to extend this provision to those domains in future versions
+of the GPL, as needed to protect the freedom of users.
+
+  Finally, every program is threatened constantly by software patents.
+States should not allow patents to restrict development and use of
+software on general-purpose computers, but in those that do, we wish to
+avoid the special danger that patents applied to a free program could
+make it effectively proprietary.  To prevent this, the GPL assures that
+patents cannot be used to render the program non-free.
+
+  The precise terms and conditions for copying, distribution and
+modification follow.
+
+                       TERMS AND CONDITIONS
+
+  0. Definitions.
+
+  "This License" refers to version 3 of the GNU General Public License.
+
+  "Copyright" also means copyright-like laws that apply to other kinds of
+works, such as semiconductor masks.
+
+  "The Program" refers to any copyrightable work licensed under this
+License.  Each licensee is addressed as "you".  "Licensees" and
+"recipients" may be individuals or organizations.
+
+  To "modify" a work means to copy from or adapt all or part of the work
+in a fashion requiring copyright permission, other than the making of an
+exact copy.  The resulting work is called a "modified version" of the
+earlier work or a work "based on" the earlier work.
+
+  A "covered work" means either the unmodified Program or a work based
+on the Program.
+
+  To "propagate" a work means to do anything with it that, without
+permission, would make you directly or secondarily liable for
+infringement under applicable copyright law, except executing it on a
+computer or modifying a private copy.  Propagation includes copying,
+distribution (with or without modification), making available to the
+public, and in some countries other activities as well.
+
+  To "convey" a work means any kind of propagation that enables other
+parties to make or receive copies.  Mere interaction with a user through
+a computer network, with no transfer of a copy, is not conveying.
+
+  An interactive user interface displays "Appropriate Legal Notices"
+to the extent that it includes a convenient and prominently visible
+feature that (1) displays an appropriate copyright notice, and (2)
+tells the user that there is no warranty for the work (except to the
+extent that warranties are provided), that licensees may convey the
+work under this License, and how to view a copy of this License.  If
+the interface presents a list of user commands or options, such as a
+menu, a prominent item in the list meets this criterion.
+
+  1. Source Code.
+
+  The "source code" for a work means the preferred form of the work
+for making modifications to it.  "Object code" means any non-source
+form of a work.
+
+  A "Standard Interface" means an interface that either is an official
+standard defined by a recognized standards body, or, in the case of
+interfaces specified for a particular programming language, one that
+is widely used among developers working in that language.
+
+  The "System Libraries" of an executable work include anything, other
+than the work as a whole, that (a) is included in the normal form of
+packaging a Major Component, but which is not part of that Major
+Component, and (b) serves only to enable use of the work with that
+Major Component, or to implement a Standard Interface for which an
+implementation is available to the public in source code form.  A
+"Major Component", in this context, means a major essential component
+(kernel, window system, and so on) of the specific operating system
+(if any) on which the executable work runs, or a compiler used to
+produce the work, or an object code interpreter used to run it.
+
+  The "Corresponding Source" for a work in object code form means all
+the source code needed to generate, install, and (for an executable
+work) run the object code and to modify the work, including scripts to
+control those activities.  However, it does not include the work's
+System Libraries, or general-purpose tools or generally available free
+programs which are used unmodified in performing those activities but
+which are not part of the work.  For example, Corresponding Source
+includes interface definition files associated with source files for
+the work, and the source code for shared libraries and dynamically
+linked subprograms that the work is specifically designed to require,
+such as by intimate data communication or control flow between those
+subprograms and other parts of the work.
+
+  The Corresponding Source need not include anything that users
+can regenerate automatically from other parts of the Corresponding
+Source.
+
+  The Corresponding Source for a work in source code form is that
+same work.
+
+  2. Basic Permissions.
+
+  All rights granted under this License are granted for the term of
+copyright on the Program, and are irrevocable provided the stated
+conditions are met.  This License explicitly affirms your unlimited
+permission to run the unmodified Program.  The output from running a
+covered work is covered by this License only if the output, given its
+content, constitutes a covered work.  This License acknowledges your
+rights of fair use or other equivalent, as provided by copyright law.
+
+  You may make, run and propagate covered works that you do not
+convey, without conditions so long as your license otherwise remains
+in force.  You may convey covered works to others for the sole purpose
+of having them make modifications exclusively for you, or provide you
+with facilities for running those works, provided that you comply with
+the terms of this License in conveying all material for which you do
+not control copyright.  Those thus making or running the covered works
+for you must do so exclusively on your behalf, under your direction
+and control, on terms that prohibit them from making any copies of
+your copyrighted material outside their relationship with you.
+
+  Conveying under any other circumstances is permitted solely under
+the conditions stated below.  Sublicensing is not allowed; section 10
+makes it unnecessary.
+
+  3. Protecting Users' Legal Rights From Anti-Circumvention Law.
+
+  No covered work shall be deemed part of an effective technological
+measure under any applicable law fulfilling obligations under article
+11 of the WIPO copyright treaty adopted on 20 December 1996, or
+similar laws prohibiting or restricting circumvention of such
+measures.
+
+  When you convey a covered work, you waive any legal power to forbid
+circumvention of technological measures to the extent such circumvention
+is effected by exercising rights under this License with respect to
+the covered work, and you disclaim any intention to limit operation or
+modification of the work as a means of enforcing, against the work's
+users, your or third parties' legal rights to forbid circumvention of
+technological measures.
+
+  4. Conveying Verbatim Copies.
+
+  You may convey verbatim copies of the Program's source code as you
+receive it, in any medium, provided that you conspicuously and
+appropriately publish on each copy an appropriate copyright notice;
+keep intact all notices stating that this License and any
+non-permissive terms added in accord with section 7 apply to the code;
+keep intact all notices of the absence of any warranty; and give all
+recipients a copy of this License along with the Program.
+
+  You may charge any price or no price for each copy that you convey,
+and you may offer support or warranty protection for a fee.
+
+  5. Conveying Modified Source Versions.
+
+  You may convey a work based on the Program, or the modifications to
+produce it from the Program, in the form of source code under the
+terms of section 4, provided that you also meet all of these conditions:
+
+    a) The work must carry prominent notices stating that you modified
+    it, and giving a relevant date.
+
+    b) The work must carry prominent notices stating that it is
+    released under this License and any conditions added under section
+    7.  This requirement modifies the requirement in section 4 to
+    "keep intact all notices".
+
+    c) You must license the entire work, as a whole, under this
+    License to anyone who comes into possession of a copy.  This
+    License will therefore apply, along with any applicable section 7
+    additional terms, to the whole of the work, and all its parts,
+    regardless of how they are packaged.  This License gives no
+    permission to license the work in any other way, but it does not
+    invalidate such permission if you have separately received it.
+
+    d) If the work has interactive user interfaces, each must display
+    Appropriate Legal Notices; however, if the Program has interactive
+    interfaces that do not display Appropriate Legal Notices, your
+    work need not make them do so.
+
+  A compilation of a covered work with other separate and independent
+works, which are not by their nature extensions of the covered work,
+and which are not combined with it such as to form a larger program,
+in or on a volume of a storage or distribution medium, is called an
+"aggregate" if the compilation and its resulting copyright are not
+used to limit the access or legal rights of the compilation's users
+beyond what the individual works permit.  Inclusion of a covered work
+in an aggregate does not cause this License to apply to the other
+parts of the aggregate.
+
+  6. Conveying Non-Source Forms.
+
+  You may convey a covered work in object code form under the terms
+of sections 4 and 5, provided that you also convey the
+machine-readable Corresponding Source under the terms of this License,
+in one of these ways:
+
+    a) Convey the object code in, or embodied in, a physical product
+    (including a physical distribution medium), accompanied by the
+    Corresponding Source fixed on a durable physical medium
+    customarily used for software interchange.
+
+    b) Convey the object code in, or embodied in, a physical product
+    (including a physical distribution medium), accompanied by a
+    written offer, valid for at least three years and valid for as
+    long as you offer spare parts or customer support for that product
+    model, to give anyone who possesses the object code either (1) a
+    copy of the Corresponding Source for all the software in the
+    product that is covered by this License, on a durable physical
+    medium customarily used for software interchange, for a price no
+    more than your reasonable cost of physically performing this
+    conveying of source, or (2) access to copy the
+    Corresponding Source from a network server at no charge.
+
+    c) Convey individual copies of the object code with a copy of the
+    written offer to provide the Corresponding Source.  This
+    alternative is allowed only occasionally and noncommercially, and
+    only if you received the object code with such an offer, in accord
+    with subsection 6b.
+
+    d) Convey the object code by offering access from a designated
+    place (gratis or for a charge), and offer equivalent access to the
+    Corresponding Source in the same way through the same place at no
+    further charge.  You need not require recipients to copy the
+    Corresponding Source along with the object code.  If the place to
+    copy the object code is a network server, the Corresponding Source
+    may be on a different server (operated by you or a third party)
+    that supports equivalent copying facilities, provided you maintain
+    clear directions next to the object code saying where to find the
+    Corresponding Source.  Regardless of what server hosts the
+    Corresponding Source, you remain obligated to ensure that it is
+    available for as long as needed to satisfy these requirements.
+
+    e) Convey the object code using peer-to-peer transmission, provided
+    you inform other peers where the object code and Corresponding
+    Source of the work are being offered to the general public at no
+    charge under subsection 6d.
+
+  A separable portion of the object code, whose source code is excluded
+from the Corresponding Source as a System Library, need not be
+included in conveying the object code work.
+
+  A "User Product" is either (1) a "consumer product", which means any
+tangible personal property which is normally used for personal, family,
+or household purposes, or (2) anything designed or sold for incorporation
+into a dwelling.  In determining whether a product is a consumer product,
+doubtful cases shall be resolved in favor of coverage.  For a particular
+product received by a particular user, "normally used" refers to a
+typical or common use of that class of product, regardless of the status
+of the particular user or of the way in which the particular user
+actually uses, or expects or is expected to use, the product.  A product
+is a consumer product regardless of whether the product has substantial
+commercial, industrial or non-consumer uses, unless such uses represent
+the only significant mode of use of the product.
+
+  "Installation Information" for a User Product means any methods,
+procedures, authorization keys, or other information required to install
+and execute modified versions of a covered work in that User Product from
+a modified version of its Corresponding Source.  The information must
+suffice to ensure that the continued functioning of the modified object
+code is in no case prevented or interfered with solely because
+modification has been made.
+
+  If you convey an object code work under this section in, or with, or
+specifically for use in, a User Product, and the conveying occurs as
+part of a transaction in which the right of possession and use of the
+User Product is transferred to the recipient in perpetuity or for a
+fixed term (regardless of how the transaction is characterized), the
+Corresponding Source conveyed under this section must be accompanied
+by the Installation Information.  But this requirement does not apply
+if neither you nor any third party retains the ability to install
+modified object code on the User Product (for example, the work has
+been installed in ROM).
+
+  The requirement to provide Installation Information does not include a
+requirement to continue to provide support service, warranty, or updates
+for a work that has been modified or installed by the recipient, or for
+the User Product in which it has been modified or installed.  Access to a
+network may be denied when the modification itself materially and
+adversely affects the operation of the network or violates the rules and
+protocols for communication across the network.
+
+  Corresponding Source conveyed, and Installation Information provided,
+in accord with this section must be in a format that is publicly
+documented (and with an implementation available to the public in
+source code form), and must require no special password or key for
+unpacking, reading or copying.
+
+  7. Additional Terms.
+
+  "Additional permissions" are terms that supplement the terms of this
+License by making exceptions from one or more of its conditions.
+Additional permissions that are applicable to the entire Program shall
+be treated as though they were included in this License, to the extent
+that they are valid under applicable law.  If additional permissions
+apply only to part of the Program, that part may be used separately
+under those permissions, but the entire Program remains governed by
+this License without regard to the additional permissions.
+
+  When you convey a copy of a covered work, you may at your option
+remove any additional permissions from that copy, or from any part of
+it.  (Additional permissions may be written to require their own
+removal in certain cases when you modify the work.)  You may place
+additional permissions on material, added by you to a covered work,
+for which you have or can give appropriate copyright permission.
+
+  Notwithstanding any other provision of this License, for material you
+add to a covered work, you may (if authorized by the copyright holders of
+that material) supplement the terms of this License with terms:
+
+    a) Disclaiming warranty or limiting liability differently from the
+    terms of sections 15 and 16 of this License; or
+
+    b) Requiring preservation of specified reasonable legal notices or
+    author attributions in that material or in the Appropriate Legal
+    Notices displayed by works containing it; or
+
+    c) Prohibiting misrepresentation of the origin of that material, or
+    requiring that modified versions of such material be marked in
+    reasonable ways as different from the original version; or
+
+    d) Limiting the use for publicity purposes of names of licensors or
+    authors of the material; or
+
+    e) Declining to grant rights under trademark law for use of some
+    trade names, trademarks, or service marks; or
+
+    f) Requiring indemnification of licensors and authors of that
+    material by anyone who conveys the material (or modified versions of
+    it) with contractual assumptions of liability to the recipient, for
+    any liability that these contractual assumptions directly impose on
+    those licensors and authors.
+
+  All other non-permissive additional terms are considered "further
+restrictions" within the meaning of section 10.  If the Program as you
+received it, or any part of it, contains a notice stating that it is
+governed by this License along with a term that is a further
+restriction, you may remove that term.  If a license document contains
+a further restriction but permits relicensing or conveying under this
+License, you may add to a covered work material governed by the terms
+of that license document, provided that the further restriction does
+not survive such relicensing or conveying.
+
+  If you add terms to a covered work in accord with this section, you
+must place, in the relevant source files, a statement of the
+additional terms that apply to those files, or a notice indicating
+where to find the applicable terms.
+
+  Additional terms, permissive or non-permissive, may be stated in the
+form of a separately written license, or stated as exceptions;
+the above requirements apply either way.
+
+  8. Termination.
+
+  You may not propagate or modify a covered work except as expressly
+provided under this License.  Any attempt otherwise to propagate or
+modify it is void, and will automatically terminate your rights under
+this License (including any patent licenses granted under the third
+paragraph of section 11).
+
+  However, if you cease all violation of this License, then your
+license from a particular copyright holder is reinstated (a)
+provisionally, unless and until the copyright holder explicitly and
+finally terminates your license, and (b) permanently, if the copyright
+holder fails to notify you of the violation by some reasonable means
+prior to 60 days after the cessation.
+
+  Moreover, your license from a particular copyright holder is
+reinstated permanently if the copyright holder notifies you of the
+violation by some reasonable means, this is the first time you have
+received notice of violation of this License (for any work) from that
+copyright holder, and you cure the violation prior to 30 days after
+your receipt of the notice.
+
+  Termination of your rights under this section does not terminate the
+licenses of parties who have received copies or rights from you under
+this License.  If your rights have been terminated and not permanently
+reinstated, you do not qualify to receive new licenses for the same
+material under section 10.
+
+  9. Acceptance Not Required for Having Copies.
+
+  You are not required to accept this License in order to receive or
+run a copy of the Program.  Ancillary propagation of a covered work
+occurring solely as a consequence of using peer-to-peer transmission
+to receive a copy likewise does not require acceptance.  However,
+nothing other than this License grants you permission to propagate or
+modify any covered work.  These actions infringe copyright if you do
+not accept this License.  Therefore, by modifying or propagating a
+covered work, you indicate your acceptance of this License to do so.
+
+  10. Automatic Licensing of Downstream Recipients.
+
+  Each time you convey a covered work, the recipient automatically
+receives a license from the original licensors, to run, modify and
+propagate that work, subject to this License.  You are not responsible
+for enforcing compliance by third parties with this License.
+
+  An "entity transaction" is a transaction transferring control of an
+organization, or substantially all assets of one, or subdividing an
+organization, or merging organizations.  If propagation of a covered
+work results from an entity transaction, each party to that
+transaction who receives a copy of the work also receives whatever
+licenses to the work the party's predecessor in interest had or could
+give under the previous paragraph, plus a right to possession of the
+Corresponding Source of the work from the predecessor in interest, if
+the predecessor has it or can get it with reasonable efforts.
+
+  You may not impose any further restrictions on the exercise of the
+rights granted or affirmed under this License.  For example, you may
+not impose a license fee, royalty, or other charge for exercise of
+rights granted under this License, and you may not initiate litigation
+(including a cross-claim or counterclaim in a lawsuit) alleging that
+any patent claim is infringed by making, using, selling, offering for
+sale, or importing the Program or any portion of it.
+
+  11. Patents.
+
+  A "contributor" is a copyright holder who authorizes use under this
+License of the Program or a work on which the Program is based.  The
+work thus licensed is called the contributor's "contributor version".
+
+  A contributor's "essential patent claims" are all patent claims
+owned or controlled by the contributor, whether already acquired or
+hereafter acquired, that would be infringed by some manner, permitted
+by this License, of making, using, or selling its contributor version,
+but do not include claims that would be infringed only as a
+consequence of further modification of the contributor version.  For
+purposes of this definition, "control" includes the right to grant
+patent sublicenses in a manner consistent with the requirements of
+this License.
+
+  Each contributor grants you a non-exclusive, worldwide, royalty-free
+patent license under the contributor's essential patent claims, to
+make, use, sell, offer for sale, import and otherwise run, modify and
+propagate the contents of its contributor version.
+
+  In the following three paragraphs, a "patent license" is any express
+agreement or commitment, however denominated, not to enforce a patent
+(such as an express permission to practice a patent or covenant not to
+sue for patent infringement).  To "grant" such a patent license to a
+party means to make such an agreement or commitment not to enforce a
+patent against the party.
+
+  If you convey a covered work, knowingly relying on a patent license,
+and the Corresponding Source of the work is not available for anyone
+to copy, free of charge and under the terms of this License, through a
+publicly available network server or other readily accessible means,
+then you must either (1) cause the Corresponding Source to be so
+available, or (2) arrange to deprive yourself of the benefit of the
+patent license for this particular work, or (3) arrange, in a manner
+consistent with the requirements of this License, to extend the patent
+license to downstream recipients.  "Knowingly relying" means you have
+actual knowledge that, but for the patent license, your conveying the
+covered work in a country, or your recipient's use of the covered work
+in a country, would infringe one or more identifiable patents in that
+country that you have reason to believe are valid.
+
+  If, pursuant to or in connection with a single transaction or
+arrangement, you convey, or propagate by procuring conveyance of, a
+covered work, and grant a patent license to some of the parties
+receiving the covered work authorizing them to use, propagate, modify
+or convey a specific copy of the covered work, then the patent license
+you grant is automatically extended to all recipients of the covered
+work and works based on it.
+
+  A patent license is "discriminatory" if it does not include within
+the scope of its coverage, prohibits the exercise of, or is
+conditioned on the non-exercise of one or more of the rights that are
+specifically granted under this License.  You may not convey a covered
+work if you are a party to an arrangement with a third party that is
+in the business of distributing software, under which you make payment
+to the third party based on the extent of your activity of conveying
+the work, and under which the third party grants, to any of the
+parties who would receive the covered work from you, a discriminatory
+patent license (a) in connection with copies of the covered work
+conveyed by you (or copies made from those copies), or (b) primarily
+for and in connection with specific products or compilations that
+contain the covered work, unless you entered into that arrangement,
+or that patent license was granted, prior to 28 March 2007.
+
+  Nothing in this License shall be construed as excluding or limiting
+any implied license or other defenses to infringement that may
+otherwise be available to you under applicable patent law.
+
+  12. No Surrender of Others' Freedom.
+
+  If conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License.  If you cannot convey a
+covered work so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you may
+not convey it at all.  For example, if you agree to terms that obligate you
+to collect a royalty for further conveying from those to whom you convey
+the Program, the only way you could satisfy both those terms and this
+License would be to refrain entirely from conveying the Program.
+
+  13. Use with the GNU Affero General Public License.
+
+  Notwithstanding any other provision of this License, you have
+permission to link or combine any covered work with a work licensed
+under version 3 of the GNU Affero General Public License into a single
+combined work, and to convey the resulting work.  The terms of this
+License will continue to apply to the part which is the covered work,
+but the special requirements of the GNU Affero General Public License,
+section 13, concerning interaction through a network will apply to the
+combination as such.
+
+  14. Revised Versions of this License.
+
+  The Free Software Foundation may publish revised and/or new versions of
+the GNU General Public License from time to time.  Such new versions will
+be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.
+
+  Each version is given a distinguishing version number.  If the
+Program specifies that a certain numbered version of the GNU General
+Public License "or any later version" applies to it, you have the
+option of following the terms and conditions either of that numbered
+version or of any later version published by the Free Software
+Foundation.  If the Program does not specify a version number of the
+GNU General Public License, you may choose any version ever published
+by the Free Software Foundation.
+
+  If the Program specifies that a proxy can decide which future
+versions of the GNU General Public License can be used, that proxy's
+public statement of acceptance of a version permanently authorizes you
+to choose that version for the Program.
+
+  Later license versions may give you additional or different
+permissions.  However, no additional obligations are imposed on any
+author or copyright holder as a result of your choosing to follow a
+later version.
+
+  15. Disclaimer of Warranty.
+
+  THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
+APPLICABLE LAW.  EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
+HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY
+OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
+THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
+PURPOSE.  THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM
+IS WITH YOU.  SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
+ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
+
+  16. Limitation of Liability.
+
+  IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
+THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
+GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE
+USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF
+DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
+PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),
+EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF
+SUCH DAMAGES.
+
+  17. Interpretation of Sections 15 and 16.
+
+  If the disclaimer of warranty and limitation of liability provided
+above cannot be given local legal effect according to their terms,
+reviewing courts shall apply local law that most closely approximates
+an absolute waiver of all civil liability in connection with the
+Program, unless a warranty or assumption of liability accompanies a
+copy of the Program in return for a fee.
+
+                     END OF TERMS AND CONDITIONS

+                   GNU LESSER GENERAL PUBLIC LICENSE
+                       Version 3, 29 June 2007
+
+ Copyright (C) 2007 Free Software Foundation, Inc. <https://fsf.org/>
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+
+  This version of the GNU Lesser General Public License incorporates
+the terms and conditions of version 3 of the GNU General Public
+License, supplemented by the additional permissions listed below.
+
+  0. Additional Definitions.
+
+  As used herein, "this License" refers to version 3 of the GNU Lesser
+General Public License, and the "GNU GPL" refers to version 3 of the GNU
+General Public License.
+
+  "The Library" refers to a covered work governed by this License,
+other than an Application or a Combined Work as defined below.
+
+  An "Application" is any work that makes use of an interface provided
+by the Library, but which is not otherwise based on the Library.
+Defining a subclass of a class defined by the Library is deemed a mode
+of using an interface provided by the Library.
+
+  A "Combined Work" is a work produced by combining or linking an
+Application with the Library.  The particular version of the Library
+with which the Combined Work was made is also called the "Linked
+Version".
+
+  The "Minimal Corresponding Source" for a Combined Work means the
+Corresponding Source for the Combined Work, excluding any source code
+for portions of the Combined Work that, considered in isolation, are
+based on the Application, and not on the Linked Version.
+
+  The "Corresponding Application Code" for a Combined Work means the
+object code and/or source code for the Application, including any data
+and utility programs needed for reproducing the Combined Work from the
+Application, but excluding the System Libraries of the Combined Work.
+
+  1. Exception to Section 3 of the GNU GPL.
+
+  You may convey a covered work under sections 3 and 4 of this License
+without being bound by section 3 of the GNU GPL.
+
+  2. Conveying Modified Versions.
+
+  If you modify a copy of the Library, and, in your modifications, a
+facility refers to a function or data to be supplied by an Application
+that uses the facility (other than as an argument passed when the
+facility is invoked), then you may convey a copy of the modified
+version:
+
+   a) under this License, provided that you make a good faith effort to
+   ensure that, in the event an Application does not supply the
+   function or data, the facility still operates, and performs
+   whatever part of its purpose remains meaningful, or
+
+   b) under the GNU GPL, with none of the additional permissions of
+   this License applicable to that copy.
+
+  3. Object Code Incorporating Material from Library Header Files.
+
+  The object code form of an Application may incorporate material from
+a header file that is part of the Library.  You may convey such object
+code under terms of your choice, provided that, if the incorporated
+material is not limited to numerical parameters, data structure
+layouts and accessors, or small macros, inline functions and templates
+(ten or fewer lines in length), you do both of the following:
+
+   a) Give prominent notice with each copy of the object code that the
+   Library is used in it and that the Library and its use are
+   covered by this License.
+
+   b) Accompany the object code with a copy of the GNU GPL and this license
+   document.
+
+  4. Combined Works.
+
+  You may convey a Combined Work under terms of your choice that,
+taken together, effectively do not restrict modification of the
+portions of the Library contained in the Combined Work and reverse
+engineering for debugging such modifications, if you also do each of
+the following:
+
+   a) Give prominent notice with each copy of the Combined Work that
+   the Library is used in it and that the Library and its use are
+   covered by this License.
+
+   b) Accompany the Combined Work with a copy of the GNU GPL and this license
+   document.
+
+   c) For a Combined Work that displays copyright notices during
+   execution, include the copyright notice for the Library among
+   these notices, as well as a reference directing the user to the
+   copies of the GNU GPL and this license document.
+
+   d) Do one of the following:
+
+       0) Convey the Minimal Corresponding Source under the terms of this
+       License, and the Corresponding Application Code in a form
+       suitable for, and under terms that permit, the user to
+       recombine or relink the Application with a modified version of
+       the Linked Version to produce a modified Combined Work, in the
+       manner specified by section 6 of the GNU GPL for conveying
+       Corresponding Source.
+
+       1) Use a suitable shared library mechanism for linking with the
+       Library.  A suitable mechanism is one that (a) uses at run time
+       a copy of the Library already present on the user's computer
+       system, and (b) will operate properly with a modified version
+       of the Library that is interface-compatible with the Linked
+       Version.
+
+   e) Provide Installation Information, but only if you would otherwise
+   be required to provide such information under section 6 of the
+   GNU GPL, and only to the extent that such information is
+   necessary to install and execute a modified version of the
+   Combined Work produced by recombining or relinking the
+   Application with a modified version of the Linked Version. (If
+   you use option 4d0, the Installation Information must accompany
+   the Minimal Corresponding Source and Corresponding Application
+   Code. If you use option 4d1, you must provide the Installation
+   Information in the manner specified by section 6 of the GNU GPL
+   for conveying Corresponding Source.)
+
+  5. Combined Libraries.
+
+  You may place library facilities that are a work based on the
+Library side by side in a single library together with other library
+facilities that are not Applications and are not covered by this
+License, and convey such a combined library under terms of your
+choice, if you do both of the following:
+
+   a) Accompany the combined library with a copy of the same work based
+   on the Library, uncombined with any other library facilities,
+   conveyed under the terms of this License.
+
+   b) Give prominent notice with the combined library that part of it
+   is a work based on the Library, and explaining where to find the
+   accompanying uncombined form of the same work.
+
+  6. Revised Versions of the GNU Lesser General Public License.
+
+  The Free Software Foundation may publish revised and/or new versions
+of the GNU Lesser General Public License from time to time. Such new
+versions will be similar in spirit to the present version, but may
+differ in detail to address new problems or concerns.
+
+  Each version is given a distinguishing version number. If the
+Library as you received it specifies that a certain numbered version
+of the GNU Lesser General Public License "or any later version"
+applies to it, you have the option of following the terms and
+conditions either of that published version or of any later version
+published by the Free Software Foundation. If the Library as you
+received it does not specify a version number of the GNU Lesser
+General Public License, you may choose any version of the GNU Lesser
+General Public License ever published by the Free Software Foundation.
+
+  If the Library as you received it specifies that a proxy can decide
+whether future versions of the GNU Lesser General Public License shall
+apply, that proxy's public statement of acceptance of any version is
+permanent authorization for you to choose that version for the
+Library.

+                    GNU GENERAL PUBLIC LICENSE
+                       Version 3, 29 June 2007
+
+ Copyright (C) 2007 Free Software Foundation, Inc. <https://fsf.org/>
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+                            Preamble
+
+  The GNU General Public License is a free, copyleft license for
+software and other kinds of works.
+
+  The licenses for most software and other practical works are designed
+to take away your freedom to share and change the works.  By contrast,
+the GNU General Public License is intended to guarantee your freedom to
+share and change all versions of a program--to make sure it remains free
+software for all its users.  We, the Free Software Foundation, use the
+GNU General Public License for most of our software; it applies also to
+any other work released this way by its authors.  You can apply it to
+your programs, too.
+
+  When we speak of free software, we are referring to freedom, not
+price.  Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+them if you wish), that you receive source code or can get it if you
+want it, that you can change the software or use pieces of it in new
+free programs, and that you know you can do these things.
+
+  To protect your rights, we need to prevent others from denying you
+these rights or asking you to surrender the rights.  Therefore, you have
+certain responsibilities if you distribute copies of the software, or if
+you modify it: responsibilities to respect the freedom of others.
+
+  For example, if you distribute copies of such a program, whether
+gratis or for a fee, you must pass on to the recipients the same
+freedoms that you received.  You must make sure that they, too, receive
+or can get the source code.  And you must show them these terms so they
+know their rights.
+
+  Developers that use the GNU GPL protect your rights with two steps:
+(1) assert copyright on the software, and (2) offer you this License
+giving you legal permission to copy, distribute and/or modify it.
+
+  For the developers' and authors' protection, the GPL clearly explains
+that there is no warranty for this free software.  For both users' and
+authors' sake, the GPL requires that modified versions be marked as
+changed, so that their problems will not be attributed erroneously to
+authors of previous versions.
+
+  Some devices are designed to deny users access to install or run
+modified versions of the software inside them, although the manufacturer
+can do so.  This is fundamentally incompatible with the aim of
+protecting users' freedom to change the software.  The systematic
+pattern of such abuse occurs in the area of products for individuals to
+use, which is precisely where it is most unacceptable.  Therefore, we
+have designed this version of the GPL to prohibit the practice for those
+products.  If such problems arise substantially in other domains, we
+stand ready to extend this provision to those domains in future versions
+of the GPL, as needed to protect the freedom of users.
+
+  Finally, every program is threatened constantly by software patents.
+States should not allow patents to restrict development and use of
+software on general-purpose computers, but in those that do, we wish to
+avoid the special danger that patents applied to a free program could
+make it effectively proprietary.  To prevent this, the GPL assures that
+patents cannot be used to render the program non-free.
+
+  The precise terms and conditions for copying, distribution and
+modification follow.
+
+                       TERMS AND CONDITIONS
+
+  0. Definitions.
+
+  "This License" refers to version 3 of the GNU General Public License.
+
+  "Copyright" also means copyright-like laws that apply to other kinds of
+works, such as semiconductor masks.
+
+  "The Program" refers to any copyrightable work licensed under this
+License.  Each licensee is addressed as "you".  "Licensees" and
+"recipients" may be individuals or organizations.
+
+  To "modify" a work means to copy from or adapt all or part of the work
+in a fashion requiring copyright permission, other than the making of an
+exact copy.  The resulting work is called a "modified version" of the
+earlier work or a work "based on" the earlier work.
+
+  A "covered work" means either the unmodified Program or a work based
+on the Program.
+
+  To "propagate" a work means to do anything with it that, without
+permission, would make you directly or secondarily liable for
+infringement under applicable copyright law, except executing it on a
+computer or modifying a private copy.  Propagation includes copying,
+distribution (with or without modification), making available to the
+public, and in some countries other activities as well.
+
+  To "convey" a work means any kind of propagation that enables other
+parties to make or receive copies.  Mere interaction with a user through
+a computer network, with no transfer of a copy, is not conveying.
+
+  An interactive user interface displays "Appropriate Legal Notices"
+to the extent that it includes a convenient and prominently visible
+feature that (1) displays an appropriate copyright notice, and (2)
+tells the user that there is no warranty for the work (except to the
+extent that warranties are provided), that licensees may convey the
+work under this License, and how to view a copy of this License.  If
+the interface presents a list of user commands or options, such as a
+menu, a prominent item in the list meets this criterion.
+
+  1. Source Code.
+
+  The "source code" for a work means the preferred form of the work
+for making modifications to it.  "Object code" means any non-source
+form of a work.
+
+  A "Standard Interface" means an interface that either is an official
+standard defined by a recognized standards body, or, in the case of
+interfaces specified for a particular programming language, one that
+is widely used among developers working in that language.
+
+  The "System Libraries" of an executable work include anything, other
+than the work as a whole, that (a) is included in the normal form of
+packaging a Major Component, but which is not part of that Major
+Component, and (b) serves only to enable use of the work with that
+Major Component, or to implement a Standard Interface for which an
+implementation is available to the public in source code form.  A
+"Major Component", in this context, means a major essential component
+(kernel, window system, and so on) of the specific operating system
+(if any) on which the executable work runs, or a compiler used to
+produce the work, or an object code interpreter used to run it.
+
+  The "Corresponding Source" for a work in object code form means all
+the source code needed to generate, install, and (for an executable
+work) run the object code and to modify the work, including scripts to
+control those activities.  However, it does not include the work's
+System Libraries, or general-purpose tools or generally available free
+programs which are used unmodified in performing those activities but
+which are not part of the work.  For example, Corresponding Source
+includes interface definition files associated with source files for
+the work, and the source code for shared libraries and dynamically
+linked subprograms that the work is specifically designed to require,
+such as by intimate data communication or control flow between those
+subprograms and other parts of the work.
+
+  The Corresponding Source need not include anything that users
+can regenerate automatically from other parts of the Corresponding
+Source.
+
+  The Corresponding Source for a work in source code form is that
+same work.
+
+  2. Basic Permissions.
+
+  All rights granted under this License are granted for the term of
+copyright on the Program, and are irrevocable provided the stated
+conditions are met.  This License explicitly affirms your unlimited
+permission to run the unmodified Program.  The output from running a
+covered work is covered by this License only if the output, given its
+content, constitutes a covered work.  This License acknowledges your
+rights of fair use or other equivalent, as provided by copyright law.
+
+  You may make, run and propagate covered works that you do not
+convey, without conditions so long as your license otherwise remains
+in force.  You may convey covered works to others for the sole purpose
+of having them make modifications exclusively for you, or provide you
+with facilities for running those works, provided that you comply with
+the terms of this License in conveying all material for which you do
+not control copyright.  Those thus making or running the covered works
+for you must do so exclusively on your behalf, under your direction
+and control, on terms that prohibit them from making any copies of
+your copyrighted material outside their relationship with you.
+
+  Conveying under any other circumstances is permitted solely under
+the conditions stated below.  Sublicensing is not allowed; section 10
+makes it unnecessary.
+
+  3. Protecting Users' Legal Rights From Anti-Circumvention Law.
+
+  No covered work shall be deemed part of an effective technological
+measure under any applicable law fulfilling obligations under article
+11 of the WIPO copyright treaty adopted on 20 December 1996, or
+similar laws prohibiting or restricting circumvention of such
+measures.
+
+  When you convey a covered work, you waive any legal power to forbid
+circumvention of technological measures to the extent such circumvention
+is effected by exercising rights under this License with respect to
+the covered work, and you disclaim any intention to limit operation or
+modification of the work as a means of enforcing, against the work's
+users, your or third parties' legal rights to forbid circumvention of
+technological measures.
+
+  4. Conveying Verbatim Copies.
+
+  You may convey verbatim copies of the Program's source code as you
+receive it, in any medium, provided that you conspicuously and
+appropriately publish on each copy an appropriate copyright notice;
+keep intact all notices stating that this License and any
+non-permissive terms added in accord with section 7 apply to the code;
+keep intact all notices of the absence of any warranty; and give all
+recipients a copy of this License along with the Program.
+
+  You may charge any price or no price for each copy that you convey,
+and you may offer support or warranty protection for a fee.
+
+  5. Conveying Modified Source Versions.
+
+  You may convey a work based on the Program, or the modifications to
+produce it from the Program, in the form of source code under the
+terms of section 4, provided that you also meet all of these conditions:
+
+    a) The work must carry prominent notices stating that you modified
+    it, and giving a relevant date.
+
+    b) The work must carry prominent notices stating that it is
+    released under this License and any conditions added under section
+    7.  This requirement modifies the requirement in section 4 to
+    "keep intact all notices".
+
+    c) You must license the entire work, as a whole, under this
+    License to anyone who comes into possession of a copy.  This
+    License will therefore apply, along with any applicable section 7
+    additional terms, to the whole of the work, and all its parts,
+    regardless of how they are packaged.  This License gives no
+    permission to license the work in any other way, but it does not
+    invalidate such permission if you have separately received it.
+
+    d) If the work has interactive user interfaces, each must display
+    Appropriate Legal Notices; however, if the Program has interactive
+    interfaces that do not display Appropriate Legal Notices, your
+    work need not make them do so.
+
+  A compilation of a covered work with other separate and independent
+works, which are not by their nature extensions of the covered work,
+and which are not combined with it such as to form a larger program,
+in or on a volume of a storage or distribution medium, is called an
+"aggregate" if the compilation and its resulting copyright are not
+used to limit the access or legal rights of the compilation's users
+beyond what the individual works permit.  Inclusion of a covered work
+in an aggregate does not cause this License to apply to the other
+parts of the aggregate.
+
+  6. Conveying Non-Source Forms.
+
+  You may convey a covered work in object code form under the terms
+of sections 4 and 5, provided that you also convey the
+machine-readable Corresponding Source under the terms of this License,
+in one of these ways:
+
+    a) Convey the object code in, or embodied in, a physical product
+    (including a physical distribution medium), accompanied by the
+    Corresponding Source fixed on a durable physical medium
+    customarily used for software interchange.
+
+    b) Convey the object code in, or embodied in, a physical product
+    (including a physical distribution medium), accompanied by a
+    written offer, valid for at least three years and valid for as
+    long as you offer spare parts or customer support for that product
+    model, to give anyone who possesses the object code either (1) a
+    copy of the Corresponding Source for all the software in the
+    product that is covered by this License, on a durable physical
+    medium customarily used for software interchange, for a price no
+    more than your reasonable cost of physically performing this
+    conveying of source, or (2) access to copy the
+    Corresponding Source from a network server at no charge.
+
+    c) Convey individual copies of the object code with a copy of the
+    written offer to provide the Corresponding Source.  This
+    alternative is allowed only occasionally and noncommercially, and
+    only if you received the object code with such an offer, in accord
+    with subsection 6b.
+
+    d) Convey the object code by offering access from a designated
+    place (gratis or for a charge), and offer equivalent access to the
+    Corresponding Source in the same way through the same place at no
+    further charge.  You need not require recipients to copy the
+    Corresponding Source along with the object code.  If the place to
+    copy the object code is a network server, the Corresponding Source
+    may be on a different server (operated by you or a third party)
+    that supports equivalent copying facilities, provided you maintain
+    clear directions next to the object code saying where to find the
+    Corresponding Source.  Regardless of what server hosts the
+    Corresponding Source, you remain obligated to ensure that it is
+    available for as long as needed to satisfy these requirements.
+
+    e) Convey the object code using peer-to-peer transmission, provided
+    you inform other peers where the object code and Corresponding
+    Source of the work are being offered to the general public at no
+    charge under subsection 6d.
+
+  A separable portion of the object code, whose source code is excluded
+from the Corresponding Source as a System Library, need not be
+included in conveying the object code work.
+
+  A "User Product" is either (1) a "consumer product", which means any
+tangible personal property which is normally used for personal, family,
+or household purposes, or (2) anything designed or sold for incorporation
+into a dwelling.  In determining whether a product is a consumer product,
+doubtful cases shall be resolved in favor of coverage.  For a particular
+product received by a particular user, "normally used" refers to a
+typical or common use of that class of product, regardless of the status
+of the particular user or of the way in which the particular user
+actually uses, or expects or is expected to use, the product.  A product
+is a consumer product regardless of whether the product has substantial
+commercial, industrial or non-consumer uses, unless such uses represent
+the only significant mode of use of the product.
+
+  "Installation Information" for a User Product means any methods,
+procedures, authorization keys, or other information required to install
+and execute modified versions of a covered work in that User Product from
+a modified version of its Corresponding Source.  The information must
+suffice to ensure that the continued functioning of the modified object
+code is in no case prevented or interfered with solely because
+modification has been made.
+
+  If you convey an object code work under this section in, or with, or
+specifically for use in, a User Product, and the conveying occurs as
+part of a transaction in which the right of possession and use of the
+User Product is transferred to the recipient in perpetuity or for a
+fixed term (regardless of how the transaction is characterized), the
+Corresponding Source conveyed under this section must be accompanied
+by the Installation Information.  But this requirement does not apply
+if neither you nor any third party retains the ability to install
+modified object code on the User Product (for example, the work has
+been installed in ROM).
+
+  The requirement to provide Installation Information does not include a
+requirement to continue to provide support service, warranty, or updates
+for a work that has been modified or installed by the recipient, or for
+the User Product in which it has been modified or installed.  Access to a
+network may be denied when the modification itself materially and
+adversely affects the operation of the network or violates the rules and
+protocols for communication across the network.
+
+  Corresponding Source conveyed, and Installation Information provided,
+in accord with this section must be in a format that is publicly
+documented (and with an implementation available to the public in
+source code form), and must require no special password or key for
+unpacking, reading or copying.
+
+  7. Additional Terms.
+
+  "Additional permissions" are terms that supplement the terms of this
+License by making exceptions from one or more of its conditions.
+Additional permissions that are applicable to the entire Program shall
+be treated as though they were included in this License, to the extent
+that they are valid under applicable law.  If additional permissions
+apply only to part of the Program, that part may be used separately
+under those permissions, but the entire Program remains governed by
+this License without regard to the additional permissions.
+
+  When you convey a copy of a covered work, you may at your option
+remove any additional permissions from that copy, or from any part of
+it.  (Additional permissions may be written to require their own
+removal in certain cases when you modify the work.)  You may place
+additional permissions on material, added by you to a covered work,
+for which you have or can give appropriate copyright permission.
+
+  Notwithstanding any other provision of this License, for material you
+add to a covered work, you may (if authorized by the copyright holders of
+that material) supplement the terms of this License with terms:
+
+    a) Disclaiming warranty or limiting liability differently from the
+    terms of sections 15 and 16 of this License; or
+
+    b) Requiring preservation of specified reasonable legal notices or
+    author attributions in that material or in the Appropriate Legal
+    Notices displayed by works containing it; or
+
+    c) Prohibiting misrepresentation of the origin of that material, or
+    requiring that modified versions of such material be marked in
+    reasonable ways as different from the original version; or
+
+    d) Limiting the use for publicity purposes of names of licensors or
+    authors of the material; or
+
+    e) Declining to grant rights under trademark law for use of some
+    trade names, trademarks, or service marks; or
+
+    f) Requiring indemnification of licensors and authors of that
+    material by anyone who conveys the material (or modified versions of
+    it) with contractual assumptions of liability to the recipient, for
+    any liability that these contractual assumptions directly impose on
+    those licensors and authors.
+
+  All other non-permissive additional terms are considered "further
+restrictions" within the meaning of section 10.  If the Program as you
+received it, or any part of it, contains a notice stating that it is
+governed by this License along with a term that is a further
+restriction, you may remove that term.  If a license document contains
+a further restriction but permits relicensing or conveying under this
+License, you may add to a covered work material governed by the terms
+of that license document, provided that the further restriction does
+not survive such relicensing or conveying.
+
+  If you add terms to a covered work in accord with this section, you
+must place, in the relevant source files, a statement of the
+additional terms that apply to those files, or a notice indicating
+where to find the applicable terms.
+
+  Additional terms, permissive or non-permissive, may be stated in the
+form of a separately written license, or stated as exceptions;
+the above requirements apply either way.
+
+  8. Termination.
+
+  You may not propagate or modify a covered work except as expressly
+provided under this License.  Any attempt otherwise to propagate or
+modify it is void, and will automatically terminate your rights under
+this License (including any patent licenses granted under the third
+paragraph of section 11).
+
+  However, if you cease all violation of this License, then your
+license from a particular copyright holder is reinstated (a)
+provisionally, unless and until the copyright holder explicitly and
+finally terminates your license, and (b) permanently, if the copyright
+holder fails to notify you of the violation by some reasonable means
+prior to 60 days after the cessation.
+
+  Moreover, your license from a particular copyright holder is
+reinstated permanently if the copyright holder notifies you of the
+violation by some reasonable means, this is the first time you have
+received notice of violation of this License (for any work) from that
+copyright holder, and you cure the violation prior to 30 days after
+your receipt of the notice.
+
+  Termination of your rights under this section does not terminate the
+licenses of parties who have received copies or rights from you under
+this License.  If your rights have been terminated and not permanently
+reinstated, you do not qualify to receive new licenses for the same
+material under section 10.
+
+  9. Acceptance Not Required for Having Copies.
+
+  You are not required to accept this License in order to receive or
+run a copy of the Program.  Ancillary propagation of a covered work
+occurring solely as a consequence of using peer-to-peer transmission
+to receive a copy likewise does not require acceptance.  However,
+nothing other than this License grants you permission to propagate or
+modify any covered work.  These actions infringe copyright if you do
+not accept this License.  Therefore, by modifying or propagating a
+covered work, you indicate your acceptance of this License to do so.
+
+  10. Automatic Licensing of Downstream Recipients.
+
+  Each time you convey a covered work, the recipient automatically
+receives a license from the original licensors, to run, modify and
+propagate that work, subject to this License.  You are not responsible
+for enforcing compliance by third parties with this License.
+
+  An "entity transaction" is a transaction transferring control of an
+organization, or substantially all assets of one, or subdividing an
+organization, or merging organizations.  If propagation of a covered
+work results from an entity transaction, each party to that
+transaction who receives a copy of the work also receives whatever
+licenses to the work the party's predecessor in interest had or could
+give under the previous paragraph, plus a right to possession of the
+Corresponding Source of the work from the predecessor in interest, if
+the predecessor has it or can get it with reasonable efforts.
+
+  You may not impose any further restrictions on the exercise of the
+rights granted or affirmed under this License.  For example, you may
+not impose a license fee, royalty, or other charge for exercise of
+rights granted under this License, and you may not initiate litigation
+(including a cross-claim or counterclaim in a lawsuit) alleging that
+any patent claim is infringed by making, using, selling, offering for
+sale, or importing the Program or any portion of it.
+
+  11. Patents.
+
+  A "contributor" is a copyright holder who authorizes use under this
+License of the Program or a work on which the Program is based.  The
+work thus licensed is called the contributor's "contributor version".
+
+  A contributor's "essential patent claims" are all patent claims
+owned or controlled by the contributor, whether already acquired or
+hereafter acquired, that would be infringed by some manner, permitted
+by this License, of making, using, or selling its contributor version,
+but do not include claims that would be infringed only as a
+consequence of further modification of the contributor version.  For
+purposes of this definition, "control" includes the right to grant
+patent sublicenses in a manner consistent with the requirements of
+this License.
+
+  Each contributor grants you a non-exclusive, worldwide, royalty-free
+patent license under the contributor's essential patent claims, to
+make, use, sell, offer for sale, import and otherwise run, modify and
+propagate the contents of its contributor version.
+
+  In the following three paragraphs, a "patent license" is any express
+agreement or commitment, however denominated, not to enforce a patent
+(such as an express permission to practice a patent or covenant not to
+sue for patent infringement).  To "grant" such a patent license to a
+party means to make such an agreement or commitment not to enforce a
+patent against the party.
+
+  If you convey a covered work, knowingly relying on a patent license,
+and the Corresponding Source of the work is not available for anyone
+to copy, free of charge and under the terms of this License, through a
+publicly available network server or other readily accessible means,
+then you must either (1) cause the Corresponding Source to be so
+available, or (2) arrange to deprive yourself of the benefit of the
+patent license for this particular work, or (3) arrange, in a manner
+consistent with the requirements of this License, to extend the patent
+license to downstream recipients.  "Knowingly relying" means you have
+actual knowledge that, but for the patent license, your conveying the
+covered work in a country, or your recipient's use of the covered work
+in a country, would infringe one or more identifiable patents in that
+country that you have reason to believe are valid.
+
+  If, pursuant to or in connection with a single transaction or
+arrangement, you convey, or propagate by procuring conveyance of, a
+covered work, and grant a patent license to some of the parties
+receiving the covered work authorizing them to use, propagate, modify
+or convey a specific copy of the covered work, then the patent license
+you grant is automatically extended to all recipients of the covered
+work and works based on it.
+
+  A patent license is "discriminatory" if it does not include within
+the scope of its coverage, prohibits the exercise of, or is
+conditioned on the non-exercise of one or more of the rights that are
+specifically granted under this License.  You may not convey a covered
+work if you are a party to an arrangement with a third party that is
+in the business of distributing software, under which you make payment
+to the third party based on the extent of your activity of conveying
+the work, and under which the third party grants, to any of the
+parties who would receive the covered work from you, a discriminatory
+patent license (a) in connection with copies of the covered work
+conveyed by you (or copies made from those copies), or (b) primarily
+for and in connection with specific products or compilations that
+contain the covered work, unless you entered into that arrangement,
+or that patent license was granted, prior to 28 March 2007.
+
+  Nothing in this License shall be construed as excluding or limiting
+any implied license or other defenses to infringement that may
+otherwise be available to you under applicable patent law.
+
+  12. No Surrender of Others' Freedom.
+
+  If conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License.  If you cannot convey a
+covered work so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you may
+not convey it at all.  For example, if you agree to terms that obligate you
+to collect a royalty for further conveying from those to whom you convey
+the Program, the only way you could satisfy both those terms and this
+License would be to refrain entirely from conveying the Program.
+
+  13. Use with the GNU Affero General Public License.
+
+  Notwithstanding any other provision of this License, you have
+permission to link or combine any covered work with a work licensed
+under version 3 of the GNU Affero General Public License into a single
+combined work, and to convey the resulting work.  The terms of this
+License will continue to apply to the part which is the covered work,
+but the special requirements of the GNU Affero General Public License,
+section 13, concerning interaction through a network will apply to the
+combination as such.
+
+  14. Revised Versions of this License.
+
+  The Free Software Foundation may publish revised and/or new versions of
+the GNU General Public License from time to time.  Such new versions will
+be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.
+
+  Each version is given a distinguishing version number.  If the
+Program specifies that a certain numbered version of the GNU General
+Public License "or any later version" applies to it, you have the
+option of following the terms and conditions either of that numbered
+version or of any later version published by the Free Software
+Foundation.  If the Program does not specify a version number of the
+GNU General Public License, you may choose any version ever published
+by the Free Software Foundation.
+
+  If the Program specifies that a proxy can decide which future
+versions of the GNU General Public License can be used, that proxy's
+public statement of acceptance of a version permanently authorizes you
+to choose that version for the Program.
+
+  Later license versions may give you additional or different
+permissions.  However, no additional obligations are imposed on any
+author or copyright holder as a result of your choosing to follow a
+later version.
+
+  15. Disclaimer of Warranty.
+
+  THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
+APPLICABLE LAW.  EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
+HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY

+                   GNU LESSER GENERAL PUBLIC LICENSE
+                       Version 3, 29 June 2007
+
+ Copyright (C) 2007 Free Software Foundation, Inc. <https://fsf.org/>
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+
+  This version of the GNU Lesser General Public License incorporates
+the terms and conditions of version 3 of the GNU General Public
+License, supplemented by the additional permissions listed below.
+
+  0. Additional Definitions.
+
+  As used herein, "this License" refers to version 3 of the GNU Lesser
+General Public License, and the "GNU GPL" refers to version 3 of the GNU
+General Public License.
+
+  "The Library" refers to a covered work governed by this License,
+other than an Application or a Combined Work as defined below.
+
+  An "Application" is any work that makes use of an interface provided
+by the Library, but which is not otherwise based on the Library.
+Defining a subclass of a class defined by the Library is deemed a mode
+of using an interface provided by the Library.
+
+  A "Combined Work" is a work produced by combining or linking an
+Application with the Library.  The particular version of the Library
+with which the Combined Work was made is also called the "Linked
+Version".
+
+  The "Minimal Corresponding Source" for a Combined Work means the
+Corresponding Source for the Combined Work, excluding any source code
+for portions of the Combined Work that, considered in isolation, are
+based on the Application, and not on the Linked Version.
+
+  The "Corresponding Application Code" for a Combined Work means the
+object code and/or source code for the Application, including any data
+and utility programs needed for reproducing the Combined Work from the
+Application, but excluding the System Libraries of the Combined Work.
+
+  1. Exception to Section 3 of the GNU GPL.
+
+  You may convey a covered work under sections 3 and 4 of this License
+without being bound by section 3 of the GNU GPL.
+
+  2. Conveying Modified Versions.
+
+  If you modify a copy of the Library, and, in your modifications, a
+facility refers to a function or data to be supplied by an Application
+that uses the facility (other than as an argument passed when the
+facility is invoked), then you may convey a copy of the modified
+version:
+
+   a) under this License, provided that you make a good faith effort to
+   ensure that, in the event an Application does not supply the
+   function or data, the facility still operates, and performs
+   whatever part of its purpose remains meaningful, or
+
+   b) under the GNU GPL, with none of the additional permissions of
+   this License applicable to that copy.
+
+  3. Object Code Incorporating Material from Library Header Files.
+
+  The object code form of an Application may incorporate material from
+a header file that is part of the Library.  You may convey such object
+code under terms of your choice, provided that, if the incorporated
+material is not limited to numerical parameters, data structure
+layouts and accessors, or small macros, inline functions and templates
+(ten or fewer lines in length), you do both of the following:
+
+   a) Give prominent notice with each copy of the object code that the
+   Library is used in it and that the Library and its use are
+   covered by this License.
+
+   b) Accompany the object code with a copy of the GNU GPL and this license
+   document.
+
+  4. Combined Works.
+
+  You may convey a Combined Work under terms of your choice that,
+taken together, effectively do not restrict modification of the
+portions of the Library contained in the Combined Work and reverse
+engineering for debugging such modifications, if you also do each of
+the following:
+
+   a) Give prominent notice with each copy of the Combined Work that
+   the Library is used in it and that the Library and its use are
+   covered by this License.
+
+   b) Accompany the Combined Work with a copy of the GNU GPL and this license
+   document.
+
+   c) For a Combined Work that displays copyright notices during
+   execution, include the copyright notice for the Library among
+   these notices, as well as a reference directing the user to the
+   copies of the GNU GPL and this license document.
+
+   d) Do one of the following:
+
+       0) Convey the Minimal Corresponding Source under the terms of this
+       License, and the Corresponding Application Code in a form
+       suitable for, and under terms that permit, the user to
+       recombine or relink the Application with a modified version of
+       the Linked Version to produce a modified Combined Work, in the
+       manner specified by section 6 of the GNU GPL for conveying
+       Corresponding Source.
+
+       1) Use a suitable shared library mechanism for linking with the
+       Library.  A suitable mechanism is one that (a) uses at run time
+       a copy of the Library already present on the user's computer
+       system, and (b) will operate properly with a modified version
+       of the Library that is interface-compatible with the Linked
+       Version.
+
+   e) Provide Installation Information, but only if you would otherwise
+   be required to provide such information under section 6 of the
+   GNU GPL, and only to the extent that such information is
+   necessary to install and execute a modified version of the
+   Combined Work produced by recombining or relinking the
+   Application with a modified version of the Linked Version. (If
+   you use option 4d0, the Installation Information must accompany
+   the Minimal Corresponding Source and Corresponding Application
+   Code. If you use option 4d1, you must provide the Installation
+   Information in the manner specified by section 6 of the GNU GPL
+   for conveying Corresponding Source.)
+
+  5. Combined Libraries.
+
+  You may place library facilities that are a work based on the
+Library side by side in a single library together with other library
+facilities that are not Applications and are not covered by this
+License, and convey such a combined library under terms of your
+choice, if you do both of the following:
+
+   a) Accompany the combined library with a copy of the same work based
+   on the Library, uncombined with any other library facilities,
+   conveyed under the terms of this License.
+
+   b) Give prominent notice with the combined library that part of it
+   is a work based on the Library, and explaining where to find the
+   accompanying uncombined form of the same work.
+
+  6. Revised Versions of the GNU Lesser General Public License.
+
+  The Free Software Foundation may publish revised and/or new versions
+of the GNU Lesser General Public License from time to time. Such new
+versions will be similar in spirit to the present version, but may
+differ in detail to address new problems or concerns.
+
+  Each version is given a distinguishing version number. If the
+Library as you received it specifies that a certain numbered version
+of the GNU Lesser General Public License "or any later version"
+applies to it, you have the option of following the terms and
+conditions either of that published version or of any later version
+published by the Free Software Foundation. If the Library as you
+received it does not specify a version number of the GNU Lesser
+General Public License, you may choose any version of the GNU Lesser
+General Public License ever published by the Free Software Foundation.
+
+  If the Library as you received it specifies that a proxy can decide
+whether future versions of the GNU Lesser General Public License shall
+apply, that proxy's public statement of acceptance of any version is
+permanent authorization for you to choose that version for the
+Library.

+                    GNU GENERAL PUBLIC LICENSE
+                       Version 3, 29 June 2007
+
+ Copyright (C) 2007 Free Software Foundation, Inc. <https://fsf.org/>
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+                            Preamble
+
+  The GNU General Public License is a free, copyleft license for
+software and other kinds of works.
+
+  The licenses for most software and other practical works are designed
+to take away your freedom to share and change the works.  By contrast,
+the GNU General Public License is intended to guarantee your freedom to
+share and change all versions of a program--to make sure it remains free
+software for all its users.  We, the Free Software Foundation, use the
+GNU General Public License for most of our software; it applies also to
+any other work released this way by its authors.  You can apply it to
+your programs, too.
+
+  When we speak of free software, we are referring to freedom, not
+price.  Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+them if you wish), that you receive source code or can get it if you
+want it, that you can change the software or use pieces of it in new
+free programs, and that you know you can do these things.
+
+  To protect your rights, we need to prevent others from denying you
+these rights or asking you to surrender the rights.  Therefore, you have
+certain responsibilities if you distribute copies of the software, or if
+you modify it: responsibilities to respect the freedom of others.
+
+  For example, if you distribute copies of such a program, whether
+gratis or for a fee, you must pass on to the recipients the same
+freedoms that you received.  You must make sure that they, too, receive
+or can get the source code.  And you must show them these terms so they
+know their rights.
+
+  Developers that use the GNU GPL protect your rights with two steps:
+(1) assert copyright on the software, and (2) offer you this License
+giving you legal permission to copy, distribute and/or modify it.
+
+  For the developers' and authors' protection, the GPL clearly explains
+that there is no warranty for this free software.  For both users' and
+authors' sake, the GPL requires that modified versions be marked as
+changed, so that their problems will not be attributed erroneously to
+authors of previous versions.
+
+  Some devices are designed to deny users access to install or run
+modified versions of the software inside them, although the manufacturer
+can do so.  This is fundamentally incompatible with the aim of
+protecting users' freedom to change the software.  The systematic
+pattern of such abuse occurs in the area of products for individuals to
+use, which is precisely where it is most unacceptable.  Therefore, we
+have designed this version of the GPL to prohibit the practice for those
+products.  If such problems arise substantially in other domains, we
+stand ready to extend this provision to those domains in future versions
+of the GPL, as needed to protect the freedom of users.
+
+  Finally, every program is threatened constantly by software patents.
+States should not allow patents to restrict development and use of
+software on general-purpose computers, but in those that do, we wish to
+avoid the special danger that patents applied to a free program could
+make it effectively proprietary.  To prevent this, the GPL assures that
+patents cannot be used to render the program non-free.
+
+  The precise terms and conditions for copying, distribution and
+modification follow.
+
+                       TERMS AND CONDITIONS
+
+  0. Definitions.
+
+  "This License" refers to version 3 of the GNU General Public License.
+
+  "Copyright" also means copyright-like laws that apply to other kinds of
+works, such as semiconductor masks.
+
+  "The Program" refers to any copyrightable work licensed under this
+License.  Each licensee is addressed as "you".  "Licensees" and
+"recipients" may be individuals or organizations.
+
+  To "modify" a work means to copy from or adapt all or part of the work
+in a fashion requiring copyright permission, other than the making of an
+exact copy.  The resulting work is called a "modified version" of the
+earlier work or a work "based on" the earlier work.
+
+  A "covered work" means either the unmodified Program or a work based
+on the Program.
+
+  To "propagate" a work means to do anything with it that, without
+permission, would make you directly or secondarily liable for
+infringement under applicable copyright law, except executing it on a
+computer or modifying a private copy.  Propagation includes copying,
+distribution (with or without modification), making available to the
+public, and in some countries other activities as well.
+
+  To "convey" a work means any kind of propagation that enables other
+parties to make or receive copies.  Mere interaction with a user through
+a computer network, with no transfer of a copy, is not conveying.
+
+  An interactive user interface displays "Appropriate Legal Notices"
+to the extent that it includes a convenient and prominently visible
+feature that (1) displays an appropriate copyright notice, and (2)
+tells the user that there is no warranty for the work (except to the
+extent that warranties are provided), that licensees may convey the
+work under this License, and how to view a copy of this License.  If
+the interface presents a list of user commands or options, such as a
+menu, a prominent item in the list meets this criterion.
+
+  1. Source Code.
+
+  The "source code" for a work means the preferred form of the work
+for making modifications to it.  "Object code" means any non-source
+form of a work.
+
+  A "Standard Interface" means an interface that either is an official
+standard defined by a recognized standards body, or, in the case of
+interfaces specified for a particular programming language, one that
+is widely used among developers working in that language.
+
+  The "System Libraries" of an executable work include anything, other
+than the work as a whole, that (a) is included in the normal form of
+packaging a Major Component, but which is not part of that Major
+Component, and (b) serves only to enable use of the work with that
+Major Component, or to implement a Standard Interface for which an
+implementation is available to the public in source code form.  A
+"Major Component", in this context, means a major essential component
+(kernel, window system, and so on) of the specific operating system
+(if any) on which the executable work runs, or a compiler used to
+produce the work, or an object code interpreter used to run it.
+
+  The "Corresponding Source" for a work in object code form means all
+the source code needed to generate, install, and (for an executable
+work) run the object code and to modify the work, including scripts to
+control those activities.  However, it does not include the work's
+System Libraries, or general-purpose tools or generally available free
+programs which are used unmodified in performing those activities but
+which are not part of the work.  For example, Corresponding Source
+includes interface definition files associated with source files for
+the work, and the source code for shared libraries and dynamically
+linked subprograms that the work is specifically designed to require,
+such as by intimate data communication or control flow between those
+subprograms and other parts of the work.
+
+  The Corresponding Source need not include anything that users
+can regenerate automatically from other parts of the Corresponding
+Source.
+
+  The Corresponding Source for a work in source code form is that
+same work.
+
+  2. Basic Permissions.
+
+  All rights granted under this License are granted for the term of
+copyright on the Program, and are irrevocable provided the stated
+conditions are met.  This License explicitly affirms your unlimited
+permission to run the unmodified Program.  The output from running a
+covered work is covered by this License only if the output, given its
+content, constitutes a covered work.  This License acknowledges your
+rights of fair use or other equivalent, as provided by copyright law.
+
+  You may make, run and propagate covered works that you do not
+convey, without conditions so long as your license otherwise remains
+in force.  You may convey covered works to others for the sole purpose
+of having them make modifications exclusively for you, or provide you
+with facilities for running those works, provided that you comply with
+the terms of this License in conveying all material for which you do
+not control copyright.  Those thus making or running the covered works
+for you must do so exclusively on your behalf, under your direction
+and control, on terms that prohibit them from making any copies of
+your copyrighted material outside their relationship with you.
+
+  Conveying under any other circumstances is permitted solely under
+the conditions stated below.  Sublicensing is not allowed; section 10
+makes it unnecessary.
+
+  3. Protecting Users' Legal Rights From Anti-Circumvention Law.
+
+  No covered work shall be deemed part of an effective technological
+measure under any applicable law fulfilling obligations under article
+11 of the WIPO copyright treaty adopted on 20 December 1996, or
+similar laws prohibiting or restricting circumvention of such
+measures.
+
+  When you convey a covered work, you waive any legal power to forbid
+circumvention of technological measures to the extent such circumvention
+is effected by exercising rights under this License with respect to
+the covered work, and you disclaim any intention to limit operation or
+modification of the work as a means of enforcing, against the work's
+users, your or third parties' legal rights to forbid circumvention of
+technological measures.
+
+  4. Conveying Verbatim Copies.
+
+  You may convey verbatim copies of the Program's source code as you
+receive it, in any medium, provided that you conspicuously and
+appropriately publish on each copy an appropriate copyright notice;
+keep intact all notices stating that this License and any
+non-permissive terms added in accord with section 7 apply to the code;
+keep intact all notices of the absence of any warranty; and give all
+recipients a copy of this License along with the Program.
+
+  You may charge any price or no price for each copy that you convey,
+and you may offer support or warranty protection for a fee.
+
+  5. Conveying Modified Source Versions.
+
+  You may convey a work based on the Program, or the modifications to
+produce it from the Program, in the form of source code under the
+terms of section 4, provided that you also meet all of these conditions:
+
+    a) The work must carry prominent notices stating that you modified
+    it, and giving a relevant date.
+
+    b) The work must carry prominent notices stating that it is
+    released under this License and any conditions added under section
+    7.  This requirement modifies the requirement in section 4 to
+    "keep intact all notices".
+
+    c) You must license the entire work, as a whole, under this
+    License to anyone who comes into possession of a copy.  This
+    License will therefore apply, along with any applicable section 7
+    additional terms, to the whole of the work, and all its parts,
+    regardless of how they are packaged.  This License gives no
+    permission to license the work in any other way, but it does not
+    invalidate such permission if you have separately received it.
+
+    d) If the work has interactive user interfaces, each must display
+    Appropriate Legal Notices; however, if the Program has interactive
+    interfaces that do not display Appropriate Legal Notices, your
+    work need not make them do so.
+
+  A compilation of a covered work with other separate and independent
+works, which are not by their nature extensions of the covered work,
+and which are not combined with it such as to form a larger program,
+in or on a volume of a storage or distribution medium, is called an
+"aggregate" if the compilation and its resulting copyright are not
+used to limit the access or legal rights of the compilation's users
+beyond what the individual works permit.  Inclusion of a covered work
+in an aggregate does not cause this License to apply to the other
+parts of the aggregate.
+
+  6. Conveying Non-Source Forms.
+
+  You may convey a covered work in object code form under the terms
+of sections 4 and 5, provided that you also convey the
+machine-readable Corresponding Source under the terms of this License,
+in one of these ways:
+
+    a) Convey the object code in, or embodied in, a physical product
+    (including a physical distribution medium), accompanied by the
+    Corresponding Source fixed on a durable physical medium
+    customarily used for software interchange.
+
+    b) Convey the object code in, or embodied in, a physical product
+    (including a physical distribution medium), accompanied by a
+    written offer, valid for at least three years and valid for as
+    long as you offer spare parts or customer support for that product
+    model, to give anyone who possesses the object code either (1) a
+    copy of the Corresponding Source for all the software in the
+    product that is covered by this License, on a durable physical
+    medium customarily used for software interchange, for a price no
+    more than your reasonable cost of physically performing this
+    conveying of source, or (2) access to copy the
+    Corresponding Source from a network server at no charge.
+
+    c) Convey individual copies of the object code with a copy of the
+    written offer to provide the Corresponding Source.  This
+    alternative is allowed only occasionally and noncommercially, and
+    only if you received the object code with such an offer, in accord
+    with subsection 6b.
+
+    d) Convey the object code by offering access from a designated
+    place (gratis or for a charge), and offer equivalent access to the
+    Corresponding Source in the same way through the same place at no
+    further charge.  You need not require recipients to copy the
+    Corresponding Source along with the object code.  If the place to
+    copy the object code is a network server, the Corresponding Source
+    may be on a different server (operated by you or a third party)
+    that supports equivalent copying facilities, provided you maintain
+    clear directions next to the object code saying where to find the
+    Corresponding Source.  Regardless of what server hosts the
+    Corresponding Source, you remain obligated to ensure that it is
+    available for as long as needed to satisfy these requirements.
+
+    e) Convey the object code using peer-to-peer transmission, provided
+    you inform other peers where the object code and Corresponding
+    Source of the work are being offered to the general public at no
+    charge under subsection 6d.
+
+  A separable portion of the object code, whose source code is excluded
+from the Corresponding Source as a System Library, need not be
+included in conveying the object code work.
+
+  A "User Product" is either (1) a "consumer product", which means any
+tangible personal property which is normally used for personal, family,
+or household purposes, or (2) anything designed or sold for incorporation
+into a dwelling.  In determining whether a product is a consumer product,
+doubtful cases shall be resolved in favor of coverage.  For a particular
+product received by a particular user, "normally used" refers to a
+typical or common use of that class of product, regardless of the status
+of the particular user or of the way in which the particular user
+actually uses, or expects or is expected to use, the product.  A product
+is a consumer product regardless of whether the product has substantial
+commercial, industrial or non-consumer uses, unless such uses represent
+the only significant mode of use of the product.
+
+  "Installation Information" for a User Product means any methods,
+procedures, authorization keys, or other information required to install
+and execute modified versions of a covered work in that User Product from
+a modified version of its Corresponding Source.  The information must
+suffice to ensure that the continued functioning of the modified object
+code is in no case prevented or interfered with solely because
+modification has been made.
+
+  If you convey an object code work under this section in, or with, or
+specifically for use in, a User Product, and the conveying occurs as
+part of a transaction in which the right of possession and use of the
+User Product is transferred to the recipient in perpetuity or for a
+fixed term (regardless of how the transaction is characterized), the
+Corresponding Source conveyed under this section must be accompanied
+by the Installation Information.  But this requirement does not apply
+if neither you nor any third party retains the ability to install
+modified object code on the User Product (for example, the work has
+been installed in ROM).
+
+  The requirement to provide Installation Information does not include a
+requirement to continue to provide support service, warranty, or updates
+for a work that has been modified or installed by the recipient, or for
+the User Product in which it has been modified or installed.  Access to a
+network may be denied when the modification itself materially and
+adversely affects the operation of the network or violates the rules and
+protocols for communication across the network.
+
+  Corresponding Source conveyed, and Installation Information provided,
+in accord with this section must be in a format that is publicly
+documented (and with an implementation available to the public in
+source code form), and must require no special password or key for
+unpacking, reading or copying.
+
+  7. Additional Terms.
+
+  "Additional permissions" are terms that supplement the terms of this
+License by making exceptions from one or more of its conditions.
+Additional permissions that are applicable to the entire Program shall
+be treated as though they were included in this License, to the extent
+that they are valid under applicable law.  If additional permissions
+apply only to part of the Program, that part may be used separately
+under those permissions, but the entire Program remains governed by
+this License without regard to the additional permissions.
+
+  When you convey a copy of a covered work, you may at your option
+remove any additional permissions from that copy, or from any part of
+it.  (Additional permissions may be written to require their own
+removal in certain cases when you modify the work.)  You may place
+additional permissions on material, added by you to a covered work,
+for which you have or can give appropriate copyright permission.
+
+  Notwithstanding any other provision of this License, for material you
+add to a covered work, you may (if authorized by the copyright holders of
+that material) supplement the terms of this License with terms:
+
+    a) Disclaiming warranty or limiting liability differently from the
+    terms of sections 15 and 16 of this License; or
+
+    b) Requiring preservation of specified reasonable legal notices or
+    author attributions in that material or in the Appropriate Legal
+    Notices displayed by works containing it; or
+
+    c) Prohibiting misrepresentation of the origin of that material, or
+    requiring that modified versions of such material be marked in
+    reasonable ways as different from the original version; or
+
+    d) Limiting the use for publicity purposes of names of licensors or
+    authors of the material; or
+
+    e) Declining to grant rights under trademark law for use of some
+    trade names, trademarks, or service marks; or
+
+    f) Requiring indemnification of licensors and authors of that
+    material by anyone who conveys the material (or modified versions of
+    it) with contractual assumptions of liability to the recipient, for
+    any liability that these contractual assumptions directly impose on
+    those licensors and authors.
+
+  All other non-permissive additional terms are considered "further
+restrictions" within the meaning of section 10.  If the Program as you
+received it, or any part of it, contains a notice stating that it is
+governed by this License along with a term that is a further
+restriction, you may remove that term.  If a license document contains
+a further restriction but permits relicensing or conveying under this
+License, you may add to a covered work material governed by the terms
+of that license document, provided that the further restriction does
+not survive such relicensing or conveying.
+
+  If you add terms to a covered work in accord with this section, you
+must place, in the relevant source files, a statement of the
+additional terms that apply to those files, or a notice indicating
+where to find the applicable terms.
+
+  Additional terms, permissive or non-permissive, may be stated in the
+form of a separately written license, or stated as exceptions;
+the above requirements apply either way.
+
+  8. Termination.
+
+  You may not propagate or modify a covered work except as expressly
+provided under this License.  Any attempt otherwise to propagate or
+modify it is void, and will automatically terminate your rights under
+this License (including any patent licenses granted under the third
+paragraph of section 11).
+
+  However, if you cease all violation of this License, then your
+license from a particular copyright holder is reinstated (a)
+provisionally, unless and until the copyright holder explicitly and
+finally terminates your license, and (b) permanently, if the copyright
+holder fails to notify you of the violation by some reasonable means
+prior to 60 days after the cessation.
+
+  Moreover, your license from a particular copyright holder is
+reinstated permanently if the copyright holder notifies you of the
+violation by some reasonable means, this is the first time you have
+received notice of violation of this License (for any work) from that
+copyright holder, and you cure the violation prior to 30 days after
+your receipt of the notice.
+
+  Termination of your rights under this section does not terminate the
+licenses of parties who have received copies or rights from you under
+this License.  If your rights have been terminated and not permanently
+reinstated, you do not qualify to receive new licenses for the same
+material under section 10.
+
+  9. Acceptance Not Required for Having Copies.
+
+  You are not required to accept this License in order to receive or
+run a copy of the Program.  Ancillary propagation of a covered work
+occurring solely as a consequence of using peer-to-peer transmission
+to receive a copy likewise does not require acceptance.  However,
+nothing other than this License grants you permission to propagate or
+modify any covered work.  These actions infringe copyright if you do
+not accept this License.  Therefore, by modifying or propagating a
+covered work, you indicate your acceptance of this License to do so.
+
+  10. Automatic Licensing of Downstream Recipients.
+
+  Each time you convey a covered work, the recipient automatically
+receives a license from the original licensors, to run, modify and
+propagate that work, subject to this License.  You are not responsible
+for enforcing compliance by third parties with this License.
+
+  An "entity transaction" is a transaction transferring control of an
+organization, or substantially all assets of one, or subdividing an
+organization, or merging organizations.  If propagation of a covered
+work results from an entity transaction, each party to that
+transaction who receives a copy of the work also receives whatever
+licenses to the work the party's predecessor in interest had or could
+give under the previous paragraph, plus a right to possession of the
+Corresponding Source of the work from the predecessor in interest, if
+the predecessor has it or can get it with reasonable efforts.
+
+  You may not impose any further restrictions on the exercise of the
+rights granted or affirmed under this License.  For example, you may
+not impose a license fee, royalty, or other charge for exercise of
+rights granted under this License, and you may not initiate litigation
+(including a cross-claim or counterclaim in a lawsuit) alleging that
+any patent claim is infringed by making, using, selling, offering for
+sale, or importing the Program or any portion of it.
+
+  11. Patents.
+
+  A "contributor" is a copyright holder who authorizes use under this
+License of the Program or a work on which the Program is based.  The
+work thus licensed is called the contributor's "contributor version".
+
+  A contributor's "essential patent claims" are all patent claims
+owned or controlled by the contributor, whether already acquired or
+hereafter acquired, that would be infringed by some manner, permitted
+by this License, of making, using, or selling its contributor version,
+but do not include claims that would be infringed only as a
+consequence of further modification of the contributor version.  For
+purposes of this definition, "control" includes the right to grant
+patent sublicenses in a manner consistent with the requirements of
+this License.
+
+  Each contributor grants you a non-exclusive, worldwide, royalty-free
+patent license under the contributor's essential patent claims, to
+make, use, sell, offer for sale, import and otherwise run, modify and
+propagate the contents of its contributor version.
+
+  In the following three paragraphs, a "patent license" is any express
+agreement or commitment, however denominated, not to enforce a patent
+(such as an express permission to practice a patent or covenant not to
+sue for patent infringement).  To "grant" such a patent license to a
+party means to make such an agreement or commitment not to enforce a
+patent against the party.
+
+  If you convey a covered work, knowingly relying on a patent license,
+and the Corresponding Source of the work is not available for anyone
+to copy, free of charge and under the terms of this License, through a
+publicly available network server or other readily accessible means,
+then you must either (1) cause the Corresponding Source to be so
+available, or (2) arrange to deprive yourself of the benefit of the
+patent license for this particular work, or (3) arrange, in a manner
+consistent with the requirements of this License, to extend the patent
+license to downstream recipients.  "Knowingly relying" means you have
+actual knowledge that, but for the patent license, your conveying the
+covered work in a country, or your recipient's use of the covered work
+in a country, would infringe one or more identifiable patents in that
+country that you have reason to believe are valid.
+
+  If, pursuant to or in connection with a single transaction or
+arrangement, you convey, or propagate by procuring conveyance of, a
+covered work, and grant a patent license to some of the parties
+receiving the covered work authorizing them to use, propagate, modify
+or convey a specific copy of the covered work, then the patent license
+you grant is automatically extended to all recipients of the covered
+work and works based on it.
+
+  A patent license is "discriminatory" if it does not include within
+the scope of its coverage, prohibits the exercise of, or is
+conditioned on the non-exercise of one or more of the rights that are
+specifically granted under this License.  You may not convey a covered
+work if you are a party to an arrangement with a third party that is
+in the business of distributing software, under which you make payment
+to the third party based on the extent of your activity of conveying
+the work, and under which the third party grants, to any of the
+parties who would receive the covered work from you, a discriminatory
+patent license (a) in connection with copies of the covered work
+conveyed by you (or copies made from those copies), or (b) primarily
+for and in connection with specific products or compilations that
+contain the covered work, unless you entered into that arrangement,
+or that patent license was granted, prior to 28 March 2007.
+
+  Nothing in this License shall be construed as excluding or limiting
+any implied license or other defenses to infringement that may
+otherwise be available to you under applicable patent law.
+
+  12. No Surrender of Others' Freedom.
+
+  If conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License.  If you cannot convey a
+covered work so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you may
+not convey it at all.  For example, if you agree to terms that obligate you
+to collect a royalty for further conveying from those to whom you convey
+the Program, the only way you could satisfy both those terms and this
+License would be to refrain entirely from conveying the Program.
+
+  13. Use with the GNU Affero General Public License.
+
+  Notwithstanding any other provision of this License, you have
+permission to link or combine any covered work with a work licensed
+under version 3 of the GNU Affero General Public License into a single
+combined work, and to convey the resulting work.  The terms of this
+License will continue to apply to the part which is the covered work,
+but the special requirements of the GNU Affero General Public License,
+section 13, concerning interaction through a network will apply to the
+combination as such.
+
+  14. Revised Versions of this License.
+
+  The Free Software Foundation may publish revised and/or new versions of
+the GNU General Public License from time to time.  Such new versions will
+be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.
+
+  Each version is given a distinguishing version number.  If the
+Program specifies that a certain numbered version of the GNU General
+Public License "or any later version" applies to it, you have the
+option of following the terms and conditions either of that numbered
+version or of any later version published by the Free Software
+Foundation.  If the Program does not specify a version number of the
+GNU General Public License, you may choose any version ever published
+by the Free Software Foundation.
+
+  If the Program specifies that a proxy can decide which future
+versions of the GNU General Public License can be used, that proxy's
+public statement of acceptance of a version permanently authorizes you
+to choose that version for the Program.
+
+  Later license versions may give you additional or different
+permissions.  However, no additional obligations are imposed on any
+author or copyright holder as a result of your choosing to follow a
+later version.
+
+  15. Disclaimer of Warranty.
+
+  THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
+APPLICABLE LAW.  EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
+HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY
+OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
+THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
+PURPOSE.  THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM
+IS WITH YOU.  SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
+ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
+
+  16. Limitation of Liability.
+
+  IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
+THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
+GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE
+USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF
+DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
+PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),
+EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF
+SUCH DAMAGES.
+
+  17. Interpretation of Sections 15 and 16.
+
+  If the disclaimer of warranty and limitation of liability provided
+above cannot be given local legal effect according to their terms,
+reviewing courts shall apply local law that most closely approximates
+an absolute waiver of all civil liability in connection with the
+Program, unless a warranty or assumption of liability accompanies a
+copy of the Program in return for a fee.
+
+                     END OF TERMS AND CONDITIONS

+
+ Copyright (C) 2007 Free Software Foundation, Inc. <https://fsf.org/>
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+
+  This version of the GNU Lesser General Public License incorporates
+the terms and conditions of version 3 of the GNU General Public
+License, supplemented by the additional permissions listed below.
+
+  0. Additional Definitions.
+
+  As used herein, "this License" refers to version 3 of the GNU Lesser
+General Public License, and the "GNU GPL" refers to version 3 of the GNU
+General Public License.
+
+  "The Library" refers to a covered work governed by this License,
+other than an Application or a Combined Work as defined below.
+
+  An "Application" is any work that makes use of an interface provided
+by the Library, but which is not otherwise based on the Library.
+Defining a subclass of a class defined by the Library is deemed a mode
+of using an interface provided by the Library.
+
+  A "Combined Work" is a work produced by combining or linking an
+Application with the Library.  The particular version of the Library
+with which the Combined Work was made is also called the "Linked
+Version".
+
+  The "Minimal Corresponding Source" for a Combined Work means the
+Corresponding Source for the Combined Work, excluding any source code
+for portions of the Combined Work that, considered in isolation, are
+based on the Application, and not on the Linked Version.
+
+  The "Corresponding Application Code" for a Combined Work means the
+object code and/or source code for the Application, including any data
+and utility programs needed for reproducing the Combined Work from the
+Application, but excluding the System Libraries of the Combined Work.
+
+  1. Exception to Section 3 of the GNU GPL.
+
+  You may convey a covered work under sections 3 and 4 of this License
+without being bound by section 3 of the GNU GPL.
+
+  2. Conveying Modified Versions.
+
+  If you modify a copy of the Library, and, in your modifications, a
+facility refers to a function or data to be supplied by an Application
+that uses the facility (other than as an argument passed when the
+facility is invoked), then you may convey a copy of the modified
+version:
+
+   a) under this License, provided that you make a good faith effort to
+   ensure that, in the event an Application does not supply the
+   function or data, the facility still operates, and performs
+   whatever part of its purpose remains meaningful, or
+
+   b) under the GNU GPL, with none of the additional permissions of
+   this License applicable to that copy.
+
+  3. Object Code Incorporating Material from Library Header Files.
+
+  The object code form of an Application may incorporate material from
+a header file that is part of the Library.  You may convey such object
+code under terms of your choice, provided that, if the incorporated
+material is not limited to numerical parameters, data structure
+layouts and accessors, or small macros, inline functions and templates
+(ten or fewer lines in length), you do both of the following:
+
+   a) Give prominent notice with each copy of the object code that the
+   Library is used in it and that the Library and its use are
+   covered by this License.
+
+   b) Accompany the object code with a copy of the GNU GPL and this license
+   document.
+
+  4. Combined Works.
+
+  You may convey a Combined Work under terms of your choice that,
+taken together, effectively do not restrict modification of the
+portions of the Library contained in the Combined Work and reverse
+engineering for debugging such modifications, if you also do each of
+the following:
+
+   a) Give prominent notice with each copy of the Combined Work that
+   the Library is used in it and that the Library and its use are
+   covered by this License.
+
+   b) Accompany the Combined Work with a copy of the GNU GPL and this license
+   document.
+
+   c) For a Combined Work that displays copyright notices during
+   execution, include the copyright notice for the Library among
+   these notices, as well as a reference directing the user to the
+   copies of the GNU GPL and this license document.
+
+   d) Do one of the following:
+
+       0) Convey the Minimal Corresponding Source under the terms of this
+       License, and the Corresponding Application Code in a form
+       suitable for, and under terms that permit, the user to
+       recombine or relink the Application with a modified version of
+       the Linked Version to produce a modified Combined Work, in the
+       manner specified by section 6 of the GNU GPL for conveying
+       Corresponding Source.
+
+       1) Use a suitable shared library mechanism for linking with the
+       Library.  A suitable mechanism is one that (a) uses at run time
+       a copy of the Library already present on the user's computer
+       system, and (b) will operate properly with a modified version
+       of the Library that is interface-compatible with the Linked
+       Version.
+
+   e) Provide Installation Information, but only if you would otherwise
+   be required to provide such information under section 6 of the
+   GNU GPL, and only to the extent that such information is
+   necessary to install and execute a modified version of the
+   Combined Work produced by recombining or relinking the
+   Application with a modified version of the Linked Version. (If
+   you use option 4d0, the Installation Information must accompany
+   the Minimal Corresponding Source and Corresponding Application
+   Code. If you use option 4d1, you must provide the Installation
+   Information in the manner specified by section 6 of the GNU GPL
+   for conveying Corresponding Source.)
+
+  5. Combined Libraries.
+
+  You may place library facilities that are a work based on the
+Library side by side in a single library together with other library
+facilities that are not Applications and are not covered by this
+License, and convey such a combined library under terms of your
+choice, if you do both of the following:
+
+   a) Accompany the combined library with a copy of the same work based
+   on the Library, uncombined with any other library facilities,
+   conveyed under the terms of this License.
+
+   b) Give prominent notice with the combined library that part of it
+   is a work based on the Library, and explaining where to find the
+   accompanying uncombined form of the same work.
+
+  6. Revised Versions of the GNU Lesser General Public License.
+
+  The Free Software Foundation may publish revised and/or new versions
+of the GNU Lesser General Public License from time to time. Such new
+versions will be similar in spirit to the present version, but may
+differ in detail to address new problems or concerns.
+
+  Each version is given a distinguishing version number. If the
+Library as you received it specifies that a certain numbered version
+of the GNU Lesser General Public License "or any later version"
+applies to it, you have the option of following the terms and
+conditions either of that published version or of any later version
+published by the Free Software Foundation. If the Library as you
+received it does not specify a version number of the GNU Lesser
+General Public License, you may choose any version of the GNU Lesser
+General Public License ever published by the Free Software Foundation.
+
+  If the Library as you received it specifies that a proxy can decide
+whether future versions of the GNU Lesser General Public License shall
+apply, that proxy's public statement of acceptance of any version is
+permanent authorization for you to choose that version for the
+Library.

+                    GNU GENERAL PUBLIC LICENSE
+                       Version 3, 29 June 2007
+
+ Copyright (C) 2007 Free Software Foundation, Inc. <https://fsf.org/>
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+                            Preamble
+
+  The GNU General Public License is a free, copyleft license for
+software and other kinds of works.
+
+  The licenses for most software and other practical works are designed
+to take away your freedom to share and change the works.  By contrast,
+the GNU General Public License is intended to guarantee your freedom to
+share and change all versions of a program--to make sure it remains free
+software for all its users.  We, the Free Software Foundation, use the
+GNU General Public License for most of our software; it applies also to
+any other work released this way by its authors.  You can apply it to
+your programs, too.
+
+  When we speak of free software, we are referring to freedom, not
+price.  Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+them if you wish), that you receive source code or can get it if you
+want it, that you can change the software or use pieces of it in new
+free programs, and that you know you can do these things.
+
+  To protect your rights, we need to prevent others from denying you
+these rights or asking you to surrender the rights.  Therefore, you have
+certain responsibilities if you distribute copies of the software, or if
+you modify it: responsibilities to respect the freedom of others.
+
+  For example, if you distribute copies of such a program, whether
+gratis or for a fee, you must pass on to the recipients the same
+freedoms that you received.  You must make sure that they, too, receive
+or can get the source code.  And you must show them these terms so they
+know their rights.
+
+  Developers that use the GNU GPL protect your rights with two steps:
+(1) assert copyright on the software, and (2) offer you this License
+giving you legal permission to copy, distribute and/or modify it.
+
+  For the developers' and authors' protection, the GPL clearly explains
+that there is no warranty for this free software.  For both users' and
+authors' sake, the GPL requires that modified versions be marked as
+changed, so that their problems will not be attributed erroneously to
+authors of previous versions.
+
+  Some devices are designed to deny users access to install or run
+modified versions of the software inside them, although the manufacturer
+can do so.  This is fundamentally incompatible with the aim of
+protecting users' freedom to change the software.  The systematic
+pattern of such abuse occurs in the area of products for individuals to
+use, which is precisely where it is most unacceptable.  Therefore, we
+have designed this version of the GPL to prohibit the practice for those
+products.  If such problems arise substantially in other domains, we
+stand ready to extend this provision to those domains in future versions
+of the GPL, as needed to protect the freedom of users.
+
+  Finally, every program is threatened constantly by software patents.
+States should not allow patents to restrict development and use of
+software on general-purpose computers, but in those that do, we wish to
+avoid the special danger that patents applied to a free program could
+make it effectively proprietary.  To prevent this, the GPL assures that
+patents cannot be used to render the program non-free.
+
+  The precise terms and conditions for copying, distribution and
+modification follow.
+
+                       TERMS AND CONDITIONS
+
+  0. Definitions.
+
+  "This License" refers to version 3 of the GNU General Public License.
+
+  "Copyright" also means copyright-like laws that apply to other kinds of
+works, such as semiconductor masks.
+
+  "The Program" refers to any copyrightable work licensed under this
+License.  Each licensee is addressed as "you".  "Licensees" and
+"recipients" may be individuals or organizations.
+
+  To "modify" a work means to copy from or adapt all or part of the work
+in a fashion requiring copyright permission, other than the making of an
+exact copy.  The resulting work is called a "modified version" of the
+earlier work or a work "based on" the earlier work.
+
+  A "covered work" means either the unmodified Program or a work based
+on the Program.
+
+  To "propagate" a work means to do anything with it that, without
+permission, would make you directly or secondarily liable for
+infringement under applicable copyright law, except executing it on a
+computer or modifying a private copy.  Propagation includes copying,
+distribution (with or without modification), making available to the
+public, and in some countries other activities as well.
+
+  To "convey" a work means any kind of propagation that enables other
+parties to make or receive copies.  Mere interaction with a user through
+a computer network, with no transfer of a copy, is not conveying.
+
+  An interactive user interface displays "Appropriate Legal Notices"
+to the extent that it includes a convenient and prominently visible
+feature that (1) displays an appropriate copyright notice, and (2)
+tells the user that there is no warranty for the work (except to the
+extent that warranties are provided), that licensees may convey the
+work under this License, and how to view a copy of this License.  If
+the interface presents a list of user commands or options, such as a
+menu, a prominent item in the list meets this criterion.
+
+  1. Source Code.
+
+  The "source code" for a work means the preferred form of the work
+for making modifications to it.  "Object code" means any non-source
+form of a work.
+
+  A "Standard Interface" means an interface that either is an official
+standard defined by a recognized standards body, or, in the case of
+interfaces specified for a particular programming language, one that
+is widely used among developers working in that language.
+
+  The "System Libraries" of an executable work include anything, other
+than the work as a whole, that (a) is included in the normal form of
+packaging a Major Component, but which is not part of that Major
+Component, and (b) serves only to enable use of the work with that
+Major Component, or to implement a Standard Interface for which an
+implementation is available to the public in source code form.  A
+"Major Component", in this context, means a major essential component
+(kernel, window system, and so on) of the specific operating system
+(if any) on which the executable work runs, or a compiler used to
+produce the work, or an object code interpreter used to run it.
+
+  The "Corresponding Source" for a work in object code form means all
+the source code needed to generate, install, and (for an executable
+work) run the object code and to modify the work, including scripts to
+control those activities.  However, it does not include the work's
+System Libraries, or general-purpose tools or generally available free
+programs which are used unmodified in performing those activities but
+which are not part of the work.  For example, Corresponding Source
+includes interface definition files associated with source files for
+the work, and the source code for shared libraries and dynamically
+linked subprograms that the work is specifically designed to require,
+such as by intimate data communication or control flow between those
+subprograms and other parts of the work.
+
+  The Corresponding Source need not include anything that users
+can regenerate automatically from other parts of the Corresponding
+Source.
+
+  The Corresponding Source for a work in source code form is that
+same work.
+
+  2. Basic Permissions.
+
+  All rights granted under this License are granted for the term of
+copyright on the Program, and are irrevocable provided the stated
+conditions are met.  This License explicitly affirms your unlimited
+permission to run the unmodified Program.  The output from running a
+covered work is covered by this License only if the output, given its
+content, constitutes a covered work.  This License acknowledges your
+rights of fair use or other equivalent, as provided by copyright law.
+
+  You may make, run and propagate covered works that you do not
+convey, without conditions so long as your license otherwise remains
+in force.  You may convey covered works to others for the sole purpose
+of having them make modifications exclusively for you, or provide you
+with facilities for running those works, provided that you comply with
+the terms of this License in conveying all material for which you do
+not control copyright.  Those thus making or running the covered works
+for you must do so exclusively on your behalf, under your direction
+and control, on terms that prohibit them from making any copies of
+your copyrighted material outside their relationship with you.
+
+  Conveying under any other circumstances is permitted solely under
+the conditions stated below.  Sublicensing is not allowed; section 10
+makes it unnecessary.
+
+  3. Protecting Users' Legal Rights From Anti-Circumvention Law.
+
+  No covered work shall be deemed part of an effective technological
+measure under any applicable law fulfilling obligations under article
+11 of the WIPO copyright treaty adopted on 20 December 1996, or
+similar laws prohibiting or restricting circumvention of such
+measures.
+
+  When you convey a covered work, you waive any legal power to forbid
+circumvention of technological measures to the extent such circumvention
+is effected by exercising rights under this License with respect to
+the covered work, and you disclaim any intention to limit operation or
+modification of the work as a means of enforcing, against the work's
+users, your or third parties' legal rights to forbid circumvention of
+technological measures.
+
+  4. Conveying Verbatim Copies.
+
+  You may convey verbatim copies of the Program's source code as you
+receive it, in any medium, provided that you conspicuously and
+appropriately publish on each copy an appropriate copyright notice;
+keep intact all notices stating that this License and any
+non-permissive terms added in accord with section 7 apply to the code;
+keep intact all notices of the absence of any warranty; and give all
+recipients a copy of this License along with the Program.
+
+  You may charge any price or no price for each copy that you convey,
+and you may offer support or warranty protection for a fee.
+
+  5. Conveying Modified Source Versions.
+
+  You may convey a work based on the Program, or the modifications to
+produce it from the Program, in the form of source code under the
+terms of section 4, provided that you also meet all of these conditions:
+
+    a) The work must carry prominent notices stating that you modified
+    it, and giving a relevant date.
+
+    b) The work must carry prominent notices stating that it is
+    released under this License and any conditions added under section
+    7.  This requirement modifies the requirement in section 4 to
+    "keep intact all notices".
+
+    c) You must license the entire work, as a whole, under this
+    License to anyone who comes into possession of a copy.  This
+    License will therefore apply, along with any applicable section 7
+    additional terms, to the whole of the work, and all its parts,
+    regardless of how they are packaged.  This License gives no
+    permission to license the work in any other way, but it does not
+    invalidate such permission if you have separately received it.
+
+    d) If the work has interactive user interfaces, each must display
+    Appropriate Legal Notices; however, if the Program has interactive
+    interfaces that do not display Appropriate Legal Notices, your
+    work need not make them do so.
+
+  A compilation of a covered work with other separate and independent
+works, which are not by their nature extensions of the covered work,
+and which are not combined with it such as to form a larger program,
+in or on a volume of a storage or distribution medium, is called an
+"aggregate" if the compilation and its resulting copyright are not
+used to limit the access or legal rights of the compilation's users
+beyond what the individual works permit.  Inclusion of a covered work
+in an aggregate does not cause this License to apply to the other
+parts of the aggregate.
+
+  6. Conveying Non-Source Forms.
+
+  You may convey a covered work in object code form under the terms
+of sections 4 and 5, provided that you also convey the
+machine-readable Corresponding Source under the terms of this License,
+in one of these ways:
+
+    a) Convey the object code in, or embodied in, a physical product
+    (including a physical distribution medium), accompanied by the
+    Corresponding Source fixed on a durable physical medium
+    customarily used for software interchange.
+
+    b) Convey the object code in, or embodied in, a physical product
+    (including a physical distribution medium), accompanied by a
+    written offer, valid for at least three years and valid for as
+    long as you offer spare parts or customer support for that product
+    model, to give anyone who possesses the object code either (1) a
+    copy of the Corresponding Source for all the software in the
+    product that is covered by this License, on a durable physical
+    medium customarily used for software interchange, for a price no
+    more than your reasonable cost of physically performing this
+    conveying of source, or (2) access to copy the
+    Corresponding Source from a network server at no charge.
+
+    c) Convey individual copies of the object code with a copy of the
+    written offer to provide the Corresponding Source.  This
+    alternative is allowed only occasionally and noncommercially, and
+    only if you received the object code with such an offer, in accord
+    with subsection 6b.
+
+    d) Convey the object code by offering access from a designated
+    place (gratis or for a charge), and offer equivalent access to the
+    Corresponding Source in the same way through the same place at no
+    further charge.  You need not require recipients to copy the
+    Corresponding Source along with the object code.  If the place to
+    copy the object code is a network server, the Corresponding Source
+    may be on a different server (operated by you or a third party)
+    that supports equivalent copying facilities, provided you maintain
+    clear directions next to the object code saying where to find the
+    Corresponding Source.  Regardless of what server hosts the
+    Corresponding Source, you remain obligated to ensure that it is
+    available for as long as needed to satisfy these requirements.
+
+    e) Convey the object code using peer-to-peer transmission, provided
+    you inform other peers where the object code and Corresponding
+    Source of the work are being offered to the general public at no
+    charge under subsection 6d.
+
+  A separable portion of the object code, whose source code is excluded
+from the Corresponding Source as a System Library, need not be
+included in conveying the object code work.
+
+  A "User Product" is either (1) a "consumer product", which means any
+tangible personal property which is normally used for personal, family,
+or household purposes, or (2) anything designed or sold for incorporation
+into a dwelling.  In determining whether a product is a consumer product,
+doubtful cases shall be resolved in favor of coverage.  For a particular
+product received by a particular user, "normally used" refers to a
+typical or common use of that class of product, regardless of the status
+of the particular user or of the way in which the particular user
+actually uses, or expects or is expected to use, the product.  A product
+is a consumer product regardless of whether the product has substantial
+commercial, industrial or non-consumer uses, unless such uses represent
+the only significant mode of use of the product.
+
+  "Installation Information" for a User Product means any methods,
+procedures, authorization keys, or other information required to install
+and execute modified versions of a covered work in that User Product from
+a modified version of its Corresponding Source.  The information must
+suffice to ensure that the continued functioning of the modified object
+code is in no case prevented or interfered with solely because
+modification has been made.
+
+  If you convey an object code work under this section in, or with, or
+specifically for use in, a User Product, and the conveying occurs as
+part of a transaction in which the right of possession and use of the
+User Product is transferred to the recipient in perpetuity or for a
+fixed term (regardless of how the transaction is characterized), the
+Corresponding Source conveyed under this section must be accompanied
+by the Installation Information.  But this requirement does not apply
+if neither you nor any third party retains the ability to install
+modified object code on the User Product (for example, the work has
+been installed in ROM).
+
+  The requirement to provide Installation Information does not include a
+requirement to continue to provide support service, warranty, or updates
+for a work that has been modified or installed by the recipient, or for
+the User Product in which it has been modified or installed.  Access to a
+network may be denied when the modification itself materially and
+adversely affects the operation of the network or violates the rules and
+protocols for communication across the network.
+
+  Corresponding Source conveyed, and Installation Information provided,
+in accord with this section must be in a format that is publicly
+documented (and with an implementation available to the public in
+source code form), and must require no special password or key for
+unpacking, reading or copying.
+
+  7. Additional Terms.
+
+  "Additional permissions" are terms that supplement the terms of this
+License by making exceptions from one or more of its conditions.
+Additional permissions that are applicable to the entire Program shall
+be treated as though they were included in this License, to the extent
+that they are valid under applicable law.  If additional permissions
+apply only to part of the Program, that part may be used separately
+under those permissions, but the entire Program remains governed by
+this License without regard to the additional permissions.
+
+  When you convey a copy of a covered work, you may at your option
+remove any additional permissions from that copy, or from any part of
+it.  (Additional permissions may be written to require their own
+removal in certain cases when you modify the work.)  You may place
+additional permissions on material, added by you to a covered work,
+for which you have or can give appropriate copyright permission.
+
+  Notwithstanding any other provision of this License, for material you
+add to a covered work, you may (if authorized by the copyright holders of
+that material) supplement the terms of this License with terms:
+
+    a) Disclaiming warranty or limiting liability differently from the
+    terms of sections 15 and 16 of this License; or
+
+    b) Requiring preservation of specified reasonable legal notices or
+    author attributions in that material or in the Appropriate Legal
+    Notices displayed by works containing it; or
+
+    c) Prohibiting misrepresentation of the origin of that material, or
+    requiring that modified versions of such material be marked in
+    reasonable ways as different from the original version; or
+
+    d) Limiting the use for publicity purposes of names of licensors or
+    authors of the material; or
+
+    e) Declining to grant rights under trademark law for use of some
+    trade names, trademarks, or service marks; or
+
+    f) Requiring indemnification of licensors and authors of that
+    material by anyone who conveys the material (or modified versions of
+    it) with contractual assumptions of liability to the recipient, for
+    any liability that these contractual assumptions directly impose on
+    those licensors and authors.
+
+  All other non-permissive additional terms are considered "further
+restrictions" within the meaning of section 10.  If the Program as you
+received it, or any part of it, contains a notice stating that it is
+governed by this License along with a term that is a further
+restriction, you may remove that term.  If a license document contains
+a further restriction but permits relicensing or conveying under this
+License, you may add to a covered work material governed by the terms
+of that license document, provided that the further restriction does
+not survive such relicensing or conveying.
+
+  If you add terms to a covered work in accord with this section, you
+must place, in the relevant source files, a statement of the
+additional terms that apply to those files, or a notice indicating
+where to find the applicable terms.
+
+  Additional terms, permissive or non-permissive, may be stated in the
+form of a separately written license, or stated as exceptions;
+the above requirements apply either way.
+
+  8. Termination.
+
+  You may not propagate or modify a covered work except as expressly
+provided under this License.  Any attempt otherwise to propagate or
+modify it is void, and will automatically terminate your rights under
+this License (including any patent licenses granted under the third
+paragraph of section 11).
+
+  However, if you cease all violation of this License, then your
+license from a particular copyright holder is reinstated (a)
+provisionally, unless and until the copyright holder explicitly and
+finally terminates your license, and (b) permanently, if the copyright
+holder fails to notify you of the violation by some reasonable means
+prior to 60 days after the cessation.
+
+  Moreover, your license from a particular copyright holder is
+reinstated permanently if the copyright holder notifies you of the
+violation by some reasonable means, this is the first time you have
+received notice of violation of this License (for any work) from that
+copyright holder, and you cure the violation prior to 30 days after
+your receipt of the notice.
+
+  Termination of your rights under this section does not terminate the
+licenses of parties who have received copies or rights from you under
+this License.  If your rights have been terminated and not permanently
+reinstated, you do not qualify to receive new licenses for the same
+material under section 10.
+
+  9. Acceptance Not Required for Having Copies.
+
+  You are not required to accept this License in order to receive or
+run a copy of the Program.  Ancillary propagation of a covered work
+occurring solely as a consequence of using peer-to-peer transmission
+to receive a copy likewise does not require acceptance.  However,
+nothing other than this License grants you permission to propagate or
+modify any covered work.  These actions infringe copyright if you do
+not accept this License.  Therefore, by modifying or propagating a
+covered work, you indicate your acceptance of this License to do so.
+
+  10. Automatic Licensing of Downstream Recipients.
+
+  Each time you convey a covered work, the recipient automatically
+receives a license from the original licensors, to run, modify and
+propagate that work, subject to this License.  You are not responsible
+for enforcing compliance by third parties with this License.
+
+  An "entity transaction" is a transaction transferring control of an
+organization, or substantially all assets of one, or subdividing an
+organization, or merging organizations.  If propagation of a covered
+work results from an entity transaction, each party to that
+transaction who receives a copy of the work also receives whatever
+licenses to the work the party's predecessor in interest had or could
+give under the previous paragraph, plus a right to possession of the
+Corresponding Source of the work from the predecessor in interest, if
+the predecessor has it or can get it with reasonable efforts.
+
+  You may not impose any further restrictions on the exercise of the
+rights granted or affirmed under this License.  For example, you may
+not impose a license fee, royalty, or other charge for exercise of
+rights granted under this License, and you may not initiate litigation
+(including a cross-claim or counterclaim in a lawsuit) alleging that
+any patent claim is infringed by making, using, selling, offering for
+sale, or importing the Program or any portion of it.
+
+  11. Patents.
+
+  A "contributor" is a copyright holder who authorizes use under this
+License of the Program or a work on which the Program is based.  The
+work thus licensed is called the contributor's "contributor version".
+
+  A contributor's "essential patent claims" are all patent claims
+owned or controlled by the contributor, whether already acquired or
+hereafter acquired, that would be infringed by some manner, permitted
+by this License, of making, using, or selling its contributor version,
+but do not include claims that would be infringed only as a
+consequence of further modification of the contributor version.  For
+purposes of this definition, "control" includes the right to grant
+patent sublicenses in a manner consistent with the requirements of
+this License.
+
+  Each contributor grants you a non-exclusive, worldwide, royalty-free
+patent license under the contributor's essential patent claims, to
+make, use, sell, offer for sale, import and otherwise run, modify and
+propagate the contents of its contributor version.
+
+  In the following three paragraphs, a "patent license" is any express
+agreement or commitment, however denominated, not to enforce a patent
+(such as an express permission to practice a patent or covenant not to
+sue for patent infringement).  To "grant" such a patent license to a
+party means to make such an agreement or commitment not to enforce a
+patent against the party.
+
+  If you convey a covered work, knowingly relying on a patent license,
+and the Corresponding Source of the work is not available for anyone
+to copy, free of charge and under the terms of this License, through a
+publicly available network server or other readily accessible means,
+then you must either (1) cause the Corresponding Source to be so
+available, or (2) arrange to deprive yourself of the benefit of the
+patent license for this particular work, or (3) arrange, in a manner
+consistent with the requirements of this License, to extend the patent
+license to downstream recipients.  "Knowingly relying" means you have
+actual knowledge that, but for the patent license, your conveying the
+covered work in a country, or your recipient's use of the covered work
+in a country, would infringe one or more identifiable patents in that
+country that you have reason to believe are valid.
+
+  If, pursuant to or in connection with a single transaction or
+arrangement, you convey, or propagate by procuring conveyance of, a
+covered work, and grant a patent license to some of the parties
+receiving the covered work authorizing them to use, propagate, modify
+or convey a specific copy of the covered work, then the patent license
+you grant is automatically extended to all recipients of the covered
+work and works based on it.
+
+  A patent license is "discriminatory" if it does not include within
+the scope of its coverage, prohibits the exercise of, or is
+conditioned on the non-exercise of one or more of the rights that are
+specifically granted under this License.  You may not convey a covered
+work if you are a party to an arrangement with a third party that is
+in the business of distributing software, under which you make payment
+to the third party based on the extent of your activity of conveying
+the work, and under which the third party grants, to any of the
+parties who would receive the covered work from you, a discriminatory
+patent license (a) in connection with copies of the covered work
+conveyed by you (or copies made from those copies), or (b) primarily
+for and in connection with specific products or compilations that
+contain the covered work, unless you entered into that arrangement,
+or that patent license was granted, prior to 28 March 2007.
+
+  Nothing in this License shall be construed as excluding or limiting
+any implied license or other defenses to infringement that may
+otherwise be available to you under applicable patent law.
+
+  12. No Surrender of Others' Freedom.
+
+  If conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License.  If you cannot convey a
+covered work so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you may
+not convey it at all.  For example, if you agree to terms that obligate you
+to collect a royalty for further conveying from those to whom you convey
+the Program, the only way you could satisfy both those terms and this
+License would be to refrain entirely from conveying the Program.
+
+  13. Use with the GNU Affero General Public License.
+
+  Notwithstanding any other provision of this License, you have
+permission to link or combine any covered work with a work licensed
+under version 3 of the GNU Affero General Public License into a single
+combined work, and to convey the resulting work.  The terms of this
+License will continue to apply to the part which is the covered work,
+but the special requirements of the GNU Affero General Public License,
+section 13, concerning interaction through a network will apply to the
+combination as such.
+
+  14. Revised Versions of this License.
+
+  The Free Software Foundation may publish revised and/or new versions of
+the GNU General Public License from time to time.  Such new versions will
+be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.
+
+  Each version is given a distinguishing version number.  If the
+Program specifies that a certain numbered version of the GNU General
+Public License "or any later version" applies to it, you have the
+option of following the terms and conditions either of that numbered
+version or of any later version published by the Free Software
+Foundation.  If the Program does not specify a version number of the
+GNU General Public License, you may choose any version ever published
+by the Free Software Foundation.
+
+  If the Program specifies that a proxy can decide which future
+versions of the GNU General Public License can be used, that proxy's
+public statement of acceptance of a version permanently authorizes you
+to choose that version for the Program.
+
+  Later license versions may give you additional or different
+permissions.  However, no additional obligations are imposed on any
+author or copyright holder as a result of your choosing to follow a
+later version.
+
+  15. Disclaimer of Warranty.
+
+  THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
+APPLICABLE LAW.  EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
+HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY
+OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
+THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
+PURPOSE.  THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM
+IS WITH YOU.  SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
+ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
+
+  16. Limitation of Liability.
+
+  IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
+THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
+GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE
+USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF
+DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
+PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),
+EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF
+SUCH DAMAGES.
+
+  17. Interpretation of Sections 15 and 16.
+
+  If the disclaimer of warranty and limitation of liability provided
+above cannot be given local legal effect according to their terms,
+reviewing courts shall apply local law that most closely approximates
+an absolute waiver of all civil liability in connection with the
+Program, unless a warranty or assumption of liability accompanies a
+copy of the Program in return for a fee.
+
+                     END OF TERMS AND CONDITIONS

+
+ Copyright (C) 2007 Free Software Foundation, Inc. <https://fsf.org/>
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+
+  This version of the GNU Lesser General Public License incorporates
+the terms and conditions of version 3 of the GNU General Public
+License, supplemented by the additional permissions listed below.
+
+  0. Additional Definitions.
+
+  As used herein, "this License" refers to version 3 of the GNU Lesser
+General Public License, and the "GNU GPL" refers to version 3 of the GNU
+General Public License.
+
+  "The Library" refers to a covered work governed by this License,
+other than an Application or a Combined Work as defined below.
+
+  An "Application" is any work that makes use of an interface provided
+by the Library, but which is not otherwise based on the Library.
+Defining a subclass of a class defined by the Library is deemed a mode
+of using an interface provided by the Library.
+
+  A "Combined Work" is a work produced by combining or linking an
+Application with the Library.  The particular version of the Library
+with which the Combined Work was made is also called the "Linked
+Version".
+
+  The "Minimal Corresponding Source" for a Combined Work means the
+Corresponding Source for the Combined Work, excluding any source code
+for portions of the Combined Work that, considered in isolation, are
+based on the Application, and not on the Linked Version.
+
+  The "Corresponding Application Code" for a Combined Work means the
+object code and/or source code for the Application, including any data
+and utility programs needed for reproducing the Combined Work from the
+Application, but excluding the System Libraries of the Combined Work.
+
+  1. Exception to Section 3 of the GNU GPL.
+
+  You may convey a covered work under sections 3 and 4 of this License
+without being bound by section 3 of the GNU GPL.
+
+  2. Conveying Modified Versions.
+
+  If you modify a copy of the Library, and, in your modifications, a
+facility refers to a function or data to be supplied by an Application
+that uses the facility (other than as an argument passed when the
+facility is invoked), then you may convey a copy of the modified
+version:
+
+   a) under this License, provided that you make a good faith effort to
+   ensure that, in the event an Application does not supply the
+   function or data, the facility still operates, and performs
+   whatever part of its purpose remains meaningful, or
+
+   b) under the GNU GPL, with none of the additional permissions of
+   this License applicable to that copy.
+
+  3. Object Code Incorporating Material from Library Header Files.
+
+  The object code form of an Application may incorporate material from
+a header file that is part of the Library.  You may convey such object
+code under terms of your choice, provided that, if the incorporated
+material is not limited to numerical parameters, data structure
+layouts and accessors, or small macros, inline functions and templates
+(ten or fewer lines in length), you do both of the following:
+
+   a) Give prominent notice with each copy of the object code that the
+   Library is used in it and that the Library and its use are
+   covered by this License.
+
+   b) Accompany the object code with a copy of the GNU GPL and this license
+   document.
+
+  4. Combined Works.
+
+  You may convey a Combined Work under terms of your choice that,
+taken together, effectively do not restrict modification of the
+portions of the Library contained in the Combined Work and reverse
+engineering for debugging such modifications, if you also do each of
+the following:
+
+   a) Give prominent notice with each copy of the Combined Work that
+   the Library is used in it and that the Library and its use are
+   covered by this License.
+
+   b) Accompany the Combined Work with a copy of the GNU GPL and this license
+   document.
+
+   c) For a Combined Work that displays copyright notices during
+   execution, include the copyright notice for the Library among
+   these notices, as well as a reference directing the user to the
+   copies of the GNU GPL and this license document.
+
+   d) Do one of the following:
+
+       0) Convey the Minimal Corresponding Source under the terms of this
+       License, and the Corresponding Application Code in a form
+       suitable for, and under terms that permit, the user to
+       recombine or relink the Application with a modified version of
+       the Linked Version to produce a modified Combined Work, in the
+       manner specified by section 6 of the GNU GPL for conveying
+       Corresponding Source.
+
+       1) Use a suitable shared library mechanism for linking with the
+       Library.  A suitable mechanism is one that (a) uses at run time
+       a copy of the Library already present on the user's computer
+       system, and (b) will operate properly with a modified version
+       of the Library that is interface-compatible with the Linked
+       Version.
+
+   e) Provide Installation Information, but only if you would otherwise
+   be required to provide such information under section 6 of the
+   GNU GPL, and only to the extent that such information is
+   necessary to install and execute a modified version of the
+   Combined Work produced by recombining or relinking the
+   Application with a modified version of the Linked Version. (If
+   you use option 4d0, the Installation Information must accompany
+   the Minimal Corresponding Source and Corresponding Application
+   Code. If you use option 4d1, you must provide the Installation
+   Information in the manner specified by section 6 of the GNU GPL
+   for conveying Corresponding Source.)
+
+  5. Combined Libraries.
+
+  You may place library facilities that are a work based on the
+Library side by side in a single library together with other library
+facilities that are not Applications and are not covered by this
+License, and convey such a combined library under terms of your
+choice, if you do both of the following:
+
+   a) Accompany the combined library with a copy of the same work based
+   on the Library, uncombined with any other library facilities,
+   conveyed under the terms of this License.
+
+   b) Give prominent notice with the combined library that part of it
+   is a work based on the Library, and explaining where to find the
+   accompanying uncombined form of the same work.
+
+  6. Revised Versions of the GNU Lesser General Public License.
+
+  The Free Software Foundation may publish revised and/or new versions
+of the GNU Lesser General Public License from time to time. Such new
+versions will be similar in spirit to the present version, but may
+differ in detail to address new problems or concerns.
+
+  Each version is given a distinguishing version number. If the
+Library as you received it specifies that a certain numbered version
+of the GNU Lesser General Public License "or any later version"
+applies to it, you have the option of following the terms and
+conditions either of that published version or of any later version
+published by the Free Software Foundation. If the Library as you
+received it does not specify a version number of the GNU Lesser
+General Public License, you may choose any version of the GNU Lesser
+General Public License ever published by the Free Software Foundation.
+
+  If the Library as you received it specifies that a proxy can decide
+whether future versions of the GNU Lesser General Public License shall
+apply, that proxy's public statement of acceptance of any version is
+permanent authorization for you to choose that version for the
+Library.

+price.  Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+them if you wish), that you receive source code or can get it if you
+want it, that you can change the software or use pieces of it in new
+free programs, and that you know you can do these things.
+
+  To protect your rights, we need to prevent others from denying you
+these rights or asking you to surrender the rights.  Therefore, you have
+certain responsibilities if you distribute copies of the software, or if
+you modify it: responsibilities to respect the freedom of others.
+
+  For example, if you distribute copies of such a program, whether
+gratis or for a fee, you must pass on to the recipients the same
+freedoms that you received.  You must make sure that they, too, receive
+or can get the source code.  And you must show them these terms so they
+know their rights.
+
+  Developers that use the GNU GPL protect your rights with two steps:
+(1) assert copyright on the software, and (2) offer you this License
+giving you legal permission to copy, distribute and/or modify it.
+
+  For the developers' and authors' protection, the GPL clearly explains
+that there is no warranty for this free software.  For both users' and
+authors' sake, the GPL requires that modified versions be marked as
+changed, so that their problems will not be attributed erroneously to
+authors of previous versions.
+
+  Some devices are designed to deny users access to install or run
+modified versions of the software inside them, although the manufacturer
+can do so.  This is fundamentally incompatible with the aim of
+protecting users' freedom to change the software.  The systematic
+pattern of such abuse occurs in the area of products for individuals to
+use, which is precisely where it is most unacceptable.  Therefore, we
+have designed this version of the GPL to prohibit the practice for those
+products.  If such problems arise substantially in other domains, we
+stand ready to extend this provision to those domains in future versions
+of the GPL, as needed to protect the freedom of users.
+
+  Finally, every program is threatened constantly by software patents.
+States should not allow patents to restrict development and use of
+software on general-purpose computers, but in those that do, we wish to
+avoid the special danger that patents applied to a free program could
+make it effectively proprietary.  To prevent this, the GPL assures that
+patents cannot be used to render the program non-free.
+
+  The precise terms and conditions for copying, distribution and
+modification follow.
+
+                       TERMS AND CONDITIONS
+
+  0. Definitions.
+
+  "This License" refers to version 3 of the GNU General Public License.
+
+  "Copyright" also means copyright-like laws that apply to other kinds of
+works, such as semiconductor masks.
+
+  "The Program" refers to any copyrightable work licensed under this
+License.  Each licensee is addressed as "you".  "Licensees" and
+"recipients" may be individuals or organizations.
+
+  To "modify" a work means to copy from or adapt all or part of the work
+in a fashion requiring copyright permission, other than the making of an
+exact copy.  The resulting work is called a "modified version" of the
+earlier work or a work "based on" the earlier work.
+
+  A "covered work" means either the unmodified Program or a work based
+on the Program.
+
+  To "propagate" a work means to do anything with it that, without
+permission, would make you directly or secondarily liable for
+infringement under applicable copyright law, except executing it on a
+computer or modifying a private copy.  Propagation includes copying,
+distribution (with or without modification), making available to the
+public, and in some countries other activities as well.
+
+  To "convey" a work means any kind of propagation that enables other
+parties to make or receive copies.  Mere interaction with a user through
+a computer network, with no transfer of a copy, is not conveying.
+
+  An interactive user interface displays "Appropriate Legal Notices"
+to the extent that it includes a convenient and prominently visible
+feature that (1) displays an appropriate copyright notice, and (2)
+tells the user that there is no warranty for the work (except to the
+extent that warranties are provided), that licensees may convey the
+work under this License, and how to view a copy of this License.  If
+the interface presents a list of user commands or options, such as a
+menu, a prominent item in the list meets this criterion.
+
+  1. Source Code.
+
+  The "source code" for a work means the preferred form of the work
+for making modifications to it.  "Object code" means any non-source
+form of a work.
+
+  A "Standard Interface" means an interface that either is an official
+standard defined by a recognized standards body, or, in the case of
+interfaces specified for a particular programming language, one that
+is widely used among developers working in that language.
+
+  The "System Libraries" of an executable work include anything, other
+than the work as a whole, that (a) is included in the normal form of
+packaging a Major Component, but which is not part of that Major
+Component, and (b) serves only to enable use of the work with that
+Major Component, or to implement a Standard Interface for which an
+implementation is available to the public in source code form.  A
+"Major Component", in this context, means a major essential component
+(kernel, window system, and so on) of the specific operating system
+(if any) on which the executable work runs, or a compiler used to
+produce the work, or an object code interpreter used to run it.
+
+  The "Corresponding Source" for a work in object code form means all
+the source code needed to generate, install, and (for an executable
+work) run the object code and to modify the work, including scripts to
+control those activities.  However, it does not include the work's
+System Libraries, or general-purpose tools or generally available free
+programs which are used unmodified in performing those activities but
+which are not part of the work.  For example, Corresponding Source
+includes interface definition files associated with source files for
+the work, and the source code for shared libraries and dynamically
+linked subprograms that the work is specifically designed to require,
+such as by intimate data communication or control flow between those
+subprograms and other parts of the work.
+
+  The Corresponding Source need not include anything that users
+can regenerate automatically from other parts of the Corresponding
+Source.
+
+  The Corresponding Source for a work in source code form is that
+same work.
+
+  2. Basic Permissions.
+
+  All rights granted under this License are granted for the term of
+copyright on the Program, and are irrevocable provided the stated
+conditions are met.  This License explicitly affirms your unlimited
+permission to run the unmodified Program.  The output from running a
+covered work is covered by this License only if the output, given its
+content, constitutes a covered work.  This License acknowledges your
+rights of fair use or other equivalent, as provided by copyright law.
+
+  You may make, run and propagate covered works that you do not
+convey, without conditions so long as your license otherwise remains
+in force.  You may convey covered works to others for the sole purpose
+of having them make modifications exclusively for you, or provide you
+with facilities for running those works, provided that you comply with
+the terms of this License in conveying all material for which you do
+not control copyright.  Those thus making or running the covered works
+for you must do so exclusively on your behalf, under your direction
+and control, on terms that prohibit them from making any copies of
+your copyrighted material outside their relationship with you.
+
+  Conveying under any other circumstances is permitted solely under
+the conditions stated below.  Sublicensing is not allowed; section 10
+makes it unnecessary.
+
+  3. Protecting Users' Legal Rights From Anti-Circumvention Law.
+
+  No covered work shall be deemed part of an effective technological
+measure under any applicable law fulfilling obligations under article
+11 of the WIPO copyright treaty adopted on 20 December 1996, or
+similar laws prohibiting or restricting circumvention of such
+measures.
+
+  When you convey a covered work, you waive any legal power to forbid
+circumvention of technological measures to the extent such circumvention
+is effected by exercising rights under this License with respect to
+the covered work, and you disclaim any intention to limit operation or
+modification of the work as a means of enforcing, against the work's
+users, your or third parties' legal rights to forbid circumvention of
+technological measures.
+
+  4. Conveying Verbatim Copies.
+
+  You may convey verbatim copies of the Program's source code as you
+receive it, in any medium, provided that you conspicuously and
+appropriately publish on each copy an appropriate copyright notice;
+keep intact all notices stating that this License and any
+non-permissive terms added in accord with section 7 apply to the code;
+keep intact all notices of the absence of any warranty; and give all
+recipients a copy of this License along with the Program.
+
+  You may charge any price or no price for each copy that you convey,
+and you may offer support or warranty protection for a fee.
+
+  5. Conveying Modified Source Versions.
+
+  You may convey a work based on the Program, or the modifications to
+produce it from the Program, in the form of source code under the
+terms of section 4, provided that you also meet all of these conditions:
+
+    a) The work must carry prominent notices stating that you modified
+    it, and giving a relevant date.
+
+    b) The work must carry prominent notices stating that it is
+    released under this License and any conditions added under section
+    7.  This requirement modifies the requirement in section 4 to
+    "keep intact all notices".
+
+    c) You must license the entire work, as a whole, under this
+    License to anyone who comes into possession of a copy.  This
+    License will therefore apply, along with any applicable section 7
+    additional terms, to the whole of the work, and all its parts,
+    regardless of how they are packaged.  This License gives no
+    permission to license the work in any other way, but it does not
+    invalidate such permission if you have separately received it.
+
+    d) If the work has interactive user interfaces, each must display
+    Appropriate Legal Notices; however, if the Program has interactive
+    interfaces that do not display Appropriate Legal Notices, your
+    work need not make them do so.
+
+  A compilation of a covered work with other separate and independent
+works, which are not by their nature extensions of the covered work,
+and which are not combined with it such as to form a larger program,
+in or on a volume of a storage or distribution medium, is called an
+"aggregate" if the compilation and its resulting copyright are not
+used to limit the access or legal rights of the compilation's users
+beyond what the individual works permit.  Inclusion of a covered work
+in an aggregate does not cause this License to apply to the other
+parts of the aggregate.
+
+  6. Conveying Non-Source Forms.
+
+  You may convey a covered work in object code form under the terms
+of sections 4 and 5, provided that you also convey the
+machine-readable Corresponding Source under the terms of this License,
+in one of these ways:
+
+    a) Convey the object code in, or embodied in, a physical product
+    (including a physical distribution medium), accompanied by the
+    Corresponding Source fixed on a durable physical medium
+    customarily used for software interchange.
+
+    b) Convey the object code in, or embodied in, a physical product
+    (including a physical distribution medium), accompanied by a
+    written offer, valid for at least three years and valid for as
+    long as you offer spare parts or customer support for that product
+    model, to give anyone who possesses the object code either (1) a
+    copy of the Corresponding Source for all the software in the
+    product that is covered by this License, on a durable physical
+    medium customarily used for software interchange, for a price no
+    more than your reasonable cost of physically performing this
+    conveying of source, or (2) access to copy the
+    Corresponding Source from a network server at no charge.
+
+    c) Convey individual copies of the object code with a copy of the
+    written offer to provide the Corresponding Source.  This
+    alternative is allowed only occasionally and noncommercially, and
+    only if you received the object code with such an offer, in accord
+    with subsection 6b.
+
+    d) Convey the object code by offering access from a designated
+    place (gratis or for a charge), and offer equivalent access to the
+    Corresponding Source in the same way through the same place at no
+    further charge.  You need not require recipients to copy the
+    Corresponding Source along with the object code.  If the place to
+    copy the object code is a network server, the Corresponding Source
+    may be on a different server (operated by you or a third party)
+    that supports equivalent copying facilities, provided you maintain
+    clear directions next to the object code saying where to find the
+    Corresponding Source.  Regardless of what server hosts the
+    Corresponding Source, you remain obligated to ensure that it is
+    available for as long as needed to satisfy these requirements.
+
+    e) Convey the object code using peer-to-peer transmission, provided
+    you inform other peers where the object code and Corresponding
+    Source of the work are being offered to the general public at no
+    charge under subsection 6d.
+
+  A separable portion of the object code, whose source code is excluded
+from the Corresponding Source as a System Library, need not be
+included in conveying the object code work.
+
+  A "User Product" is either (1) a "consumer product", which means any
+tangible personal property which is normally used for personal, family,
+or household purposes, or (2) anything designed or sold for incorporation
+into a dwelling.  In determining whether a product is a consumer product,
+doubtful cases shall be resolved in favor of coverage.  For a particular
+product received by a particular user, "normally used" refers to a
+typical or common use of that class of product, regardless of the status
+of the particular user or of the way in which the particular user
+actually uses, or expects or is expected to use, the product.  A product
+is a consumer product regardless of whether the product has substantial
+commercial, industrial or non-consumer uses, unless such uses represent
+the only significant mode of use of the product.
+
+  "Installation Information" for a User Product means any methods,
+procedures, authorization keys, or other information required to install
+and execute modified versions of a covered work in that User Product from
+a modified version of its Corresponding Source.  The information must
+suffice to ensure that the continued functioning of the modified object
+code is in no case prevented or interfered with solely because
+modification has been made.
+
+  If you convey an object code work under this section in, or with, or
+specifically for use in, a User Product, and the conveying occurs as
+part of a transaction in which the right of possession and use of the
+User Product is transferred to the recipient in perpetuity or for a
+fixed term (regardless of how the transaction is characterized), the
+Corresponding Source conveyed under this section must be accompanied
+by the Installation Information.  But this requirement does not apply
+if neither you nor any third party retains the ability to install
+modified object code on the User Product (for example, the work has
+been installed in ROM).
+
+  The requirement to provide Installation Information does not include a
+requirement to continue to provide support service, warranty, or updates
+for a work that has been modified or installed by the recipient, or for
+the User Product in which it has been modified or installed.  Access to a
+network may be denied when the modification itself materially and
+adversely affects the operation of the network or violates the rules and
+protocols for communication across the network.
+
+  Corresponding Source conveyed, and Installation Information provided,
+in accord with this section must be in a format that is publicly
+documented (and with an implementation available to the public in
+source code form), and must require no special password or key for
+unpacking, reading or copying.
+
+  7. Additional Terms.
+
+  "Additional permissions" are terms that supplement the terms of this
+License by making exceptions from one or more of its conditions.
+Additional permissions that are applicable to the entire Program shall
+be treated as though they were included in this License, to the extent
+that they are valid under applicable law.  If additional permissions
+apply only to part of the Program, that part may be used separately
+under those permissions, but the entire Program remains governed by
+this License without regard to the additional permissions.
+
+  When you convey a copy of a covered work, you may at your option
+remove any additional permissions from that copy, or from any part of
+it.  (Additional permissions may be written to require their own
+removal in certain cases when you modify the work.)  You may place
+additional permissions on material, added by you to a covered work,
+for which you have or can give appropriate copyright permission.
+
+  Notwithstanding any other provision of this License, for material you
+add to a covered work, you may (if authorized by the copyright holders of
+that material) supplement the terms of this License with terms:
+
+    a) Disclaiming warranty or limiting liability differently from the
+    terms of sections 15 and 16 of this License; or
+
+    b) Requiring preservation of specified reasonable legal notices or
+    author attributions in that material or in the Appropriate Legal
+    Notices displayed by works containing it; or
+
+    c) Prohibiting misrepresentation of the origin of that material, or
+    requiring that modified versions of such material be marked in
+    reasonable ways as different from the original version; or
+
+    d) Limiting the use for publicity purposes of names of licensors or
+    authors of the material; or
+
+    e) Declining to grant rights under trademark law for use of some
+    trade names, trademarks, or service marks; or
+
+    f) Requiring indemnification of licensors and authors of that
+    material by anyone who conveys the material (or modified versions of
+    it) with contractual assumptions of liability to the recipient, for
+    any liability that these contractual assumptions directly impose on
+    those licensors and authors.
+
+  All other non-permissive additional terms are considered "further
+restrictions" within the meaning of section 10.  If the Program as you
+received it, or any part of it, contains a notice stating that it is
+governed by this License along with a term that is a further
+restriction, you may remove that term.  If a license document contains
+a further restriction but permits relicensing or conveying under this
+License, you may add to a covered work material governed by the terms
+of that license document, provided that the further restriction does
+not survive such relicensing or conveying.
+
+  If you add terms to a covered work in accord with this section, you
+must place, in the relevant source files, a statement of the
+additional terms that apply to those files, or a notice indicating
+where to find the applicable terms.
+
+  Additional terms, permissive or non-permissive, may be stated in the
+form of a separately written license, or stated as exceptions;
+the above requirements apply either way.
+
+  8. Termination.
+
+  You may not propagate or modify a covered work except as expressly
+provided under this License.  Any attempt otherwise to propagate or
+modify it is void, and will automatically terminate your rights under
+this License (including any patent licenses granted under the third
+paragraph of section 11).
+
+  However, if you cease all violation of this License, then your
+license from a particular copyright holder is reinstated (a)
+provisionally, unless and until the copyright holder explicitly and
+finally terminates your license, and (b) permanently, if the copyright
+holder fails to notify you of the violation by some reasonable means
+prior to 60 days after the cessation.
+
+  Moreover, your license from a particular copyright holder is
+reinstated permanently if the copyright holder notifies you of the
+violation by some reasonable means, this is the first time you have
+received notice of violation of this License (for any work) from that
+copyright holder, and you cure the violation prior to 30 days after
+your receipt of the notice.
+
+  Termination of your rights under this section does not terminate the
+licenses of parties who have received copies or rights from you under
+this License.  If your rights have been terminated and not permanently
+reinstated, you do not qualify to receive new licenses for the same
+material under section 10.
+
+  9. Acceptance Not Required for Having Copies.
+
+  You are not required to accept this License in order to receive or
+run a copy of the Program.  Ancillary propagation of a covered work
+occurring solely as a consequence of using peer-to-peer transmission
+to receive a copy likewise does not require acceptance.  However,
+nothing other than this License grants you permission to propagate or
+modify any covered work.  These actions infringe copyright if you do
+not accept this License.  Therefore, by modifying or propagating a
+covered work, you indicate your acceptance of this License to do so.
+
+  10. Automatic Licensing of Downstream Recipients.
+
+  Each time you convey a covered work, the recipient automatically
+receives a license from the original licensors, to run, modify and
+propagate that work, subject to this License.  You are not responsible
+for enforcing compliance by third parties with this License.
+
+  An "entity transaction" is a transaction transferring control of an
+organization, or substantially all assets of one, or subdividing an
+organization, or merging organizations.  If propagation of a covered
+work results from an entity transaction, each party to that
+transaction who receives a copy of the work also receives whatever
+licenses to the work the party's predecessor in interest had or could
+give under the previous paragraph, plus a right to possession of the
+Corresponding Source of the work from the predecessor in interest, if
+the predecessor has it or can get it with reasonable efforts.
+
+  You may not impose any further restrictions on the exercise of the
+rights granted or affirmed under this License.  For example, you may
+not impose a license fee, royalty, or other charge for exercise of
+rights granted under this License, and you may not initiate litigation
+(including a cross-claim or counterclaim in a lawsuit) alleging that
+any patent claim is infringed by making, using, selling, offering for
+sale, or importing the Program or any portion of it.
+
+  11. Patents.
+
+  A "contributor" is a copyright holder who authorizes use under this
+License of the Program or a work on which the Program is based.  The
+work thus licensed is called the contributor's "contributor version".
+
+  A contributor's "essential patent claims" are all patent claims
+owned or controlled by the contributor, whether already acquired or
+hereafter acquired, that would be infringed by some manner, permitted
+by this License, of making, using, or selling its contributor version,
+but do not include claims that would be infringed only as a
+consequence of further modification of the contributor version.  For
+purposes of this definition, "control" includes the right to grant
+patent sublicenses in a manner consistent with the requirements of
+this License.
+
+  Each contributor grants you a non-exclusive, worldwide, royalty-free
+patent license under the contributor's essential patent claims, to
+make, use, sell, offer for sale, import and otherwise run, modify and
+propagate the contents of its contributor version.
+
+  In the following three paragraphs, a "patent license" is any express
+agreement or commitment, however denominated, not to enforce a patent
+(such as an express permission to practice a patent or covenant not to
+sue for patent infringement).  To "grant" such a patent license to a
+party means to make such an agreement or commitment not to enforce a
+patent against the party.
+
+  If you convey a covered work, knowingly relying on a patent license,
+and the Corresponding Source of the work is not available for anyone
+to copy, free of charge and under the terms of this License, through a
+publicly available network server or other readily accessible means,
+then you must either (1) cause the Corresponding Source to be so
+available, or (2) arrange to deprive yourself of the benefit of the
+patent license for this particular work, or (3) arrange, in a manner
+consistent with the requirements of this License, to extend the patent
+license to downstream recipients.  "Knowingly relying" means you have
+actual knowledge that, but for the patent license, your conveying the
+covered work in a country, or your recipient's use of the covered work
+in a country, would infringe one or more identifiable patents in that
+country that you have reason to believe are valid.
+
+  If, pursuant to or in connection with a single transaction or
+arrangement, you convey, or propagate by procuring conveyance of, a
+covered work, and grant a patent license to some of the parties
+receiving the covered work authorizing them to use, propagate, modify
+or convey a specific copy of the covered work, then the patent license
+you grant is automatically extended to all recipients of the covered
+work and works based on it.
+
+  A patent license is "discriminatory" if it does not include within
+the scope of its coverage, prohibits the exercise of, or is
+conditioned on the non-exercise of one or more of the rights that are
+specifically granted under this License.  You may not convey a covered
+work if you are a party to an arrangement with a third party that is
+in the business of distributing software, under which you make payment
+to the third party based on the extent of your activity of conveying
+the work, and under which the third party grants, to any of the
+parties who would receive the covered work from you, a discriminatory
+patent license (a) in connection with copies of the covered work
+conveyed by you (or copies made from those copies), or (b) primarily
+for and in connection with specific products or compilations that
+contain the covered work, unless you entered into that arrangement,
+or that patent license was granted, prior to 28 March 2007.
+
+  Nothing in this License shall be construed as excluding or limiting
+any implied license or other defenses to infringement that may
+otherwise be available to you under applicable patent law.
+
+  12. No Surrender of Others' Freedom.
+
+  If conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License.  If you cannot convey a
+covered work so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you may
+not convey it at all.  For example, if you agree to terms that obligate you
+to collect a royalty for further conveying from those to whom you convey
+the Program, the only way you could satisfy both those terms and this
+License would be to refrain entirely from conveying the Program.
+
+  13. Use with the GNU Affero General Public License.
+
+  Notwithstanding any other provision of this License, you have
+permission to link or combine any covered work with a work licensed
+under version 3 of the GNU Affero General Public License into a single
+combined work, and to convey the resulting work.  The terms of this
+License will continue to apply to the part which is the covered work,
+but the special requirements of the GNU Affero General Public License,
+section 13, concerning interaction through a network will apply to the
+combination as such.
+
+  14. Revised Versions of this License.
+
+  The Free Software Foundation may publish revised and/or new versions of
+the GNU General Public License from time to time.  Such new versions will
+be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.
+
+  Each version is given a distinguishing version number.  If the
+Program specifies that a certain numbered version of the GNU General
+Public License "or any later version" applies to it, you have the
+option of following the terms and conditions either of that numbered
+version or of any later version published by the Free Software
+Foundation.  If the Program does not specify a version number of the
+GNU General Public License, you may choose any version ever published
+by the Free Software Foundation.
+
+  If the Program specifies that a proxy can decide which future
+versions of the GNU General Public License can be used, that proxy's
+public statement of acceptance of a version permanently authorizes you
+to choose that version for the Program.
+
+  Later license versions may give you additional or different
+permissions.  However, no additional obligations are imposed on any
+author or copyright holder as a result of your choosing to follow a
+later version.
+
+  15. Disclaimer of Warranty.
+
+  THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
+APPLICABLE LAW.  EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
+HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY
+OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
+THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
+PURPOSE.  THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM
+IS WITH YOU.  SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
+ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
+
+  16. Limitation of Liability.
+
+  IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
+THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
+GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE
+USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF
+DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
+PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),
+EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF
+SUCH DAMAGES.
+
+  17. Interpretation of Sections 15 and 16.
+
+  If the disclaimer of warranty and limitation of liability provided
+above cannot be given local legal effect according to their terms,
+reviewing courts shall apply local law that most closely approximates
+an absolute waiver of all civil liability in connection with the
+Program, unless a warranty or assumption of liability accompanies a

+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+
+  This version of the GNU Lesser General Public License incorporates
+the terms and conditions of version 3 of the GNU General Public
+License, supplemented by the additional permissions listed below.
+
+  0. Additional Definitions.
+
+  As used herein, "this License" refers to version 3 of the GNU Lesser
+General Public License, and the "GNU GPL" refers to version 3 of the GNU
+General Public License.
+
+  "The Library" refers to a covered work governed by this License,
+other than an Application or a Combined Work as defined below.
+
+  An "Application" is any work that makes use of an interface provided
+by the Library, but which is not otherwise based on the Library.
+Defining a subclass of a class defined by the Library is deemed a mode
+of using an interface provided by the Library.
+
+  A "Combined Work" is a work produced by combining or linking an
+Application with the Library.  The particular version of the Library
+with which the Combined Work was made is also called the "Linked
+Version".
+
+  The "Minimal Corresponding Source" for a Combined Work means the
+Corresponding Source for the Combined Work, excluding any source code
+for portions of the Combined Work that, considered in isolation, are
+based on the Application, and not on the Linked Version.
+
+  The "Corresponding Application Code" for a Combined Work means the
+object code and/or source code for the Application, including any data
+and utility programs needed for reproducing the Combined Work from the
+Application, but excluding the System Libraries of the Combined Work.
+
+  1. Exception to Section 3 of the GNU GPL.
+
+  You may convey a covered work under sections 3 and 4 of this License
+without being bound by section 3 of the GNU GPL.
+
+  2. Conveying Modified Versions.
+
+  If you modify a copy of the Library, and, in your modifications, a
+facility refers to a function or data to be supplied by an Application
+that uses the facility (other than as an argument passed when the
+facility is invoked), then you may convey a copy of the modified
+version:
+
+   a) under this License, provided that you make a good faith effort to
+   ensure that, in the event an Application does not supply the
+   function or data, the facility still operates, and performs
+   whatever part of its purpose remains meaningful, or
+
+   b) under the GNU GPL, with none of the additional permissions of
+   this License applicable to that copy.
+
+  3. Object Code Incorporating Material from Library Header Files.
+
+  The object code form of an Application may incorporate material from
+a header file that is part of the Library.  You may convey such object
+code under terms of your choice, provided that, if the incorporated
+material is not limited to numerical parameters, data structure
+layouts and accessors, or small macros, inline functions and templates
+(ten or fewer lines in length), you do both of the following:
+
+   a) Give prominent notice with each copy of the object code that the
+   Library is used in it and that the Library and its use are
+   covered by this License.
+
+   b) Accompany the object code with a copy of the GNU GPL and this license
+   document.
+
+  4. Combined Works.
+
+  You may convey a Combined Work under terms of your choice that,
+taken together, effectively do not restrict modification of the
+portions of the Library contained in the Combined Work and reverse
+engineering for debugging such modifications, if you also do each of
+the following:
+
+   a) Give prominent notice with each copy of the Combined Work that
+   the Library is used in it and that the Library and its use are
+   covered by this License.
+
+   b) Accompany the Combined Work with a copy of the GNU GPL and this license
+   document.
+
+   c) For a Combined Work that displays copyright notices during
+   execution, include the copyright notice for the Library among
+   these notices, as well as a reference directing the user to the
+   copies of the GNU GPL and this license document.
+
+   d) Do one of the following:
+
+       0) Convey the Minimal Corresponding Source under the terms of this
+       License, and the Corresponding Application Code in a form
+       suitable for, and under terms that permit, the user to
+       recombine or relink the Application with a modified version of
+       the Linked Version to produce a modified Combined Work, in the
+       manner specified by section 6 of the GNU GPL for conveying
+       Corresponding Source.
+
+       1) Use a suitable shared library mechanism for linking with the
+       Library.  A suitable mechanism is one that (a) uses at run time
+       a copy of the Library already present on the user's computer
+       system, and (b) will operate properly with a modified version
+       of the Library that is interface-compatible with the Linked
+       Version.
+
+   e) Provide Installation Information, but only if you would otherwise
+   be required to provide such information under section 6 of the
+   GNU GPL, and only to the extent that such information is
+   necessary to install and execute a modified version of the
+   Combined Work produced by recombining or relinking the
+   Application with a modified version of the Linked Version. (If
+   you use option 4d0, the Installation Information must accompany
+   the Minimal Corresponding Source and Corresponding Application
+   Code. If you use option 4d1, you must provide the Installation
+   Information in the manner specified by section 6 of the GNU GPL
+   for conveying Corresponding Source.)
+
+  5. Combined Libraries.
+
+  You may place library facilities that are a work based on the
+Library side by side in a single library together with other library
+facilities that are not Applications and are not covered by this
+License, and convey such a combined library under terms of your
+choice, if you do both of the following:
+
+   a) Accompany the combined library with a copy of the same work based
+   on the Library, uncombined with any other library facilities,
+   conveyed under the terms of this License.
+
+   b) Give prominent notice with the combined library that part of it
+   is a work based on the Library, and explaining where to find the
+   accompanying uncombined form of the same work.
+
+  6. Revised Versions of the GNU Lesser General Public License.
+
+  The Free Software Foundation may publish revised and/or new versions
+of the GNU Lesser General Public License from time to time. Such new
+versions will be similar in spirit to the present version, but may
+differ in detail to address new problems or concerns.
+
+  Each version is given a distinguishing version number. If the
+Library as you received it specifies that a certain numbered version
+of the GNU Lesser General Public License "or any later version"
+applies to it, you have the option of following the terms and
+conditions either of that published version or of any later version
+published by the Free Software Foundation. If the Library as you
+received it does not specify a version number of the GNU Lesser
+General Public License, you may choose any version of the GNU Lesser
+General Public License ever published by the Free Software Foundation.
+
+  If the Library as you received it specifies that a proxy can decide
+whether future versions of the GNU Lesser General Public License shall
+apply, that proxy's public statement of acceptance of any version is
+permanent authorization for you to choose that version for the
+Library.

+# ifcclash
+
+`ifcclash` is both a CLI utility and library that lets you perform clash
+detections on and between IFC files.
+
+## Installation
+
+`ifcclash` depends on
+[`hppfcl`](https://github.com/humanoid-path-planner/hpp-fcl) and optionally
+[`bcf`](https://github.com/IfcOpenShell/IfcOpenShell/tree/v0.6.0/src/bcf). Once
+you have the dependencies, the `ifcclash` directory may be added to your Python
+site packages like any other Python module. You can run it as a CLI like:
+
+```
+$ python -m ifcclash
+```
+
+If you want something more Unix-like ...
+
+```
+$ alias ifcclash='python -m ifcclash'
+```
+
+Alternatively, you can package it as a distributable.
+
+```
+$ python make.py
+$ ./dist/ifcclash
+```
+
+## Usage
+
+Instructions on what clashes to perform are structured in terms of clash sets.
+Each clash set contains instructions of collisions that we want to perform, and
+can be named so it is easy to distinguish. A typical name would be "Structure
+and Pipes", to describe that we are are detecting collisions between structural
+elements and pipes.
+
+Each clash set may include two groups of objects, named `A` and `B`. This tells
+IfcClash to attempt to find collisions between any object in group `A` with any
+object in group `B`. Group `A` is mandatory, but group `B` is optional. If group
+`B` is not provided, IfcClash will detect all clashes within objects of group
+`A`.
+
+Within group `A` or `B`, you may be define one or more data sources of objects.
+A data source must include a path to the IFC file which the objects come from.
+You may also optionally provide a filter to only include or exclude certain
+objects. If no filter is provided, then all objects will be used to detect
+collisions.
+
+Here's a sample JSON description of a single clash set, with both groups
+defined with data sources.
+
+```json
+[
+    {
+        "name": "Clash Set A",
+        "a": [
+            {
+                "file": "/path/to/one.ifc"
+            }
+        ],
+        "b": [
+            {
+                "file": "/path/to/two.ifc",
+                "selector": ".IfcWall",
+                "mode": "i"
+            }
+        ]
+    }
+]
+```
+
+Once your have your JSON description of your clashes, usage is like any other
+CLI app.
+
+```
+$ ifcclash -h
+
+usage: __main__.py [-h] [-o OUTPUT] input
+
+Clashes geometry between two IFC files
+
+positional arguments:
+  input                 A JSON dataset describing a series of clashsets
+
+optional arguments:
+  -h, --help            show this help message and exit
+  -o OUTPUT, --output OUTPUT
+                        The JSON diff file to output. Defaults to output.json
+```
+
+In it simplest form, just present your JSON file.
+
+```
+$ ifcclash clash_sets.json
+$ cat output.json
+```
+
+You can also use it as a library.
+
+```python
+import sys
+import json
+import logging
+import ifcclash
+
+
+settings = ClashSettings()
+settings.output = "output.json"
+settings.logger = logging.getLogger("Clash")
+settings.logger.setLevel(logging.DEBUG)
+handler = logging.StreamHandler(sys.stdout)
+handler.setLevel(logging.DEBUG)
+settings.logger.addHandler(handler)
+ifc_clasher = Clasher(settings)
+with open(args.input, "r") as clash_sets_file:
+    ifc_clasher.clash_sets = json.loads(clash_sets_file.read())
+ifc_clasher.clash()
+ifc_clasher.export()
+```

+                    GNU GENERAL PUBLIC LICENSE
+                       Version 3, 29 June 2007
+
+ Copyright (C) 2007 Free Software Foundation, Inc. <https://fsf.org/>
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+                            Preamble
+
+  The GNU General Public License is a free, copyleft license for
+software and other kinds of works.
+
+  The licenses for most software and other practical works are designed
+to take away your freedom to share and change the works.  By contrast,
+the GNU General Public License is intended to guarantee your freedom to
+share and change all versions of a program--to make sure it remains free
+software for all its users.  We, the Free Software Foundation, use the
+GNU General Public License for most of our software; it applies also to
+any other work released this way by its authors.  You can apply it to
+your programs, too.
+
+  When we speak of free software, we are referring to freedom, not
+price.  Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+them if you wish), that you receive source code or can get it if you
+want it, that you can change the software or use pieces of it in new
+free programs, and that you know you can do these things.
+
+  To protect your rights, we need to prevent others from denying you
+these rights or asking you to surrender the rights.  Therefore, you have
+certain responsibilities if you distribute copies of the software, or if
+you modify it: responsibilities to respect the freedom of others.
+
+  For example, if you distribute copies of such a program, whether
+gratis or for a fee, you must pass on to the recipients the same
+freedoms that you received.  You must make sure that they, too, receive
+or can get the source code.  And you must show them these terms so they
+know their rights.
+
+  Developers that use the GNU GPL protect your rights with two steps:
+(1) assert copyright on the software, and (2) offer you this License
+giving you legal permission to copy, distribute and/or modify it.
+
+  For the developers' and authors' protection, the GPL clearly explains
+that there is no warranty for this free software.  For both users' and
+authors' sake, the GPL requires that modified versions be marked as
+changed, so that their problems will not be attributed erroneously to
+authors of previous versions.
+
+  Some devices are designed to deny users access to install or run
+modified versions of the software inside them, although the manufacturer
+can do so.  This is fundamentally incompatible with the aim of
+protecting users' freedom to change the software.  The systematic
+pattern of such abuse occurs in the area of products for individuals to
+use, which is precisely where it is most unacceptable.  Therefore, we
+have designed this version of the GPL to prohibit the practice for those
+products.  If such problems arise substantially in other domains, we
+stand ready to extend this provision to those domains in future versions
+of the GPL, as needed to protect the freedom of users.
+
+  Finally, every program is threatened constantly by software patents.
+States should not allow patents to restrict development and use of
+software on general-purpose computers, but in those that do, we wish to
+avoid the special danger that patents applied to a free program could
+make it effectively proprietary.  To prevent this, the GPL assures that
+patents cannot be used to render the program non-free.
+
+  The precise terms and conditions for copying, distribution and
+modification follow.
+
+                       TERMS AND CONDITIONS
+
+  0. Definitions.
+
+  "This License" refers to version 3 of the GNU General Public License.
+
+  "Copyright" also means copyright-like laws that apply to other kinds of
+works, such as semiconductor masks.
+
+  "The Program" refers to any copyrightable work licensed under this
+License.  Each licensee is addressed as "you".  "Licensees" and
+"recipients" may be individuals or organizations.
+
+  To "modify" a work means to copy from or adapt all or part of the work
+in a fashion requiring copyright permission, other than the making of an
+exact copy.  The resulting work is called a "modified version" of the
+earlier work or a work "based on" the earlier work.
+
+  A "covered work" means either the unmodified Program or a work based
+on the Program.
+
+  To "propagate" a work means to do anything with it that, without
+permission, would make you directly or secondarily liable for
+infringement under applicable copyright law, except executing it on a
+computer or modifying a private copy.  Propagation includes copying,
+distribution (with or without modification), making available to the
+public, and in some countries other activities as well.
+
+  To "convey" a work means any kind of propagation that enables other
+parties to make or receive copies.  Mere interaction with a user through
+a computer network, with no transfer of a copy, is not conveying.
+
+  An interactive user interface displays "Appropriate Legal Notices"
+to the extent that it includes a convenient and prominently visible
+feature that (1) displays an appropriate copyright notice, and (2)
+tells the user that there is no warranty for the work (except to the
+extent that warranties are provided), that licensees may convey the
+work under this License, and how to view a copy of this License.  If
+the interface presents a list of user commands or options, such as a
+menu, a prominent item in the list meets this criterion.
+
+  1. Source Code.
+
+  The "source code" for a work means the preferred form of the work
+for making modifications to it.  "Object code" means any non-source
+form of a work.
+
+  A "Standard Interface" means an interface that either is an official
+standard defined by a recognized standards body, or, in the case of
+interfaces specified for a particular programming language, one that
+is widely used among developers working in that language.
+
+  The "System Libraries" of an executable work include anything, other
+than the work as a whole, that (a) is included in the normal form of
+packaging a Major Component, but which is not part of that Major
+Component, and (b) serves only to enable use of the work with that
+Major Component, or to implement a Standard Interface for which an
+implementation is available to the public in source code form.  A
+"Major Component", in this context, means a major essential component
+(kernel, window system, and so on) of the specific operating system
+(if any) on which the executable work runs, or a compiler used to
+produce the work, or an object code interpreter used to run it.
+
+  The "Corresponding Source" for a work in object code form means all
+the source code needed to generate, install, and (for an executable
+work) run the object code and to modify the work, including scripts to
+control those activities.  However, it does not include the work's
+System Libraries, or general-purpose tools or generally available free
+programs which are used unmodified in performing those activities but
+which are not part of the work.  For example, Corresponding Source
+includes interface definition files associated with source files for
+the work, and the source code for shared libraries and dynamically
+linked subprograms that the work is specifically designed to require,
+such as by intimate data communication or control flow between those
+subprograms and other parts of the work.
+
+  The Corresponding Source need not include anything that users
+can regenerate automatically from other parts of the Corresponding
+Source.
+
+  The Corresponding Source for a work in source code form is that
+same work.
+
+  2. Basic Permissions.
+
+  All rights granted under this License are granted for the term of
+copyright on the Program, and are irrevocable provided the stated
+conditions are met.  This License explicitly affirms your unlimited
+permission to run the unmodified Program.  The output from running a
+covered work is covered by this License only if the output, given its
+content, constitutes a covered work.  This License acknowledges your
+rights of fair use or other equivalent, as provided by copyright law.
+
+  You may make, run and propagate covered works that you do not
+convey, without conditions so long as your license otherwise remains
+in force.  You may convey covered works to others for the sole purpose
+of having them make modifications exclusively for you, or provide you
+with facilities for running those works, provided that you comply with
+the terms of this License in conveying all material for which you do
+not control copyright.  Those thus making or running the covered works
+for you must do so exclusively on your behalf, under your direction
+and control, on terms that prohibit them from making any copies of
+your copyrighted material outside their relationship with you.
+
+  Conveying under any other circumstances is permitted solely under
+the conditions stated below.  Sublicensing is not allowed; section 10
+makes it unnecessary.
+
+  3. Protecting Users' Legal Rights From Anti-Circumvention Law.
+
+  No covered work shall be deemed part of an effective technological
+measure under any applicable law fulfilling obligations under article
+11 of the WIPO copyright treaty adopted on 20 December 1996, or
+similar laws prohibiting or restricting circumvention of such
+measures.
+
+  When you convey a covered work, you waive any legal power to forbid
+circumvention of technological measures to the extent such circumvention
+is effected by exercising rights under this License with respect to
+the covered work, and you disclaim any intention to limit operation or
+modification of the work as a means of enforcing, against the work's
+users, your or third parties' legal rights to forbid circumvention of
+technological measures.
+
+  4. Conveying Verbatim Copies.
+
+  You may convey verbatim copies of the Program's source code as you
+receive it, in any medium, provided that you conspicuously and
+appropriately publish on each copy an appropriate copyright notice;
+keep intact all notices stating that this License and any
+non-permissive terms added in accord with section 7 apply to the code;
+keep intact all notices of the absence of any warranty; and give all
+recipients a copy of this License along with the Program.
+
+  You may charge any price or no price for each copy that you convey,
+and you may offer support or warranty protection for a fee.
+
+  5. Conveying Modified Source Versions.
+
+  You may convey a work based on the Program, or the modifications to
+produce it from the Program, in the form of source code under the
+terms of section 4, provided that you also meet all of these conditions:
+
+    a) The work must carry prominent notices stating that you modified
+    it, and giving a relevant date.
+
+    b) The work must carry prominent notices stating that it is
+    released under this License and any conditions added under section
+    7.  This requirement modifies the requirement in section 4 to
+    "keep intact all notices".
+
+    c) You must license the entire work, as a whole, under this
+    License to anyone who comes into possession of a copy.  This
+    License will therefore apply, along with any applicable section 7
+    additional terms, to the whole of the work, and all its parts,
+    regardless of how they are packaged.  This License gives no
+    permission to license the work in any other way, but it does not
+    invalidate such permission if you have separately received it.
+
+    d) If the work has interactive user interfaces, each must display
+    Appropriate Legal Notices; however, if the Program has interactive
+    interfaces that do not display Appropriate Legal Notices, your
+    work need not make them do so.
+
+  A compilation of a covered work with other separate and independent
+works, which are not by their nature extensions of the covered work,
+and which are not combined with it such as to form a larger program,
+in or on a volume of a storage or distribution medium, is called an
+"aggregate" if the compilation and its resulting copyright are not
+used to limit the access or legal rights of the compilation's users
+beyond what the individual works permit.  Inclusion of a covered work
+in an aggregate does not cause this License to apply to the other
+parts of the aggregate.
+
+  6. Conveying Non-Source Forms.
+
+  You may convey a covered work in object code form under the terms
+of sections 4 and 5, provided that you also convey the
+machine-readable Corresponding Source under the terms of this License,
+in one of these ways:
+
+    a) Convey the object code in, or embodied in, a physical product
+    (including a physical distribution medium), accompanied by the
+    Corresponding Source fixed on a durable physical medium
+    customarily used for software interchange.
+
+    b) Convey the object code in, or embodied in, a physical product
+    (including a physical distribution medium), accompanied by a
+    written offer, valid for at least three years and valid for as
+    long as you offer spare parts or customer support for that product
+    model, to give anyone who possesses the object code either (1) a
+    copy of the Corresponding Source for all the software in the
+    product that is covered by this License, on a durable physical
+    medium customarily used for software interchange, for a price no
+    more than your reasonable cost of physically performing this
+    conveying of source, or (2) access to copy the
+    Corresponding Source from a network server at no charge.
+
+    c) Convey individual copies of the object code with a copy of the
+    written offer to provide the Corresponding Source.  This
+    alternative is allowed only occasionally and noncommercially, and
+    only if you received the object code with such an offer, in accord
+    with subsection 6b.
+
+    d) Convey the object code by offering access from a designated
+    place (gratis or for a charge), and offer equivalent access to the
+    Corresponding Source in the same way through the same place at no
+    further charge.  You need not require recipients to copy the
+    Corresponding Source along with the object code.  If the place to
+    copy the object code is a network server, the Corresponding Source
+    may be on a different server (operated by you or a third party)
+    that supports equivalent copying facilities, provided you maintain
+    clear directions next to the object code saying where to find the
+    Corresponding Source.  Regardless of what server hosts the
+    Corresponding Source, you remain obligated to ensure that it is
+    available for as long as needed to satisfy these requirements.
+
+    e) Convey the object code using peer-to-peer transmission, provided
+    you inform other peers where the object code and Corresponding
+    Source of the work are being offered to the general public at no
+    charge under subsection 6d.
+
+  A separable portion of the object code, whose source code is excluded
+from the Corresponding Source as a System Library, need not be
+included in conveying the object code work.
+
+  A "User Product" is either (1) a "consumer product", which means any
+tangible personal property which is normally used for personal, family,
+or household purposes, or (2) anything designed or sold for incorporation
+into a dwelling.  In determining whether a product is a consumer product,
+doubtful cases shall be resolved in favor of coverage.  For a particular
+product received by a particular user, "normally used" refers to a
+typical or common use of that class of product, regardless of the status
+of the particular user or of the way in which the particular user
+actually uses, or expects or is expected to use, the product.  A product
+is a consumer product regardless of whether the product has substantial
+commercial, industrial or non-consumer uses, unless such uses represent
+the only significant mode of use of the product.
+
+  "Installation Information" for a User Product means any methods,
+procedures, authorization keys, or other information required to install
+and execute modified versions of a covered work in that User Product from
+a modified version of its Corresponding Source.  The information must
+suffice to ensure that the continued functioning of the modified object
+code is in no case prevented or interfered with solely because
+modification has been made.
+
+  If you convey an object code work under this section in, or with, or
+specifically for use in, a User Product, and the conveying occurs as
+part of a transaction in which the right of possession and use of the
+User Product is transferred to the recipient in perpetuity or for a
+fixed term (regardless of how the transaction is characterized), the
+Corresponding Source conveyed under this section must be accompanied
+by the Installation Information.  But this requirement does not apply
+if neither you nor any third party retains the ability to install
+modified object code on the User Product (for example, the work has
+been installed in ROM).
+
+  The requirement to provide Installation Information does not include a
+requirement to continue to provide support service, warranty, or updates
+for a work that has been modified or installed by the recipient, or for
+the User Product in which it has been modified or installed.  Access to a
+network may be denied when the modification itself materially and
+adversely affects the operation of the network or violates the rules and
+protocols for communication across the network.
+
+  Corresponding Source conveyed, and Installation Information provided,
+in accord with this section must be in a format that is publicly
+documented (and with an implementation available to the public in
+source code form), and must require no special password or key for
+unpacking, reading or copying.
+
+  7. Additional Terms.
+
+  "Additional permissions" are terms that supplement the terms of this
+License by making exceptions from one or more of its conditions.
+Additional permissions that are applicable to the entire Program shall
+be treated as though they were included in this License, to the extent
+that they are valid under applicable law.  If additional permissions
+apply only to part of the Program, that part may be used separately
+under those permissions, but the entire Program remains governed by
+this License without regard to the additional permissions.
+
+  When you convey a copy of a covered work, you may at your option
+remove any additional permissions from that copy, or from any part of
+it.  (Additional permissions may be written to require their own
+removal in certain cases when you modify the work.)  You may place
+additional permissions on material, added by you to a covered work,
+for which you have or can give appropriate copyright permission.
+
+  Notwithstanding any other provision of this License, for material you
+add to a covered work, you may (if authorized by the copyright holders of
+that material) supplement the terms of this License with terms:
+
+    a) Disclaiming warranty or limiting liability differently from the
+    terms of sections 15 and 16 of this License; or
+
+    b) Requiring preservation of specified reasonable legal notices or
+    author attributions in that material or in the Appropriate Legal
+    Notices displayed by works containing it; or
+
+    c) Prohibiting misrepresentation of the origin of that material, or
+    requiring that modified versions of such material be marked in
+    reasonable ways as different from the original version; or
+
+    d) Limiting the use for publicity purposes of names of licensors or
+    authors of the material; or
+
+    e) Declining to grant rights under trademark law for use of some
+    trade names, trademarks, or service marks; or
+
+    f) Requiring indemnification of licensors and authors of that
+    material by anyone who conveys the material (or modified versions of
+    it) with contractual assumptions of liability to the recipient, for
+    any liability that these contractual assumptions directly impose on
+    those licensors and authors.
+
+  All other non-permissive additional terms are considered "further
+restrictions" within the meaning of section 10.  If the Program as you
+received it, or any part of it, contains a notice stating that it is
+governed by this License along with a term that is a further
+restriction, you may remove that term.  If a license document contains
+a further restriction but permits relicensing or conveying under this
+License, you may add to a covered work material governed by the terms
+of that license document, provided that the further restriction does
+not survive such relicensing or conveying.
+
+  If you add terms to a covered work in accord with this section, you
+must place, in the relevant source files, a statement of the
+additional terms that apply to those files, or a notice indicating
+where to find the applicable terms.
+
+  Additional terms, permissive or non-permissive, may be stated in the
+form of a separately written license, or stated as exceptions;
+the above requirements apply either way.
+
+  8. Termination.
+
+  You may not propagate or modify a covered work except as expressly
+provided under this License.  Any attempt otherwise to propagate or
+modify it is void, and will automatically terminate your rights under
+this License (including any patent licenses granted under the third
+paragraph of section 11).
+
+  However, if you cease all violation of this License, then your
+license from a particular copyright holder is reinstated (a)
+provisionally, unless and until the copyright holder explicitly and
+finally terminates your license, and (b) permanently, if the copyright
+holder fails to notify you of the violation by some reasonable means
+prior to 60 days after the cessation.
+
+  Moreover, your license from a particular copyright holder is
+reinstated permanently if the copyright holder notifies you of the
+violation by some reasonable means, this is the first time you have
+received notice of violation of this License (for any work) from that
+copyright holder, and you cure the violation prior to 30 days after
+your receipt of the notice.
+
+  Termination of your rights under this section does not terminate the
+licenses of parties who have received copies or rights from you under
+this License.  If your rights have been terminated and not permanently
+reinstated, you do not qualify to receive new licenses for the same
+material under section 10.
+
+  9. Acceptance Not Required for Having Copies.
+
+  You are not required to accept this License in order to receive or
+run a copy of the Program.  Ancillary propagation of a covered work
+occurring solely as a consequence of using peer-to-peer transmission
+to receive a copy likewise does not require acceptance.  However,
+nothing other than this License grants you permission to propagate or
+modify any covered work.  These actions infringe copyright if you do
+not accept this License.  Therefore, by modifying or propagating a
+covered work, you indicate your acceptance of this License to do so.
+
+  10. Automatic Licensing of Downstream Recipients.
+
+  Each time you convey a covered work, the recipient automatically
+receives a license from the original licensors, to run, modify and
+propagate that work, subject to this License.  You are not responsible
+for enforcing compliance by third parties with this License.
+
+  An "entity transaction" is a transaction transferring control of an
+organization, or substantially all assets of one, or subdividing an
+organization, or merging organizations.  If propagation of a covered
+work results from an entity transaction, each party to that
+transaction who receives a copy of the work also receives whatever
+licenses to the work the party's predecessor in interest had or could
+give under the previous paragraph, plus a right to possession of the
+Corresponding Source of the work from the predecessor in interest, if
+the predecessor has it or can get it with reasonable efforts.
+
+  You may not impose any further restrictions on the exercise of the
+rights granted or affirmed under this License.  For example, you may
+not impose a license fee, royalty, or other charge for exercise of
+rights granted under this License, and you may not initiate litigation
+(including a cross-claim or counterclaim in a lawsuit) alleging that
+any patent claim is infringed by making, using, selling, offering for
+sale, or importing the Program or any portion of it.
+
+  11. Patents.
+
+  A "contributor" is a copyright holder who authorizes use under this
+License of the Program or a work on which the Program is based.  The
+work thus licensed is called the contributor's "contributor version".
+
+  A contributor's "essential patent claims" are all patent claims
+owned or controlled by the contributor, whether already acquired or
+hereafter acquired, that would be infringed by some manner, permitted
+by this License, of making, using, or selling its contributor version,
+but do not include claims that would be infringed only as a
+consequence of further modification of the contributor version.  For
+purposes of this definition, "control" includes the right to grant
+patent sublicenses in a manner consistent with the requirements of
+this License.
+
+  Each contributor grants you a non-exclusive, worldwide, royalty-free
+patent license under the contributor's essential patent claims, to
+make, use, sell, offer for sale, import and otherwise run, modify and
+propagate the contents of its contributor version.
+
+  In the following three paragraphs, a "patent license" is any express
+agreement or commitment, however denominated, not to enforce a patent
+(such as an express permission to practice a patent or covenant not to
+sue for patent infringement).  To "grant" such a patent license to a
+party means to make such an agreement or commitment not to enforce a
+patent against the party.
+
+  If you convey a covered work, knowingly relying on a patent license,
+and the Corresponding Source of the work is not available for anyone
+to copy, free of charge and under the terms of this License, through a
+publicly available network server or other readily accessible means,
+then you must either (1) cause the Corresponding Source to be so
+available, or (2) arrange to deprive yourself of the benefit of the
+patent license for this particular work, or (3) arrange, in a manner
+consistent with the requirements of this License, to extend the patent
+license to downstream recipients.  "Knowingly relying" means you have
+actual knowledge that, but for the patent license, your conveying the
+covered work in a country, or your recipient's use of the covered work
+in a country, would infringe one or more identifiable patents in that
+country that you have reason to believe are valid.
+
+  If, pursuant to or in connection with a single transaction or
+arrangement, you convey, or propagate by procuring conveyance of, a
+covered work, and grant a patent license to some of the parties
+receiving the covered work authorizing them to use, propagate, modify
+or convey a specific copy of the covered work, then the patent license
+you grant is automatically extended to all recipients of the covered
+work and works based on it.
+
+  A patent license is "discriminatory" if it does not include within
+the scope of its coverage, prohibits the exercise of, or is
+conditioned on the non-exercise of one or more of the rights that are
+specifically granted under this License.  You may not convey a covered
+work if you are a party to an arrangement with a third party that is
+in the business of distributing software, under which you make payment
+to the third party based on the extent of your activity of conveying
+the work, and under which the third party grants, to any of the
+parties who would receive the covered work from you, a discriminatory
+patent license (a) in connection with copies of the covered work
+conveyed by you (or copies made from those copies), or (b) primarily
+for and in connection with specific products or compilations that
+contain the covered work, unless you entered into that arrangement,
+or that patent license was granted, prior to 28 March 2007.
+
+  Nothing in this License shall be construed as excluding or limiting
+any implied license or other defenses to infringement that may
+otherwise be available to you under applicable patent law.
+
+  12. No Surrender of Others' Freedom.
+
+  If conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License.  If you cannot convey a
+covered work so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you may
+not convey it at all.  For example, if you agree to terms that obligate you
+to collect a royalty for further conveying from those to whom you convey
+the Program, the only way you could satisfy both those terms and this
+License would be to refrain entirely from conveying the Program.
+
+  13. Use with the GNU Affero General Public License.
+
+  Notwithstanding any other provision of this License, you have
+permission to link or combine any covered work with a work licensed
+under version 3 of the GNU Affero General Public License into a single
+combined work, and to convey the resulting work.  The terms of this
+License will continue to apply to the part which is the covered work,
+but the special requirements of the GNU Affero General Public License,
+section 13, concerning interaction through a network will apply to the
+combination as such.
+
+  14. Revised Versions of this License.
+
+  The Free Software Foundation may publish revised and/or new versions of
+the GNU General Public License from time to time.  Such new versions will
+be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.
+
+  Each version is given a distinguishing version number.  If the
+Program specifies that a certain numbered version of the GNU General
+Public License "or any later version" applies to it, you have the
+option of following the terms and conditions either of that numbered
+version or of any later version published by the Free Software
+Foundation.  If the Program does not specify a version number of the
+GNU General Public License, you may choose any version ever published
+by the Free Software Foundation.
+
+  If the Program specifies that a proxy can decide which future
+versions of the GNU General Public License can be used, that proxy's
+public statement of acceptance of a version permanently authorizes you
+to choose that version for the Program.
+
+  Later license versions may give you additional or different
+permissions.  However, no additional obligations are imposed on any
+author or copyright holder as a result of your choosing to follow a
+later version.
+
+  15. Disclaimer of Warranty.
+
+  THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
+APPLICABLE LAW.  EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
+HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY
+OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
+THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
+PURPOSE.  THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM
+IS WITH YOU.  SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
+ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
+
+  16. Limitation of Liability.
+
+  IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
+THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
+GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE
+USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF
+DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
+PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),
+EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF
+SUCH DAMAGES.
+
+  17. Interpretation of Sections 15 and 16.
+
+  If the disclaimer of warranty and limitation of liability provided
+above cannot be given local legal effect according to their terms,
+reviewing courts shall apply local law that most closely approximates
+an absolute waiver of all civil liability in connection with the
+Program, unless a warranty or assumption of liability accompanies a
+copy of the Program in return for a fee.
+
+                     END OF TERMS AND CONDITIONS

+                   GNU LESSER GENERAL PUBLIC LICENSE
+                       Version 3, 29 June 2007
+
+ Copyright (C) 2007 Free Software Foundation, Inc. <https://fsf.org/>
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+
+  This version of the GNU Lesser General Public License incorporates
+the terms and conditions of version 3 of the GNU General Public
+License, supplemented by the additional permissions listed below.
+
+  0. Additional Definitions.
+
+  As used herein, "this License" refers to version 3 of the GNU Lesser
+General Public License, and the "GNU GPL" refers to version 3 of the GNU
+General Public License.
+
+  "The Library" refers to a covered work governed by this License,
+other than an Application or a Combined Work as defined below.
+
+  An "Application" is any work that makes use of an interface provided
+by the Library, but which is not otherwise based on the Library.
+Defining a subclass of a class defined by the Library is deemed a mode
+of using an interface provided by the Library.
+
+  A "Combined Work" is a work produced by combining or linking an
+Application with the Library.  The particular version of the Library
+with which the Combined Work was made is also called the "Linked
+Version".
+
+  The "Minimal Corresponding Source" for a Combined Work means the
+Corresponding Source for the Combined Work, excluding any source code
+for portions of the Combined Work that, considered in isolation, are
+based on the Application, and not on the Linked Version.
+
+  The "Corresponding Application Code" for a Combined Work means the
+object code and/or source code for the Application, including any data
+and utility programs needed for reproducing the Combined Work from the
+Application, but excluding the System Libraries of the Combined Work.
+
+  1. Exception to Section 3 of the GNU GPL.
+
+  You may convey a covered work under sections 3 and 4 of this License
+without being bound by section 3 of the GNU GPL.
+
+  2. Conveying Modified Versions.
+
+  If you modify a copy of the Library, and, in your modifications, a
+facility refers to a function or data to be supplied by an Application
+that uses the facility (other than as an argument passed when the
+facility is invoked), then you may convey a copy of the modified
+version:
+
+   a) under this License, provided that you make a good faith effort to
+   ensure that, in the event an Application does not supply the
+   function or data, the facility still operates, and performs
+   whatever part of its purpose remains meaningful, or
+
+   b) under the GNU GPL, with none of the additional permissions of
+   this License applicable to that copy.
+
+  3. Object Code Incorporating Material from Library Header Files.
+
+  The object code form of an Application may incorporate material from
+a header file that is part of the Library.  You may convey such object
+code under terms of your choice, provided that, if the incorporated
+material is not limited to numerical parameters, data structure
+layouts and accessors, or small macros, inline functions and templates
+(ten or fewer lines in length), you do both of the following:
+
+   a) Give prominent notice with each copy of the object code that the
+   Library is used in it and that the Library and its use are
+   covered by this License.
+
+   b) Accompany the object code with a copy of the GNU GPL and this license
+   document.
+
+  4. Combined Works.
+
+  You may convey a Combined Work under terms of your choice that,
+taken together, effectively do not restrict modification of the
+portions of the Library contained in the Combined Work and reverse
+engineering for debugging such modifications, if you also do each of
+the following:
+
+   a) Give prominent notice with each copy of the Combined Work that
+   the Library is used in it and that the Library and its use are
+   covered by this License.
+
+   b) Accompany the Combined Work with a copy of the GNU GPL and this license
+   document.
+
+   c) For a Combined Work that displays copyright notices during
+   execution, include the copyright notice for the Library among
+   these notices, as well as a reference directing the user to the
+   copies of the GNU GPL and this license document.
+
+   d) Do one of the following:
+
+       0) Convey the Minimal Corresponding Source under the terms of this
+       License, and the Corresponding Application Code in a form
+       suitable for, and under terms that permit, the user to
+       recombine or relink the Application with a modified version of
+       the Linked Version to produce a modified Combined Work, in the
+       manner specified by section 6 of the GNU GPL for conveying
+       Corresponding Source.
+
+       1) Use a suitable shared library mechanism for linking with the
+       Library.  A suitable mechanism is one that (a) uses at run time
+       a copy of the Library already present on the user's computer
+       system, and (b) will operate properly with a modified version
+       of the Library that is interface-compatible with the Linked
+       Version.
+
+   e) Provide Installation Information, but only if you would otherwise
+   be required to provide such information under section 6 of the
+   GNU GPL, and only to the extent that such information is
+   necessary to install and execute a modified version of the
+   Combined Work produced by recombining or relinking the
+   Application with a modified version of the Linked Version. (If
+   you use option 4d0, the Installation Information must accompany
+   the Minimal Corresponding Source and Corresponding Application
+   Code. If you use option 4d1, you must provide the Installation
+   Information in the manner specified by section 6 of the GNU GPL
+   for conveying Corresponding Source.)
+
+  5. Combined Libraries.
+
+  You may place library facilities that are a work based on the
+Library side by side in a single library together with other library
+facilities that are not Applications and are not covered by this
+License, and convey such a combined library under terms of your
+choice, if you do both of the following:
+
+   a) Accompany the combined library with a copy of the same work based
+   on the Library, uncombined with any other library facilities,
+   conveyed under the terms of this License.
+
+   b) Give prominent notice with the combined library that part of it
+   is a work based on the Library, and explaining where to find the
+   accompanying uncombined form of the same work.
+
+  6. Revised Versions of the GNU Lesser General Public License.
+
+  The Free Software Foundation may publish revised and/or new versions
+of the GNU Lesser General Public License from time to time. Such new
+versions will be similar in spirit to the present version, but may
+differ in detail to address new problems or concerns.
+
+  Each version is given a distinguishing version number. If the
+Library as you received it specifies that a certain numbered version
+of the GNU Lesser General Public License "or any later version"
+applies to it, you have the option of following the terms and
+conditions either of that published version or of any later version
+published by the Free Software Foundation. If the Library as you
+received it does not specify a version number of the GNU Lesser
+General Public License, you may choose any version of the GNU Lesser
+General Public License ever published by the Free Software Foundation.
+
+  If the Library as you received it specifies that a proxy can decide
+whether future versions of the GNU Lesser General Public License shall
+apply, that proxy's public statement of acceptance of any version is
+permanent authorization for you to choose that version for the
+Library.

+                    GNU GENERAL PUBLIC LICENSE
+                       Version 3, 29 June 2007
+
+ Copyright (C) 2007 Free Software Foundation, Inc. <https://fsf.org/>
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+                            Preamble
+
+  The GNU General Public License is a free, copyleft license for
+software and other kinds of works.
+
+  The licenses for most software and other practical works are designed
+to take away your freedom to share and change the works.  By contrast,
+the GNU General Public License is intended to guarantee your freedom to
+share and change all versions of a program--to make sure it remains free
+software for all its users.  We, the Free Software Foundation, use the
+GNU General Public License for most of our software; it applies also to
+any other work released this way by its authors.  You can apply it to
+your programs, too.
+
+  When we speak of free software, we are referring to freedom, not
+price.  Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+them if you wish), that you receive source code or can get it if you
+want it, that you can change the software or use pieces of it in new
+free programs, and that you know you can do these things.
+
+  To protect your rights, we need to prevent others from denying you
+these rights or asking you to surrender the rights.  Therefore, you have
+certain responsibilities if you distribute copies of the software, or if
+you modify it: responsibilities to respect the freedom of others.
+
+  For example, if you distribute copies of such a program, whether
+gratis or for a fee, you must pass on to the recipients the same
+freedoms that you received.  You must make sure that they, too, receive
+or can get the source code.  And you must show them these terms so they
+know their rights.
+
+  Developers that use the GNU GPL protect your rights with two steps:
+(1) assert copyright on the software, and (2) offer you this License
+giving you legal permission to copy, distribute and/or modify it.
+
+  For the developers' and authors' protection, the GPL clearly explains
+that there is no warranty for this free software.  For both users' and
+authors' sake, the GPL requires that modified versions be marked as
+changed, so that their problems will not be attributed erroneously to
+authors of previous versions.
+
+  Some devices are designed to deny users access to install or run
+modified versions of the software inside them, although the manufacturer
+can do so.  This is fundamentally incompatible with the aim of
+protecting users' freedom to change the software.  The systematic
+pattern of such abuse occurs in the area of products for individuals to
+use, which is precisely where it is most unacceptable.  Therefore, we
+have designed this version of the GPL to prohibit the practice for those
+products.  If such problems arise substantially in other domains, we
+stand ready to extend this provision to those domains in future versions
+of the GPL, as needed to protect the freedom of users.
+
+  Finally, every program is threatened constantly by software patents.
+States should not allow patents to restrict development and use of
+software on general-purpose computers, but in those that do, we wish to
+avoid the special danger that patents applied to a free program could
+make it effectively proprietary.  To prevent this, the GPL assures that
+patents cannot be used to render the program non-free.
+
+  The precise terms and conditions for copying, distribution and
+modification follow.
+
+                       TERMS AND CONDITIONS
+
+  0. Definitions.
+
+  "This License" refers to version 3 of the GNU General Public License.
+
+  "Copyright" also means copyright-like laws that apply to other kinds of
+works, such as semiconductor masks.
+
+  "The Program" refers to any copyrightable work licensed under this
+License.  Each licensee is addressed as "you".  "Licensees" and
+"recipients" may be individuals or organizations.
+
+  To "modify" a work means to copy from or adapt all or part of the work
+in a fashion requiring copyright permission, other than the making of an
+exact copy.  The resulting work is called a "modified version" of the
+earlier work or a work "based on" the earlier work.
+
+  A "covered work" means either the unmodified Program or a work based
+on the Program.
+
+  To "propagate" a work means to do anything with it that, without
+permission, would make you directly or secondarily liable for
+infringement under applicable copyright law, except executing it on a
+computer or modifying a private copy.  Propagation includes copying,
+distribution (with or without modification), making available to the
+public, and in some countries other activities as well.
+
+  To "convey" a work means any kind of propagation that enables other
+parties to make or receive copies.  Mere interaction with a user through
+a computer network, with no transfer of a copy, is not conveying.
+
+  An interactive user interface displays "Appropriate Legal Notices"
+to the extent that it includes a convenient and prominently visible
+feature that (1) displays an appropriate copyright notice, and (2)
+tells the user that there is no warranty for the work (except to the
+extent that warranties are provided), that licensees may convey the
+work under this License, and how to view a copy of this License.  If
+the interface presents a list of user commands or options, such as a
+menu, a prominent item in the list meets this criterion.
+
+  1. Source Code.
+
+  The "source code" for a work means the preferred form of the work
+for making modifications to it.  "Object code" means any non-source
+form of a work.
+
+  A "Standard Interface" means an interface that either is an official
+standard defined by a recognized standards body, or, in the case of
+interfaces specified for a particular programming language, one that
+is widely used among developers working in that language.
+
+  The "System Libraries" of an executable work include anything, other
+than the work as a whole, that (a) is included in the normal form of
+packaging a Major Component, but which is not part of that Major
+Component, and (b) serves only to enable use of the work with that
+Major Component, or to implement a Standard Interface for which an
+implementation is available to the public in source code form.  A
+"Major Component", in this context, means a major essential component
+(kernel, window system, and so on) of the specific operating system
+(if any) on which the executable work runs, or a compiler used to
+produce the work, or an object code interpreter used to run it.
+
+  The "Corresponding Source" for a work in object code form means all
+the source code needed to generate, install, and (for an executable
+work) run the object code and to modify the work, including scripts to
+control those activities.  However, it does not include the work's
+System Libraries, or general-purpose tools or generally available free
+programs which are used unmodified in performing those activities but
+which are not part of the work.  For example, Corresponding Source
+includes interface definition files associated with source files for
+the work, and the source code for shared libraries and dynamically
+linked subprograms that the work is specifically designed to require,
+such as by intimate data communication or control flow between those
+subprograms and other parts of the work.
+
+  The Corresponding Source need not include anything that users
+can regenerate automatically from other parts of the Corresponding
+Source.
+
+  The Corresponding Source for a work in source code form is that
+same work.
+
+  2. Basic Permissions.
+
+  All rights granted under this License are granted for the term of
+copyright on the Program, and are irrevocable provided the stated
+conditions are met.  This License explicitly affirms your unlimited
+permission to run the unmodified Program.  The output from running a
+covered work is covered by this License only if the output, given its
+content, constitutes a covered work.  This License acknowledges your
+rights of fair use or other equivalent, as provided by copyright law.
+
+  You may make, run and propagate covered works that you do not
+convey, without conditions so long as your license otherwise remains
+in force.  You may convey covered works to others for the sole purpose
+of having them make modifications exclusively for you, or provide you
+with facilities for running those works, provided that you comply with
+the terms of this License in conveying all material for which you do
+not control copyright.  Those thus making or running the covered works
+for you must do so exclusively on your behalf, under your direction
+and control, on terms that prohibit them from making any copies of
+your copyrighted material outside their relationship with you.
+
+  Conveying under any other circumstances is permitted solely under
+the conditions stated below.  Sublicensing is not allowed; section 10
+makes it unnecessary.
+
+  3. Protecting Users' Legal Rights From Anti-Circumvention Law.
+
+  No covered work shall be deemed part of an effective technological
+measure under any applicable law fulfilling obligations under article
+11 of the WIPO copyright treaty adopted on 20 December 1996, or
+similar laws prohibiting or restricting circumvention of such
+measures.
+
+  When you convey a covered work, you waive any legal power to forbid
+circumvention of technological measures to the extent such circumvention
+is effected by exercising rights under this License with respect to
+the covered work, and you disclaim any intention to limit operation or
+modification of the work as a means of enforcing, against the work's
+users, your or third parties' legal rights to forbid circumvention of
+technological measures.
+
+  4. Conveying Verbatim Copies.
+
+  You may convey verbatim copies of the Program's source code as you
+receive it, in any medium, provided that you conspicuously and
+appropriately publish on each copy an appropriate copyright notice;
+keep intact all notices stating that this License and any
+non-permissive terms added in accord with section 7 apply to the code;
+keep intact all notices of the absence of any warranty; and give all
+recipients a copy of this License along with the Program.
+
+  You may charge any price or no price for each copy that you convey,
+and you may offer support or warranty protection for a fee.
+
+  5. Conveying Modified Source Versions.
+
+  You may convey a work based on the Program, or the modifications to
+produce it from the Program, in the form of source code under the
+terms of section 4, provided that you also meet all of these conditions:
+
+    a) The work must carry prominent notices stating that you modified
+    it, and giving a relevant date.
+
+    b) The work must carry prominent notices stating that it is
+    released under this License and any conditions added under section
+    7.  This requirement modifies the requirement in section 4 to
+    "keep intact all notices".
+
+    c) You must license the entire work, as a whole, under this
+    License to anyone who comes into possession of a copy.  This
+    License will therefore apply, along with any applicable section 7
+    additional terms, to the whole of the work, and all its parts,
+    regardless of how they are packaged.  This License gives no
+    permission to license the work in any other way, but it does not
+    invalidate such permission if you have separately received it.
+
+    d) If the work has interactive user interfaces, each must display
+    Appropriate Legal Notices; however, if the Program has interactive
+    interfaces that do not display Appropriate Legal Notices, your
+    work need not make them do so.
+
+  A compilation of a covered work with other separate and independent
+works, which are not by their nature extensions of the covered work,
+and which are not combined with it such as to form a larger program,
+in or on a volume of a storage or distribution medium, is called an
+"aggregate" if the compilation and its resulting copyright are not
+used to limit the access or legal rights of the compilation's users
+beyond what the individual works permit.  Inclusion of a covered work
+in an aggregate does not cause this License to apply to the other
+parts of the aggregate.
+
+  6. Conveying Non-Source Forms.
+
+  You may convey a covered work in object code form under the terms
+of sections 4 and 5, provided that you also convey the
+machine-readable Corresponding Source under the terms of this License,
+in one of these ways:
+
+    a) Convey the object code in, or embodied in, a physical product
+    (including a physical distribution medium), accompanied by the
+    Corresponding Source fixed on a durable physical medium
+    customarily used for software interchange.
+
+    b) Convey the object code in, or embodied in, a physical product
+    (including a physical distribution medium), accompanied by a
+    written offer, valid for at least three years and valid for as
+    long as you offer spare parts or customer support for that product
+    model, to give anyone who possesses the object code either (1) a
+    copy of the Corresponding Source for all the software in the
+    product that is covered by this License, on a durable physical
+    medium customarily used for software interchange, for a price no
+    more than your reasonable cost of physically performing this
+    conveying of source, or (2) access to copy the
+    Corresponding Source from a network server at no charge.
+
+    c) Convey individual copies of the object code with a copy of the
+    written offer to provide the Corresponding Source.  This
+    alternative is allowed only occasionally and noncommercially, and
+    only if you received the object code with such an offer, in accord
+    with subsection 6b.
+
+    d) Convey the object code by offering access from a designated
+    place (gratis or for a charge), and offer equivalent access to the
+    Corresponding Source in the same way through the same place at no
+    further charge.  You need not require recipients to copy the
+    Corresponding Source along with the object code.  If the place to
+    copy the object code is a network server, the Corresponding Source
+    may be on a different server (operated by you or a third party)
+    that supports equivalent copying facilities, provided you maintain
+    clear directions next to the object code saying where to find the
+    Corresponding Source.  Regardless of what server hosts the
+    Corresponding Source, you remain obligated to ensure that it is
+    available for as long as needed to satisfy these requirements.
+
+    e) Convey the object code using peer-to-peer transmission, provided
+    you inform other peers where the object code and Corresponding
+    Source of the work are being offered to the general public at no
+    charge under subsection 6d.
+
+  A separable portion of the object code, whose source code is excluded
+from the Corresponding Source as a System Library, need not be
+included in conveying the object code work.
+
+  A "User Product" is either (1) a "consumer product", which means any
+tangible personal property which is normally used for personal, family,
+or household purposes, or (2) anything designed or sold for incorporation
+into a dwelling.  In determining whether a product is a consumer product,
+doubtful cases shall be resolved in favor of coverage.  For a particular
+product received by a particular user, "normally used" refers to a
+typical or common use of that class of product, regardless of the status
+of the particular user or of the way in which the particular user
+actually uses, or expects or is expected to use, the product.  A product
+is a consumer product regardless of whether the product has substantial
+commercial, industrial or non-consumer uses, unless such uses represent
+the only significant mode of use of the product.
+
+  "Installation Information" for a User Product means any methods,
+procedures, authorization keys, or other information required to install
+and execute modified versions of a covered work in that User Product from
+a modified version of its Corresponding Source.  The information must
+suffice to ensure that the continued functioning of the modified object
+code is in no case prevented or interfered with solely because
+modification has been made.
+
+  If you convey an object code work under this section in, or with, or
+specifically for use in, a User Product, and the conveying occurs as
+part of a transaction in which the right of possession and use of the
+User Product is transferred to the recipient in perpetuity or for a
+fixed term (regardless of how the transaction is characterized), the
+Corresponding Source conveyed under this section must be accompanied
+by the Installation Information.  But this requirement does not apply
+if neither you nor any third party retains the ability to install
+modified object code on the User Product (for example, the work has
+been installed in ROM).
+
+  The requirement to provide Installation Information does not include a
+requirement to continue to provide support service, warranty, or updates
+for a work that has been modified or installed by the recipient, or for
+the User Product in which it has been modified or installed.  Access to a
+network may be denied when the modification itself materially and
+adversely affects the operation of the network or violates the rules and
+protocols for communication across the network.
+
+  Corresponding Source conveyed, and Installation Information provided,
+in accord with this section must be in a format that is publicly
+documented (and with an implementation available to the public in
+source code form), and must require no special password or key for
+unpacking, reading or copying.
+
+  7. Additional Terms.
+
+  "Additional permissions" are terms that supplement the terms of this
+License by making exceptions from one or more of its conditions.
+Additional permissions that are applicable to the entire Program shall
+be treated as though they were included in this License, to the extent
+that they are valid under applicable law.  If additional permissions
+apply only to part of the Program, that part may be used separately
+under those permissions, but the entire Program remains governed by
+this License without regard to the additional permissions.
+
+  When you convey a copy of a covered work, you may at your option
+remove any additional permissions from that copy, or from any part of
+it.  (Additional permissions may be written to require their own
+removal in certain cases when you modify the work.)  You may place
+additional permissions on material, added by you to a covered work,
+for which you have or can give appropriate copyright permission.
+
+  Notwithstanding any other provision of this License, for material you
+add to a covered work, you may (if authorized by the copyright holders of
+that material) supplement the terms of this License with terms:
+
+    a) Disclaiming warranty or limiting liability differently from the
+    terms of sections 15 and 16 of this License; or
+
+    b) Requiring preservation of specified reasonable legal notices or
+    author attributions in that material or in the Appropriate Legal
+    Notices displayed by works containing it; or
+
+    c) Prohibiting misrepresentation of the origin of that material, or
+    requiring that modified versions of such material be marked in
+    reasonable ways as different from the original version; or
+
+    d) Limiting the use for publicity purposes of names of licensors or
+    authors of the material; or
+
+    e) Declining to grant rights under trademark law for use of some
+    trade names, trademarks, or service marks; or
+
+    f) Requiring indemnification of licensors and authors of that
+    material by anyone who conveys the material (or modified versions of
+    it) with contractual assumptions of liability to the recipient, for
+    any liability that these contractual assumptions directly impose on
+    those licensors and authors.
+
+  All other non-permissive additional terms are considered "further
+restrictions" within the meaning of section 10.  If the Program as you
+received it, or any part of it, contains a notice stating that it is
+governed by this License along with a term that is a further
+restriction, you may remove that term.  If a license document contains
+a further restriction but permits relicensing or conveying under this
+License, you may add to a covered work material governed by the terms
+of that license document, provided that the further restriction does
+not survive such relicensing or conveying.
+
+  If you add terms to a covered work in accord with this section, you
+must place, in the relevant source files, a statement of the
+additional terms that apply to those files, or a notice indicating
+where to find the applicable terms.
+
+  Additional terms, permissive or non-permissive, may be stated in the
+form of a separately written license, or stated as exceptions;
+the above requirements apply either way.
+
+  8. Termination.
+
+  You may not propagate or modify a covered work except as expressly
+provided under this License.  Any attempt otherwise to propagate or
+modify it is void, and will automatically terminate your rights under
+this License (including any patent licenses granted under the third
+paragraph of section 11).
+
+  However, if you cease all violation of this License, then your
+license from a particular copyright holder is reinstated (a)
+provisionally, unless and until the copyright holder explicitly and
+finally terminates your license, and (b) permanently, if the copyright
+holder fails to notify you of the violation by some reasonable means
+prior to 60 days after the cessation.
+
+  Moreover, your license from a particular copyright holder is
+reinstated permanently if the copyright holder notifies you of the
+violation by some reasonable means, this is the first time you have
+received notice of violation of this License (for any work) from that
+copyright holder, and you cure the violation prior to 30 days after
+your receipt of the notice.
+
+  Termination of your rights under this section does not terminate the
+licenses of parties who have received copies or rights from you under
+this License.  If your rights have been terminated and not permanently
+reinstated, you do not qualify to receive new licenses for the same
+material under section 10.
+
+  9. Acceptance Not Required for Having Copies.
+
+  You are not required to accept this License in order to receive or
+run a copy of the Program.  Ancillary propagation of a covered work
+occurring solely as a consequence of using peer-to-peer transmission
+to receive a copy likewise does not require acceptance.  However,
+nothing other than this License grants you permission to propagate or
+modify any covered work.  These actions infringe copyright if you do
+not accept this License.  Therefore, by modifying or propagating a
+covered work, you indicate your acceptance of this License to do so.
+
+  10. Automatic Licensing of Downstream Recipients.
+
+  Each time you convey a covered work, the recipient automatically
+receives a license from the original licensors, to run, modify and
+propagate that work, subject to this License.  You are not responsible
+for enforcing compliance by third parties with this License.
+
+  An "entity transaction" is a transaction transferring control of an
+organization, or substantially all assets of one, or subdividing an
+organization, or merging organizations.  If propagation of a covered
+work results from an entity transaction, each party to that
+transaction who receives a copy of the work also receives whatever
+licenses to the work the party's predecessor in interest had or could
+give under the previous paragraph, plus a right to possession of the
+Corresponding Source of the work from the predecessor in interest, if
+the predecessor has it or can get it with reasonable efforts.
+
+  You may not impose any further restrictions on the exercise of the
+rights granted or affirmed under this License.  For example, you may
+not impose a license fee, royalty, or other charge for exercise of
+rights granted under this License, and you may not initiate litigation
+(including a cross-claim or counterclaim in a lawsuit) alleging that
+any patent claim is infringed by making, using, selling, offering for
+sale, or importing the Program or any portion of it.
+
+  11. Patents.
+
+  A "contributor" is a copyright holder who authorizes use under this
+License of the Program or a work on which the Program is based.  The
+work thus licensed is called the contributor's "contributor version".
+
+  A contributor's "essential patent claims" are all patent claims
+owned or controlled by the contributor, whether already acquired or
+hereafter acquired, that would be infringed by some manner, permitted
+by this License, of making, using, or selling its contributor version,
+but do not include claims that would be infringed only as a
+consequence of further modification of the contributor version.  For
+purposes of this definition, "control" includes the right to grant
+patent sublicenses in a manner consistent with the requirements of
+this License.
+
+  Each contributor grants you a non-exclusive, worldwide, royalty-free
+patent license under the contributor's essential patent claims, to
+make, use, sell, offer for sale, import and otherwise run, modify and
+propagate the contents of its contributor version.
+
+  In the following three paragraphs, a "patent license" is any express
+agreement or commitment, however denominated, not to enforce a patent
+(such as an express permission to practice a patent or covenant not to
+sue for patent infringement).  To "grant" such a patent license to a
+party means to make such an agreement or commitment not to enforce a
+patent against the party.
+
+  If you convey a covered work, knowingly relying on a patent license,
+and the Corresponding Source of the work is not available for anyone
+to copy, free of charge and under the terms of this License, through a
+publicly available network server or other readily accessible means,
+then you must either (1) cause the Corresponding Source to be so
+available, or (2) arrange to deprive yourself of the benefit of the
+patent license for this particular work, or (3) arrange, in a manner
+consistent with the requirements of this License, to extend the patent
+license to downstream recipients.  "Knowingly relying" means you have
+actual knowledge that, but for the patent license, your conveying the
+covered work in a country, or your recipient's use of the covered work
+in a country, would infringe one or more identifiable patents in that
+country that you have reason to believe are valid.
+
+  If, pursuant to or in connection with a single transaction or
+arrangement, you convey, or propagate by procuring conveyance of, a
+covered work, and grant a patent license to some of the parties
+receiving the covered work authorizing them to use, propagate, modify
+or convey a specific copy of the covered work, then the patent license
+you grant is automatically extended to all recipients of the covered
+work and works based on it.
+
+  A patent license is "discriminatory" if it does not include within
+the scope of its coverage, prohibits the exercise of, or is
+conditioned on the non-exercise of one or more of the rights that are
+specifically granted under this License.  You may not convey a covered
+work if you are a party to an arrangement with a third party that is
+in the business of distributing software, under which you make payment
+to the third party based on the extent of your activity of conveying
+the work, and under which the third party grants, to any of the
+parties who would receive the covered work from you, a discriminatory
+patent license (a) in connection with copies of the covered work
+conveyed by you (or copies made from those copies), or (b) primarily
+for and in connection with specific products or compilations that
+contain the covered work, unless you entered into that arrangement,
+or that patent license was granted, prior to 28 March 2007.
+
+  Nothing in this License shall be construed as excluding or limiting
+any implied license or other defenses to infringement that may
+otherwise be available to you under applicable patent law.
+
+  12. No Surrender of Others' Freedom.
+
+  If conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License.  If you cannot convey a
+covered work so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you may
+not convey it at all.  For example, if you agree to terms that obligate you
+to collect a royalty for further conveying from those to whom you convey
+the Program, the only way you could satisfy both those terms and this
+License would be to refrain entirely from conveying the Program.
+
+  13. Use with the GNU Affero General Public License.
+
+  Notwithstanding any other provision of this License, you have
+permission to link or combine any covered work with a work licensed
+under version 3 of the GNU Affero General Public License into a single
+combined work, and to convey the resulting work.  The terms of this
+License will continue to apply to the part which is the covered work,
+but the special requirements of the GNU Affero General Public License,
+section 13, concerning interaction through a network will apply to the
+combination as such.
+
+  14. Revised Versions of this License.
+
+  The Free Software Foundation may publish revised and/or new versions of
+the GNU General Public License from time to time.  Such new versions will
+be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.
+
+  Each version is given a distinguishing version number.  If the
+Program specifies that a certain numbered version of the GNU General
+Public License "or any later version" applies to it, you have the
+option of following the terms and conditions either of that numbered
+version or of any later version published by the Free Software
+Foundation.  If the Program does not specify a version number of the
+GNU General Public License, you may choose any version ever published
+by the Free Software Foundation.
+
+  If the Program specifies that a proxy can decide which future
+versions of the GNU General Public License can be used, that proxy's
+public statement of acceptance of a version permanently authorizes you
+to choose that version for the Program.
+
+  Later license versions may give you additional or different
+permissions.  However, no additional obligations are imposed on any
+author or copyright holder as a result of your choosing to follow a
+later version.
+
+  15. Disclaimer of Warranty.
+
+  THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
+APPLICABLE LAW.  EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
+HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY
+OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
+THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
+PURPOSE.  THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM
+IS WITH YOU.  SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
+ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
+
+  16. Limitation of Liability.
+
+  IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
+THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY

+EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF
+SUCH DAMAGES.
+
+  17. Interpretation of Sections 15 and 16.
+
+  If the disclaimer of warranty and limitation of liability provided
+above cannot be given local legal effect according to their terms,
+reviewing courts shall apply local law that most closely approximates
+an absolute waiver of all civil liability in connection with the
+Program, unless a warranty or assumption of liability accompanies a
+copy of the Program in return for a fee.

+                   GNU LESSER GENERAL PUBLIC LICENSE
+                       Version 3, 29 June 2007
+
+ Copyright (C) 2007 Free Software Foundation, Inc. <https://fsf.org/>
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+
+  This version of the GNU Lesser General Public License incorporates
+the terms and conditions of version 3 of the GNU General Public
+License, supplemented by the additional permissions listed below.
+
+  0. Additional Definitions.
+
+  As used herein, "this License" refers to version 3 of the GNU Lesser
+General Public License, and the "GNU GPL" refers to version 3 of the GNU
+General Public License.
+
+  "The Library" refers to a covered work governed by this License,
+other than an Application or a Combined Work as defined below.
+
+  An "Application" is any work that makes use of an interface provided
+by the Library, but which is not otherwise based on the Library.
+Defining a subclass of a class defined by the Library is deemed a mode
+of using an interface provided by the Library.
+
+  A "Combined Work" is a work produced by combining or linking an
+Application with the Library.  The particular version of the Library
+with which the Combined Work was made is also called the "Linked
+Version".
+
+  The "Minimal Corresponding Source" for a Combined Work means the
+Corresponding Source for the Combined Work, excluding any source code
+for portions of the Combined Work that, considered in isolation, are
+based on the Application, and not on the Linked Version.
+
+  The "Corresponding Application Code" for a Combined Work means the
+object code and/or source code for the Application, including any data
+and utility programs needed for reproducing the Combined Work from the
+Application, but excluding the System Libraries of the Combined Work.
+
+  1. Exception to Section 3 of the GNU GPL.
+
+  You may convey a covered work under sections 3 and 4 of this License
+without being bound by section 3 of the GNU GPL.
+
+  2. Conveying Modified Versions.
+
+  If you modify a copy of the Library, and, in your modifications, a
+facility refers to a function or data to be supplied by an Application
+that uses the facility (other than as an argument passed when the
+facility is invoked), then you may convey a copy of the modified
+version:
+
+   a) under this License, provided that you make a good faith effort to
+   ensure that, in the event an Application does not supply the
+   function or data, the facility still operates, and performs
+   whatever part of its purpose remains meaningful, or
+
+   b) under the GNU GPL, with none of the additional permissions of
+   this License applicable to that copy.
+
+  3. Object Code Incorporating Material from Library Header Files.
+
+  The object code form of an Application may incorporate material from
+a header file that is part of the Library.  You may convey such object
+code under terms of your choice, provided that, if the incorporated
+material is not limited to numerical parameters, data structure
+layouts and accessors, or small macros, inline functions and templates
+(ten or fewer lines in length), you do both of the following:
+
+   a) Give prominent notice with each copy of the object code that the
+   Library is used in it and that the Library and its use are
+   covered by this License.
+
+   b) Accompany the object code with a copy of the GNU GPL and this license
+   document.
+
+  4. Combined Works.
+
+  You may convey a Combined Work under terms of your choice that,
+taken together, effectively do not restrict modification of the
+portions of the Library contained in the Combined Work and reverse
+engineering for debugging such modifications, if you also do each of
+the following:
+
+   a) Give prominent notice with each copy of the Combined Work that
+   the Library is used in it and that the Library and its use are
+   covered by this License.
+
+   b) Accompany the Combined Work with a copy of the GNU GPL and this license
+   document.
+
+   c) For a Combined Work that displays copyright notices during
+   execution, include the copyright notice for the Library among
+   these notices, as well as a reference directing the user to the
+   copies of the GNU GPL and this license document.
+
+   d) Do one of the following:
+
+       0) Convey the Minimal Corresponding Source under the terms of this
+       License, and the Corresponding Application Code in a form
+       suitable for, and under terms that permit, the user to
+       recombine or relink the Application with a modified version of
+       the Linked Version to produce a modified Combined Work, in the
+       manner specified by section 6 of the GNU GPL for conveying
+       Corresponding Source.
+
+       1) Use a suitable shared library mechanism for linking with the
+       Library.  A suitable mechanism is one that (a) uses at run time
+       a copy of the Library already present on the user's computer
+       system, and (b) will operate properly with a modified version
+       of the Library that is interface-compatible with the Linked
+       Version.
+
+   e) Provide Installation Information, but only if you would otherwise
+   be required to provide such information under section 6 of the
+   GNU GPL, and only to the extent that such information is
+   necessary to install and execute a modified version of the
+   Combined Work produced by recombining or relinking the
+   Application with a modified version of the Linked Version. (If
+   you use option 4d0, the Installation Information must accompany
+   the Minimal Corresponding Source and Corresponding Application
+   Code. If you use option 4d1, you must provide the Installation
+   Information in the manner specified by section 6 of the GNU GPL
+   for conveying Corresponding Source.)
+
+  5. Combined Libraries.
+
+  You may place library facilities that are a work based on the
+Library side by side in a single library together with other library
+facilities that are not Applications and are not covered by this
+License, and convey such a combined library under terms of your
+choice, if you do both of the following:
+
+   a) Accompany the combined library with a copy of the same work based
+   on the Library, uncombined with any other library facilities,
+   conveyed under the terms of this License.
+
+   b) Give prominent notice with the combined library that part of it
+   is a work based on the Library, and explaining where to find the
+   accompanying uncombined form of the same work.
+
+  6. Revised Versions of the GNU Lesser General Public License.
+
+  The Free Software Foundation may publish revised and/or new versions
+of the GNU Lesser General Public License from time to time. Such new
+versions will be similar in spirit to the present version, but may
+differ in detail to address new problems or concerns.
+
+  Each version is given a distinguishing version number. If the
+Library as you received it specifies that a certain numbered version
+of the GNU Lesser General Public License "or any later version"
+applies to it, you have the option of following the terms and
+conditions either of that published version or of any later version
+published by the Free Software Foundation. If the Library as you
+received it does not specify a version number of the GNU Lesser
+General Public License, you may choose any version of the GNU Lesser
+General Public License ever published by the Free Software Foundation.
+
+  If the Library as you received it specifies that a proxy can decide
+whether future versions of the GNU Lesser General Public License shall
+apply, that proxy's public statement of acceptance of any version is
+permanent authorization for you to choose that version for the
+Library.

+                    GNU GENERAL PUBLIC LICENSE
+                       Version 3, 29 June 2007
+
+ Copyright (C) 2007 Free Software Foundation, Inc. <https://fsf.org/>
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+                            Preamble
+
+  The GNU General Public License is a free, copyleft license for
+software and other kinds of works.
+
+  The licenses for most software and other practical works are designed
+to take away your freedom to share and change the works.  By contrast,
+the GNU General Public License is intended to guarantee your freedom to
+share and change all versions of a program--to make sure it remains free
+software for all its users.  We, the Free Software Foundation, use the
+GNU General Public License for most of our software; it applies also to
+any other work released this way by its authors.  You can apply it to
+your programs, too.
+
+  When we speak of free software, we are referring to freedom, not
+price.  Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+them if you wish), that you receive source code or can get it if you
+want it, that you can change the software or use pieces of it in new
+free programs, and that you know you can do these things.
+
+  To protect your rights, we need to prevent others from denying you
+these rights or asking you to surrender the rights.  Therefore, you have
+certain responsibilities if you distribute copies of the software, or if
+you modify it: responsibilities to respect the freedom of others.
+
+  For example, if you distribute copies of such a program, whether
+gratis or for a fee, you must pass on to the recipients the same
+freedoms that you received.  You must make sure that they, too, receive
+or can get the source code.  And you must show them these terms so they
+know their rights.
+
+  Developers that use the GNU GPL protect your rights with two steps:
+(1) assert copyright on the software, and (2) offer you this License
+giving you legal permission to copy, distribute and/or modify it.
+
+  For the developers' and authors' protection, the GPL clearly explains
+that there is no warranty for this free software.  For both users' and
+authors' sake, the GPL requires that modified versions be marked as
+changed, so that their problems will not be attributed erroneously to
+authors of previous versions.
+
+  Some devices are designed to deny users access to install or run
+modified versions of the software inside them, although the manufacturer
+can do so.  This is fundamentally incompatible with the aim of
+protecting users' freedom to change the software.  The systematic
+pattern of such abuse occurs in the area of products for individuals to
+use, which is precisely where it is most unacceptable.  Therefore, we
+have designed this version of the GPL to prohibit the practice for those
+products.  If such problems arise substantially in other domains, we
+stand ready to extend this provision to those domains in future versions
+of the GPL, as needed to protect the freedom of users.
+
+  Finally, every program is threatened constantly by software patents.
+States should not allow patents to restrict development and use of
+software on general-purpose computers, but in those that do, we wish to
+avoid the special danger that patents applied to a free program could
+make it effectively proprietary.  To prevent this, the GPL assures that
+patents cannot be used to render the program non-free.
+
+  The precise terms and conditions for copying, distribution and
+modification follow.
+
+                       TERMS AND CONDITIONS
+
+  0. Definitions.
+
+  "This License" refers to version 3 of the GNU General Public License.
+
+  "Copyright" also means copyright-like laws that apply to other kinds of
+works, such as semiconductor masks.
+
+  "The Program" refers to any copyrightable work licensed under this
+License.  Each licensee is addressed as "you".  "Licensees" and
+"recipients" may be individuals or organizations.
+
+  To "modify" a work means to copy from or adapt all or part of the work
+in a fashion requiring copyright permission, other than the making of an
+exact copy.  The resulting work is called a "modified version" of the
+earlier work or a work "based on" the earlier work.
+
+  A "covered work" means either the unmodified Program or a work based
+on the Program.
+
+  To "propagate" a work means to do anything with it that, without
+permission, would make you directly or secondarily liable for
+infringement under applicable copyright law, except executing it on a
+computer or modifying a private copy.  Propagation includes copying,
+distribution (with or without modification), making available to the
+public, and in some countries other activities as well.
+
+  To "convey" a work means any kind of propagation that enables other
+parties to make or receive copies.  Mere interaction with a user through
+a computer network, with no transfer of a copy, is not conveying.
+
+  An interactive user interface displays "Appropriate Legal Notices"
+to the extent that it includes a convenient and prominently visible
+feature that (1) displays an appropriate copyright notice, and (2)
+tells the user that there is no warranty for the work (except to the
+extent that warranties are provided), that licensees may convey the
+work under this License, and how to view a copy of this License.  If
+the interface presents a list of user commands or options, such as a
+menu, a prominent item in the list meets this criterion.
+
+  1. Source Code.
+
+  The "source code" for a work means the preferred form of the work
+for making modifications to it.  "Object code" means any non-source
+form of a work.
+
+  A "Standard Interface" means an interface that either is an official
+standard defined by a recognized standards body, or, in the case of
+interfaces specified for a particular programming language, one that
+is widely used among developers working in that language.
+
+  The "System Libraries" of an executable work include anything, other
+than the work as a whole, that (a) is included in the normal form of
+packaging a Major Component, but which is not part of that Major
+Component, and (b) serves only to enable use of the work with that
+Major Component, or to implement a Standard Interface for which an
+implementation is available to the public in source code form.  A
+"Major Component", in this context, means a major essential component
+(kernel, window system, and so on) of the specific operating system
+(if any) on which the executable work runs, or a compiler used to
+produce the work, or an object code interpreter used to run it.
+
+  The "Corresponding Source" for a work in object code form means all
+the source code needed to generate, install, and (for an executable
+work) run the object code and to modify the work, including scripts to
+control those activities.  However, it does not include the work's
+System Libraries, or general-purpose tools or generally available free
+programs which are used unmodified in performing those activities but
+which are not part of the work.  For example, Corresponding Source
+includes interface definition files associated with source files for
+the work, and the source code for shared libraries and dynamically
+linked subprograms that the work is specifically designed to require,
+such as by intimate data communication or control flow between those
+subprograms and other parts of the work.
+
+  The Corresponding Source need not include anything that users
+can regenerate automatically from other parts of the Corresponding
+Source.
+
+  The Corresponding Source for a work in source code form is that
+same work.
+
+  2. Basic Permissions.
+
+  All rights granted under this License are granted for the term of
+copyright on the Program, and are irrevocable provided the stated
+conditions are met.  This License explicitly affirms your unlimited
+permission to run the unmodified Program.  The output from running a
+covered work is covered by this License only if the output, given its
+content, constitutes a covered work.  This License acknowledges your
+rights of fair use or other equivalent, as provided by copyright law.
+
+  You may make, run and propagate covered works that you do not
+convey, without conditions so long as your license otherwise remains
+in force.  You may convey covered works to others for the sole purpose
+of having them make modifications exclusively for you, or provide you
+with facilities for running those works, provided that you comply with
+the terms of this License in conveying all material for which you do
+not control copyright.  Those thus making or running the covered works
+for you must do so exclusively on your behalf, under your direction
+and control, on terms that prohibit them from making any copies of
+your copyrighted material outside their relationship with you.
+
+  Conveying under any other circumstances is permitted solely under
+the conditions stated below.  Sublicensing is not allowed; section 10
+makes it unnecessary.
+
+  3. Protecting Users' Legal Rights From Anti-Circumvention Law.
+
+  No covered work shall be deemed part of an effective technological
+measure under any applicable law fulfilling obligations under article
+11 of the WIPO copyright treaty adopted on 20 December 1996, or
+similar laws prohibiting or restricting circumvention of such
+measures.
+
+  When you convey a covered work, you waive any legal power to forbid
+circumvention of technological measures to the extent such circumvention
+is effected by exercising rights under this License with respect to
+the covered work, and you disclaim any intention to limit operation or
+modification of the work as a means of enforcing, against the work's
+users, your or third parties' legal rights to forbid circumvention of
+technological measures.
+
+  4. Conveying Verbatim Copies.
+
+  You may convey verbatim copies of the Program's source code as you
+receive it, in any medium, provided that you conspicuously and
+appropriately publish on each copy an appropriate copyright notice;
+keep intact all notices stating that this License and any
+non-permissive terms added in accord with section 7 apply to the code;
+keep intact all notices of the absence of any warranty; and give all
+recipients a copy of this License along with the Program.
+
+  You may charge any price or no price for each copy that you convey,
+and you may offer support or warranty protection for a fee.
+
+  5. Conveying Modified Source Versions.
+
+  You may convey a work based on the Program, or the modifications to
+produce it from the Program, in the form of source code under the
+terms of section 4, provided that you also meet all of these conditions:
+
+    a) The work must carry prominent notices stating that you modified
+    it, and giving a relevant date.
+
+    b) The work must carry prominent notices stating that it is
+    released under this License and any conditions added under section
+    7.  This requirement modifies the requirement in section 4 to
+    "keep intact all notices".
+
+    c) You must license the entire work, as a whole, under this
+    License to anyone who comes into possession of a copy.  This
+    License will therefore apply, along with any applicable section 7
+    additional terms, to the whole of the work, and all its parts,
+    regardless of how they are packaged.  This License gives no
+    permission to license the work in any other way, but it does not
+    invalidate such permission if you have separately received it.
+
+    d) If the work has interactive user interfaces, each must display
+    Appropriate Legal Notices; however, if the Program has interactive
+    interfaces that do not display Appropriate Legal Notices, your
+    work need not make them do so.
+
+  A compilation of a covered work with other separate and independent
+works, which are not by their nature extensions of the covered work,
+and which are not combined with it such as to form a larger program,
+in or on a volume of a storage or distribution medium, is called an
+"aggregate" if the compilation and its resulting copyright are not
+used to limit the access or legal rights of the compilation's users
+beyond what the individual works permit.  Inclusion of a covered work
+in an aggregate does not cause this License to apply to the other
+parts of the aggregate.
+
+  6. Conveying Non-Source Forms.
+
+  You may convey a covered work in object code form under the terms
+of sections 4 and 5, provided that you also convey the
+machine-readable Corresponding Source under the terms of this License,
+in one of these ways:
+
+    a) Convey the object code in, or embodied in, a physical product
+    (including a physical distribution medium), accompanied by the
+    Corresponding Source fixed on a durable physical medium
+    customarily used for software interchange.
+
+    b) Convey the object code in, or embodied in, a physical product
+    (including a physical distribution medium), accompanied by a
+    written offer, valid for at least three years and valid for as
+    long as you offer spare parts or customer support for that product
+    model, to give anyone who possesses the object code either (1) a
+    copy of the Corresponding Source for all the software in the
+    product that is covered by this License, on a durable physical
+    medium customarily used for software interchange, for a price no
+    more than your reasonable cost of physically performing this
+    conveying of source, or (2) access to copy the
+    Corresponding Source from a network server at no charge.
+
+    c) Convey individual copies of the object code with a copy of the
+    written offer to provide the Corresponding Source.  This
+    alternative is allowed only occasionally and noncommercially, and
+    only if you received the object code with such an offer, in accord
+    with subsection 6b.
+
+    d) Convey the object code by offering access from a designated
+    place (gratis or for a charge), and offer equivalent access to the
+    Corresponding Source in the same way through the same place at no
+    further charge.  You need not require recipients to copy the
+    Corresponding Source along with the object code.  If the place to
+    copy the object code is a network server, the Corresponding Source
+    may be on a different server (operated by you or a third party)
+    that supports equivalent copying facilities, provided you maintain
+    clear directions next to the object code saying where to find the
+    Corresponding Source.  Regardless of what server hosts the
+    Corresponding Source, you remain obligated to ensure that it is
+    available for as long as needed to satisfy these requirements.
+
+    e) Convey the object code using peer-to-peer transmission, provided
+    you inform other peers where the object code and Corresponding
+    Source of the work are being offered to the general public at no
+    charge under subsection 6d.
+
+  A separable portion of the object code, whose source code is excluded
+from the Corresponding Source as a System Library, need not be
+included in conveying the object code work.
+
+  A "User Product" is either (1) a "consumer product", which means any
+tangible personal property which is normally used for personal, family,
+or household purposes, or (2) anything designed or sold for incorporation
+into a dwelling.  In determining whether a product is a consumer product,
+doubtful cases shall be resolved in favor of coverage.  For a particular
+product received by a particular user, "normally used" refers to a
+typical or common use of that class of product, regardless of the status
+of the particular user or of the way in which the particular user
+actually uses, or expects or is expected to use, the product.  A product
+is a consumer product regardless of whether the product has substantial
+commercial, industrial or non-consumer uses, unless such uses represent
+the only significant mode of use of the product.
+
+  "Installation Information" for a User Product means any methods,
+procedures, authorization keys, or other information required to install
+and execute modified versions of a covered work in that User Product from
+a modified version of its Corresponding Source.  The information must
+suffice to ensure that the continued functioning of the modified object
+code is in no case prevented or interfered with solely because
+modification has been made.
+
+  If you convey an object code work under this section in, or with, or
+specifically for use in, a User Product, and the conveying occurs as
+part of a transaction in which the right of possession and use of the
+User Product is transferred to the recipient in perpetuity or for a
+fixed term (regardless of how the transaction is characterized), the
+Corresponding Source conveyed under this section must be accompanied
+by the Installation Information.  But this requirement does not apply
+if neither you nor any third party retains the ability to install
+modified object code on the User Product (for example, the work has
+been installed in ROM).
+
+  The requirement to provide Installation Information does not include a
+requirement to continue to provide support service, warranty, or updates
+for a work that has been modified or installed by the recipient, or for
+the User Product in which it has been modified or installed.  Access to a
+network may be denied when the modification itself materially and
+adversely affects the operation of the network or violates the rules and
+protocols for communication across the network.
+
+  Corresponding Source conveyed, and Installation Information provided,
+in accord with this section must be in a format that is publicly
+documented (and with an implementation available to the public in
+source code form), and must require no special password or key for
+unpacking, reading or copying.
+
+  7. Additional Terms.
+
+  "Additional permissions" are terms that supplement the terms of this
+License by making exceptions from one or more of its conditions.
+Additional permissions that are applicable to the entire Program shall
+be treated as though they were included in this License, to the extent
+that they are valid under applicable law.  If additional permissions
+apply only to part of the Program, that part may be used separately
+under those permissions, but the entire Program remains governed by
+this License without regard to the additional permissions.
+
+  When you convey a copy of a covered work, you may at your option
+remove any additional permissions from that copy, or from any part of
+it.  (Additional permissions may be written to require their own
+removal in certain cases when you modify the work.)  You may place
+additional permissions on material, added by you to a covered work,
+for which you have or can give appropriate copyright permission.
+
+  Notwithstanding any other provision of this License, for material you
+add to a covered work, you may (if authorized by the copyright holders of
+that material) supplement the terms of this License with terms:
+
+    a) Disclaiming warranty or limiting liability differently from the
+    terms of sections 15 and 16 of this License; or
+
+    b) Requiring preservation of specified reasonable legal notices or
+    author attributions in that material or in the Appropriate Legal
+    Notices displayed by works containing it; or
+
+    c) Prohibiting misrepresentation of the origin of that material, or
+    requiring that modified versions of such material be marked in
+    reasonable ways as different from the original version; or
+
+    d) Limiting the use for publicity purposes of names of licensors or
+    authors of the material; or
+
+    e) Declining to grant rights under trademark law for use of some
+    trade names, trademarks, or service marks; or
+
+    f) Requiring indemnification of licensors and authors of that
+    material by anyone who conveys the material (or modified versions of
+    it) with contractual assumptions of liability to the recipient, for
+    any liability that these contractual assumptions directly impose on
+    those licensors and authors.
+
+  All other non-permissive additional terms are considered "further
+restrictions" within the meaning of section 10.  If the Program as you
+received it, or any part of it, contains a notice stating that it is
+governed by this License along with a term that is a further
+restriction, you may remove that term.  If a license document contains
+a further restriction but permits relicensing or conveying under this
+License, you may add to a covered work material governed by the terms
+of that license document, provided that the further restriction does
+not survive such relicensing or conveying.
+
+  If you add terms to a covered work in accord with this section, you
+must place, in the relevant source files, a statement of the
+additional terms that apply to those files, or a notice indicating
+where to find the applicable terms.
+
+  Additional terms, permissive or non-permissive, may be stated in the
+form of a separately written license, or stated as exceptions;
+the above requirements apply either way.
+
+  8. Termination.
+
+  You may not propagate or modify a covered work except as expressly
+provided under this License.  Any attempt otherwise to propagate or
+modify it is void, and will automatically terminate your rights under
+this License (including any patent licenses granted under the third
+paragraph of section 11).
+
+  However, if you cease all violation of this License, then your
+license from a particular copyright holder is reinstated (a)
+provisionally, unless and until the copyright holder explicitly and
+finally terminates your license, and (b) permanently, if the copyright
+holder fails to notify you of the violation by some reasonable means
+prior to 60 days after the cessation.
+
+  Moreover, your license from a particular copyright holder is
+reinstated permanently if the copyright holder notifies you of the
+violation by some reasonable means, this is the first time you have
+received notice of violation of this License (for any work) from that
+copyright holder, and you cure the violation prior to 30 days after
+your receipt of the notice.
+
+  Termination of your rights under this section does not terminate the
+licenses of parties who have received copies or rights from you under
+this License.  If your rights have been terminated and not permanently
+reinstated, you do not qualify to receive new licenses for the same
+material under section 10.
+
+  9. Acceptance Not Required for Having Copies.
+
+  You are not required to accept this License in order to receive or
+run a copy of the Program.  Ancillary propagation of a covered work
+occurring solely as a consequence of using peer-to-peer transmission
+to receive a copy likewise does not require acceptance.  However,
+nothing other than this License grants you permission to propagate or
+modify any covered work.  These actions infringe copyright if you do
+not accept this License.  Therefore, by modifying or propagating a
+covered work, you indicate your acceptance of this License to do so.
+
+  10. Automatic Licensing of Downstream Recipients.
+
+  Each time you convey a covered work, the recipient automatically
+receives a license from the original licensors, to run, modify and
+propagate that work, subject to this License.  You are not responsible
+for enforcing compliance by third parties with this License.
+
+  An "entity transaction" is a transaction transferring control of an
+organization, or substantially all assets of one, or subdividing an
+organization, or merging organizations.  If propagation of a covered
+work results from an entity transaction, each party to that
+transaction who receives a copy of the work also receives whatever
+licenses to the work the party's predecessor in interest had or could
+give under the previous paragraph, plus a right to possession of the
+Corresponding Source of the work from the predecessor in interest, if
+the predecessor has it or can get it with reasonable efforts.
+
+  You may not impose any further restrictions on the exercise of the
+rights granted or affirmed under this License.  For example, you may
+not impose a license fee, royalty, or other charge for exercise of
+rights granted under this License, and you may not initiate litigation
+(including a cross-claim or counterclaim in a lawsuit) alleging that
+any patent claim is infringed by making, using, selling, offering for
+sale, or importing the Program or any portion of it.
+
+  11. Patents.
+
+  A "contributor" is a copyright holder who authorizes use under this
+License of the Program or a work on which the Program is based.  The
+work thus licensed is called the contributor's "contributor version".
+
+  A contributor's "essential patent claims" are all patent claims
+owned or controlled by the contributor, whether already acquired or
+hereafter acquired, that would be infringed by some manner, permitted
+by this License, of making, using, or selling its contributor version,
+but do not include claims that would be infringed only as a
+consequence of further modification of the contributor version.  For
+purposes of this definition, "control" includes the right to grant
+patent sublicenses in a manner consistent with the requirements of
+this License.
+
+  Each contributor grants you a non-exclusive, worldwide, royalty-free
+patent license under the contributor's essential patent claims, to
+make, use, sell, offer for sale, import and otherwise run, modify and
+propagate the contents of its contributor version.
+
+  In the following three paragraphs, a "patent license" is any express
+agreement or commitment, however denominated, not to enforce a patent
+(such as an express permission to practice a patent or covenant not to
+sue for patent infringement).  To "grant" such a patent license to a
+party means to make such an agreement or commitment not to enforce a
+patent against the party.
+
+  If you convey a covered work, knowingly relying on a patent license,
+and the Corresponding Source of the work is not available for anyone
+to copy, free of charge and under the terms of this License, through a
+publicly available network server or other readily accessible means,
+then you must either (1) cause the Corresponding Source to be so
+available, or (2) arrange to deprive yourself of the benefit of the
+patent license for this particular work, or (3) arrange, in a manner
+consistent with the requirements of this License, to extend the patent
+license to downstream recipients.  "Knowingly relying" means you have
+actual knowledge that, but for the patent license, your conveying the
+covered work in a country, or your recipient's use of the covered work
+in a country, would infringe one or more identifiable patents in that
+country that you have reason to believe are valid.
+
+  If, pursuant to or in connection with a single transaction or
+arrangement, you convey, or propagate by procuring conveyance of, a
+covered work, and grant a patent license to some of the parties
+receiving the covered work authorizing them to use, propagate, modify
+or convey a specific copy of the covered work, then the patent license
+you grant is automatically extended to all recipients of the covered
+work and works based on it.
+
+  A patent license is "discriminatory" if it does not include within
+the scope of its coverage, prohibits the exercise of, or is
+conditioned on the non-exercise of one or more of the rights that are
+specifically granted under this License.  You may not convey a covered
+work if you are a party to an arrangement with a third party that is
+in the business of distributing software, under which you make payment
+to the third party based on the extent of your activity of conveying
+the work, and under which the third party grants, to any of the
+parties who would receive the covered work from you, a discriminatory
+patent license (a) in connection with copies of the covered work
+conveyed by you (or copies made from those copies), or (b) primarily
+for and in connection with specific products or compilations that
+contain the covered work, unless you entered into that arrangement,
+or that patent license was granted, prior to 28 March 2007.
+
+  Nothing in this License shall be construed as excluding or limiting
+any implied license or other defenses to infringement that may
+otherwise be available to you under applicable patent law.
+
+  12. No Surrender of Others' Freedom.
+
+  If conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License.  If you cannot convey a
+covered work so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you may
+not convey it at all.  For example, if you agree to terms that obligate you
+to collect a royalty for further conveying from those to whom you convey
+the Program, the only way you could satisfy both those terms and this
+License would be to refrain entirely from conveying the Program.
+
+  13. Use with the GNU Affero General Public License.
+
+  Notwithstanding any other provision of this License, you have
+permission to link or combine any covered work with a work licensed
+under version 3 of the GNU Affero General Public License into a single
+combined work, and to convey the resulting work.  The terms of this
+License will continue to apply to the part which is the covered work,
+but the special requirements of the GNU Affero General Public License,
+section 13, concerning interaction through a network will apply to the
+combination as such.
+
+  14. Revised Versions of this License.
+
+  The Free Software Foundation may publish revised and/or new versions of
+the GNU General Public License from time to time.  Such new versions will
+be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.
+
+  Each version is given a distinguishing version number.  If the
+Program specifies that a certain numbered version of the GNU General
+Public License "or any later version" applies to it, you have the
+option of following the terms and conditions either of that numbered
+version or of any later version published by the Free Software
+Foundation.  If the Program does not specify a version number of the
+GNU General Public License, you may choose any version ever published
+by the Free Software Foundation.
+
+  If the Program specifies that a proxy can decide which future
+versions of the GNU General Public License can be used, that proxy's
+public statement of acceptance of a version permanently authorizes you
+to choose that version for the Program.
+
+  Later license versions may give you additional or different
+permissions.  However, no additional obligations are imposed on any
+author or copyright holder as a result of your choosing to follow a
+later version.
+
+  15. Disclaimer of Warranty.
+
+  THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
+APPLICABLE LAW.  EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
+HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY
+OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
+THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
+PURPOSE.  THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM
+IS WITH YOU.  SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
+ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
+
+  16. Limitation of Liability.
+
+  IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
+THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
+GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE
+USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF
+DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
+PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),
+EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF
+SUCH DAMAGES.
+
+  17. Interpretation of Sections 15 and 16.
+
+  If the disclaimer of warranty and limitation of liability provided
+above cannot be given local legal effect according to their terms,
+reviewing courts shall apply local law that most closely approximates
+an absolute waiver of all civil liability in connection with the
+Program, unless a warranty or assumption of liability accompanies a
+copy of the Program in return for a fee.
+
+                     END OF TERMS AND CONDITIONS

+                   GNU LESSER GENERAL PUBLIC LICENSE
+                       Version 3, 29 June 2007
+
+ Copyright (C) 2007 Free Software Foundation, Inc. <https://fsf.org/>
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+
+  This version of the GNU Lesser General Public License incorporates
+the terms and conditions of version 3 of the GNU General Public
+License, supplemented by the additional permissions listed below.
+
+  0. Additional Definitions.
+
+  As used herein, "this License" refers to version 3 of the GNU Lesser
+General Public License, and the "GNU GPL" refers to version 3 of the GNU
+General Public License.
+
+  "The Library" refers to a covered work governed by this License,
+other than an Application or a Combined Work as defined below.
+
+  An "Application" is any work that makes use of an interface provided
+by the Library, but which is not otherwise based on the Library.
+Defining a subclass of a class defined by the Library is deemed a mode
+of using an interface provided by the Library.
+
+  A "Combined Work" is a work produced by combining or linking an
+Application with the Library.  The particular version of the Library
+with which the Combined Work was made is also called the "Linked
+Version".
+
+  The "Minimal Corresponding Source" for a Combined Work means the
+Corresponding Source for the Combined Work, excluding any source code
+for portions of the Combined Work that, considered in isolation, are
+based on the Application, and not on the Linked Version.
+
+  The "Corresponding Application Code" for a Combined Work means the
+object code and/or source code for the Application, including any data
+and utility programs needed for reproducing the Combined Work from the
+Application, but excluding the System Libraries of the Combined Work.
+
+  1. Exception to Section 3 of the GNU GPL.
+
+  You may convey a covered work under sections 3 and 4 of this License
+without being bound by section 3 of the GNU GPL.
+
+  2. Conveying Modified Versions.
+
+  If you modify a copy of the Library, and, in your modifications, a
+facility refers to a function or data to be supplied by an Application
+that uses the facility (other than as an argument passed when the
+facility is invoked), then you may convey a copy of the modified
+version:
+
+   a) under this License, provided that you make a good faith effort to
+   ensure that, in the event an Application does not supply the
+   function or data, the facility still operates, and performs
+   whatever part of its purpose remains meaningful, or
+
+   b) under the GNU GPL, with none of the additional permissions of
+   this License applicable to that copy.
+
+  3. Object Code Incorporating Material from Library Header Files.
+
+  The object code form of an Application may incorporate material from
+a header file that is part of the Library.  You may convey such object
+code under terms of your choice, provided that, if the incorporated
+material is not limited to numerical parameters, data structure
+layouts and accessors, or small macros, inline functions and templates
+(ten or fewer lines in length), you do both of the following:
+
+   a) Give prominent notice with each copy of the object code that the
+   Library is used in it and that the Library and its use are
+   covered by this License.
+
+   b) Accompany the object code with a copy of the GNU GPL and this license
+   document.
+
+  4. Combined Works.
+
+  You may convey a Combined Work under terms of your choice that,
+taken together, effectively do not restrict modification of the
+portions of the Library contained in the Combined Work and reverse
+engineering for debugging such modifications, if you also do each of
+the following:
+
+   a) Give prominent notice with each copy of the Combined Work that
+   the Library is used in it and that the Library and its use are
+   covered by this License.
+
+   b) Accompany the Combined Work with a copy of the GNU GPL and this license
+   document.
+
+   c) For a Combined Work that displays copyright notices during
+   execution, include the copyright notice for the Library among
+   these notices, as well as a reference directing the user to the
+   copies of the GNU GPL and this license document.
+
+   d) Do one of the following:
+
+       0) Convey the Minimal Corresponding Source under the terms of this
+       License, and the Corresponding Application Code in a form
+       suitable for, and under terms that permit, the user to
+       recombine or relink the Application with a modified version of
+       the Linked Version to produce a modified Combined Work, in the
+       manner specified by section 6 of the GNU GPL for conveying
+       Corresponding Source.
+
+       1) Use a suitable shared library mechanism for linking with the
+       Library.  A suitable mechanism is one that (a) uses at run time
+       a copy of the Library already present on the user's computer
+       system, and (b) will operate properly with a modified version
+       of the Library that is interface-compatible with the Linked
+       Version.
+
+   e) Provide Installation Information, but only if you would otherwise
+   be required to provide such information under section 6 of the
+   GNU GPL, and only to the extent that such information is
+   necessary to install and execute a modified version of the
+   Combined Work produced by recombining or relinking the
+   Application with a modified version of the Linked Version. (If
+   you use option 4d0, the Installation Information must accompany
+   the Minimal Corresponding Source and Corresponding Application
+   Code. If you use option 4d1, you must provide the Installation
+   Information in the manner specified by section 6 of the GNU GPL
+   for conveying Corresponding Source.)
+
+  5. Combined Libraries.
+
+  You may place library facilities that are a work based on the
+Library side by side in a single library together with other library
+facilities that are not Applications and are not covered by this
+License, and convey such a combined library under terms of your
+choice, if you do both of the following:
+
+   a) Accompany the combined library with a copy of the same work based
+   on the Library, uncombined with any other library facilities,
+   conveyed under the terms of this License.
+
+   b) Give prominent notice with the combined library that part of it
+   is a work based on the Library, and explaining where to find the
+   accompanying uncombined form of the same work.
+
+  6. Revised Versions of the GNU Lesser General Public License.
+
+  The Free Software Foundation may publish revised and/or new versions
+of the GNU Lesser General Public License from time to time. Such new
+versions will be similar in spirit to the present version, but may
+differ in detail to address new problems or concerns.
+
+  Each version is given a distinguishing version number. If the
+Library as you received it specifies that a certain numbered version
+of the GNU Lesser General Public License "or any later version"
+applies to it, you have the option of following the terms and
+conditions either of that published version or of any later version
+published by the Free Software Foundation. If the Library as you
+received it does not specify a version number of the GNU Lesser
+General Public License, you may choose any version of the GNU Lesser
+General Public License ever published by the Free Software Foundation.
+
+  If the Library as you received it specifies that a proxy can decide
+whether future versions of the GNU Lesser General Public License shall
+apply, that proxy's public statement of acceptance of any version is
+permanent authorization for you to choose that version for the
+Library.

+                    GNU GENERAL PUBLIC LICENSE
+                       Version 3, 29 June 2007
+
+ Copyright (C) 2007 Free Software Foundation, Inc. <https://fsf.org/>
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+                            Preamble
+
+  The GNU General Public License is a free, copyleft license for
+software and other kinds of works.
+
+  The licenses for most software and other practical works are designed
+to take away your freedom to share and change the works.  By contrast,
+the GNU General Public License is intended to guarantee your freedom to
+share and change all versions of a program--to make sure it remains free
+software for all its users.  We, the Free Software Foundation, use the
+GNU General Public License for most of our software; it applies also to
+any other work released this way by its authors.  You can apply it to
+your programs, too.
+
+  When we speak of free software, we are referring to freedom, not
+price.  Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+them if you wish), that you receive source code or can get it if you
+want it, that you can change the software or use pieces of it in new
+free programs, and that you know you can do these things.
+
+  To protect your rights, we need to prevent others from denying you
+these rights or asking you to surrender the rights.  Therefore, you have
+certain responsibilities if you distribute copies of the software, or if
+you modify it: responsibilities to respect the freedom of others.
+
+  For example, if you distribute copies of such a program, whether
+gratis or for a fee, you must pass on to the recipients the same
+freedoms that you received.  You must make sure that they, too, receive
+or can get the source code.  And you must show them these terms so they
+know their rights.
+
+  Developers that use the GNU GPL protect your rights with two steps:
+(1) assert copyright on the software, and (2) offer you this License
+giving you legal permission to copy, distribute and/or modify it.
+
+  For the developers' and authors' protection, the GPL clearly explains
+that there is no warranty for this free software.  For both users' and
+authors' sake, the GPL requires that modified versions be marked as
+changed, so that their problems will not be attributed erroneously to
+authors of previous versions.
+
+  Some devices are designed to deny users access to install or run
+modified versions of the software inside them, although the manufacturer
+can do so.  This is fundamentally incompatible with the aim of
+protecting users' freedom to change the software.  The systematic
+pattern of such abuse occurs in the area of products for individuals to
+use, which is precisely where it is most unacceptable.  Therefore, we
+have designed this version of the GPL to prohibit the practice for those
+products.  If such problems arise substantially in other domains, we
+stand ready to extend this provision to those domains in future versions
+of the GPL, as needed to protect the freedom of users.
+
+  Finally, every program is threatened constantly by software patents.
+States should not allow patents to restrict development and use of
+software on general-purpose computers, but in those that do, we wish to
+avoid the special danger that patents applied to a free program could
+make it effectively proprietary.  To prevent this, the GPL assures that
+patents cannot be used to render the program non-free.
+
+  The precise terms and conditions for copying, distribution and
+modification follow.
+
+                       TERMS AND CONDITIONS
+
+  0. Definitions.
+
+  "This License" refers to version 3 of the GNU General Public License.
+
+  "Copyright" also means copyright-like laws that apply to other kinds of
+works, such as semiconductor masks.
+
+  "The Program" refers to any copyrightable work licensed under this
+License.  Each licensee is addressed as "you".  "Licensees" and
+"recipients" may be individuals or organizations.
+
+  To "modify" a work means to copy from or adapt all or part of the work
+in a fashion requiring copyright permission, other than the making of an
+exact copy.  The resulting work is called a "modified version" of the
+earlier work or a work "based on" the earlier work.
+
+  A "covered work" means either the unmodified Program or a work based
+on the Program.
+
+  To "propagate" a work means to do anything with it that, without
+permission, would make you directly or secondarily liable for
+infringement under applicable copyright law, except executing it on a
+computer or modifying a private copy.  Propagation includes copying,
+distribution (with or without modification), making available to the
+public, and in some countries other activities as well.
+
+  To "convey" a work means any kind of propagation that enables other
+parties to make or receive copies.  Mere interaction with a user through
+a computer network, with no transfer of a copy, is not conveying.
+
+  An interactive user interface displays "Appropriate Legal Notices"
+to the extent that it includes a convenient and prominently visible
+feature that (1) displays an appropriate copyright notice, and (2)
+tells the user that there is no warranty for the work (except to the
+extent that warranties are provided), that licensees may convey the
+work under this License, and how to view a copy of this License.  If
+the interface presents a list of user commands or options, such as a
+menu, a prominent item in the list meets this criterion.
+
+  1. Source Code.
+
+  The "source code" for a work means the preferred form of the work
+for making modifications to it.  "Object code" means any non-source
+form of a work.
+
+  A "Standard Interface" means an interface that either is an official
+standard defined by a recognized standards body, or, in the case of
+interfaces specified for a particular programming language, one that
+is widely used among developers working in that language.
+
+  The "System Libraries" of an executable work include anything, other
+than the work as a whole, that (a) is included in the normal form of
+packaging a Major Component, but which is not part of that Major
+Component, and (b) serves only to enable use of the work with that
+Major Component, or to implement a Standard Interface for which an
+implementation is available to the public in source code form.  A
+"Major Component", in this context, means a major essential component
+(kernel, window system, and so on) of the specific operating system
+(if any) on which the executable work runs, or a compiler used to
+produce the work, or an object code interpreter used to run it.
+
+  The "Corresponding Source" for a work in object code form means all
+the source code needed to generate, install, and (for an executable
+work) run the object code and to modify the work, including scripts to
+control those activities.  However, it does not include the work's
+System Libraries, or general-purpose tools or generally available free
+programs which are used unmodified in performing those activities but
+which are not part of the work.  For example, Corresponding Source
+includes interface definition files associated with source files for
+the work, and the source code for shared libraries and dynamically
+linked subprograms that the work is specifically designed to require,
+such as by intimate data communication or control flow between those
+subprograms and other parts of the work.
+
+  The Corresponding Source need not include anything that users
+can regenerate automatically from other parts of the Corresponding
+Source.
+
+  The Corresponding Source for a work in source code form is that
+same work.
+
+  2. Basic Permissions.
+
+  All rights granted under this License are granted for the term of
+copyright on the Program, and are irrevocable provided the stated
+conditions are met.  This License explicitly affirms your unlimited
+permission to run the unmodified Program.  The output from running a
+covered work is covered by this License only if the output, given its
+content, constitutes a covered work.  This License acknowledges your
+rights of fair use or other equivalent, as provided by copyright law.
+
+  You may make, run and propagate covered works that you do not
+convey, without conditions so long as your license otherwise remains
+in force.  You may convey covered works to others for the sole purpose
+of having them make modifications exclusively for you, or provide you
+with facilities for running those works, provided that you comply with
+the terms of this License in conveying all material for which you do
+not control copyright.  Those thus making or running the covered works
+for you must do so exclusively on your behalf, under your direction
+and control, on terms that prohibit them from making any copies of
+your copyrighted material outside their relationship with you.
+
+  Conveying under any other circumstances is permitted solely under
+the conditions stated below.  Sublicensing is not allowed; section 10
+makes it unnecessary.
+
+  3. Protecting Users' Legal Rights From Anti-Circumvention Law.
+
+  No covered work shall be deemed part of an effective technological
+measure under any applicable law fulfilling obligations under article
+11 of the WIPO copyright treaty adopted on 20 December 1996, or
+similar laws prohibiting or restricting circumvention of such
+measures.
+
+  When you convey a covered work, you waive any legal power to forbid
+circumvention of technological measures to the extent such circumvention
+is effected by exercising rights under this License with respect to
+the covered work, and you disclaim any intention to limit operation or
+modification of the work as a means of enforcing, against the work's
+users, your or third parties' legal rights to forbid circumvention of
+technological measures.
+
+  4. Conveying Verbatim Copies.
+
+  You may convey verbatim copies of the Program's source code as you
+receive it, in any medium, provided that you conspicuously and
+appropriately publish on each copy an appropriate copyright notice;
+keep intact all notices stating that this License and any
+non-permissive terms added in accord with section 7 apply to the code;
+keep intact all notices of the absence of any warranty; and give all
+recipients a copy of this License along with the Program.
+
+  You may charge any price or no price for each copy that you convey,
+and you may offer support or warranty protection for a fee.
+
+  5. Conveying Modified Source Versions.
+
+  You may convey a work based on the Program, or the modifications to
+produce it from the Program, in the form of source code under the
+terms of section 4, provided that you also meet all of these conditions:
+
+    a) The work must carry prominent notices stating that you modified
+    it, and giving a relevant date.
+
+    b) The work must carry prominent notices stating that it is
+    released under this License and any conditions added under section
+    7.  This requirement modifies the requirement in section 4 to
+    "keep intact all notices".
+
+    c) You must license the entire work, as a whole, under this
+    License to anyone who comes into possession of a copy.  This
+    License will therefore apply, along with any applicable section 7
+    additional terms, to the whole of the work, and all its parts,
+    regardless of how they are packaged.  This License gives no
+    permission to license the work in any other way, but it does not
+    invalidate such permission if you have separately received it.
+
+    d) If the work has interactive user interfaces, each must display
+    Appropriate Legal Notices; however, if the Program has interactive
+    interfaces that do not display Appropriate Legal Notices, your
+    work need not make them do so.
+
+  A compilation of a covered work with other separate and independent
+works, which are not by their nature extensions of the covered work,
+and which are not combined with it such as to form a larger program,
+in or on a volume of a storage or distribution medium, is called an
+"aggregate" if the compilation and its resulting copyright are not
+used to limit the access or legal rights of the compilation's users
+beyond what the individual works permit.  Inclusion of a covered work
+in an aggregate does not cause this License to apply to the other
+parts of the aggregate.
+
+  6. Conveying Non-Source Forms.
+
+  You may convey a covered work in object code form under the terms
+of sections 4 and 5, provided that you also convey the
+machine-readable Corresponding Source under the terms of this License,
+in one of these ways:
+
+    a) Convey the object code in, or embodied in, a physical product
+    (including a physical distribution medium), accompanied by the
+    Corresponding Source fixed on a durable physical medium
+    customarily used for software interchange.
+
+    b) Convey the object code in, or embodied in, a physical product
+    (including a physical distribution medium), accompanied by a
+    written offer, valid for at least three years and valid for as
+    long as you offer spare parts or customer support for that product
+    model, to give anyone who possesses the object code either (1) a
+    copy of the Corresponding Source for all the software in the
+    product that is covered by this License, on a durable physical
+    medium customarily used for software interchange, for a price no
+    more than your reasonable cost of physically performing this
+    conveying of source, or (2) access to copy the
+    Corresponding Source from a network server at no charge.
+
+    c) Convey individual copies of the object code with a copy of the
+    written offer to provide the Corresponding Source.  This
+    alternative is allowed only occasionally and noncommercially, and
+    only if you received the object code with such an offer, in accord
+    with subsection 6b.
+
+    d) Convey the object code by offering access from a designated
+    place (gratis or for a charge), and offer equivalent access to the
+    Corresponding Source in the same way through the same place at no
+    further charge.  You need not require recipients to copy the
+    Corresponding Source along with the object code.  If the place to
+    copy the object code is a network server, the Corresponding Source
+    may be on a different server (operated by you or a third party)
+    that supports equivalent copying facilities, provided you maintain
+    clear directions next to the object code saying where to find the
+    Corresponding Source.  Regardless of what server hosts the
+    Corresponding Source, you remain obligated to ensure that it is
+    available for as long as needed to satisfy these requirements.
+
+    e) Convey the object code using peer-to-peer transmission, provided
+    you inform other peers where the object code and Corresponding
+    Source of the work are being offered to the general public at no
+    charge under subsection 6d.
+
+  A separable portion of the object code, whose source code is excluded
+from the Corresponding Source as a System Library, need not be
+included in conveying the object code work.
+
+  A "User Product" is either (1) a "consumer product", which means any
+tangible personal property which is normally used for personal, family,
+or household purposes, or (2) anything designed or sold for incorporation
+into a dwelling.  In determining whether a product is a consumer product,
+doubtful cases shall be resolved in favor of coverage.  For a particular
+product received by a particular user, "normally used" refers to a
+typical or common use of that class of product, regardless of the status
+of the particular user or of the way in which the particular user
+actually uses, or expects or is expected to use, the product.  A product
+is a consumer product regardless of whether the product has substantial
+commercial, industrial or non-consumer uses, unless such uses represent
+the only significant mode of use of the product.
+
+  "Installation Information" for a User Product means any methods,
+procedures, authorization keys, or other information required to install
+and execute modified versions of a covered work in that User Product from
+a modified version of its Corresponding Source.  The information must
+suffice to ensure that the continued functioning of the modified object
+code is in no case prevented or interfered with solely because
+modification has been made.
+
+  If you convey an object code work under this section in, or with, or
+specifically for use in, a User Product, and the conveying occurs as
+part of a transaction in which the right of possession and use of the
+User Product is transferred to the recipient in perpetuity or for a
+fixed term (regardless of how the transaction is characterized), the
+Corresponding Source conveyed under this section must be accompanied
+by the Installation Information.  But this requirement does not apply
+if neither you nor any third party retains the ability to install
+modified object code on the User Product (for example, the work has
+been installed in ROM).
+
+  The requirement to provide Installation Information does not include a
+requirement to continue to provide support service, warranty, or updates
+for a work that has been modified or installed by the recipient, or for
+the User Product in which it has been modified or installed.  Access to a
+network may be denied when the modification itself materially and
+adversely affects the operation of the network or violates the rules and
+protocols for communication across the network.
+
+  Corresponding Source conveyed, and Installation Information provided,
+in accord with this section must be in a format that is publicly
+documented (and with an implementation available to the public in
+source code form), and must require no special password or key for
+unpacking, reading or copying.
+
+  7. Additional Terms.
+
+  "Additional permissions" are terms that supplement the terms of this
+License by making exceptions from one or more of its conditions.
+Additional permissions that are applicable to the entire Program shall
+be treated as though they were included in this License, to the extent
+that they are valid under applicable law.  If additional permissions
+apply only to part of the Program, that part may be used separately
+under those permissions, but the entire Program remains governed by
+this License without regard to the additional permissions.
+
+  When you convey a copy of a covered work, you may at your option
+remove any additional permissions from that copy, or from any part of
+it.  (Additional permissions may be written to require their own
+removal in certain cases when you modify the work.)  You may place
+additional permissions on material, added by you to a covered work,
+for which you have or can give appropriate copyright permission.
+
+  Notwithstanding any other provision of this License, for material you
+add to a covered work, you may (if authorized by the copyright holders of
+that material) supplement the terms of this License with terms:
+
+    a) Disclaiming warranty or limiting liability differently from the
+    terms of sections 15 and 16 of this License; or
+
+    b) Requiring preservation of specified reasonable legal notices or
+    author attributions in that material or in the Appropriate Legal
+    Notices displayed by works containing it; or
+
+    c) Prohibiting misrepresentation of the origin of that material, or
+    requiring that modified versions of such material be marked in
+    reasonable ways as different from the original version; or
+
+    d) Limiting the use for publicity purposes of names of licensors or
+    authors of the material; or
+
+    e) Declining to grant rights under trademark law for use of some
+    trade names, trademarks, or service marks; or
+
+    f) Requiring indemnification of licensors and authors of that
+    material by anyone who conveys the material (or modified versions of
+    it) with contractual assumptions of liability to the recipient, for
+    any liability that these contractual assumptions directly impose on
+    those licensors and authors.
+
+  All other non-permissive additional terms are considered "further
+restrictions" within the meaning of section 10.  If the Program as you
+received it, or any part of it, contains a notice stating that it is
+governed by this License along with a term that is a further
+restriction, you may remove that term.  If a license document contains
+a further restriction but permits relicensing or conveying under this
+License, you may add to a covered work material governed by the terms
+of that license document, provided that the further restriction does
+not survive such relicensing or conveying.
+
+  If you add terms to a covered work in accord with this section, you
+must place, in the relevant source files, a statement of the
+additional terms that apply to those files, or a notice indicating
+where to find the applicable terms.
+
+  Additional terms, permissive or non-permissive, may be stated in the
+form of a separately written license, or stated as exceptions;
+the above requirements apply either way.
+
+  8. Termination.
+
+  You may not propagate or modify a covered work except as expressly
+provided under this License.  Any attempt otherwise to propagate or
+modify it is void, and will automatically terminate your rights under
+this License (including any patent licenses granted under the third
+paragraph of section 11).
+
+  However, if you cease all violation of this License, then your
+license from a particular copyright holder is reinstated (a)
+provisionally, unless and until the copyright holder explicitly and
+finally terminates your license, and (b) permanently, if the copyright
+holder fails to notify you of the violation by some reasonable means
+prior to 60 days after the cessation.
+
+  Moreover, your license from a particular copyright holder is
+reinstated permanently if the copyright holder notifies you of the
+violation by some reasonable means, this is the first time you have
+received notice of violation of this License (for any work) from that
+copyright holder, and you cure the violation prior to 30 days after
+your receipt of the notice.
+
+  Termination of your rights under this section does not terminate the
+licenses of parties who have received copies or rights from you under
+this License.  If your rights have been terminated and not permanently
+reinstated, you do not qualify to receive new licenses for the same
+material under section 10.
+
+  9. Acceptance Not Required for Having Copies.
+
+  You are not required to accept this License in order to receive or
+run a copy of the Program.  Ancillary propagation of a covered work
+occurring solely as a consequence of using peer-to-peer transmission
+to receive a copy likewise does not require acceptance.  However,
+nothing other than this License grants you permission to propagate or
+modify any covered work.  These actions infringe copyright if you do
+not accept this License.  Therefore, by modifying or propagating a
+covered work, you indicate your acceptance of this License to do so.
+
+  10. Automatic Licensing of Downstream Recipients.
+
+  Each time you convey a covered work, the recipient automatically
+receives a license from the original licensors, to run, modify and
+propagate that work, subject to this License.  You are not responsible
+for enforcing compliance by third parties with this License.
+
+  An "entity transaction" is a transaction transferring control of an
+organization, or substantially all assets of one, or subdividing an
+organization, or merging organizations.  If propagation of a covered
+work results from an entity transaction, each party to that
+transaction who receives a copy of the work also receives whatever
+licenses to the work the party's predecessor in interest had or could
+give under the previous paragraph, plus a right to possession of the
+Corresponding Source of the work from the predecessor in interest, if
+the predecessor has it or can get it with reasonable efforts.
+
+  You may not impose any further restrictions on the exercise of the
+rights granted or affirmed under this License.  For example, you may
+not impose a license fee, royalty, or other charge for exercise of
+rights granted under this License, and you may not initiate litigation
+(including a cross-claim or counterclaim in a lawsuit) alleging that
+any patent claim is infringed by making, using, selling, offering for
+sale, or importing the Program or any portion of it.
+
+  11. Patents.
+
+  A "contributor" is a copyright holder who authorizes use under this
+License of the Program or a work on which the Program is based.  The
+work thus licensed is called the contributor's "contributor version".
+
+  A contributor's "essential patent claims" are all patent claims
+owned or controlled by the contributor, whether already acquired or
+hereafter acquired, that would be infringed by some manner, permitted
+by this License, of making, using, or selling its contributor version,
+but do not include claims that would be infringed only as a
+consequence of further modification of the contributor version.  For
+purposes of this definition, "control" includes the right to grant
+patent sublicenses in a manner consistent with the requirements of
+this License.
+
+  Each contributor grants you a non-exclusive, worldwide, royalty-free
+patent license under the contributor's essential patent claims, to
+make, use, sell, offer for sale, import and otherwise run, modify and
+propagate the contents of its contributor version.
+
+  In the following three paragraphs, a "patent license" is any express
+agreement or commitment, however denominated, not to enforce a patent
+(such as an express permission to practice a patent or covenant not to
+sue for patent infringement).  To "grant" such a patent license to a
+party means to make such an agreement or commitment not to enforce a
+patent against the party.
+
+  If you convey a covered work, knowingly relying on a patent license,
+and the Corresponding Source of the work is not available for anyone
+to copy, free of charge and under the terms of this License, through a
+publicly available network server or other readily accessible means,
+then you must either (1) cause the Corresponding Source to be so
+available, or (2) arrange to deprive yourself of the benefit of the
+patent license for this particular work, or (3) arrange, in a manner
+consistent with the requirements of this License, to extend the patent
+license to downstream recipients.  "Knowingly relying" means you have
+actual knowledge that, but for the patent license, your conveying the
+covered work in a country, or your recipient's use of the covered work
+in a country, would infringe one or more identifiable patents in that
+country that you have reason to believe are valid.
+
+  If, pursuant to or in connection with a single transaction or
+arrangement, you convey, or propagate by procuring conveyance of, a
+covered work, and grant a patent license to some of the parties
+receiving the covered work authorizing them to use, propagate, modify
+or convey a specific copy of the covered work, then the patent license
+you grant is automatically extended to all recipients of the covered
+work and works based on it.
+
+  A patent license is "discriminatory" if it does not include within
+the scope of its coverage, prohibits the exercise of, or is
+conditioned on the non-exercise of one or more of the rights that are
+specifically granted under this License.  You may not convey a covered
+work if you are a party to an arrangement with a third party that is
+in the business of distributing software, under which you make payment
+to the third party based on the extent of your activity of conveying
+the work, and under which the third party grants, to any of the
+parties who would receive the covered work from you, a discriminatory
+patent license (a) in connection with copies of the covered work
+conveyed by you (or copies made from those copies), or (b) primarily
+for and in connection with specific products or compilations that
+contain the covered work, unless you entered into that arrangement,
+or that patent license was granted, prior to 28 March 2007.
+
+  Nothing in this License shall be construed as excluding or limiting
+any implied license or other defenses to infringement that may
+otherwise be available to you under applicable patent law.
+
+  12. No Surrender of Others' Freedom.
+
+  If conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License.  If you cannot convey a
+covered work so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you may
+not convey it at all.  For example, if you agree to terms that obligate you
+to collect a royalty for further conveying from those to whom you convey
+the Program, the only way you could satisfy both those terms and this
+License would be to refrain entirely from conveying the Program.
+
+  13. Use with the GNU Affero General Public License.
+
+  Notwithstanding any other provision of this License, you have
+permission to link or combine any covered work with a work licensed
+under version 3 of the GNU Affero General Public License into a single
+combined work, and to convey the resulting work.  The terms of this
+License will continue to apply to the part which is the covered work,
+but the special requirements of the GNU Affero General Public License,
+section 13, concerning interaction through a network will apply to the
+combination as such.
+
+  14. Revised Versions of this License.
+
+  The Free Software Foundation may publish revised and/or new versions of
+the GNU General Public License from time to time.  Such new versions will
+be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.
+
+  Each version is given a distinguishing version number.  If the
+Program specifies that a certain numbered version of the GNU General
+Public License "or any later version" applies to it, you have the
+option of following the terms and conditions either of that numbered
+version or of any later version published by the Free Software
+Foundation.  If the Program does not specify a version number of the
+GNU General Public License, you may choose any version ever published
+by the Free Software Foundation.
+
+  If the Program specifies that a proxy can decide which future
+versions of the GNU General Public License can be used, that proxy's
+public statement of acceptance of a version permanently authorizes you
+to choose that version for the Program.
+
+  Later license versions may give you additional or different
+permissions.  However, no additional obligations are imposed on any
+author or copyright holder as a result of your choosing to follow a
+later version.
+
+  15. Disclaimer of Warranty.
+
+  THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
+APPLICABLE LAW.  EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
+HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY
+OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
+THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
+PURPOSE.  THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM
+IS WITH YOU.  SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
+ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
+
+  16. Limitation of Liability.
+
+  IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
+THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
+GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE
+USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF
+DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
+PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),
+EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF
+SUCH DAMAGES.
+
+  17. Interpretation of Sections 15 and 16.
+
+  If the disclaimer of warranty and limitation of liability provided
+above cannot be given local legal effect according to their terms,
+reviewing courts shall apply local law that most closely approximates
+an absolute waiver of all civil liability in connection with the
+Program, unless a warranty or assumption of liability accompanies a
+copy of the Program in return for a fee.
+
+                     END OF TERMS AND CONDITIONS

+                   GNU LESSER GENERAL PUBLIC LICENSE
+                       Version 3, 29 June 2007
+
+ Copyright (C) 2007 Free Software Foundation, Inc. <https://fsf.org/>
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+
+  This version of the GNU Lesser General Public License incorporates
+the terms and conditions of version 3 of the GNU General Public
+License, supplemented by the additional permissions listed below.
+
+  0. Additional Definitions.
+
+  As used herein, "this License" refers to version 3 of the GNU Lesser
+General Public License, and the "GNU GPL" refers to version 3 of the GNU
+General Public License.
+
+  "The Library" refers to a covered work governed by this License,
+other than an Application or a Combined Work as defined below.
+
+  An "Application" is any work that makes use of an interface provided
+by the Library, but which is not otherwise based on the Library.
+Defining a subclass of a class defined by the Library is deemed a mode
+of using an interface provided by the Library.
+
+  A "Combined Work" is a work produced by combining or linking an
+Application with the Library.  The particular version of the Library
+with which the Combined Work was made is also called the "Linked
+Version".
+
+  The "Minimal Corresponding Source" for a Combined Work means the
+Corresponding Source for the Combined Work, excluding any source code
+for portions of the Combined Work that, considered in isolation, are
+based on the Application, and not on the Linked Version.
+
+  The "Corresponding Application Code" for a Combined Work means the
+object code and/or source code for the Application, including any data
+and utility programs needed for reproducing the Combined Work from the
+Application, but excluding the System Libraries of the Combined Work.
+
+  1. Exception to Section 3 of the GNU GPL.
+
+  You may convey a covered work under sections 3 and 4 of this License
+without being bound by section 3 of the GNU GPL.
+
+  2. Conveying Modified Versions.
+
+  If you modify a copy of the Library, and, in your modifications, a
+facility refers to a function or data to be supplied by an Application
+that uses the facility (other than as an argument passed when the
+facility is invoked), then you may convey a copy of the modified
+version:
+
+   a) under this License, provided that you make a good faith effort to
+   ensure that, in the event an Application does not supply the
+   function or data, the facility still operates, and performs
+   whatever part of its purpose remains meaningful, or
+
+   b) under the GNU GPL, with none of the additional permissions of
+   this License applicable to that copy.
+
+  3. Object Code Incorporating Material from Library Header Files.
+
+  The object code form of an Application may incorporate material from
+a header file that is part of the Library.  You may convey such object
+code under terms of your choice, provided that, if the incorporated
+material is not limited to numerical parameters, data structure
+layouts and accessors, or small macros, inline functions and templates
+(ten or fewer lines in length), you do both of the following:
+
+   a) Give prominent notice with each copy of the object code that the
+   Library is used in it and that the Library and its use are
+   covered by this License.
+
+   b) Accompany the object code with a copy of the GNU GPL and this license
+   document.
+
+  4. Combined Works.
+
+  You may convey a Combined Work under terms of your choice that,
+taken together, effectively do not restrict modification of the
+portions of the Library contained in the Combined Work and reverse
+engineering for debugging such modifications, if you also do each of
+the following:
+
+   a) Give prominent notice with each copy of the Combined Work that
+   the Library is used in it and that the Library and its use are
+   covered by this License.
+
+   b) Accompany the Combined Work with a copy of the GNU GPL and this license
+   document.
+
+   c) For a Combined Work that displays copyright notices during
+   execution, include the copyright notice for the Library among
+   these notices, as well as a reference directing the user to the
+   copies of the GNU GPL and this license document.
+
+   d) Do one of the following:
+
+       0) Convey the Minimal Corresponding Source under the terms of this
+       License, and the Corresponding Application Code in a form
+       suitable for, and under terms that permit, the user to
+       recombine or relink the Application with a modified version of
+       the Linked Version to produce a modified Combined Work, in the
+       manner specified by section 6 of the GNU GPL for conveying
+       Corresponding Source.
+
+       1) Use a suitable shared library mechanism for linking with the
+       Library.  A suitable mechanism is one that (a) uses at run time
+       a copy of the Library already present on the user's computer
+       system, and (b) will operate properly with a modified version
+       of the Library that is interface-compatible with the Linked
+       Version.
+
+   e) Provide Installation Information, but only if you would otherwise
+   be required to provide such information under section 6 of the
+   GNU GPL, and only to the extent that such information is
+   necessary to install and execute a modified version of the
+   Combined Work produced by recombining or relinking the

+
+  You may place library facilities that are a work based on the
+Library side by side in a single library together with other library
+facilities that are not Applications and are not covered by this
+License, and convey such a combined library under terms of your
+choice, if you do both of the following:
+
+   a) Accompany the combined library with a copy of the same work based
+   on the Library, uncombined with any other library facilities,
+   conveyed under the terms of this License.
+
+   b) Give prominent notice with the combined library that part of it
+   is a work based on the Library, and explaining where to find the
+   accompanying uncombined form of the same work.

+  6. Revised Versions of the GNU Lesser General Public License.
+
+  The Free Software Foundation may publish revised and/or new versions
+of the GNU Lesser General Public License from time to time. Such new
+versions will be similar in spirit to the present version, but may
+differ in detail to address new problems or concerns.
+
+  Each version is given a distinguishing version number. If the
+Library as you received it specifies that a certain numbered version
+of the GNU Lesser General Public License "or any later version"
+applies to it, you have the option of following the terms and
+conditions either of that published version or of any later version
+published by the Free Software Foundation. If the Library as you
+received it does not specify a version number of the GNU Lesser
+General Public License, you may choose any version of the GNU Lesser
+General Public License ever published by the Free Software Foundation.
+
+  If the Library as you received it specifies that a proxy can decide
+whether future versions of the GNU Lesser General Public License shall
+apply, that proxy's public statement of acceptance of any version is
+permanent authorization for you to choose that version for the
+Library.

+# IfcFM
+
+IfcFM is a library that handles the extraction and analysis of IFC data for the
+purposes of facility management.
+
+It is currently a prototype and will supersede the IfcCOBie library. It is
+planned to support workflows related to the old COBie standard, as well as
+upcoming IFC Facility Management related MVDs.

Before publication, it may want to set the IfcChangeActionEnum to NOCHANGE to establish a baseline so that other application changes can be easily identified. Application B then receives this IFC dataset and adds a new object and sets IfcChangeActionEnum to ADDED with Application B defined as the OwningApplication. Application B then modifies an existing object and (re)defines the LastModifiedDate to the time of the modification, LastModifyingUser to the IfcPersonAndOrganization making the change, and sets the LastModifyingApplication to Application B. When Application A receives this modified dataset, it can determine which objects have been added and modified by Application B and either merge or reject these changes as necessary. Consequently, the intent is that an application only modifies the value of IfcChangeActionEnum when it does something to the object, with the further intent that a model server is responsible for clearing the IfcChangeActionEnum back to NOCHANGE when it is ready to be republished.

+/// IfcCompoundPlaneAngleMeasure is a compound measure of plane angle in degrees, minutes, seconds, and optionally millionth-seconds of arc.

It may be used for angular measurement by surveyors or for other angular measurements where precision is required. Another usage is exact or approximate global positioning against a geographic coordinate systems using longitude and latitude.
+/// 
+/// NOTE: While the unit of measurement of the type IfcPlaneAngleMeasure depends on unit assignment (radian or degree or other derived units; globally at the IfcPoject or locally at an IfcMeasureWithUnit), the units of IfcCompoundPlaneAngleMeasure are always degrees, minutes, seconds, and millionth-seconds irrespective of unit assignments.
+/// 
+/// HISTORY New type in IFC Release 1.5.1.
+/// 
+/// Type: LIST [3:4] OF INTEGER
+/// 
+/// Value restrictions
+/// 
+/// The first integer measure is the number of degrees and is generally not range-restricted.  However, when IfcCompoundPlaneAngleMeasure is used to express geographic coordinates, only latitudes of [-90, 90] and longitudes of [-180, 180] are used in practice.
+/// The second integer measure is the number of minutes and shall be in the range (-60, 60).
+/// The third integer measure is the number of seconds and shall be in the range (-60, 60).
+/// The optional fourth integer measure is the number of millionth-seconds and shall be in the range (-1 000 000, 1 000 000).
+/// 
+/// Signedness
+/// 
+/// All measure components have the same sign (positive or negative).  It is therefore trivial to convert between floating point representation (decimal degrees) and compound representation regardless whether the angle is greater or smaller than zero.  Example:
+/// 
+/// LOCAL
+///   a : IfcPlaneAngleMeasure := -50.975864;  (* decimal degrees, -50° 58' 33" 110400 *)
+///   b : IfcPlaneAngleMeasure;
+///   c : IfcCompoundPlaneAngleMeasure;
+///   s : IfcText;
+/// END_LOCAL;
+/// 
+/// (* convert from float to compound *)
+///   c[1] :=    a;                                           -- -50
+///   c[2] :=   (a - c[1]) * 60;                              -- -58
+///   c[3] :=  ((a - c[1]) * 60 - c[2]) * 60;                 -- -33
+///   c[4] := (((a - c[1]) * 60 - c[2]) * 60 - c[3]) * 1.e6;  -- -110400
+/// 
+/// (* convert from compound to float *)
+///   b := c[1] + c[2]/60. + c[3]/3600. + c[4]/3600.e6;       -- -50.975864
+/// 
+/// Use in string representations
+/// 
+/// When a compound plane angle measure is formatted for display or printout, the signs of the fractional components will usually be discarded because, to a human reader, the sign of the first component alone already indicates the sense of the angle:
+/// 
+/// (* convert from compound to human-readable string *)
+///   s := FORMAT(c[1], '+##')     + "000000B0"
+///      + FORMAT(ABS(c[2]), '##') + ''''
+///      + FORMAT(ABS(c[3]), '##') + '"'
+///      + FORMAT(ABS(c[4]), '##');  -- -50° 58' 33" 110400
+/// 
+/// Another often encountered display format of latitudes and longitudes is to omit the signs and print N, S, E, W indicators instead, for example, 50°58'33"S.  When stored as IfcCompoundPlaneAngleMeasure however, a compound plane angle measure is always signed, with same sign of all components.

+/// Definition from CSS1 (W3C Recommendation): The 'font-weight' property selects the weight of the font. The values '100' to '900' form an ordered sequence, where each number indicates a weight that is at least as dark as its predecessor. The keyword 'normal' is synonymous with '400', and 'bold' is synonymous with '700'. Keywords other than 'normal' and 'bold' have been shown to be often confused with font names and a numerical scale was therefore chosen for the 9-value list. Values are:
+/// 
+/// normal 
+///   bold 
+///   100 | 200 | 300 | 400 | 500 | 600 | 700 | 800 | 900
+/// 
+/// Fonts (the font data) typically have one or more properties whose values are names that are descriptive of the "weight" of a font. There is no accepted, universal meaning to these weight names. Their primary role is to distinguish faces of differing darkness within a single font family. Usage across font families is quite variant; for example a font that you might think of as being bold might be described as being Regular, Roman, Book, Medium, Semi- or DemiBold, Bold, or Black, depending on how black the "normal" face of the font is within the design. Because there is no standard usage of names, the weight property values in CSS1 are given on a numerical scale in which the value '400' (or 'normal') corresponds to the "normal" text face for that family. The weight name associated with that face will typically be Book, Regular, Roman, Normal or sometimes Medium.
+/// 
+/// The association of other weights within a family to the numerical weight values is intended only to preserve the ordering of darkness within that family. However, the following heuristics tell how the assignment is done in typical cases:
+/// 
+/// If the font family already uses a numerical scale with nine values (such as with OpenType), the font weights should be mapped directly. 
+///   If there is both a face labeled Medium and one labeled Book, Regular, Roman or Normal, then the Medium is normally assigned to the '500'. 
+///   The font labeled "Bold" will often correspond to the weight value '700'. 
+///   If there are fewer then 9 weights in the family, the default algorithm for filling the "holes" is as follows. If '500' is unassigned, it will be assigned the same font as '400'. If any of the values '600', '700', '800' or '900' remains unassigned, they are assigned to the same face as the next darker assigned keyword, if any, or the next lighter one otherwise. If any of '300', '200' or '100' remains unassigned, it is assigned to the next lighter assigned keyword, if any, or the next darker otherwise. 
+/// 
+/// The following two examples illustrate the process. Assume four weights in the "Example1" family, from lightest to darkest: Regular, Medium, Bold, Heavy. And assume six weights in the "Example2" family: Book, Medium, Bold, Heavy, Black, ExtraBlack. Note how in the second example it has been decided not to assign "Example2 ExtraBlack" to anything.

+///   Topic 2: If the relationship between any two coordinate
+///   reference systems is known, coordinates can be transformed
+///   or converted to another coordinate reference system.
+///   Coordinate operations are divided into two subtypes:
+/// 
+/// Coordinate conversion – mathematical
+///   operation on coordinates that does not include any change
+///   of datum. The best-known example of a coordinate
+///   conversion is a map projection. The parameters describing
+///   coordinate conversions are defined rather than
+///   empirically derived. Note that some conversions have no
+///   parameters.
+/// 
+/// Coordinate transformation – mathematical
+///   operation on coordinates that usually includes a change
+///   of datum. The parameters of a coordinate transformation
+///   are empirically derived from data containing the
+///   coordinates of a series of points in both coordinate
+///   reference systems. This computational process is usually
+///   ‘over-determined’, allowing derivation of
+///   error (or accuracy) estimates for the transformation.
+///   Also, the stochastic nature of the parameters may result
+///   in multiple (different) versions of the same coordinate
+///   transformation. Because of this several transformations
+///   may exist for a given pair of coordinate reference
+///   systems, differing in their transformation method,
+///   parameter values and accuracy characteristics.
+/// 
+/// The coordinate operation is an
+///   abstract supertype to handle any operation (transformation
+///   or conversion) between two coordinate reference systems. It
+///   is meant to provide expandability for future versions,
+///   since currently only the conversion of a local engineering
+///   coordinate system into a map coordinate reference system is
+///   dealt with by the subtype IfcMapConversion.
+/// 
+/// By convention, a coordinate operation is given between the
+///   SourceCRS being the more local, or child coordinate
+///   reference system, and the TargetCRS being the more
+///   remote or parent coordinate reference system, in
+///   thespecial case the coordinate operation between the local
+///   engineering coordinate system of the construction project
+///   and any map or other coordinate reference system.

+/// IfcProfileDef
+/// is the supertype of all definitions of standard and arbitrary profiles
+/// within IFC. It is used to define a standard set of commonly used
+/// section profiles by their parameters or by their explicit curve geometry.
+/// 
+/// Parameterized profiles are 2D primitives, which are used within the industry to describe cross
+///   sections by a description of its parameters.
+///   Arbitrary profiles are cross
+///   sections defined by an outer boundary as bounded curve, which may also
+///   include holes, defined by inner boundaries.
+///   Derived profiles, based on a
+///   transformation of a parent profile, are also part of the profile
+///   definitions available.
+///   In addition composite
+///   profiles can be defined, which include two or more profile definitions
+///   to define the resulting profile.
+/// 
+/// HISTORY  New class in IFC Release 1.5, the capabilities have been extended in IFC Release 2x.
+/// Profiles can now support swept surfaces and swept area solids with
+/// inner boundaries. It had been renamed from IfcAttDrivenProfileDef.
+/// 
+/// IFC2x4 CHANGE  Changed from ABSTRACT to non-abstract for uses which do not
+/// require an explicitly defined geometry.  Added inverse attributes HasProperties and HasExternalReference.
+/// 
+/// Use in material association
+/// 
+/// Beams, columns, and similarly shaped building elements and their type objects may
+/// be associated with a section profile definition, combined with material definition,
+/// by means of IfcRelAssociatesMaterial together with IfcMaterialProfileSet
+/// and IfcMaterialProfileSetUsage. This way, building elements and element types
+/// with same section and material can share a common section profile definition and
+/// association.
+/// 
+/// The profile definition in material association is required to be consistent with
+/// shape representations of the respective building elements.
+/// 
+/// A higher-level description of spatial aligment of the section profile of a member
+/// (such as centered, bottom-left, in the geometric centroid, and more) can be provided
+/// within IfcMaterialProfileSetUsage by means of a cardinal point reference.
+/// This can be used redundant to geometric data in order to convey design intent.
+/// 
+/// Use in shape models
+/// 
+/// Profile definitions are used within the geometry and geometric model
+/// resource to create either swept surfaces, swept area solids, or
+/// sectioned spines.
+/// 
+/// The purpose of the profile
+/// definition within the swept surfaces or swept area solids is to define
+/// a uniform cross section being swept:
+/// 
+/// along a line (extrusion) using IfcSurfaceOfLinearExtrusion or IfcExtrudedAreaSolid
+///   along a circular arc (revolution) using IfcSurfaceOfRevolution or IfcRevolvedAreaSolid
+///   along a directrix lying on a reference surface using IfcSurfaceCurveSweptAreaSolid
+/// 
+/// The purpose fo the profile
+/// definition within the sectioned spine is to define a varying cross
+/// sections at several positions along a spine curve. The subtype IfcDerivedProfileDef
+/// is particularly suited to provide the consecutive profiles to be based
+/// on transformations of the start profile and thus maintaining the
+/// identity of vertices and edges.
+/// 
+/// NOTE  Subtypes of the IfcProfileDef
+/// contain parameterized profiles (as subtypes of IfcParameterizedProfileDef)
+/// which establish their own 2D position coordinate system, profiles given
+/// by explicit curve geometry (either open or closed profiles) and two
+/// special types for composite profiles and derived profiles, based on a
+/// 2D Cartesian transformation.
+/// 
+/// An IfcProfileDef
+/// is treated as bounded area if it is used within swept area solids. In
+/// this case, the inside of the profile is part of the profile. The
+/// attribute ProfileType is set to AREA. An IfcProfileDef
+/// is treated as a curve if it is used within swept surfaces. In this
+/// case, the inside of the profile (if the curve is closed) is not part of
+/// the profile. The attribute ProfileType
+/// is set to CURVE.
+/// 
+/// Figure 320 illustrates use of parameterized profiles within a swept area solid.
+/// 
+/// Position
+/// The IfcProfileDef is defined within the underlying
+/// coordinate system which is defined by the swept surface or swept area solid
+/// that uses the profile definition. It is the xy plane
+/// 
+/// of IfcSweptSurface.Position or
+///   of IfcSweptAreaSolid.Position or
+///   of each list member of IfcSectionedSpine.CrossSectionPositions.
+/// 
+/// In the figure to the left, the z axis of the position coordinate system points outwards of the drawing plane.
+/// 
+/// Note: The subtype IfcParameterizedProfileDef optionally provides an additional 2D position coordinate system relative to the underlying coordinate system of the IfcProfileDef.
+/// 
+/// Sweeping
+/// 
+/// In the later use of the IfcProfileDef
+/// within the swept surface or swept area solid,  e.g. the IfcExtrudedAreaSolid
+/// (here used as an example), the profile boundaries (here based on the 2D
+/// position coordinate system of IfcParameterizedProfileDef)
+/// are placed within the xy plane of the 3D position coordinate system of
+/// the swept surface or swept area solid.
+/// 
+/// The profile is inserted into the underlying coordinate system either:
+/// 
+/// directly in case of using IfcArbitraryClosedProfileDef
+///   and IfcArbitraryOpenProfileDef,
+/// 
+/// through an intermediate position coordinate system in case of
+///   using IfcParameterizedProfileDef.
+/// 
+/// through an 2D Cartesian transformation operator (applied directly
+///   to the curve position when using arbitrary profile definitions,
+///   or applied to the position coordinate system when using parameterized
+///   profile definitions) in case of using IfcDerivedProfileDef.
+/// 
+/// when using IfcCompositeProfileDef the insertion depends on
+///   the subtype of the included sub-profiles.
+/// 
+/// Figure 320 — Profile sweeping
+/// 
+/// Profile types
+/// 
+/// Results of the different usage of the ProfileType attribute are demonstrated here. The ProfileType defines whether the inside (the bounded area) is part of the profile definition (Area) or not (Curve). Figure 321 illustrates the resulting area or curve depending on ProfileType.

+/// Profile specification by external reference
+/// 
+/// If the profile is standardized by a norm or a catalogue, a reference
+/// to this norm or catalogue should be provided by means of HasExternalReference.
+/// This inverse relationship is used to associate an IfcExternalReference (notably
+/// IfcClassificationReference or IfcLibraryReference) with the
+/// profile.
+/// 
+/// IfcClassificationReference is used to refer to a profile norm (a common standard or
+/// manufacturer's standard).  In this case,
+/// 
+/// IfcClassificationReference.ItemReference
+/// contains the formal profile designation from the norm.
+/// (On the other hand, IfcProfileDef.ProfileName contains a displayable name which may
+/// not necessarily be the same as the formal designation.)
+/// IfcClassificationReference.Name carries the short name of the profile norm.
+/// Optionally, the norm can be further described by
+/// IfcClassificationReference.ReferencedSource.
+/// 
+/// IfcLibraryReference is used to refer to a library which contains profile
+/// definitions. In this case,
+/// 
+/// IfcLibraryReference.ItemReference contains the identifier of the
+/// profile within the library and is meant to be machine-readable (in contrast to
+/// IfcProfileDef.ProfileName which should be human-readable).
+/// IfcLibraryReference.Location and .Name or .ReferencedLibrary

+/// 
+/// Direct instances of IfcProfileDef
+/// 
+/// Usually, only subtypes of IfcProfileDef should be instantiated.
+/// In some special cases, e.g. if the profile object is used for purposes

+/// 
+/// Texture maps are defined in a 2D coordinate system (s, t) that ranges from [0.0, 1.0] in both directions. The bottom edge of the image corresponds to the S-axis of the texture map, and left edge of the image corresponds to the T-axis of the texture map. The lower-left pixel of the image corresponds to s=0, t=0, and the top-right pixel of the image corresponds to s=1, t=1. Texture maps may be viewed as two dimensional colour functions that, given an (s, t) coordinate, return a colour value colour(s, t).
+/// 
+/// If multiple surface textures are included in the
+/// IfcSurfaceStyleWithTextures applying them to a geometric
+/// item, a mode and optional parameters can be included that blending

+/// The RepeatS and RepeatT Boolean flags control
+/// whether the texture map is repeated outside the [0.0, 1.0] texture
+/// coordinate range, when applied to a geometric surface, or clamped
+/// to lie within the [0.0, 1.0] range. The TextureTransform
+/// applies a 2D non-uniform transformation to the texture before it is
+/// applied to a geometric surface.
+/// The following definitions from ISO/IEC 19775-1 X3D Architecture
+/// and base components (X3D Specification)
+/// apply:
+/// 
+/// These parameters
+/// support changes to the size, orientation, and position of textures
+/// on shapes. Note that these operations appear reversed when viewed
+/// on the surface of geometry. For example, a scale value of (2
+/// 2) will scale the texture coordinates and have the net effect of
+/// shrinking the texture size by a factor of 2 (texture coordinates
+/// are twice as large and thus cause the texture to repeat). A
+/// translation of (0.5 0.0) translates the texture coordinates +.5
+/// units along the S-axis and has the net effect of translating the
+/// texture −0.5 along the S-axis on the geometry's surface. A
+/// rotation of π/2 of the texture coordinates results in a
+/// −π/2 rotation of the texture on the geometry.
+/// The center
+/// field specifies a translation offset in texture coordinate space
+/// about which the rotation and scale fields are
+/// applied. The scale field specifies a scaling factor in S and
+/// T of the texture coordinates about the center point.
+/// scale values shall be in the range (−∞,∞).
+/// The rotation field specifies a rotation in radians of the
+/// texture coordinates about the center point after the scale
+/// has been applied. A positive rotation value makes the texture
+/// coordinates rotate counterclockwise about the centre, thereby
+/// rotating the appearance of the texture itself clockwise. The

+/// IfcDerivedProfileDef defines the profile by transformation from the parent profile. The transformation is given by a two dimensional transformation operator. Transformation includes translation, rotation, mirror and scaling. The latter can be uniform or non uniform.

+/// 
+/// The transformation effects the position, rotation, mirroring or scale of the profile at the underlying coordinate system, i.e. the coordinate system defined by the swept surface or swept area solid that uses the profile definition. It is the xy plane of either: 
+/// 
+/// IfcSweptSurface.Position

+/// 
+/// or in case of sectioned spines the xy plane of each list member of IfcSectionedSpine.CrossSectionPositions. The position and potential rotation of the ParentProfile within the underlying coordinate system is taken into consideration before applying the Cartesian transformation operator.

+/// 
+/// HISTORY: New entity in IFC Release 2x.
+/// 
+/// Figure 316 illustrates examples of derived profiles.
+/// 
+/// Parameter
+/// The IfcDerivedProfileDef
+/// is defined using the IfcCartesianTransformationOperator2D
+/// (CTO), which is applied to the parent profile definition. 
+/// 
+/// Example
+/// The example shows an uniform scaling and a transformation
+/// of an IfcRectangleProfileDef
+/// to match the lower-left cardinal point. The attributes of the CTO are:
+/// 
+/// Axis1 = NIL (defaults to 1.,0.)
+///   Axis2 = NIL (defaults to 0.,1.)
+///   LocalOrigin = IfcCartesianPoint(,)
+///   Scale = 2.
+/// 
+/// Note: The ParentProfile has a Position
+/// = IfcCartesianPoint(,) already.
+/// 
+/// Parameter
+/// The IfcDerivedProfileDef is defined using
+/// non uniform transformationsby applying the IfcCartesianTransformationOperator2DnonUniform
+/// as a subtype of the 2D CTO.
+/// 
+/// Example
+/// The example shows a non-uniform scaling and a translation of an IfcRectangleProfileDef
+/// to match the lower-left cardinal point. The attributes of the CTO are:
+/// 
+/// Axis1 = NIL (defaults to 1.,0.)
+///   Axis2 = NIL (defaults to 0.,1.)
+///   LocalOrigin = IfcCartesianPoint(0.,<1/2 YDim)
+///   Scale  = 1.
+///   Scale2 = 2.
+/// 
+/// Note: The ParentProfile has a Position
+/// = IfcCartesianPoint(,) already.
+/// 
+/// Parameter
+/// The IfcDerivedProfileDef
+/// is defined using mirroring by applying the IfcCartesianTransformationOperator2D
+/// (CTO) to the parent profile.
+/// 
+/// Example
+/// The example shows a mirroring of an IfcLShapeProfileDef
+/// to match the centre cardinal point. The attributes of the CTO are:
+/// 
+/// Axis1 = (-1.,0.)
+///   Axis2 = NIL (defaults to 0.,1.)
+///   LocalOrigin = IfcCartesianPoint(0.,0.)
+///   Scale = NIL (defaults to 1.)
+/// 
+/// Note: The ParentProfile has a Position = IfcCartesianPoint(0.,0.).
+///

+/// relationship between two vertices. The domain of an edge, if
+/// present, is a finite, non-self-intersecting open curve in
+/// RM, that is, a connected 1-dimensional
+/// manifold. The bounds of an edge are two vertices, which need not

+/// Associated with an edge may be a geometric curve to locate the
+/// edge in a coordinate space; this is represented by the edge curve
+/// (IfcEdgeCurve) subtype. The curve shall be finite and
+/// non-self-intersecting within the domain of the edge. An edge is a

+/// M = E = 1, the Euler equation (1) reduces in the
+/// case to
+/// 
+/// where V = 1 or 2, and Ge = 1 or 0.

+/// - an edge has two vertices
+/// 
+/// - the vertices need not be distinct
+/// 
+/// - Equation (2) shall hold.
+/// 
+/// The geometry between the two

+/// Definition from ISO/CD 10303-42:1992: A face is a topological
+///   entity of dimensionality 2 corresponding to the intuitive notion of a piece of
+///   surface bounded by loops. Its domain, if present, is an oriented, connected,
+///   finite 2-manifold in Rm. A face domain shall not have handles
+///   but it may have holes, each hole bounded by a loop. The domain of the
+///   underlying geometry of the face, if present, does not contain its bounds, and 0
+///   < Ξ < ∞. 
+///   A face is represented by its bounding loops, which are defined as face
+///   bounds. A face has a topological normal n and the tangent to a loop is t. For a
+///   loop bounding a face with defined geometry, the cross product n x t points
+///   toward the interior of the face. That is, each loop runs counter-clockwise
+///   around the face when viewed from above, if we consider the normal n to point
+///   up. With each loop is associated a BOOLEAN flag to signify whether the loop
+///   direction is oriented with respect to the face normal (TRUE) or should be
+///   reversed (FALSE).  
+///   A face shall have at least one bound, and the loops shall not intersect.
+///   One loop is optionally distinguished as the outer loop of the face. If so, it
+///   establishes a preferred way of embedding the face domain in the plane, in which
+///   the other bounding loops of the face are inside the outer bound. Because the
+///   face domain is arcwise connected, no inner loop will contain any other loop.
+///   This is true regardless of which embedding in the plane is chosen.  
+///   The edges and vertices referenced by the loops of a face form a graph,
+///   of which the individual loops are the connected components. The Euler equation
+///   (1) for this graph becomes: 
+/// 
+/// where Gli is the graph genus of the

+/// The IfcGeometricRepresentationSubContext is used to define semantically distinguished representation types for different information content, dependent on the representation view and the target scale. It can be used to control the level of detail of the shape representation that is most applicable to this geometric representation context. addition the sub context is used to control the later appearance of the IfcShapeRepresentation within a plot view.

+/// RepresentationIdentifier="Axis" and
+/// RepresentationIdentifier="Body".
+/// 
+/// NOTE Refer to the implementation guide and agreements for
+/// more information on matching between building element geometry
+/// and material layer set usage.
+/// 
+/// The IfcMaterialLayerSetUsage is always assigned to an
+/// individual occurrence object only (i.e. to relevant subtypes of
+/// IfcElement). The IfcMaterialLayerSet, referenced by
+/// ForLayerSet can however be shared among several occurrence

+/// IfcMaterialLayerSet can be assigned to the type object.
+/// The assignment between asubtype of IfcElement and the
+/// IfcMaterialLayerSetUsage is handled by
+/// IfcRelAssociatesMaterial.
+/// 
+/// Use definition
+/// The IfcMaterialLayerSetUsage is primarily intended to
+/// be associated with planar building elements having a constant
+/// thickness. With further agreements on the interpretation of
+/// LayerSetDirection, the usage can be extended also to other
+/// cases, e.g. to curved building elements, provided that the
+/// material layer thicknesses are constant.
+/// Generally, an element may be layered in any of its primary
+/// directions, denoted by its x, y or z axis. The geometry use
+/// definitions at eachspecific types of building element will
+/// determine the applicableLayerSetDirection.
+/// 
+/// The following examples illustrate how the IfcMaterialLayerSetUsage attributes (LayerSetDirection, DirectionSense, OffsetFromReferenceLine) can
+/// be used in different cases. The normative material use definitions are documented at each element (how these shall be used).
+/// 
+/// Figure 286 shows an example of the use of IfcMaterialLayerSetUsage aligned to the axis of a wall.
+/// 
+/// EXAMPLE  For a standard wall with extruded
+/// geometric representation (vertical extrusion), the layer set
+/// direction will be perpendicular to extrusion direction,
+/// andcan be derived from the direction of the wall
+/// axis. With the DirectionSense(positive in
+/// this example) the individual IfcMaterialLayers are
+/// assigned consecutively right-to-left or left-to-right. For a
+/// curved wall, "direction denoting the wall thickness" can be
+/// derived from the direction of the wall axis, and it will remain
+/// perpendicular to the wall path. The
+/// DirectionSenseapplies as well.
+/// 
+/// NOTE  According to the IfcWallStandardCase material use
+/// definition the LayerSetDirection for
+/// IfcWallStandardCase is always AXIS2 (i.e. along the
+/// y-axis), as shown in this example.
+/// 
+/// Figure 286 — Material layer set usage for wall
+/// 
+/// Figure 287 shows an example of the use of IfcMaterialLayerSetUsage aligned to a slab.
+/// 
+/// EXAMPLE For a slab with perpendicular
+/// extruded geometric representation, the LayerSetDirection
+/// will coincide with the extrusion direction (in positive or
+/// negative sense). In this example, the material layer set base is
+/// the extruded profile and consistent with the
+/// IfcExtrudedAreaSolid.Position,with the
+/// DirectionSensebeing positive, the
+/// individual IfcMaterialLayers are built up from the base
+/// towards positive z direction in this case.
+/// 
+/// NOTE According to the IfcSlabStandardCase
+/// material use definition the LayerSetDirection for
+/// IfcSlabStandardCase is always AXIS3 (i.e. along the
+/// z-axis).
+/// 
+/// Figure 287 — Material layer set usage for slab
+/// 
+/// Figure 288 shows an example of the use of IfcMaterialLayerSetUsage aligned to a roof slab with non-perpendicular extrusion.
+/// 
+/// EXAMPLE For a slab with non-perpendicular
+/// extruded geometric representation, the guidelines above apply as
+/// well. The material layer thickness and the
+/// OffsetFromReferenceLine is always measured
+/// perpendicularly, even if the extrusion direction is not

+/// An IfcObjectDefinition is the generalization of any

+/// context is a specific kind of object definition as it provides the
+/// project or library context in which object types and object
+/// occurrences are defined.
+/// Objects are independent pieces of information that might contain

+/// 
+/// Assignment of other objects - an assignment relationship
+/// (IfcRelAssigns) that refers to other types of objects and
+/// creates a bi-directional association. The semantic of the
+/// assignment is established at the level of the subtypes of the
+/// general IfcRelAssigns relationship. There is no dependency
+/// implied a priori by the assignment.
+/// Association to external resources - an association
+/// relationship (IfcRelAssociates) that refers to external
+/// sources of information (most notably a classification or document)
+/// and creates a uni-directional association. There is no dependency
+/// implied by the association.
+/// Aggregation of other objects - an aggregation
+/// relationship (IfcRelAggregates) that establishes an
+/// unordered, spatial whole/part relation and creates a bi-directional
+/// relation. There is an implied dependency established.
+/// Nesting of other objects - a nesting relationship
+/// (IfcRelNests) that establishes an ordered, non-spatial
+/// whole/part relation and creates a bi-directional relation. There is
+/// an implied dependency established.
+/// Declaration within a context - a relationship
+/// (IfcRelDeclares) of the uppermost object definition within
+/// the object definition tree (e.g. the summary object within an
+/// object nesting tree) to the context (a project or project library).
+/// It applies the units, representation context and other context

+///   the shell member is a face without the orientation attribute. 
+///   The following combinatorial restrictions on open shells and geometrical
+///   restrictions on their domains are designed, together with the informal
+///   propositions, to ensure that any domain associated with an open shell is an
+///   orientable manifold. 
+/// 
+/// Each face reference shall be unique.

+///   vertices. The domain of an open shell, if present, contains all edges and
+///   vertices of its faces. 
+/// 
+/// NOTE  Note that this is slightly different from the
+///   definition of a face domain, which includes none of its bounds. For example, a
+///   face domain may exclude an isolated point or line segment. An open shell domain
+///   may not. (See the algorithm for computing below.) 
+///   In the current IFC Release only poly loops
+///   (IfcPolyLoop) are defined for bounds of face bound

+/// 
+/// A one-component image specifies one-byte hexadecimal value representing the intensity of the image. For example, 0xFF is full intensity in hexadecimal (255 in decimal), 0x00 is no intensity (0 in decimal).
+/// A two-component image specifies the intensity in the first
+/// (high) byte and the alpha opacity in the second (low) byte.

One of the constraints has a benchmark of 'GREATERTHANOREQUALTO' whilst the second has a benchmark of 'LESSTHANOREQUALTO'. This means that the constraint must lie between these two bounding values. The relating constraint is instantiated as an objective named as 'Weight Constraint' and qualified as a SPECIFICATION constraint. The two related constraints are both specified as metrics since they can have specific values.

+/// Transparency is the ratio of the transmitted flux in a solid angle of 2 * PI sr (one hemisphere). It is a simple colour filtration that does not account for refraction. 
+///   Transmission factor of a material is the ratio of transmitted flux in a given solid angle to the transmitted flux of a completely diffuse material with 100% transmission in the same solid angle. It is the portion of light that goes through the material and may be refracted.

+/// Definition from CSS1 (W3C Recommendation): Setting font properties will be among the most common uses of style sheets. Unfortunately, there exists no well-defined and universally accepted taxonomy for classifying fonts, and terms that apply to one font family may not be appropriate for others. For example, 'italic' is commonly used to label slanted text, but slanted text may also be labeled as being Oblique, Slanted, Incline, Cursive or Kursiv. Therefore it is not a simple problem to map typical font selection properties to a specific font.
+/// 
+/// Font matching
+/// Because there is no accepted, universal taxonomy of font properties, matching of properties to font faces must be done carefully. The properties are matched in a well-defined order to ensure that the results of this matching process are as consistent as possible across user agents (assuming that the same library of font faces is presented to each of them).
+/// 
+/// The user agent makes (or
+/// accesses) a database of relevant CSS1
+/// properties of all the fonts of which the UA is aware. The UA may be
+/// aware of a font because it has been installed locally or it has been
+/// previously downloaded over the web. If there are two fonts with
+/// exactly the same properties, one of them is ignored. 
+///   At a given element and for
+/// each character in that element, the UA
+/// assembles the font-properties applicable to that element. Using the
+/// complete set of properties, the UA uses the 'font-family' property to
+/// choose a tentative font family. The remaining properties are tested
+/// against the family according to the matching criteria described with
+/// each property. If there are matches for all the remaining properties,
+/// then that is the matching font face for the given element. 
+///   If there is no matching font
+/// face within the 'font-family' being
+/// processed by step 2, and if there is a next alternative 'font-family'
+/// in the font set, then repeat step 2 with the next alternative
+/// 'font-family'. 
+///   If there is a matching font
+/// face, but it doesn't contain a glyph
+/// for the current character, and if there is a next alternative
+/// 'font-family' in the font sets, then repeat step 2 with the next
+/// alternative 'font-family'.  
+///   If there is no font within
+/// the family selected in 2, then use a

+/// match that can be obtained within the default font. 
+/// 
+/// (The above algorithm can be
+/// optimized to avoid having to revisit
+/// the CSS1 properties for each character.)
+/// 
+/// The per-property matching rules
+/// from (2) above are as follows:
+/// 
+/// 'font-style' is tried first.
+/// 'italic'
+/// will be satisfied if there is either a face in the UA's font database
+/// labeled with the CSS keyword 'italic' (preferred) or 'oblique'.
+/// Otherwise the values must be matched exactly or font-style will fail. 
+///   'font-variant' is tried
+/// next. 'normal'
+/// matches a font not labeled as 'small-caps'; 'small-caps' matches (1) a
+/// font labeled as 'small-caps', (2) a font in which the small caps are
+/// synthesized, or (3) a font where all lowercase letters are replaced by
+/// upper case letters. A small-caps font may be synthesized by
+/// electronically scaling uppercase letters from a normal font. 
+///   'font-weight' is matched next, it will never fail. (See 'font-weight' below.) 
+///   'font-size' must be matched within a
+/// UA-dependent margin of tolerance. (Typically, sizes for scalable fonts
+/// are rounded to the nearest whole pixel, while the tolerance for
+/// bitmapped fonts could be as large as 20%.) Further computations, are
+/// based on the 'font-size' value that is used, not the one that is specified.

+/// Definition from ISO/CD 10303-42:1992: A closed shell is a shell
+///   of the dimensionality 2 which typically serves as a bound for a region in R3. A
+///   closed shell has no boundary, and has non-zero finite extent. If the shell has
+///   a domain with coordinate space R3, it divides that space into two connected
+///   regions, one finite and the other infinite. In this case, the topological
+///   normal of the shell is defined as being directed from the finite to the
+///   infinite region.  
+///   The shell is represented by a collection of faces. The domain of the
+///   shell, if present, contains all those faces, together with their bounds.
+///   Associated with each face in the shell is a logical value which indicates
+///   whether the face normal agrees with (TRUE) or is opposed to (FALSE) the shell
+///   normal. The logical value can be applied directly as a BOOLEAN attribute of an
+///   oriented face, or be defaulted to TRUE if the shell boundary attribute member
+///   is a face without the orientation attribute.  
+///   The combinatorial restrictions on closed shells and geometrical
+///   restrictions on their domains are designed to ensure that any domain associated
+///   with a closed shell is a closed, orientable manifold. The domain of a closed
+///   shell, if present, is a connected, closed, oriented 2-manifold. It is always
+///   topologically equivalent to an H-fold torus for some H
+///   ³ 0. The number H is referred to as the
+///   surface genus of the shell. If a shell of genus H has a domain within
+///   coordinate space R3, then the finite region of space inside
+///   it is topologically equivalent to a solid ball with H tunnels drilled
+///   through it. 
+///   The Euler equation (7) applies with B=0, because in this case
+///   there are no holes. As in the case of open shells, the surface genus H
+///   may not be known a priori, but shall be an integer ³ 0. Thus a necessary, but not sufficient, condition
+///   for a well-formed closed shell is the following: 
+/// 
+/// In the current IFC Release only poly loops
+///   (IfcPolyLoop) are defined for bounds of face bound
+///   (IfcFaceBound). This will allow for faceted B-rep only.

+/// IfcConstructionResourceType is an abstract generalization of the different resource types used in construction projects, mainly labor, material, equipment and product resource types, plus subcontracted resource types and aggregations such as a crew resource type.

+/// A resource type represents a model of "use of something" and does not necessarily correspond to a specific type of object such as a person or vehicle, but represents possible usages of such objects such as general labor or an equipment fleet.  A resource type can either represent usage in general (consumption attributes defined but no task type assignment) or a task-specific resource type (production attributes defined and having an IfcTask assignment).
+/// 
+/// A construction resource type captures common productivities and cost rates for applying resources to particular task types.
+/// 
+/// HISTORY: New entity in IFC2x4.
+/// 
+/// Composition use definition
+/// Resource types may be decomposed into nested resource types indicating productivities when applying the resource to specific task types using the IfcRelNests relationship where IfcRelNests.RelatingObject refers to the general resource type and IfcRelNests.RelatedObjects refers to one or more task-specific productivities.  For example, an IfcLaborResourceType may be defined for "Carpenter" which may have a nested IfcLaborResourceType for "Carpenter - Wall Framing" and another nested IfcLaborResourceType for "Carpenter - Drywall", each of which may have productivities based according to specific task types (IfcTaskType). 
+/// 
+/// Assignment use definition
+/// Resource types may be assigned to process types (IfcTypeProcess subtypes) using the IfcRelAssignsToProcess relationship as shown in Figure 193.  Such relationship indicates that the resource type applies to the process type for the use indicated (e.g. IfcTaskType.PredefinedType).  Such relationship enables a scenario of placing an IfcProduct of a particular IfcTypeProduct, querying for a set of IfcTypeProcess process types for constructing such product (e.g. IfcTaskTypeEnum.CONSTRUCTION), querying each IfcTypeProcess for a set of IfcTypeResource resource types for carrying out the process, and finally choosing an IfcTypeProcess and IfcTypeResource combination resulting in the shortest time for instantiated IfcTask occurrence(s) and/or lowest-cost for instantiated IfcConstructionResource occurrence(s).

+/// 'Netto-Grundfläche' (net floor area), and the method of
+/// measurement might be accordingly 'DIN277-2' (German industry norm

+/// Definition from ISO/CD 10303-46:1992: The fill area style hatching defines a styled pattern of curves for hatching an annotation fill area or a surface.
+/// 
+/// The IfcFillAreaStyleHatching is used to define simple, vector-based hatching patterns, based on styled straight lines. The curve font, color and thickness is given by the HatchLineAppearance, the angle by the HatchLineAngle and the distance to the next hatch line by StartOfNextHatchLine, being either an offset distance or a vector.
+/// 
+/// NOTE  If the hatch pattern involves two (potentially crossing) rows of hatch lines, then two instances of IfcFillAreaStyleHatching should be assigned to the IfcFillAreaStyle. Both share the same (virtual) point of origin of the hatching that is used by the reference hatch line (or the PointOfReferenceHatchLine if there is an offset).
+/// 
+/// For better control of the hatching appearance, when using hatch lines with other fonts then continuous, the PatternStart allows to offset the start of the curve font pattern along the reference hatch line (if not given, the PatternStart is at zero distance from the virtual point of origin). If the reference hatch line does not go through the origin (of the virtual hatching coordinate system), it can be offset by using the PatternStart PointOfReferenceHatchLine.
+/// 
+/// NOTE  The coordinates of the PatternStart and the PointOfReferenceHatchLine are given relative to the assumed 0., 0. virtual point of origin at which the hatch pattern is later positioned by the FillStyleTarget point at IfcAnnotationFillAreaOccurrence. The measure values are given in global drawing length units and apply to the target plot scale for the scale depended representation subcontext.
+/// 
+/// NOTE  The use of PointOfReferenceHatchLine is deprecated.
+/// 
+/// Figure 292 illustrates hatch attributes.
+/// 
+/// Example 1
+/// This example shows simple hatching given by using a curve font "continuous" at HatchLineAppearance.
+/// 
+/// The distance of hatch lines is given by a positive length measure. The
+/// angle (here 45' if measures in degree) is provided by HatchLineAngle.
+/// 
+/// The PatternStart is
+/// set to NIL ($) in this example.  Example 2
+/// This shows hatching from example 1 with using a different curve font at HatchLineAppearance.
+///   The distance of hatch lines is given by a positive
+/// length measure, therefore the font pattern start is at a point at the
+/// next hatch line given by a vector being perpendicular to the point of
+/// origin at the reference hatch line.  The
+/// PatternStart is set to NIL ($) in this example.
+///   Example 3
+/// This example uses hatching from example 2 with a vector to determine the pattern start of the next hatch lines. 
+/// The pattern start is the beginning of the first visual curve font pattern segment at IfcCurveFont.CurveFont.  The PatternStart is set to NIL ($) in this example.
+///   Example 4
+/// This example uses hatching from example 3 where the pattern start is offset from the point of origin at the reference hatch line. That is, the first visible curve font pattern segment now does not start at the point of origin at the reference hatch line.
+/// 
+/// Example 5
+/// This example uses hatching from example 4 where the hatch pattern is shifted against the underlying coordinate system. 
+/// The point that is mapped to the insertion point of the IfcAnnotationFillAreaOccurrence now has an X and Y offset from the start of the reference hatch line. That is, the reference hatch line now does not go through the insertion point of the hatching.    
+///   Example 6
+/// This example shows use of IfcFillAreaStyleHatching attributes for two IfcFillAreaStyleHatching's within one IfcFillAreaStyle. Note that the PatternStart now displaces both the reference hatch line from the point of origin and the start of the curve pattern. This can be used in cases when more than one IfcFillAreaStyleHatching is used in an IfcFillAreaStyle in order to place rows of hatch lines with an offset from each other.

+/// the geometry of a face shall be 2-manifold embeddable in the
+/// plane within the domain of the face. In other words, it shall be
+/// connected, oriented, finite, non-self-intersecting, and of
+/// surface genus 0.
+/// Faces do not intersect except along their boundaries. Each
+/// edge along the boundary of a face is shared by at most one other
+/// face in the assemblage. The assemblage of edges in the B-rep do
+/// not intersect except at their boundaries (i.e., vertices). The

+/// shall be arcwise connected and shall not self intersect or
+/// overlap within the domain of the edge. The geometry of an edge
+/// shall be consistent with the geometry of the faces of which it
+/// forms a partial bound. The geometry used to define a vertex shall
+/// be consistent with the geometry of the faces and edges of which
+/// it forms a partial bound.
+/// A B-rep is represented by one or more closed shells which
+/// shall be disjoint. One shell, the outer, shall completely enclose
+/// all the other shells and no other shell may enclose a shell. The
+/// facility to define a B-rep with one or more internal voids is
+/// provided by a subtype. The following version of the Euler formula
+/// shall be satisfied, where V, E, F, Ll and S are the

+/// Objects can be named, using the inherited Name

+/// given using the inherited Description attribute. The
+/// ObjectType attribute is used:

+/// Assignment of other objects - an assignment
+/// relationship that refers to other types of objects. See supertype

+/// Aggregation of other objects - an aggregation
+/// relationship that establishes a whole/part relation. Objects can
+/// either be a whole, or a part, or both. See supertype
+/// IfcObjectDefinition for more information.
+/// 
+/// Assignment of a type : IsTypedBy - a definition
+/// relationship IfcRelDefinesByType that uses a type
+/// definition to define the common characteristics of this
+/// occurrences, potentially including the common shape
+/// representation and common properties of all object occurrences

+/// Having a control applied: assigned using

+/// 
+/// Being assigned to a process: assigned using
+/// IfcRelAssignsToProcess linking the IfcProduct to an

+/// 
+/// An example of this

+/// The IfcProject is used to reference the root of the spatial structure of a building (that serves as the primary project breakdown and is required to be hierarchical).

+/// IfcProject shall not be decomposed into any parts.

+/// (IfcSite || IfcBuilding) by
+/// IfcRelAggregates.RelatingObject. The IfcSite or
+/// IfcBuilding referenced shall be the root of the spatial
+/// structure.
+/// 
+/// The IfcProject is also the context for other information about the construction project such as a work plan. Non-product structures are assigned by their first level object to IfcProject using the IfcRelDeclares relationship.
+/// 
+/// The IfcProject provides the context for spatial elements and the associated products, and for work plans (or other non-product based) descriptions of the construction project. It is handled by two distinct relationship objects as shown in Figure 3.
+/// NOTE   The spatial structure and the schedule structure can be decomposed. For example the IfcBuilding can be decomposed into IfcBuildingStorey's, and the IfcWorkPlan can be decomposed into IfcWorkSchedule's.
+/// NOTE   The products and tasks can be decomposed further. For example the IfcCurtainWall can be decomposed into IfcMember and IfcPlate, the IfcTask can be decomposed into other IfcTask's.
+/// NOTE   The products and tasks can have direct linking relationships. For example the IfcCurtainWall can be assigned to a IfcTask as an input or output for a construction schedule.
+/// NOTE   The anomaly to use the composition structure through IfcRelAggregates for assigning the uppermost spatial container to IfcProject is due to upward compatibility reasons with earlier releases of this standard.

+///   IfcTankType (subtype of IfcTypeObject),
+///   defining the specific information for all occurencies of

+///   subtype of IfcRelAssociates to the type
+///   information.

+/// EXAMPLE 2  The classification information
+///   for a particular space within a building may the associated
+///   to the IfcSpace object (subtype of
+///   IfcObject), defining a particular occurrence of

+/// IfcRelSequence is used to describe the logical

+///   This logical relationship identifies that there is a
+///   predecessor or relating process and a successor or related
+///   process. In IFC, there may be one predecessor and one
+///   successor in the relationship. Many occurrences of
+///   IfcRelSequence may exist to describe the sequence
+///   relationships of a predecessor task with many successor
+///   tasks or of many predecessor tasks with one successor task,
+///   thus enabling a m:n sequence relationship between tasks.
+///   Please note that sequence relationships always should stay
+///   within the limits of a directed, non-cyclic graph.
+/// 
+/// A sequence type may be set for a sequence. For tasks
+///   assigned to a work schedule, it is expected that the
+///   sequence type will be asserted. For a process map, where
+///   the sequence relationship between processes is simply a
+///   logical flow, it need not be asserted.
+/// 
+/// A time lag may be assigned to a sequence, and the sequence
+///   type defines the way in which the time lag applies to the
+///   sequence either as a ratio or percentage of time duration
+///   (e.g. start successor task when predecessor is 50%
+///   complete) or as a time measure (e.g. start successor task 1
+///   week after commencement of the predecessor task). Care
+///   should be used when assigning a time lag to a sequence
+///   depending on the setting of the sequence type since there
+///   is no checking that the time lag value is in keeping with

+/// IfcResource contains the information needed to represent the costs, schedule, and other impacts from the use of a thing in a process. It is not intended to use IfcResource to model the general properties of the things themselves, while an optional linkage from IfcResource to the things to be used can be specified (specifically, the relationship from subtypes of IfcResource to IfcProduct through the IfcRelAssignsToResource relationship).  
+/// 
+/// There are two basic intended uses of IfcResource. First, if the attributes of the thing are not needed for the purpose of the use of IfcResource, or the types of things are not explicitly modeled in IFC yet, then the linkage between the resource and the thing doesn't have to be instantiated in the system. That is, the attributes of IfcResource (or its subtypes) alone are sufficient to represent the use of the thing as a resource for the purpose of the project.  
+/// 
+/// EXAMPLE: construction equipment such as earth-moving vehicles or tools are not currently modeled within the IFC. For the purpose of estimating and scheduling, these can be represented using subtypes of IfcResource alone.
+/// 
+/// Second, if the attributes of the thing are needed for the use of IfcResource objects, and they are modeled explicitly as objects, then the IfcResource instances can be linked to the instances of the type of the things being referenced. Things that might be used as resources and that are already modeled in the IFC include physical products, people and organizations, and materials.

+/// Definition from IAI: The abstract entity IfcStructuralActivity combines the definition of actions (such as forces, displacements, etc.) and reactions (support reactions, internal forces, deflections, etc.) which are specified by using the basic load definitions from the IfcStructuralLoadResource.
+/// 
+/// The differentiation between actions and reactions is realized by instantiating objects either from subclasses of IfcStructuralAction or IfcStructuralReaction respectively.  They inherit commonly needed attributes from the abstract superclass IfcStructuralActivity, notably the relationship which connects actions or reactions with connections, analysis members, or elements (subtypes of IfcStructuralItem or IfcElement).
+/// 
+/// NOTE  Instances of IfcStructuralActivity which are connected with an IfcElement are subject to agreements outside the scope of this specification.
+/// 
+/// NOTE  The semantics of IfcStructuralActivity are only fully defined
+/// if an activity instance is connected with exactly one structural item.  The inverse attribute
+/// AssignedToStructuralItem can only be empty in incomplete models or in conceptual models
+/// which are not yet ready for analysis.
+/// 
+/// HISTORY: New entity in IFC 2x2.
+/// 
+/// IFC 2x4 change:  Cardinality of attribute
+/// AssignedToStructuralItem relaxed from 1 to 0..1 in order to allow for schema-compliant
+/// incomplete models as well as conceptual models without load—item relationships.
+/// 
+/// Coordinate Systems:
+/// 
+/// The following coordinate systems are distinguished:
+/// 
+/// The so-called global coordinate system is the coordinate system shared by all items and activities which are grouped in a common IfcStructuralAnalysisModel.  This coordinate system is established by an ObjectPlacement.  (This coordinate system is not necessarily the same as the IfcProject's world coordinate system.)
+///   The so-called local coordinate system is a coordinate system local to a structural item (connection or member).  This coordinate system is established by a Representation in conjunction with further use definitions and attributes of subtypes of IfcStructuralItem.
+/// 
+/// Representation items in topology representations are always given within the ObjectPlacement, i.e. in so-called global coordinates (global with respect to the IfcStructuralAnalysisModel to which this activity belongs).
+/// 
+/// Locations of the load objects in the AppliedLoad attribute (if of type IfcStructuralLoadConfiguration) are always given in local coordinates.
+/// 
+/// Directions of the load objects in the AppliedLoad attribute refer to global or local coordinates according to the GlobalOrLocal attribute.
+/// 
+/// The ObjectPlacement and Representation are sometimes not explicitly instantiated; instead they may be implied as described below.  Global and local coordinate systems are then determined in the same way as with explicit placement and representation.
+/// 
+/// Topology Use Definitions:
+/// 
+/// Instances of IfcStructuralActivity which are connected with a structural item of same dimensionality, i.e.
+/// 
+/// a point action or reaction connected with a point item (IfcStructuralPointConnection),
+///   a curve action or reaction connected with a curve item (IfcStructuralCurveConnection, IfcStructuralCurveMember), or
+///   a surface action or reaction connected with a surface item (IfcStructuralSurfaceConnection, IfcStructuralSurfaceMember) and which acts on the entire surface of the item and is not specified by isocontours
+/// 
+/// shall not have an ObjectPlacement nor a Representation.  It is implied that the placement and representation of the IfcStructuralActivity is the same as the ones of the IfcStructuralItem.
+/// 
+/// Instances of IfcStructuralActivity which are connected with
+/// 
+/// a curve item (IfcStructuralCurveConnection, IfcStructuralCurveMember) and act on a point of the item, or
+///   a surface item (IfcStructuralSurfaceConnection, IfcStructuralSurfaceMember) and act on a point or on a curve or on a part of the surface of the item
+/// 
+/// shall have a topology representation as specified below.  It includes a placement and a product representation. The IfcProductRepresentation shall be given by an item in a Representation of type IfcTopologyRepresentation.
+/// 
+/// Instances of IfcStructuralActivity which are connected with
+/// 
+/// a surface item (IfcStructuralSurfaceConnection, IfcStructuralSurfaceMember) and are specified by isocontours
+/// 
+/// shall have a shape representation as specified below.  It includes a placement and a product representation. The IfcProductRepresentation shall be given by items in a Representation of type IfcShapeRepresentation.  Shape representation and topology representation may be combined.
+/// 
+/// Local Placement
+/// 
+/// The local placement for IfcStructuralActivity is defined in its supertype IfcProduct.  It is defined by the IfcLocalPlacement, which establishes a global coordinate system which shall be common to all items and activities in an IfcStructuralAnalysisModel.
+/// 
+/// Topology Representation
+/// 
+/// Instances of IfcStructuralActivity which act on parts of a surface item shall have a topology representation given by a face with underlying surface geometry, IfcFaceSurface, which should be the single item of IfcTopologyRepresentation.Items.  The surface establishes a local coordinate system of the activity:
+/// 
+/// The origin of surface parameters u,v is the origin of the local coordinate system.
+///   The local x and y directions follow the tangents on the surface and are in parallel with and directed like u and v respectively.
+///   The local z direction is in parallel with and directed like the surface normal.
+/// 
+/// RepresentationIdentifier: 'Reference'
+///   RepresentationType: 'Face'
+/// 
+/// Instances of IfcStructuralActivity which act on a curve on a surface item shall have a topology representation given by an edge (IfcEdge or subtype), which should be the single item of IfcTopologyRepresentation.Items.  The curve geometry shall be compatible with the surface geometry of the connected item.  In conjunction with this surface, the curve establishes a local coordinate system of the activity:
+/// 
+/// The origin of the curve parameter u is the origin of the local coordinate system.
+///   The local x direction follows the tangent on the curve and is directed like u.
+///   The local z direction is in parallel with and directed like the surface normal of the connected surface item.
+///   The local x,y,z directions form a right-handed Cartesian coordinate system.
+/// 
+/// RepresentationIdentifier: 'Reference'
+///   RepresentationType: 'Edge'
+/// 
+/// NOTE  While an IfcEdge (or IfcOrientedEdge with underlying IfcEdge) does not provide an explicit underlying curve geometry, it may be used to imply an underlying straight line as reference curve with the origin of the curve parameter at the start vertex point.
+/// 
+/// Instances of IfcStructuralActivity which act on a single point on a curve or surface item shall have a topology representation given by an IfcVertexPoint, which should be the single item of IfcTopologyRepresentation.Items.  The point geometry shall be compatible with the curve or surface geometry of the connected item.  The local coordinate system of the activity is oriented by the curve or surface geometry of the connected item as described above for activities with edge or face topology.

+/// 
+/// Instances of IfcStructuralActivity which act on a surface item and are specified by isocontours (level sets) shall have a shape representation given by a set of curves on a surface, IfcPCurve.

+/// 
+/// Type use definition
+/// 
+/// IfcTask defines the anticipated or actual occurrence
+///   of any task; common information about task types is handled
+///   by IfcTaskType. The IfcTaskType (if present)
+///   may establish the common type name, usage (or predefined)
+///   type, common set of properties, and common product
+///   assignment using IfcRelAssignsToProduct. The
+///   IfcTaskType is attached using the
+///   IfcRelDefinesByType.RelatingType objectified
+///   relationship and is accessible by the inverse
+///   IsTypedBy attribute. Special type information
+///   relating to a task occurrence is asserted using
+///   IfcTask.ObjectType (inherited from
+///   IfcObject). Examples that may be used include fixed
+///   duration, fixed unit or fixed work. IfcTask can be
+///   aggregated to a task type in order to specify a task
+///   sequence or any time related information, e.g. the duration
+///   of a task. Please see the documentation of
+///   IfcTaskType for further information.
+/// 
+/// Attribute use definition
+/// 
+/// Each occurrence of IfcTask is given a name that is
+///   indicative of its content (IfcRoot.Name). A textual
+///   description of the task may be provided and this may be
+///   further elaborated by a narrative long description
+///   (IfcProcess.LongDescription). A work method may be
+///   declared for the method of work used in carrying out a
+///   task. A task is identified as being either a milestone task
+///   or not. A milestone task is defined by the marker
+///   IsMilestone. and has no duration. A status and
+///   priority for each task may also be set.
+/// 
+/// Property set use definition
+/// 
+/// The property sets relating to IfcTask are defined by
+///   IfcPropertySet and attached by the
+///   IfcRelDefinesByProperties relationship. They are
+///   accessible by the inverse IsDefinedBy relationship.
+///   Such property sets may define task parameters. No property
+///   sets for IfcTask are currently defined by IFC.
+/// 
+/// Connectivity Use Definition
+/// 
+/// The relationship IfcRelSequence is used to indicate
+///   control flow. An IfcTask as a successor to an
+///   IfcTask indicates logical sequence how these tasks
+///   should be performed. IfcTask's can be triggered or
+///   can trigger IfcEvent's, which is also defined
+///   through the relationship IfcRelSequence.
+/// 
+/// Composition use definition
+/// 
+/// IfcTask may be contained within an IfcTask
+///   using the IfcRelNests relationship. An
+///   IfcTask may in turn nest other IfcTask,
+///   IfcProcedure or IfcEvent entities. Such
+///   nesting indicates decomposed level of detail. From IFC2x4
+///   onwards it is required to have a summary task (root of all
+///   tasks), which is used to define a link to the work plan or
+///   work schedule. All subtasks of the summary tasks are then
+///   implicitly linked to this work plan or work schedule.
+///   Please note that the summary task is used for data
+///   organization and not meant to store typical task
+///   information as defined by the user. It is therefore
+///   recommended that the summary task is hidden from the user
+///   to avoid confusion. Please also note that
+///   IfcRelNests is used to show the dependency between
+///   regular tasks and recurring task definitions (please see
+///   the section about time and duration use definitions).
+/// 
+/// As shown in Figure 13, the installation of a number of items of equipment within a
+///   particular space may be the subject of a single task which
+///   is identified as 'fix equipment in space 123'.
+///   IfcTask represents the occurrence of a work
+///   performance of a type of process in a construction plan.
+/// 
+/// Figure 13 — Task visualization
+/// 
+/// A task may nest other tasks as sub-items; the nesting
+///   relationship is modeled by IfcRelNests as shown in Figure 14. For example,
+///   the construction of a stud wall may be designated as a
+///   nesting task named 'install wall #1' including other tasks
+///   such as 'install dry wall', 'install studs', 'wall taping',
+///   and 'erect wall' as sub-processes. A value that indicates
+///   the relative tree view position of the task (in comparison
+///   to the tree view position of other tasks and the task
+///   hierarchy defined by IfcRelNests).
+///   The task order information that is used for viewing
+///   purposes is derived from the order defined by the
+///   IfcRelNests relationship and thus is independent of
+///   the logical task order defined through
+///   IfcRelSequence. The hierarchy and order defined
+///   through IfcRelNests enables to order the tasks in a
+///   tree view or list view structure.
+/// 
+/// Figure 14 — Task nesting relationships
+/// 
+/// Time and duration use definition
+/// 
+/// Compared to previous IFC releases, basic task time
+///   information (scheduled start time, scheduled finish
+///   time, duration) is now directly attached to IfcTask
+///   through the TaskTime attribute. Regular tasks are
+///   defined through IfcTaskTime. Recurring tasks are
+///   defined through IfcTaskTimeRecurring. In case a
+///   regular task is derived from a recurring task both tasks
+///   should be linked together through a IfcRelNests
+///   relationship, where IfcRelNests.IsNestedBy points to
+///   the recurring task and IfcRelNests.Nests points to
+///   all regular tasks that have been derived from the recurring
+///   task.
+/// 
+/// Assignment use definition
+/// 
+/// Occurrences of IfcTask may be assigned to an
+///   IfcWorkControl (either a work plan or a work
+///   schedule) through IfcRelAssignsToControl. From
+///   IFC2x4 onwards it is suggested to use the 'summary task'
+///   (root element of the task hierarchy that is required for
+///   task management purposes) to assign all subtask to a work
+///   plan or work schedule. Resources used by tasks are assigned
+///   by IfcRelAssignsToProcess. Quantities of resources
+///   consumed by the task are dealt with by defining the
+///   IfcElementQuantity for the resource and not at the
+///   instance of IfcTask. Please note that the
+///   IfcRelAssignsTasks relationship class has been
+///   removed in IFC2x4 and is no longer available.
+/// 
+/// An IfcTask may be assigned a Work Breakdown
+///   Structure (WBS) code. A WBS code is dealt with as a
+///   classification of task and is associated to a task
+///   occurrence using the IfcRelAssociatesClassification
+///   relationship class. As well as being to designate the code,
+///   the classification structure of the IFC model also enables
+///   the source of the work breakdown structure classification
+///   to be identified.
+/// 
+/// Constraint use definition
+/// 
+/// Constraints may be applied to a task to indicate fixed task
+///   duration, fixed start or fixed finish (see Figure 15). The relationship
+///   IfcRelAssociatesConstraint is used where
+///   RelatingConstraint points to an IfcMetric and
+///   RelatedObjects includes the IfcTask.
+///   IfcRelAssociatesConstraint.Name identifies the
+///   attribute to be constrained using a period (".") to
+///   dereference; for example, "TaskTime.ScheduleStart" refers
+///   to the ScheduleStart attribute on the
+///   IfcTaskTime entity referenced on the TaskTime
+///   attribute. The following attributes may be constrained:
+/// 
+/// 'TaskTime.ScheduleDuration': Indicate fixed
+///   duration of task with ConstraintGrade=HARD and
+///   Benchmark=EQUALTO such that changes to an assigned
+///   IfcConstructionResource.ResourceTime.ScheduleWork
+///   should impact
+///   IfcConstructionResource.ResourceTime.ScheduleUsage,
+///   and vice-versa.
+/// 
+/// 'TaskTime.ScheduleStart': Indicate constrained
+///   start date with ConstraintGrade=HARD and Benchmark of
+///   EQUALTO, GREATERTHANOREQUALTO, or LESSTHANOREQUALTO to
+///   indicate "must start on", "start no earlier than" or
+///   "start no later than" respectively where
+///   IfcMetric.DataValue indicates the specific
+///   IfcDateTime. Use SOFT constraint having LESSTHAN
+///   benchmark to indicate "start as soon as possible".
+/// 
+/// 'TaskTime.ScheduleFinish': Indicate constrained
+///   finish date with ConstraintGrade=HARD and Benchmark of
+///   EQUALTO, GREATERTHANOREQUALTO, or LESSTHANOREQUALTO to
+///   indicate "must finish on", "finish no earlier than" or
+///   "finish no later than" respectively where
+///   IfcMetric.DateValue indicates the specific
+///   IfcDateTime. Use SOFT constraint having
+///   GREATERTHAN benchmark to indicate "finish as late as
+///   possible".
+/// 
+/// A "manual scheduled task" is indicated with
+///   ConstraintGrade=HARD and Benchmark=EQUALTO for both
+///   TaskTime.ScheduleStart and
+///   TaskTime.ScheduleFinish.
+/// 
+/// Figure 15 — Task constraints
+/// 
+/// Use Definition to represent other activities
+/// 
+/// The use definitions for IfcTask have been generalised to
+///   represent other activities as well, including actitities
+///   that had been defined by own entities in previous IFC
+///   releases. This includes
+/// 
+/// Order actions
+///   Move operations
+/// 
+/// IfcTask represents an order that might be carried
+///   out by a Helpdesk acting the role of interface for the
+///   organization between the facility user and the functional
+///   requirement of fulfilling their needs. The actual task
+///   represented by the IfcTask entity is turning a
+///   request into an order and initiating the action that will
+///   enable the order to be completed. The
+///   IfcProjectOrder or one of its subtypes including
+///   maintenance work order, is related to the IfcTask
+///   using IfcRelAssignsToControl.
+/// 
+/// IfcTask can also be used to describe an activity
+///   that moves people, groups within an organization or
+///   complete organizations together with their associated
+///   furniture and equipment from one place to another. It thus
+///   replaces the previous IFC entity IfcMove. The functionality
+///   is represented in IfcTask as follows:
+/// 
+/// Move from: The place from which actors and their
+///   associated equipment are moving.
+///   Use IfcRelAssignsToProcess where
+///   RelatingProcess points to the task and
+///   RelatedObjects holds the location(s) from which to
+///   move.
+///   Move to: The place to which actors and their
+///   associated equipment are moving.
+///   Use IfcRelAssignsToProduct where
+///   RelatedObjects points to the task(s) and
+///   RelatingProduct points to the location to which to
+///   move.
+///   Punch list: A list of points concerning a move that
+///   require attention.
+///   Use LongDescription or else identify sub-tasks to
+///   track punch list items individually via IfcRelNests.

+/// Definition from IAI: An annotation is a graphical

+/// 
+/// NOTE Additional presentation information (often

+///   related to a particular product representation is
+///   included within the IfcProductDefinitionShape

+///   presentation information, that cannot be directly related
+///   to a single product, have to be wrapped within the

+/// 
+/// If available, the annotation should be related to the

+/// The IfcAnnotation can provide specific 0D, 1D, and
+///   2D geometric items as representation of the annotation,
+///   offering annotation point, curves, and surfaces.
+/// 
+/// 'Annotation point' is an annotation provided by a
+///   point that has additional semantic. The inherited
+///   attribute ObjectType should be used to capture the
+///   type of point annotation, some predefined values are:
+/// 
+/// 'Survey': A survey point has a set of
+///   cartesian coordinates determined by its location at
+///   point. These coordinates are determined relative to the
+///   coordinates of a reference point, which acts as the
+///   datum for the survey. The difference in elevation of
+///   the survey points enables terrain to be determined.
+/// 
+/// 'Annotation curve' is an annotation provided by a
+///   curve that has additional semantic. The inherited
+///   attribute ObjectType should be used to capture the
+///   type of curve annotation, some predefined values are:
+/// 
+/// 'ContourLine': A line of constant
+///   elevation typically used on geographic maps where the
+///   spacing of lines at constant intervals of elevation may
+///   be used as an indication of slope.
+/// 
+/// 'IsoBar': A line of constant pressure
+///   typically used on weather maps or to show pressure
+///   gradient in spaces, chambers or externally.

+/// 'IsoLux': A line of constant illumination
+///   typically used to show the distribution of illumination
+///   levels and/or daylighting in a space or externally.
+/// 
+/// 'IsoTherm': A line of constant temperature
+///   typically used to show the distribution and effect of

+///   spatial structure element at a higher level, referenced
+///   by that.
+/// 
+/// If the relative placement is not used, the absolute
+///   placement is defined within the world coordinate system.
+/// 
+/// Geometric Representations
+/// 
+/// The standard representation of IfcAnnotation is
+///   defined using 'Annotation2D', when using 2D geometry,

+/// 
+/// Spatial Structure Use Definition
+/// The IfcBuildingStorey is used to build the spatial
+/// structure of a building (that serves as the primary project
+/// breakdown and is required to be hierarchical). The spatial
+/// structure elements are linked together by using the objectified
+/// relationship IfcRelAggregates. The
+/// IfcBuildingStoreyreferences them by its inverse
+/// relationships:
+/// 
+/// IfcBuildingStorey.Decomposes -- referencing
+/// (IfcBuilding || IfcBuildingStorey) by
+/// IfcRelAggregates.RelatingObject, If it refers to another
+/// instance ofIfcBuildingStorey, the referenced
+/// IfcBuildingStorey needs to have a different and higher

+/// IfcBuildingStorey has ELEMENT), or ELEMENT (if the other
+/// IfcBuildingStorey has PARTIAL).
+/// IfcBuildingStorey.IsDecomposedBy -- referencing
+/// (IfcBuildingStorey || IfcSpace) by

+/// IfcBuildingStorey needs to have a different and lower
+/// CompositionType, i.e. ELEMENT (if the other
+/// IfcBuildingStorey has COMPLEX), or PARTIAL (if the other
+/// IfcBuildingStorey has ELEMENT).
+/// 
+/// If there are building elements and/or other elements directly
+/// related to the IfcBuildingStorey (like most building
+/// elements, such as walls, columns, etc.), they are associated with
+/// the IfcBuildingStorey by using the objectified
+/// relationship IfcRelContainedInSpatialStructure. The
+/// IfcBuildingStorey references them by its inverse
+/// relationship:
+/// 
+/// IfcBuildingStorey.ContainsElements -- referencing any
+/// subtype of IfcProduct (with the exception of other spatial
+/// structure element) by
+/// IfcRelContainedInSpatialStructure.RelatedElements.
+/// 
+/// Figure 25 shows the IfcBuildingStorey as part of the

+/// NOTE Detailed requirements on mandatory element
+/// containment and placement structure relationships are given in
+/// view definitions and implementer agreements.
+/// 
+/// Figure 25 — Building storey composition
+/// 
+/// Elements can also be referenced in an
+/// IfcBuildingStorey, for example, if they span through several
+/// storeys. This is expressed by using the objectified relationship
+/// IfcRelReferencedInSpatialStructure. Systems, such as
+/// building service or electrical distribution systems, zonal
+/// systems, or structural analysis systems, relate to

+/// Geometry Use Definitions
+/// The geometric representation of IfcBuildingStorey is
+/// given by the IfcProductDefinitionShape and
+/// IfcLocalPlacement, allowing multiple geometric
+/// representation.
+/// Local Placement
+/// The local placement for IfcBuildingStorey is defined in
+/// its supertype IfcProduct. It is defined by the
+/// IfcLocalPlacement, which defines the local coordinate
+/// system that is referenced by all geometric representations.
+/// 
+/// The PlacementRelTo relationship of
+/// IfcLocalPlacement shall point (if relative placement is
+/// used) to the IfcSpatialStructureElement of type
+/// IfcBuilding, or of type IfcBuildingStorey (e.g. to
+/// position a building storey relative to a building storey complex,
+/// or a partial building storey to a building storey).
+/// If the relative placement is not used, the absolute placement
+/// is defined within the world coordinate system.
+/// 
+/// Geometric Representations
+/// Currently, the use of a 2D 'FootPrint' representation of type
+/// 'GeometricCurveSet' and a 3D 'Body' representation of type 'Brep'
+/// is supported.
+/// 
+/// NOTE The independent geometric representation of
+/// IfcBuildingStorey may not be required or allowed in
+/// certain view definitions. In those cases only the contained
+/// elements and spaces have an independent geometric
+/// representation.
+/// 
+/// Foot Print Representation
+/// The foot print representation of IfcBuildingStorey is
+/// given by either a single 2D curve (such as IfcPolyline or
+/// IfcCompositeCurve), or by a list of 2D curves (in case of
+/// inner boundaries), if the building storey has an independent

+/// representation of IfcBuildingStorey is:
+/// 
+/// IfcShapeRepresentation.RepresentationIdentifier =

+/// Type use definition
+/// IfcConstructionResource defines the occurrence of any construction resource; common information about construction resource types is handled by IfcConstructionResourceType. The IfcConstructionResourceType (if present) may establish the common type name, common properties, common cost rates, and common productivities applied to specific task types. The IfcConstructionResourceType is attached using the IfcRelDefinesByType.RelatingType objectified relationship and is accessible by the inverse IsTypedBy attribute as shown in Figure 186.
+/// The resource type may provide shared productivity and cost information, allowing tasks and resources to be selected according to lowest cost and/or shortest duration. Given an IfcProduct of a particular IfcTypeProduct type, an IfcTypeProcess may be selected from those assigned to the product type using IfcRelAssignsToProduct, and an IfcTypeResource may be selected from those assigned to the process type using IfcRelAssignsToProcess. Then IfcTask and IfcConstructionResource occurrences may be instantiated from the type definitions, applying productivitity and rate information to assigned quantities to calculate ResourceTime.ScheduleWork. Task durations can then be calculated by dividing ResourceTime.ScheduleWork by ResourceTime.ScheduleUsage.
+/// 
+/// Figure 186 — Construction resource type use
+/// 
+/// Composition use definition
+/// Resources may be decomposed into allocation pools using the IfcRelNests relationship as shown in Figure 187. For example, an IfcLaborResource for "Electrician" may be decomposed into three task-specific IfcLaborResource objects: "Electrical Rough-in", "First Floor Circuits", and "Second Floor Circuits". Both relating and related sides may represent the same ResourceTime.ScheduleUsage quantity (for example, 6 workers time-shared), or the related side may break out ResourceTime.ScheduleUsage quantities for reserved use (for example, 4 workers and 2 workers). 
+/// A common scenario is two nesting levels where the first-level resources have no task assignments; while second-level resources have specific task assignments indicating that the resource is subdivided into allocations for specific tasks. While the model allows unlimited nesting of resources, implementer agreements may restrict to two nesting levels with task assignments specifically at the second level.
+/// 
+/// Figure 187 — Construction resource composition use
+/// 
+/// Declaration use definition
+/// A root-level resource (specifically IfcCrewResource or IfcSubContractResource) is declared within the project by IfcRelDeclares where RelatingContext refers to the single IfcProject and RelatedObjects refers to one or more IfcConstructionResource, and other root-level objects within the project.
+/// 
+/// Assignment use definition
+/// A resource may be assigned to an actor by IfcRelAssignsToActor where RelatingActor refers to an IfcActor and RelatedObjects refers to one or more IfcConstructionResource or other objects. Such relationship indicates the actor responsible for allocating the resource such as partitioning into task-specific allocations, delegating to other actors, and/or scheduling over time. Note that this assignment does not indicate the person or organization performing the work; that is indicated by IfcRelAssignsToResource. The actor responsible for the resource may or may not be the same as any actor(s) performing work.
+/// A resource may be assigned to a control by IfcRelAssignsToControl where RelatingProduct refers to an IfcControl and RelatedObjects refers to one or more IfcConstructionResource or other objects. Most commonly an IfcWorkCalendar is assigned indicating availability of the resource, where such calendar is nested within a base calendar or an IfcWorkPlan which in turn is assigned to the IfcProject.
+/// A resource may be assigned to a group by IfcRelAssignsToGroup where RelatingGroup refers to an IfcGroup and RelatedObjects refers to one or more IfcConstructionResource or other objects. Most commonly an IfcAsset is assigned indicating the asset to be tracked, where such asset is nested within an IfcInventory which in turn is assigned to the IfcProject.
+/// A resource may be assigned to a product by IfcRelAssignsToProduct where RelatingProduct refers to an IfcProduct and RelatedObjects refers to one or more IfcConstructionResource or other objects. Most commonly an IfcElement subtype is assigned indicating the product to be constructed, where such product is connected to a spatial
+/// structure which in turn is aggregated within the IfcProject.
+/// A resource may be assigned to a process by IfcRelAssignsToProcess where RelatingProcess refers to an IfcProcess and RelatedObjects refers to one or more IfcConstructionResource or other objects. Most commonly an IfcTask is assigned indicating the task to be performed by the resource, where such task is nested within a summary task which in turn is assigned to the IfcProject. 
+/// A resource may have assignments of other objects using IfcRelAssignsToResource where RelatingResource refers to the IfcConstructionResource and RelatedObjects refers to one or more objects such as IfcActor or IfcProduct subtypes. This relationship indicates specific objects assigned to fulfill resource usage.

The relationship IfcRelAssociatesConstraint is used where RelatingConstraint points to an IfcMetric and RelatedObjects includes the IfcConstructionResource as shown in Figure 189. IfcRelAssociatesConstraint.Name identifies the attribute to be constrained using a period (".") to dereference; for example, "ResourceTime.ScheduleWork" refers to the ScheduleWork attribute on the IfcResourceTime entity referenced on the ResourceTime attribute. The following attributes may be constrained:
+/// 
+/// 'ResourceTime.ScheduleUsage': Indicate fixed usage (e.g.
+/// simultaneous workers) with ConstraintGrade=HARD and
+/// Benchmark=EQUALTO such that changes to
+/// ResourceTime.ScheduleWork should impact the assigned

+/// 
+/// Figure 189 — Construction resource constraint use
+/// 
+/// Time series use definition
+/// Time series may be applied to a resource to indicate the break-out of attribute values over time. The relationship IfcRelAssociatesTimeSeries is used where RelatingTimeSeries points to an IfcTimeSeries (either IfcRegularTimeSeries or IfcIrregularTimeSeries) and RelatedObjects includes the IfcConstructionResource as shown in Figure 190. IfcRelAssociatesTimeSeries.Name identifies the attribute to be constrained using a period (".") to dereference; for example, "ResourceTime.ScheduleWork" refers to the ScheduleWork attribute on the IfcResourceTime entity referenced on the ResourceTime attribute. Refer to attribute descriptions on IfcResourceTime for attribute-specific usage.
+/// Each IfcTimeSeriesValue indicates a LIST of values, where the sequence of the value corresponds to the IfcCostValue at IfcConstructionResource.CostRatesConsumed. For example, if CostRatesConsumed has two IfcCostValue items in the LIST, "Standard" and "Overtime", then IfcTimeSeriesValue(IfcDuration('T8H0M0S'),IfcDuration('T2H0M0S')) would indicate 8 hours at Standard rate and 2 hours at Overtime rate. If the list of values at IfcTimeSeriesValue.ListValues is less than the size of CostRatesConsumed, then subsequent values are considered to be zero.

The Subtotal component has IfcCostValue.CostType set to an asterisk ('*') which indicates it is the sum of all nested values of all categories.

+/// Figure 157 — Cost composition
+/// 
+/// Assignment Use Definition
+/// 
+/// An IfcCostItem can be calculated based on quantities from objects through its relationship to IfcRelAssignsToControl.
+/// 
+/// For quantity-based costing, IfcElement, IfcTask, or IfcResource occurrence subtypes may be used.  Multiple elements may be assigned of the same or different types, using IfcPhysicalQuantity entities defined at each object.  Each IfcPhysicalQuantity type must be identical (for example, all values are IfcAreaQuantity) such that they can be added together.
+/// 
+/// For rate-based costing (specifically for IfcCostScheduleTypeEnum.SCHEDULEOFRATES), a single IfcTypeProduct, IfcTypeProcess, or IfcTypeResource subtype may be used to reflect rates for occurrences of such types.  This enables the possibility to generate a quantity-based cost schedule for occurrences based on types with rate-based cost schedules.
+/// 
+/// IfcRelAssignsToControl is also used in the opposite direction to link the root IfcCostItem to an IfcCostSchedule where RelatingControl is the IfcCostSchedule. 
+/// 
+/// Figure 158 illustrates cost item assignment derived from building elements.  The IfcRelAssignsToControl relationship indicates building elements for which quantities are derived.  Not shown, costs may also be derived from building elements by traversing assignment relationships from the assigned IfcProduct to IfcProcess to IfcResource, where all costs ultimately originate at resources.  It is also possible for cost items to have assignments from processes or resources directly.

Inclusion within IfcProject indicates the type is editable within the direct project and may be available to other referencing projects that may incorporate the type.  Inclusion within IfcProjectLibrary indicates the type is incorporated from a referenced project.  Default units and coordinate systems (used for representations, materials, and property sets) are indicated by the declaring project or library.
+/// 
+/// Classification Use Definition
+/// The IfcDistributionFlowElementType may be classified using IfcRelAssociatesClassification where RelatingClassification refers to an IfcClassificationReference indicating a classification notation. Classifications may refer to industry standards such as MasterFormat, OmniFormat, or UniFormat.  Classifications may also refer to organization-specific, project-specific, or system-specific designations.  Classification reference identification schemes are described by IfcClassification.ReferenceTokens.
+/// 
+/// Document Use Definition
+/// The IfcDistributionFlowElementType may be documented using IfcRelAssociatesDocument where RelatingDocument refers to an IfcDocumentReference indicating content within a document, or IfcDocumentInformation indicating an entire document. Document information may refer to arbitrary attachments such as text or multimedia, while document references may refer to items within particular formats (such as XML element IDs) where there is need to synchronize document information with model information.  Document reference identification schemes depend on the particular document format.
+/// 
+/// Library Use Definition
+/// The IfcDistributionFlowElementType may be published to a model server using IfcRelAssociatesLibrary where RelatingLibrary refers to an IfcLibraryReference indicating the unique identification within the published project.  If the published project is IFC format, then IfcLibraryReference.Identification shall match IfcRoot.GlobalID of the published (master) project, using the same encoding as described for IfcGloballyUniqueId.  Multiple library references may be provided to indicate alternate names and descriptions for particular languages.  If the element type is declared within IfcProject, then IfcLibraryInformation.Location and IfcLibraryInformation.Version indicate the URL and version as last published.  If the element type is declared within IfcProjectLibrary, then the library information indicates the location and version of the definition as last retrieved.

+/// 
+/// Figure 148 — Distribution flow element library
+/// 
+/// Composition Use Definition
+/// The IfcDistributionFlowElementType may be decomposed into components using IfcRelAggregates where RelatingObject refers to the enclosing IfcDistributionFlowElementType and RelatedObjects contains one or more components.  For example, a cable type may be decomposed into wires.  Standard types for composition are defined at occurrences for subtypes.
+/// 
+/// Connection Use Definition
+/// The IfcDistributionFlowElementType may be connected to other objects as follows using the indicated relationship:
+/// 
+/// IfcDistributionPort (IfcRelConnectsPortToElement) : Indicates port definitions on the element to be instantiated at occurrences.  Standard port names, types, and directions are defined at occurrences for subtypes.
+/// 
+/// Assignment Use Definition
+///   The IfcDistributionFlowElementType may have assignments of its own using the IfcRelAssignsToProduct relationship where RelatingProduct refers to the IfcDistributionFlowElementType and RelatedObjects contains one or more objects of the following types: 
+/// 
+/// IfcTaskType: Indicates task types available to purchase, install, renovate, demolish, operate, or otherwise act upon occurrences of the element type.  Such task types may be instantiated as task occurrences assigned to occurrences of the element type.  Prices (such as for purchasing or shipping) may be established by resource types assigned to task types.
+/// IfcProcedureType: Indicates procedure types available to operate occurrences of the element type.  Such procedure types may be instantiated as procedure occurrences assigned to occurrences of the element type.
+/// IfcEventType: Indicates event types available to be raised by occurrences of the element, sequenced by procedures to be followed.  Such event types may be instantiated as event occurrences assigned to occurrences of the element type.
+/// 
+/// Material Use Definition
+/// The material of the IfcDistributionFlowElementType is defined using one of the following entities:
+/// 
+/// IfcMaterialProfileSet: For elements having a constant cross-section, this defines the material profile which may be used to generate the 'Body' representation at occurrences (for parametric definitions not having representation), or for analysis purposes.
+/// IfcMaterialConstituentSet: For elements containing multiple materials, this indicates materials at named aspects.
+/// 
+/// IfcMaterial: For elements comprised of a single material, this indicates the material.
+/// 
+/// The material is attached by the RelatingMaterial attribute on the IfcRelAssociatesMaterial relationship.  It is accessible by the HasAssociations inverse attribute.
+/// 
+/// Representation Use Definition
+/// The following shape representations are supported for subtypes of IfcDistributionFlowElementType, distinguished by IfcShapeRepresentation.RepresentationIdentifier:
+/// 
+/// 'Axis': Represents the 3D flow path of the item having IfcShapeRepresentation.RepresentationType of 'Curve3D' and containing a single IfcBoundedCurve subtype such as IfcPolyline, IfcTrimmedCurve, or IfcCompositeCurve.  For elements containing directional ports (IfcDistributionPort with FlowDirection of SOURCE or SINK), the direction of the curve indicates direction of flow where a SINK port is positioned at the start of the curve and a SOURCE port is positioned at the end of the curve.  This representation is most applicable to flow segment types (pipes, ducts, cables), however may be used at other elements to define a primary flow path if applicable. 
+/// 
+/// 'Footprint': Represents the 2D footprint outline of the item having IfcShapeRepresentation.RepresentationType of 'GeometricCurveSet' and containing a single IfcGeometricCurveSet consisting of one or more IfcCurve subtypes such as IfcPolyline, IfcTrimmedCurve, IfcCompositeCurve, or IfcCircle.
+/// 
+/// 'Body': Represents the 3D shape of the item having IfcShapeRepresentation.RepresentationType of 'SurfaceModel', 'SolidModel', or any solid model specializations including 'Brep', 'AdvancedBrep', 'SweptSolid', 'AdvancedSweptSolid', 'CSG', 'Clipping', or 'SectionedSpine').
+/// 
+/// 'Clearance': Represents the 3D clearance volume of the item having RepresentationType of 'Surface3D'.  Such clearance region indicates space that should not intersect with the 'Body' representation between element occurrences, though may intersect with the 'Clearance' representation of other element occurrences.  The particular use of clearance space may be for safety, maintenance, or other purpose.
+/// 
+/// 'Lighting': Represents the light emission of the item having IfcShapeRepresentation.RepresentationType of 'LightSource' and containing one or more IfcLightSource subtypes.  This representation is most applicable to lamps and light fixtures, however may be used at other elements that emit light.
+/// 
+/// If an element type is defined parametrically (such as a flow segment type defining common material profile but no particular length or path), then no representations shall be asserted at the type.
+/// 
+/// NOTE: The product representations are defined as representation maps (at the level of the supertype IfcTypeProduct, which get assigned by an element occurrence instance through the IfcShapeRepresentation.Item[1] being an IfcMappedItem.

+/// Geometry use definitions
+/// The IfcDoorLiningProperties does not hold its own
+/// geometric representation. However it defines parameters which can

+/// project) as shown in Figure 172.
+/// The parameters of the IfcDoorLiningProperties define a
+/// standard door lining, including (if given) a threshold and a
+/// transom. The outer boundary of the lining is determined by the
+/// occurrence parameter assigned to the IfcDoor, which
+/// inserts the IfcDoorStyle.
+/// 
+/// The lining is applied to the left,
+/// right and upper side of the opening reveal. The parameters are:
+/// 
+/// LiningDepth, if omited, equal to
+/// wall thickness - this only takes effect if a value for
+/// LiningThickness is given. If both parameters are not
+/// given, then there is no lining.
+/// LiningThickness
+/// LiningToPanelOffsetX
+/// LiningToPanelOffsetY
+/// 
+/// NOTE Parameters added in
+/// IFC2x4.
+/// 
+/// The lining can only cover part of
+/// the opening reveal.
+/// 
+/// LiningOffset : given if lining edge has an offset to
+/// the x axis of the local placement.
+/// 
+/// NOTE In addition to theLiningOffset,
+/// the local placement of the IfcDoor can already have an
+/// offset to the wall edge and thereby shift the lining along the y
+/// axis. The actual position of the lining is calculated from the
+/// origin of the local placement along the positive y axis with the
+/// distance given by LiningOffset.
+/// 
+/// The lining may include a casing,
+/// which covers part of the wall faces around the opening. The
+/// casing covers the left, right and upper side of the lining on
+/// both sides of the wall. The parameters are:
+/// 
+/// CasingDepth
+/// CasingThickness
+/// 
+/// The lining may include a threshold,
+/// which covers the bottom side of the opening. The parameters are:
+/// 
+/// ThresholdDepth
+/// if omited, equal to wall thickness - this
+/// only takes effect if a value for ThresholdThickness is
+/// given. If both parameters are not given, then there is no
+/// threshold.
+/// ThresholdThickness
+/// ThresholdOffset (not shown in figure): given, if the
+/// threshold edge has an offset to the x axis of the local
+/// placement.
+/// 
+/// The lining may have a transom which
+/// separates the door panel from a window panel. The transom, if
+/// given, is defined by:
+/// 
+/// TransomOffset : a parallel edge to the x axis of the
+/// local placement
+/// TransomThickness
+/// 
+/// The depth of the transom is identical to the depth of the
+/// lining and not given as separate parameter.
+/// 
+/// Figure 172 — Door lining properties
+/// 
+/// NOTE LiningDepth describes the length of the lining along the reveal of the door opening. It can be given by an absolute value if the door lining has a specific depth depending on the door style. However often it is equal to the wall thickness. If the same door style is used (like the same type of single swing door), but inserted into different walls with different thicknesses, it would be necessary to create a special door style for each wall thickness. Therefore several CAD systems allow to set the value to "automatically aligned" to wall thickness. This should be exchanged by leaving the optional attribute LiningDepth unassigned. The same agreement applies to ThresholdDepth.

+/// 
+/// IfcEvent is used to capture information about

+///   identify e.g. a point at which a message containing
+///   information may be issued or at which a rule or constraint
+///   is invoked.
+/// 
+/// Type use definition
+/// 
+/// IfcEvent defines the anticipated or actual occurrence of
+///   any event; common information about event types is handled
+///   by IfcEventType. The IfcEventType (if present) may
+///   establish the common type name, usage (or predefined) type,
+///   common set of properties, and common product assignment
+///   using IfcRelAssignsToProduct. The IfcEventType is attached
+///   using the IfcRelDefinesByType.RelatingType objectified
+///   relationship and is accessible by the inverse IsTypedBy
+///   attribute.
+/// 
+/// Property set use definition
+/// 
+/// The property sets relating to IfcEvent are defined by
+///   IfcPropertySet and attached by the
+///   IfcRelDefinesByProperties relationship. They are accessible
+///   by the inverse IsDefinedBy relationship. Such property sets
+///   may define event parameters. No property sets for IfcEvent
+///   are currently defined by IFC.
+/// 
+/// Connectivity use definition
+/// 
+/// The relationship IfcRelSequence is used to indicate control
+///   flow. An IfcEvent as a predecessor
+///   (IfcRelSequence.RelatingProcess) indicates that the
+///   succeeding process (typically IfcProcedure or IfcTask) is
+///   triggered in response to the event. An IfcEvent as a
+///   successor (IfcRelSequence.RelatedProcess) indicates that
+///   the completion of the preceeding process causes the event
+///   to be triggered. As events have zero duration, the
+///   IfcRelSequence.SequenceType attribute has no effect on an
+///   IfcEvent but still applies to the opposite end of the
+///   relationship if IfcTask is used.
+/// 
+/// Composition use definition
+/// 
+/// IfcEvent may be contained within an IfcTask using the
+///   IfcRelNests relationship. The event is considered active
+///   during the time period of the enclosing task (including any
+///   assigned IfcWorkCalendar); that is such event may be
+///   triggered within the task time period but not outside of
+///   it. As an IfcEvent is considered to be atomic, no use is
+///   anticipated for nesting processes inside the event.
+/// 
+/// Assignment use definition
+/// 
+/// An IfcEvent may be assigned to an IfcWorkCalendar to
+///   indicate times when such event is active using
+///   IfcRelAssignsToControl; otherwise the effective calendar is
+///   determined by the nearest IfcProcess ancestor with a
+///   calendar assigned.
+/// 
+/// For building operation scenarios, IfcEvent may be assigned
+///   to a product (IfcElement subtype) using
+///   IfcRelAssignsToProduct to indicate a specific product
+///   occurrence that sources the event. For example, an
+///   IfcSensor for a motion sensor may have a "Motion Sensed"
+///   event. If the IfcEvent is defined by an IfcEventType and
+///   the IfcEventType is assigned to a product type (using
+///   IfcRelAssignsToProduct), then the IfcEvent must be assigned
+///   to one or more occurrences of the specified product type

+/// NOTE The term "feature" has a predefined meaning in a

+/// 
+/// In contrary to the aggregation, as used in
+/// IfcElementAssembly, that defines the aggregate as a
+/// container element, that has equally treated parts, the feature
+/// concept introduced by IfcFeatureElement defines the master
+/// element with subordinate parts as additions, or with voids or
+/// cut-outs as subtractions.
+/// 
+/// HISTORY New entity in Release
+/// IFC2x Edition 2.
+/// NOTE The entity is introduced as an

+/// 
+/// Geometry Use Definition
+/// The geometric representation of IfcFeatureElement is
+/// given by the IfcProductDefinitionShape, allowing multiple

+/// Local Placement
+/// The local placement for IfcFeatureElement is defined in

+/// The PlacementRelTo relationship of
+/// IfcLocalPlacement shall point (if given) to the local
+/// placement of the master IfcElement (its relevant
+/// subtypes), which is associated to the IfcFeatureElement by
+/// the appropriate relationship object.
+/// If the relative placement is not used, the absolute placement
+/// is defined within the world coordinate system.
+/// 
+/// Geometric Representations
+/// Any IfcFeatureElement can be represented by one or
+/// several geometric representations. A detailed specification is
+/// introduced at the level of subtypes. Only the general
+/// representation identifier 'Box' with representation type
+/// 'BoundingBox', and representation identifier 'Body' with
+/// representation type 'Brep' are defined here.
+/// Box Representation
+/// Any IfcFeatureElement may be represented as a bounding
+/// box, which shows the maximum extend of the body within the
+/// coordinated system established by the IfcLocalPlacement.
+/// The bounding box representation is the simplest geometric
+/// representation available. The following attribute values for the
+/// IfcShapeRepresentation holding this geometric
+/// representation shall be used:

+/// Brep Representation Type
+/// Any IfcFeatureElement (so far no further constraints
+/// are defined at the level of its subtypes) may be represented as a
+/// single or multiple Boundary Representation elements (which are

+/// HISTORY: New Entity in IFC Release 2.0.  Base type and documentation extended in IFC 2x4.
+/// 
+/// IFC2x4 CHANGE: The attribute Skillset has been deleted; use LongDescription to describe the skillset.
+/// 
+/// The purpose of an IfcLaborResource is to identify a skillset that may be required or used. The skillset identified may be (for instance) chargehand, foreman, labourer, plumbers mate etc. and provides a designation of a particular level of skill. It can be used to identify the generic type of labor resource that is required for a purpose without having to be specific about the actor (person or organization) providing the resource occurrence. It may be particularly useful when creating an overall plan for a process or processes. For instance, within maintenance or work planning there may be a known task that needs to be done which is planned to require a 'chargehand pipe fitter'. There may be several such labor resources available and so the need to identify which will be used is not necessary at the planning stage.
+/// 
+/// At a later stage, individual actors can be determined for the labor resources. This is achieved through specifiying the actor through IfcActor. The actor is then identified as the labour resource occurrence through the IfcRelAssignsToResource.RelatedResource attribute. The IfcLaborResource provides the IfcRelAssignsToResource.RelatingResource attribute. 
+/// 
+/// Use definitions for composition, assignment, constraints, time series, and baselines are described at the base type IfcConstructionResource.
+/// 
+/// Type use definition
+/// IfcLaborResource defines the occurrence of any labor resource; common information about labor resource types is handled by IfcLaborResourceType.  The IfcLaborResourceType (if present) may establish the common type name, common properties, common productivities for various task types using IfcRelAssignsToProcess.  The IfcLaborResourceType is attached using the IfcRelDefinesByType.RelatingType objectified relationship and is accessible by the inverse IsTypedBy attribute.
+/// 
+/// Quantity use definition
+/// The quantities relating to the IfcLaborResource are defined by IfcElementQuantity and attached by the IfcRelDefinesByProperties relationship. It is accessible by the inverse IsDefinedBy relationship. The following base quantities are defined and should be exchanged with the IfcElementQuantity.Name = 'BaseQuantities'. Other quantities can be defined being subjected to local standard of measurement with another string value assigned to Name and a value provided for MethodOfMeasurement.
+///

+/// of the IfcMemberType, then the occurrence property
+/// overrides the type property.
+/// 
+/// Pset_MemberCommon: common property set for all
+/// member types.
+/// 
+/// Profile Use Definition:
+/// The shared profile definition is defined by assigning an
+/// IfcMaterialProfileSet (see material use definition above).
+/// The IfcMaterialProfile refers to the subtype of

+/// occurrence, if used. It is only applicable if the
+/// IfcMemberType has only occurrences of type
+/// IfcMemberStandardCase (see definition of
+/// IfcMemberStandardCase for further information).
+/// NOTE The attribute ProfileName of the
+/// IfcProfileDef subtype, referenced in
+/// IfcMaterialProfile should contain a standardized profile
+/// name according to local standards. However, an additional
+/// geometric representation of the profile is necessary (e.g. as
+/// IfcExtrudedAreaSolid). An importing application is allowed
+/// to check for the existence of the profile name: in case of
+/// identifying it as a standardized name, the corresponding profile
+/// geometry and possibly other cross sectional properties can be
+/// read from a library. Otherwise the geometric representation and
+/// possible non geometric IfcProfileProperties have to be
+/// used.
+/// Geometry Use Definition:
+/// The IfcMemberType may define the shared geometric
+/// representation for all member occurrences. The
+/// RepresentationMaps attribute refers to a list of
+/// IfcRepresentationMap's, that allow for multiple geometric
+/// representations (e.g. with IfcShaperepresentation's having

+/// occurrences of type IfcMember (See geometric use
+/// definition of IfcMember for further information).
+/// NOTE If the IfcMemberType has an
+/// associated IfcMaterialProfileSet, then no shared geometric
+/// representation shall be provided.
+/// NOTE The product shape representations are
+/// defined as RepresentationMaps (attribute of the supertype

+/// The opening element stands for

+/// The IFC specification provides two entities for opening

+/// 
+/// IfcOpeningStandardCase is used for all openings that

+/// relative to the voided elements and the extrusion direction is
+/// perpendicular to the plane of the element (horizontally for

+/// 
+/// NOTE View definitions or implementer

+/// IfcOpeningStandardCase
+/// There are two different types of opening elements:
+/// 
+/// an opening, where the thickness of the opening is greater or

+/// a recess or niche, where the thickness of the recess is
+/// smaller than the thickness of the element.
+/// 
+/// The attribute PredefinedType should be used to capture

+/// 
+/// NOTE Until IFC2x3 the information had been
+/// provided by the inherited attribute
+/// ObjectType.
+/// An IfcOpeningElement has to be inserted into an

+/// Quantity Use Definition:

+/// this case a valid value for MethodOfMeasurement has to be
+/// provided.
+/// 
+/// Qto_OpeningElementBaseQuantities: base
+/// quantities for all opening occurrences.
+/// 
+/// Containment Use Definition
+/// The IfcOpeningElement shall not participate in the

+/// Local Placement
+/// The local placement for IfcOpeningElement is defined in

+/// The property sets relating to this entity are defined by IfcPropertySet and attached by the IfcRelDefinesByProperties relationship. They are accessible by the IsDefinedBy inverse attribute.  Refer to the documentation at the supertype IfcControl and ancestors for inherited property set definitions. 
+/// The following property set definitions are applicable to this entity: 
+/// Pset_Permit 
+/// 
+/// Declaration Use Definition 
+/// The IfcPermit may be declared within the project using the IfcRelDeclares relationship where RelatingContext refers to the single IfcProject and RelatedDefinitions contains the IfcPermit.  Alternatively, if the IfcPermit is aggregated within an IfcWorkPlan, then it shall not have a direct declaration relationship (whereas the containing work plan may have a declaration relationship). 
+/// 
+/// Composition Use Definition 
+/// The IfcPermit may be aggregated into components using IfcRelAggregates where RelatingObject refers to the enclosing IfcPermit and RelatedObjects contains one or more components.  Aggregation use is defined for the following predefined types:
+/// 
+/// ACCESS: May contain IfcWorkCalendar components.  A work calendar may indicate the time period of the permit and allowed times when work may be performed.  Such work calendar may have assigned resources indicating equipment or labor permitted at various times. 
+/// WORK: May contain IfcWorkSchedule components.  A work schedule may indicate tasks and scheduled times where the work schedule type may designate whether tasks and/or times are planned or actual.  Such work schedule may have assigned tasks indicating detail, where tasks may be assigned to products and may have assigned resources. 
+/// 
+/// As shown in Figure 159, an IfcPermit may be nested into sub-items using IfcRelNests where RelatingObject refers to the enclosing IfcPermit and RelatedObjects contains one or more sub-items.  Nesting use is defined for the following predefined types:
+/// 
+/// (All Types): May contain IfcPermit sub-items.  A permit may be nested to indicate permit ammendments, in order of issue. 
+/// 
+/// Figure 159 — Permit composition
+/// 
+/// Assignment Use Definition 
+/// As shown in Figure 160, an IfcPermit may be assigned to the following entities using relationships as indicated: 
+/// 
+/// IfcActor (IfcRelAssignsToActor): Organization issuing the permit such as a local government agency or security organization. 
+/// 
+/// The IfcPermit may have assignments of its own using the IfcRelAssignsToControl relationship where RelatingControl refers to the IfcPermit and RelatedObjects contains one or more objects of the following types:  
+/// IfcActor: Organization(s) bound to the permit, typically a single contractor.
+/// 
+/// Figure 160 — Permit assignment
+/// 
+/// Approval Use Definition 
+/// Approvals may be associated to indicate the status of acceptance or rejection using the IfcRelAssociatesApproval relationship where RelatingApproval refers to an IfcApproval and RelatedObjects contains the IfcPermit.  Approvals may be split into sub-approvals using IfcApprovalRelationship to track approval status separately for each party where RelatingApproval refers to the higher-level approval and RelatedApprovals contains one or more lower-level approvals.  The hierarchy of approvals implies sequencing such that a higher-level approval is not executed until all of its lower-level approvals have been accepted.

+/// 
+/// The relationship IfcRelSequence is used to indicate
+///   control flow. An IfcProcedure as a successor to an
+///   IfcEvent indicates that the procedure should be
+///   performed in response to the event. An IfcProcedure
+///   as a predecessor to an IfcEvent indicates that the
+///   event should be trigerred following the procedure. As
+///   procedures have arbitrary duration, the
+///   IfcRelSequence.SequenceType attribute has no effect
+///   on an IfcProcedure but still applies to the opposite
+///   end of the relationship if IfcTask is used.
+/// 
+/// Composition use definition
+/// 
+/// IfcProcedure may be contained within an
+///   IfcTask or IfcProcedure using the
+///   IfcRelNests relationship. An IfcProcedure may
+///   in turn nest other IfcProcedure or IfcEvent
+///   entities. Such nesting indicates decomposed level of
+///   detail.
+/// 
+/// Note that a particular type of IfcProcedure is a
+///   caution, warning or other form of advisory note. Typically,
+///   it is anticipated that such a procedure would be assigned
+///   to the specific IfcProcess for which it gives advice
+///   using IfcRelAssignsToProcess.
+/// 
+/// Assignment use definition
+/// 
+/// An IfcProcedure may be assigned to an
+///   IfcWorkCalendar to indicate times when such
+///   procedure may be performed using
+///   IfcRelAssignsToControl; otherwise the effective
+///   calendar is determined by the nearest IfcProcess
+///   ancestor with a calendar assigned. Advisory notes should be
+///   assigned to the specific IfcProcess for which it
+///   gives advice using IfcRelAssignsToProcess.
+/// 
+/// For building operation scenarios, IfcProcedure may
+///   be assigned to a product (IfcElement subtype) using
+///   IfcRelAssignsToProduct to indicate a specific
+///   product occurrence that performs the procedure. For
+///   example, an IfcActuator may have a "Close"
+///   procedure. If the IfcProcedure is defined by an
+///   IfcProcedureType and the IfcProcedureType is
+///   assigned to a product type (using
+///   IfcRelAssignsToProduct), then the
+///   IfcProcedure must be assigned to one or more
+///   occurrences of the specified product type using
+///   IfcRelAssignsToProduct.
+/// 
+/// As shown in Figure 12, IfcProcedure does not restrict anything but
+///   describes specific steps of how something should happen.
+///   While a procedure does control/restrict in the sense of
+///   indicating "this is how the task should be performed" by
+///   nature of describing inner detail, this is not different than
+///   parts of a product indicating "this is how the parts should
+///   be assembled". Consequently, it doesn't restrict the outer

+/// Definition from ISO 6707-1:1989: Area where construction
+/// works are undertaken.
+/// A site is a defined area of land, possibly
+/// covered with water, on which the project construction is to be
+/// completed. A site may be used to erect building(s) or other AEC
+/// products.
+/// A site (IfcSite) may include a definition of the single
+/// geographic reference point for this site (global position using
+/// WGS84 with Longitude, Latitude and Elevation).
+/// The precision is provided up to millionth of a second and it
+/// provides an absolute placement in relation to the real world as
+/// used in exchange with geospational information systems. If
+/// asserted, the Longitude, Latitude and
+/// Elevation establish the point in WGS84 where the point
+/// 0.,0.,0. of the LocalPlacement of IfcSite is
+/// situated.
+/// The geometrical placement of the site, defined by the
+/// IfcLocalPlacement, shall be always relative to the spatial
+/// structure element, in which this site is included, or absolute,
+/// i.e. to the world coordinate system, as established by the
+/// geometric representation context of the project. The world
+/// coordinate system, established at the
+/// IfcProject.RepresentationContexts, may include a definition
+/// of the true north within the XY plane of the world coordinate
+/// system, if provided, it can be obtained at
+/// IfcGeometricRepresentationContext.TrueNorth.
+/// A project may span over several connected or disconnected sites.
+/// Therefore site complex provides for a collection of sites included
+/// in a project. A site can also be decomposed in parts, where each
+/// part defines a site section. This is defined by the composition
+/// type attribute of the supertype IfcSpatialStructureElements
+/// which is interpreted as follow:
+/// 
+/// COMPLEX = site complex
+/// ELEMENT = site
+/// PARTIAL = site section
+/// 
+/// HISTORY  New entity in IFC Release 1.0.
+/// 
+/// Property Set Use Definition
+/// The property sets relating to the IfcSite are defined by
+/// the IfcPropertySet and attached by the
+/// IfcRelDefinesByProperties relationship. It is accessible by
+/// the inverse IsDefinedBy relationship. The following property
+/// set definitions specific to the IfcSite are part of this IFC
+/// release:
+/// 
+/// Pset_SiteCommon: common property set for all
+/// types of site
+/// 
+/// Quantity Use Definition
+/// The quantities relating to the IfcSite are defined by the
+/// IfcElementQuantity and attached by the
+/// IfcRelDefinesByProperties relationship. It is accessible by
+/// the inverse IsDefinedBy relationship. The following base
+/// quantities are defined and should be exchanged with the
+/// IfcElementQuantity.Name = 'BaseQuantities'. Other
+/// quantities, being subjected to local standard of measurement, can
+/// be defined with another string value assigned to Name. In
+/// this case a valid value for MethodOfMeasurement has to be
+/// provided.
+/// 
+/// Qto_SiteBaseQuantities: base quantities for all site
+/// occurrences.
+/// 
+/// Spatial Structure Use Definition
+/// The IfcSite is used to build the spatial structure of a
+/// building (that serves as the primary project breakdown and is
+/// required to be hierarchical). The spatial structure elements are
+/// linked together by using the objectified relationship
+/// IfcRelAggregates. The IfcSite references them by its
+/// inverse relationships:
+/// 
+/// IfcSite.Decomposes -- referencing (IfcProject ||
+/// IfcSite) by IfcRelAggregates.RelatingObject, If it
+/// refers to another instance of IfcSite, the referenced
+/// IfcSite needs to have a different and higher
+/// CompositionType, i.e. COMPLEX (if the other IfcSite
+/// has ELEMENT), or ELEMENT (if the other IfcSite has
+/// PARTIAL).
+/// IfcSite.IsDecomposedBy -- referencing (IfcSite ||
+/// IfcBuilding || IfcSpace) by
+/// IfcRelAggregates.RelatedObjects. If it refers to another
+/// instance of IfcSite, the referenced IfcSite needs to
+/// have a different and lower CompositionType, i.e. ELEMENT (if the
+/// other IfcSite has COMPLEX), or PARTIAL (if the other
+/// IfcSite has ELEMENT).
+/// 
+/// If there are building elements and/or other elements directly
+/// related to the IfcSite (like a fence, or a shear wall), they
+/// are associated with the IfcSite by using the objectified
+/// relationship IfcRelContainedInSpatialStructure. The
+/// IfcIfcSite references them by its inverse relationship:
+/// 
+/// IfcSite.ContainsElements -- referencing any subtype of
+/// IfcProduct (with the exception of other spatial structure
+/// element) by
+/// IfcRelContainedInSpatialStructure.RelatedElements.
+/// 
+/// Figure 51 shows the IfcSite as part of the spatial structure. In addition to the logical spatial structure, also the placement hierarchy is shown. In this example the spatial structure hierarchy and the placement hierarchy are identical.
+/// NOTE Detailed requirements on mandatory element containment and placement structure relationships are given in view definitions and implementer agreements.

+/// The provision of longitude, latitude, height at the IfcSite for georeferencing is provided for upward compatibility reasons. It requires a single instance of IfcSite and WGS84 as coordinate reference system.
+/// For exact georeferencing the new entities IfcCoordinateReferenceSystem and IfcMapConversion should be used.

+/// If the relative placement is not used, the absolute placement
+/// is defined within the world coordinate system. If there is only one

+/// 
+/// Spatial Structure Use Definition
+/// The IfcSpace is used to build the spatial structure of a
+/// building (that serves as the primary project breakdown and is
+/// required to be hierarchical). The spatial structure elements are
+/// linked together by using the objectified relationship
+/// IfcRelAggregates. The IfcSpace references them by its

+/// 
+/// IfcSpace.Decomposes -- referencing (IfcSite ||
+/// IfcBuildingStorey || IfcSpace) by
+/// IfcRelAggregates.RelatingObject, If it refers to another
+/// instance of IfcSpace, the referenced IfcSpace
+/// needs to have a different and higher CompositionType, i.e.
+/// COMPLEX (if the other IfcSpace has ELEMENT), or ELEMENT (if
+/// the other IfcSpace has PARTIAL).
+/// IfcSpace.IsDecomposedBy -- referencing (IfcSpace)
+/// by IfcRelAggregates.RelatedObjects. If it refers to another
+/// instance of IfcSpace, the referenced IfcSpace needs
+/// to have a different and lower CompositionType, i.e. ELEMENT
+/// (if the other IfcSpace has COMPLEX), or PARTIAL (if the
+/// other IfcSpace has ELEMENT).
+/// 
+/// If there are building elements and/or other elements directly
+/// related to the IfcSpace (like most furniture and
+/// distribution elements), they are associated with the
+/// IfcSpace by using the objectified relationship
+/// IfcRelContainedInSpatialStructure. The IfcSpace
+/// references them by its inverse relationship:
+/// 
+/// IfcSpace.ContainsElements -- referencing any subtype of
+/// IfcProduct (with the exception of other spatial structure
+/// element) by
+/// IfcRelContainedInSpatialStructure.RelatedElements.
+///

+/// NOTE In cases of inconsistency between the
+/// geometric representation of the IfcSpace and the combined
+/// geometric representations of the surrounding
+/// IfcRelSpaceBoundary, the geometric representation of the
+/// space should take priority over the geometric representation of the
+/// surrounding space boundaries.
+/// Local Placement
+/// The local placement for IfcSpace is defined in its
+/// supertype IfcProduct. It is defined by the
+/// IfcLocalPlacement, which defines the local coordinate system
+/// that is referenced by all geometric representations.
+/// 
+/// The PlacementRelTo relationship of

+/// space).
+/// If the relative placement is not used, the absolute placement
+/// is defined within the world coordinate system.
+/// 
+/// Geometric Representations
+/// Currently, the use of a 2D 'FootPrint' representation of type

+/// 
+/// Material Use Definition
+/// 
+/// The material of direct instances IfcStructuralCurveMember (in contrast to instances of the subtype IfcStructuralCurveMemberVarying) is defined by IfcMaterialProfileSetUsage and attached by the IfcRelAssociatesMaterial.RelatingMaterial.  It is accessible by the inverse HasAssociations relationship.  Composite profile beams can be represented by refering to several IfcMaterialProfiles within the IfcMaterialProfileSet that is referenced from the IfcMaterialProfileSetUsage.  In case of tapered members, the material profile usage subtype IfcMaterialProfileSetUsageDual is used which specifies IfcMaterialProfileSets separately at the start and the end of the tapered member.
+/// 
+/// The material (IfcMaterial) in each IfcMaterialProfile(Set) is specified minimally by a name which corresponds with an agreed upon standardized structural material designation.  An external reference to the source which specifies the material designation should be provided.  Alternatively, structural material properties may be provided by means of IfcMechanicalMaterialProperties and IfcExtendedMaterialProperties.
+/// 
+/// The profile (IfcProfileDef) in each IfcMaterialProfile(Set) is specified minimally by a name which corresponds with an agreed upon standardized structural profile designation.  An external reference to the source which specifies the profile designation should be provided.  Alternatively or additionally, explicit profile geometry should be provided by using respective subtypes of IfcProfileDef.  Alternatively or additionally, structural profile properties may be provided by means of subtypes of IfcProfileProperties.
+/// 
+/// An IfcProfileDef is a two-dimensional geometric object with a xp,yp coordinate system.  The profile is inserted into the curve member model thus that the origin of xp,yp is located at the member's reference curve and that xp,yp are parallel with and directed like the local y,z.
+/// 
+/// NOTE   Due to convention in structural mechanics, axis names of IfcStructuralCurveMember differ from axis names of building elements like IfcBeamStandardCase:  The extrusion axis of IfcStructuralCurveMember is called x while the extrusion axis of IfcBeamStandardCase is called z.  Hence x,y,z of IfcStructuralCurveMember correspond with z,x,y of IfcBeamStandardCase.
+/// 
+/// If the profile is meant to be inserted centrically in terms of structural section properties, it is necessary that the origin of xp,yp is identical with the geometric centroid of the profile (commonly also called centre of gravity).  If subtypes of IfcParameterizedProfileDef are used which are only singly symmetric or are asymmetric, an explicit translation by IfcParameterizedProfileDef.Position.Location is required then.
+/// 
+/// If the profile is inserted at its geometric centroid, IfcMaterialProfileSetUsage.CardinalPoint shall be set to 10.
+/// 
+/// Otherwise, the profile is inserted eccentrically and a different cardinal point should be set accordingly.
+/// 
+/// NOTE   Another eccentricity model is available independently of eccentric profile specification:  The reference curve of the member may be located eccentrically relative to the reference points of the connected IfcStructuralPointConnections.

+/// An IfcSubContractResource can be used in cost estimating and work planning with or without specifying the subcontractor and contract agreement. 
+/// The purpose of an IfcSubContractResource is to indicate work of a particular type that is that is to be engaged through the use of a sub-contract. It's aim is to identify the description of the sub-contract work required. It can be used to identify the generic type of sub-contract resource that is required for a purpose without having to be specific about the actor (person or organization) providing the resource occurrence. It may be particularly useful when creating an overall plan for a process or processes. For instance, within maintenance or work planning there may be a known task that needs to be done which is planned to require an 'insulation specialist'. 
+/// A subcontract resource may be described at various stages and levels of detail through its assignments:

+/// Definition from IAI: A surface feature is a modification at (onto, or into) of the surface of an element.  Parts of the surface of the entire surface may be affected.  The volume and mass of the element may be increased, remain unchanged, or be decreased by the surface feature, depending on manufacturing technology.
+/// 
+/// The standard use of instances of IfcSurfaceFeature is as a part of element type objects (instances of subtypes of IfcElementType).  The part–whole relationship is established by an aggregation relationship object, expressing the decomposition of an element type into one or more additive elements (element parts) and zero or more feature elements.
+/// 
+/// HISTORY New type in IFC 2x4.

+/// Containment Use Definition:
+/// 
+/// Surface features shall have no spatial containment relationship to the spatial structure since they are dependent on element types without spatial containment relationships or on an element occurrence with own spatial containment relationship.

+/// 
+/// Geometry use definition:
+/// 
+/// The geometric representation of IfcSurfaceFeatureElement is given by the IfcProductDefinitionShape, allowing multiple geometric representation.
+/// 
+/// Local Placement
+/// 
+/// The local placement for IfcSurfaceFeatureElement is defined in its supertype IfcProduct. It is defined by the IfcLocalPlacement, which defines the local coordinate system that is referenced by all geometric representations.
+/// 
+/// In case of features which are part of an element type, absolute placement into the type object's implied coordinate system shall be used.
+///   In case of features which are voiding an element occurrence, the PlacementRelTo relationship of IfcLocalPlacement shall point to the local placement of the respective element.
+/// 
+/// Shape representation
+/// 
+/// Different shape representations may be used, depending on the nature of the feature and information requirements:
+/// 
+/// Symbolic representation, such as the two-dimensional bounding box of a tag.
+///   A geometric set representing the geometric items of a mark.
+///   Surface representations of treated parts of the lement surface by means of IfcShellBasedSurfaceModel.  The faces within the surface model may be included into a B-Rep model within a representation map of the parent element type.

+/// 
+/// Geometry Use Definitions:
+/// The geometric representation of IfcTransportElement is
+/// given by the IfcProductDefinitionShape, allowing multiple
+/// geometric representation.
+/// Local Placement
+/// The local placement for IfcTransportElement is defined

+/// Definition from ISO/CD 10303-42:1992:
+/// A trimmed curve is a bounded curve which is created by taking a selected
+/// portion, between two identified points, of the associated basis curve.
+/// The basis curve itself is unaltered and more than one trimmed curve may
+/// reference the same basis curve. Trimming points for the curve may be
+/// identified by:
+///   parametric value  geometric
+/// position  both of the above 
+/// At least one of these shall be specified at each
+/// end of the
+/// curve. The SenseAgreement makes it possible to
+/// unambiguously define any segment of a closed curve such as a circle.
+/// The combinations of sense and ordered end points make it possible to
+/// define four distinct directed segments connecting two different points
+/// on a circle or other closed curve. For this purpose cyclic properties
+/// of the parameter range are assumed; for example, 370 degrees is
+/// equivalent to 10 degrees. 
+/// The IfcTrimmedCurve has a parameterization
+/// which is inherited from the particular basis curve reference. More
+/// precisely the parameter s of the trimmed curve is derived from the
+/// parameter of the basis curve as follows: 
+///   if SenseAgreement is TRUE: s
+/// = t - t1  if SenseAgreement
+/// is FALSE: s
+/// = t2 - t 
+/// In the above equations t1 is
+/// the value
+/// given by Trim1 or the parameter value corresponding
+/// to point 1 and t2 is the value given by Trim2
+/// or the parameter value corresponding to point 2. The resultant IfcTrimmedCurve
+/// has a parameter ranging from 0 at the first trimming point to |t2
+/// - t1| at the second trimming point. 
+///   NOTE In case
+/// of a closed curve,
+/// it may be necessary to increment t1 or t2 by the parametric length for
+/// consistency with the sense flag.
+/// 
+/// NOTE Corresponding ISO 10303 entity: trimmed_curve; As a further IFC restriction, an IfcTrimmedCurve should only trim a IfcLine or IfcConic. Please refer to ISO/IS 10303-42:1994, p. 54 for the final definition of the formal standard.
+/// 
+/// HISTORY New class in IFC Release 1.0
+/// 
+/// Informal Propositions:
+///   Where both the parameter value and the Cartesian
+/// point
+/// exist for Trim1 and Trim2 they
+/// shall be consistent. (i.e., the BasisCurve
+/// evaluated at the parameter value shall coincide with the specified
+/// point). When a Cartesian point is specified by Trim1
+/// or by Trim2 it shall lie on the BasisCurve.
+/// Except the case of a closed BasisCurve
+/// where both parameter 1 and parameter 2 exist, they shall be consistent
+/// with the sense flag, i.e., (sense = parameter 1 < parameter 2). Or, for every open curve where both
+/// parameter 1 and parameter 2 exist, they shall be consistent with the SenseAgreement,
+/// i.e., SenseAgreement = (parameter 1 <
+/// parameter 2). If both parameter 1
+/// and parameter 2 exist, then parameter 1
+/// <> parameter 2. For a
+/// closed base curve, e.g. IfcCircle or IfcEllipse,
+/// this also applies to the cyclic properties, as 360' is equal to 0',
+/// parameter 1 = 360' and parameter 2 = 0' are treated as being equal and
+/// therefore violating this proposition. When
+/// a parameter value is specified by Trim1
+/// or Trim2 it shall lie within the parametric range
+/// of the BasisCurve.
+/// Additional illustration from IAI:
+///   The
+/// figure above shows the four arcs (dashed blue and
+/// green lines with arrow showing different orientations) that can be
+/// defined by the same BasisCurve (of type IfcCircle)
+/// and the same trimming points (given by Cartesian points and parameter
+/// values) by using different assignments to Trim1 and
+/// Trim2 and SenseAgreement.  
+/// Note: Since the BasisCurve is closed (type IfcCircle),
+/// the exception of the informal proposition IP3 applies, i.e. the sense
+/// flag is not
+/// required to be consistent with the parameter values of Trim1
+/// and Trim1, so the rule (sense = parameter 1
+/// < parameter 2) may not be fulfilled.

+/// An IfcWorkCalendar defines working and non-working time periods for tasks and resources. It enables to define both specific time periods, such as from 7:00 till 12:00 on 25th August 2009, as well as repetitive time periods based on frequently used recurrence patterns, such as each Monday from 7:00 till 12:00 between 1st March 2009 and 31st December 2009.
+/// 
+/// HISTORY  New entity in IFC2x4.
+/// 
+/// A work calendar is a subtype of IfcControl and thus inherits the feature for controlling other objects through IfcRelAssignsToControl, which is used to define a work calendar for tasks (IfcTask) and resources (IfcResource). It also inherits a name and description attribute, whereas a name shall be given and a description may be given as an indication of its content and usage.
+/// 
+/// The definition of time periods can be derived from a base calendar and/or modified/defined by a set of working times and non-working exception times. All time periods defined by IfcWorkCalendar.ExceptionTimes override the time periods inherited from the base calendar (base calendar is defined as the next applicable calendar for the task or resource). Thus, exception times replace the working times from the base calendar.
+/// 
+/// The base calendar of a work calendar is defined by IfcRelAssignsToControl, where IfcRelAssignsToControl.RelatingControl is linked with the base calendar and IfcRelAssignsToControl.RelatedObjects is linked with work calendars that are derived from the base calendar. Although not restricted by the IfcRelAssignsToControl relationship it is only allowed to have one base calendar.
+/// 
+/// Figure 17 shows the definition of a work calendar, which is defined by a set of work times and exception times. The work times are defined as recurring patterns with optional boundaries (applying from and/or to a specific date). The shown example defines a simple work calendar with working times Monday to Thursday 8:00 to 12:00 and 13:00 to 17:00, Friday 8:00 to 14:00 and as exception every 1st Monday in a month the work starts one hour later - i.e. the working time on every 1st Monday in a month is overriden to be 9:00 to 12:00 and 13:00 to 17:00. Both the working time and the exception time is valid for the period of 01.09.2010 till 30.08.2011.

+/// 
+/// CHANGE IFC2x4  Corrected assignment of resources to work control in documentation. Assignment of tasks to work control updated based on changes of task time definitions and the introduction of a summary task. Identifier has been renamed (now Identification) and promoted to supertype IfcControl
+/// 
+/// A work control may have resources assigned to it, this is
+///   handled by the IfcRelAssignsToControl relationship.
+///   A work control should also define a context that gives

+/// 
+/// From IFC2x4 onwards the assignment of tasks to the work
+///   control is handled by the IfcRelAssignsToControl
+///   relationship. IfcRelAssignsTasks as used in previous
+///   IFC releases has been deleted and can not be used any
+///   longer. Another change in IFC2x4 is that it is not
+///   necessary to assign each task to a work control as it is
+///   regarded to be sufficient if the summary task (root task in
+///   the task hierarchy defined through IfcRelNests
+///   relationships) is assigned to a work control.

+/// hierarchical (in contrary to the spatial structure of a project -
+/// see IfcSpatialStructureElement), i.e. one individual
+/// IfcSpace may be associated with zero, one, or several
+/// IfcZone's. IfcSpace's are grouped into an
+/// IfcZone by using the objectified relationship
+/// IfcRelAssignsToGroup as specified at the supertype
+/// IfcGroup.
+/// NOTE Certain use cases may restrict the
+/// freedom of non hierarchical relationships. In some building
+/// service use cases the zone denotes aview based delimited volume
+/// for the purpose of analysis and calculation. This type of zone
+/// cannot overlap with respect to that analysis, but may overlap
+/// otherwise.
+/// An IfcZone is a spatial system under which individual
+/// IfcSpace's (and other IfcZone's) are grouped. In
+/// contrary to the IfcSpatialZone entity, IfcZone is a
+/// mere grouping, it can not define an own geometric representation
+/// and placement. Therefore it cannot be used for spatial zones
+/// having a different shape and size compared to the shape and size
+/// of aggregated spaces.
+/// NOTE The IfcZone is regarded as the
+/// spatial system (as compared to the building service, electrical,
+/// or analytical system), the name remains IfcZone for
+/// compatibility reasons, instead of using a proper naming
+/// convention, like IfcSpatialSystem.
+/// NOTE One of the purposes of a zone is to
+/// define a fire compartmentation. In this case it defines the
+/// geometric information about the fire compartment (through the
+/// contained spaces) and information, whether this compartment is
+/// ventilated or sprinkler protected. In addition the fire risk code
+/// and the hazard type can be added, the coding is normally defined
+/// within a national fire regulation. All that information is
+/// available within the relevant property sets. Again, if an
+/// independent shape has to be provided to the fire compartment,
+/// then the entity IfcSpatialZone shall be
+/// used.
+/// RECOMMENDATION In case of a zone denoting a
+/// (fire) compartment, the following types should be used, if
+/// applicable, as values of the ObjectType attribute:
+/// 
+/// FireCompartment - a zone of spaces, collected to
+/// represent a single fire compartment.
+/// ElevatorShaft - a collection of spaces within an
+/// elevator, potentially going through many storeys.
+/// RisingDuct
+/// RunningDuct
+/// 
+/// Additional classifications of the IfcZone, as provided
+/// by a national classification system, can be assigned by using the
+/// IfcRelAssociatesClassification relationship, accessible
+/// via the inverse attribute HasAssociations. The
+/// IfcZone can be assigned to a spatial structure element, it
+/// refers to, e.g. to a particular IfcBuildingStorey by using

+/// An asset is a uniquely identifiable grouping of elements acting as a single entity that has a financial value or that can be operated on as a single unit.

+/// An asset is generally the level of granularity at which maintenance operations are undertaken. An asset is a group that can contain one or more elements. Whilst the financial value of a component or element can be defined, financial value is also defined for accounting purposes at the level of the asset.  There are a number of actors that can be associated with an asset, each actor having a role. Actors within the scope of the project are indicated using the IfcRelAssignsToActor relationship in which case roles should be defined through the IfcActorRole class; otherwise principal actors are identified as attributes of the class. In the existence of both, direct attributes take precedence.  There are a number of costs that can be associated with an asset, each cost having a role.

+/// Definition from ISO 6707-1:1989: Structural member of

+/// <An IfcColumn is a vertical
+/// structural member which often is aligned with a structural grid
+/// intersection. It represents a vertical, or nearly vertical,
+/// structural member that transmits, through compression, the weight
+/// of the structure above to other structural elements below. It
+/// represents such a member from an architectural point of view. It
+/// is not required to be load bearing.
+/// NOTE The representation of a column in a

+/// 
+/// NOTE For any longitudial structural member, not
+/// constrained to be predominately horizontal nor vertical, or where
+/// this semantic information is irrelevant, the entity
+/// IfcMember exists.
+/// The IFC specification provides two entities for column
+/// occurrences:
+/// 
+/// IfcColumnStandardCase used for all occurrences of
+/// columns, tthat have a profile defined that is swept along a
+/// directrix. The profile might be changed uniformly by a taper
+/// definition along the directrix. The profile parameter and its
+/// cardinal point of insertion can be fully described by the
+/// IfcMaterialProfileSetUsage. These beams are always
+/// represented geometricly by an 'Axis' and a 'SweptSolid' or
+/// 'AdvancedSweptSolid' shape representation (or by a 'Clipping'
+/// geometry based on the swept solid), if a 3D geometric
+/// representation is assigned. In addition they have to have a
+/// corresponding IfcMaterialProfileSetUsage assigned.
+/// NOTE View definitions and implementer
+/// agreements may further constrain the applicable geometry types,
+/// e.g. by excluding tapering from an IfcColumnStandardCase
+/// implementation.
+/// 
+/// IfcColumn used for all other occurrences of columns,
+/// particularly for columns with changing profile sizes along the
+/// extrusion, or columns defined by non-linear extrusion, or columns
+/// having only 'Brep', or 'SurfaceModel' geometry.
+/// 
+/// HISTORY New entity in IFC Release 1.0
+/// 
+/// Type Use Definition
+/// IfcColumn defines the occuurence of any column, common
+/// information about column types (or styles) is handled by
+/// IfcColumnType. The IfcColumnType (if present) may
+/// establish the commontype name, usage (or predefined) type,

+/// shape representations (using IfcRepresentationMap). The
+/// IfcColumnType is attached using the
+/// IfcRelDefinedByType.RelatingType objectified relationship
+/// and is accessible by the inverse IsTypedBy attribute.
+/// If no IfcColumnType is attached(i.e. if only
+/// occurrence information is given) the PredefinedType should
+/// be provided. If set to .USERDEFINED. a user defined value can be
+/// provided by the ObjectType attribute.
+/// Material Use Definition
+/// The material of the IfcColumn is defined by the
+/// IfcMaterialProfileSet or as fallback by IfcMaterial
+/// and attached by the
+/// IfcRelAssociatesMaterial.RelatingMaterial. It is
+/// accessible by the inverse HasAssociations
+/// relationship.
+/// Note: It is illegal to assign an
+/// IfcMaterialProfileSetUsage to an IfcColumn. Only
+/// the subtype IfcColumnStandardCase supports this
+/// concept.
+/// Material information can also be given at the
+/// IfcColumnType, defining the common attribute data for all
+/// occurrences of the same type.It is then accessible by the
+/// inverse IsTypedBy
+/// relationship pointing to
+/// IfcColumnType.HasAssociations and via
+/// IfcRelAssociatesMaterial.RelatingMaterial to
+/// IfcMaterialProfileSet or IfcMaterial. If both are
+/// given, then the material directly assigned to IfcColumn
+/// overrides the material assigned to IfcColumnType.

+/// 
+/// Containment Use Definition
+/// The IfcColumn, as any subtype of

+/// scenarios mandatory) relationship is the hierachical spatial
+/// containment, the second (optional) relationship is the

+/// 
+/// The IfcColumn, is places within the project spatial
+/// hierarchy using the objectified relationship
+/// IfcRelContainedInSpatialStructure, refering to it by its
+/// inverse attribute SELF\IfcElement.ContainedInStructure.
+/// Subtypes ofIfcSpatialStructureElement are valid spatial
+/// containers, with IfcBuildingStorey being the default
+/// container.
+/// The IfcColumn, may be aggregated into an element
+/// assembly using the objectified relationship
+/// IfcRelAggregates, refering to it by its inverse attribute
+/// SELF\IfcObjectDefinition.Decomposes. Any subtype of
+/// IfcElement can be an element assembly, with
+/// IfcElementAssembly as a special focus subtype. In this
+/// case it should not be additionally contained in the project
+/// spatial hierarchy,
+/// i.e.SELF\IfcElement.ContainedInStructure should be
+/// NIL.
+/// 
+/// Geometry Use Definition
+/// The geometric representation of IfcColumn is given by
+/// the IfcProductDefinitionShape, allowing multiple geometric
+/// representations. Included are:
+/// Local Placement
+/// The local placement for IfcColumn is defined in its
+/// supertype IfcProduct. It is defined by the
+/// IfcLocalPlacement, which defines the local coordinate
+/// system that is referenced by all geometric representations.
+/// 
+/// The PlacementRelTo relationship of
+/// IfcLocalPlacement shall point (if given) to the local
+/// placement of the same IfcSpatialStructureElement, which is
+/// used in the ContainedInStructure inverse attribute, or to
+/// a spatial structure element at a higher level, referenced by
+/// that.
+/// If the relative placement is not used, the absolute placement
+/// is defined within the world coordinate system.

+/// HISTORY: New Entity in IFC Release 2.0. Renamed from IfcProductResource in IFC 2x.  Base type and documentation extended in IFC2x4.
+/// 
+/// Occurrences of IfcConstructionProductResource are usage of products to assist the process of construction. More specifically, they are usage of products that result from some construction processes and that are then used as resources to facilitate further construction. For instance, formworks can be instantiated as products resulting from the process &#145;constructing formwork&#146;. However, they are used as resources in the process &#145;pouring concrete&#146; in a later stage of the project. IfcConstructionProductResource occurrences  are explicitly instances of IfcProduct and may be drawn from various of the subtypes, for instance IfcElementComponent, IfcElementAssembly, IfcProxy (for particular cases where more precise usage details are not available).  The product that is used as a construction resource is referenced using the IfcRelAssignsToResource.RelatedObjects relationship. 
+/// 
+/// Use definitions for composition, assignment, constraints, time series, and baselines are described at the base type IfcConstructionResource.
+/// 
+/// Type use definition
+/// IfcConstructionProductResource defines the occurrence of any product resource; common information about product resource types is handled by IfcConstructionProductResourceType.  The IfcConstructionProductResourceType (if present) may establish the common type name, common properties, and common productivities for various task types using IfcRelAssignsToProcess.  The IfcConstructionProductResourceType is attached using the IfcRelDefinesByType.RelatingType objectified relationship and is accessible by the inverse IsTypedBy attribute.
+/// 
+/// Assignment use definition
+/// In addition to assignments specified at the base class IfcConstructionResource, a construction product resource may have assignments of its own using IfcRelAssignsToResource where RelatingResource refers to the IfcConstructionProductResource and RelatedObjects contains one or more IfcProduct subtypes as shown in Figure 185.  Such relationship indicates the products used as input for the resource.  Such products are not contained within a building structure but are referenced within a construction spatial zone, specifically IfcSpatialZone with PredefinedType=CONSTRUCTION, which is aggregated within the IfcProject.  There may be multiple chains of production such that the assigned products may have their own task and resource assignments.

+/// Definition from ISO 6707-1:1989: term used: Finishing -

+/// A covering is an element which
+/// covers some part of another element and is fully dependent on
+/// that other element. The IfcCovering defines the occurrence
+/// of a covering type, that (if given) is expressed by the
+/// IfcCoveringType. Examples of coverings include wall
+/// claddings, floorings and suspended ceilings. Coverings are
+/// elements with relationships to the covered element and the space
+/// on the other side, they may contain openings, assigned by
+/// IfcRelVoidsElement, material information, assigned by
+/// IfcRelAssociatesMaterial, and others.
+/// NOTE A more basic information about claddings,
+/// floorings, and ceilings of a space can be attached to
+/// IfcSpace's using the Pset_SpaceCommon properties. Then
+/// only a name can be provided and the covering quantities would be
+/// interpreted from the space quantities.
+/// Coverings can be assigned to
+/// 
+/// a space represented by IfcSpace
+/// 
+/// using the inverse relationship CoversSpaces pointing
+/// to IfcRelCoversSpaces. The space is then accessible via
+/// IfcRelCoversSpaces.RelatedSpace. It defines to which space
+/// a covering is facing towards.
+/// 
+/// NOTE The mere containment relationship between an
+/// IfcCovering and an IfcSpace is
+/// created by using
+/// IfcRelContainedInSpatialStructure
+/// 
+/// a space boundary represented by IfcRelSpaceBoundary
+/// 
+/// using the inverse relationship ProvidesBoundaries
+/// pointing to IfcRelSpaceBoundary. The space is then

+/// 
+/// The following guideline shall apply:
+/// 
+/// (default) if the space has coverings that may not have an own
+/// shape representation and no defined relationships to the building
+/// elements they cover, then the IfcCovering shall be
+/// assigned to IfcSpace using the IfcRelCoversSpaces
+/// relationship,
+/// if the space has coverings that have an own shape
+/// representation and the space has defined space boundaries, then
+/// the covering, which relates to that space, may be assigned to the

+/// as an aggregate, the geometric representation is the sum of the
+/// representations of the components within the aggregate.
+/// Local placement
+/// The local placement for IfcCurtainWall is defined in
+/// its supertype IfcProduct. It is defined by the
+/// IfcLocalPlacement, which defines the local coordinate
+/// system that is referenced by all geometric representations.
+/// 
+/// The PlacementRelTo relationship of
+/// IfcLocalPlacement shall point (if given) to the same
+/// IfcSpatialStructureElement that is used in the
+/// ContainedInStructure inverse attribute or to a referenced
+/// spatial structure element at a higher level.
+/// If the relative placement is not used, the absolute placement
+/// is defined within the world coordinate system.
+/// 
+/// If the IfcCurtainWall establishes an aggregate, then
+/// all contained elements (defined by the IsDecomposedBy
+/// inverse attribute) shall be placed relative to the
+/// IfcCurtainWall.ObjectPlacement.
+/// Geometric Representation
+/// The geometric representation of IfcCurtainWall is
+/// defined using the following multiple shape representations for
+/// its definition:
+/// 
+/// Axis: A two-dimensional open curve (for restrictions see
+/// below) defining the axis for the curtain wall.
+/// 
+/// This is an optional representation for curtain walls.
+/// 
+/// Body: A surface model or boundary representation model
+/// representation defining the 3D shape of the curtain wall.
+/// 
+/// If the IfcCurtainWall has components (referenced by
+/// SELF\IfcObject.IsDecomposedBy) then no independent shape
+/// representation with RepresentationType = 'Body' shall be
+/// defined. The body of IfcCurtainWall is then geometrically
+/// represented by the shape representation of its components. The
+/// components are accessed via
+/// SELF\IfcObject.IsDecomposedBy[1].RelatedObjects.
+/// 
+/// If the IfcCurtainWall has no components defined (empty
+/// set of SELF\IfcObject.IsDecomposedBy) then the
+/// IfcCurtainWall may be represented by an shape
+/// representation with the RepresentationIdentifier =
+/// 'Body'.
+/// 
+/// Axis Representation
+/// The axis geometric representation of IfcCurtainWall is
+/// defined using the 'Axis' representation. The following attribute
+/// values for the IfcShapeRepresentation holding this
+/// geometric representation shall be used:
+/// 
+/// RepresentationIdentifier : 'Axis'

+/// 
+/// The following additional constraints apply to the 'Axis'
+/// representation:
+/// 
+/// Axis : IfcPolyline having two Points, or
+/// IfcTrimmedCurve with BasisCurve of Type

+/// HISTORY New entity in
+/// IFC Release 1.5.
+/// IFC2x4 CHANGE The entity is marked
+/// as deprecated for instantiation - will be made ABSTRACT after
+/// IFC2x4.
+/// Relationship Use Definition
+/// 
+/// Ports - information, whether the distribution element has
+/// ports for system connections
+/// 
+/// objectified relationship:
+/// IfcRelConnectsPortToElement
+/// object referenced by relationship: IfcPort
+/// inverse attribute: HasPorts
+/// 
+/// Type Use Definition
+/// The IfcDistributionElement defines the occurrence of
+/// any HVAC, electrical, sanitary or other element within a
+/// distribution system. Common information about distribution
+/// element types (or styles) is handled by subtypes of
+/// IfcDistributionElementType. The
+/// IfcDistributionElementType (if present) may establish the
+/// common type name, usage (or predefined) type, common material,
+/// common set of properties and common shape representations (using
+/// IfcRepresentationMap). The
+/// IfcDistributionElementType is attached using the
+/// IfcRelDefinedByType.RelatingType objectified relationship
+/// and is accessible by the inverse IsDefinedBy
+/// attribute.
+/// The assignment of types to distribution element occurrences is
+/// vital for providing the additional meaning, or ontology, of the
+/// distribution element. Many specialized type are defined in other
+/// schemas of the IFC specification.
+/// Quantity Use Definition
+/// The quantities relating to the IfcDistributionElement
+/// are defined by the IfcElementQuantity and attached by the
+/// IfcRelDefinesByProperties. A detailed specification for
+/// individual quantities is introduced at the level of subtypes of
+/// IfcDistributionElement.
+/// Containment Use Definition
+/// The IfcDistributionElement may participate in two
+/// different containment relationships. The first (and in most
+/// implementation scenarios mandatory) relationship is the
+/// hierachical spatial containment, the second (optional)
+/// relationship is the aggregation within anelement assembly.
+/// 
+/// The IfcDistributionElement is places within the
+/// project spatial hierarchy using the objectified relationship
+/// IfcRelContainedInSpatialStructure, referring to it by its
+/// inverse attribute SELF\IfcElement.ContainedInStructure.
+/// Subtypes ofIfcSpatialStructureElement are valid spatial
+/// containers, with IfcSpace being the default
+/// container.
+/// The IfcDistributionElement may be aggregated into an
+/// element assembly using the objectified relationship
+/// IfcRelAggregates, referring to it by its inverse attribute
+/// SELF\IfcObjectDefinition.Decomposes. Any subtype of
+/// IfcElement can be an element assembly, with
+/// IfcElementAssembly as a special focus subtype. In this
+/// case it should not be additionally contained in the project
+/// spatial hierarchy,
+/// i.e.SELF\IfcElement.ContainedInStructure should be
+/// NIL.
+/// 
+/// Geometry Use Definitions
+/// The geometric representation of IfcDistributionElement
+/// is given by the IfcProductDefinitionShape, allowing
+/// multiple geometric representation.
+/// Local Placement
+/// The local placement for IfcDistributionElement is
+/// defined in its supertype IfcProduct. It is defined by the
+/// IfcLocalPlacement, which defines the local coordinate
+/// system that is referenced by all geometric representations.
+/// 
+/// The PlacementRelTo relationship of
+/// IfcLocalPlacement shall point (if given) to the local
+/// placement of the same IfcSpatialStructureElement , which
+/// is used in the ContainedInStructure inverse attribute, or
+/// to a spatial structure element at a higher level, referenced by
+/// that.
+/// If the relative placement is not used, the absolute placement
+/// is defined within the world coordinate system.
+/// 
+/// Geometric Representations
+/// The geometric representation of IfcDistributionElement
+/// is defined using different geometric representation types for the
+/// various subtypes. Only general recommendations are given at the
+/// level of the supertype, further constraints are defined at the
+/// level of its subtypes.
+/// 
+/// all occurrences of IfcDistributionElement (and its
+/// subtypes) should (whenever possible) share a representation map
+/// established by the assigned type. The geometric representation of
+/// the occurrence is then an IfcMappedItem. The
+/// IfcShapeRepresentation has:
+/// 
+/// RepresentationIdentifier : 'Body'
+/// RepresentationType : 'MappedRepresentation'
+/// 
+/// The shared geometric representation of the distribution
+/// element type (or in some cases of the distribution element)
+/// should follow (if applicable) the the following guidelines:
+/// 
+/// all fixtures (all non distribution flow elements, i.e.
+/// everything which is not a duct, a pipe, a cable, or a cable
+/// carrier) should be defined by an b-rep geometry. This includes
+/// also the complex flow fitting elements (e.g. Y branch or T
+/// branch) or distribution flow elements with size changes (e.g.
+/// reducer). The IfcShapeRepresentation has:
+/// 
+/// RepresentationIdentifier : 'Body'
+/// RepresentationType : 'Brep'
+/// 
+/// if the geometric model consistency of a b-rep shape
+/// representation can not be guaranteed (arcwise connected volume
+/// bounded by faces, each being connected, oriented, finite, closed
+/// 2-manifold), a surface representation based on open shells should
+/// be used. The IfcShapeRepresentation then has:
+/// 
+/// RepresentationIdentifier : 'Body'
+/// RepresentationType : 'SurfaceModel'
+/// 
+/// all "simple" distribution flow elements (general ducts and
+/// pipes) are defined by sweep geometry. The
+/// IfcShapeRepresentation has:
+/// 
+/// RepresentationIdentifier : 'Body'
+/// RepresentationType : 'SweptSolid'
+/// 
+/// an additional representation type for all "simple"
+/// distribution flow elements (general ducts and pipes) is the
+/// ability to have a simple line based representation. The
+/// IfcShapeRepresentation has:
+/// 
+/// RepresentationIdentifier : 'FootPrint'
+/// RepresentationType : 'GeometricCurveSet'
+/// 
+/// if only the analytical shape is required for which the exact
+/// interpolation between the cross sections is not required, a
+/// sectioned spine can be used.
+/// 
+/// RepresentationIdentifier : 'Body'
+/// RepresentationType : 'SectionedSpine'

If the IfcDistributionFlowElementType has ports or aggregated elements, such objects are reflected at the IfcDistributionFlowElement occurrence using the IfcRelDefinesByObject relationship.  Direct instantiation of IfcDistributionFlowElement with IfcObject.ObjectType asserted provides the meaning of a distribution flow element proxy.
+/// 
+/// Property Set Use Definition

+/// IfcElement (IfcRelInterferesElements) : Indicates interference with another element and precedence, such as a pipe going through a wall.
+/// IfcOpening (IfcRelFillsElement) : Indicates embedding an element within another element (implying a cutout), such as an air terminal or junction box embedded within a wall.
+/// IfcDistributionPort (IfcRelConnectsPortToElement) : Indicates ports on the element which may be connected to other elements for flow distribution of solids, liquids, gas, or electricity.  Standard port names, types, and directions are defined at subtypes.

+/// 
+/// For all representations, if a IfcDistributionFlowElement occurrence is defined by a IfcDistributionFlowElementType having a representation of the same identifier, then 'MappedRepresentation' should be used at the occurrence unless overridden.

+/// HISTORY New entity in IFC 2x4.
+/// 
+/// The group IfcDistributionSystem
+/// defines the occurrence of a specialized system for use within the context of building services.
+/// 
+/// NOTE: For electrical power systems, IfcElectricalCircuit has been used for low-voltage (12-1000 V) power systems and has been deprecated in IFC2x4; IfcDistributionSystem with PredefinedType 'ELECTRICAL' should now be used instead.
+/// 
+/// Important functionalities for the description of a distribution system are derived from existing IFC entities:
+/// 
+/// From IfcSystem it inherits the ability to couple the distribution system via IfcRelServicesBuildings to one or more IfcSpatialElement subtypes as necessary.
+/// 
+/// From IfcGroup it inherits the inverse attribute IsGroupedBy, pointing to the relationship class IfcRelAssignsToGroup. This allows to group distribution elements (instances of IfcDistributionElement subtypes), and in special cases ports directly (instances of IfcDistributionPort).
+/// 
+/// From IfcObject it inherits the inverse attribute IsDecomposedBy pointing to the relationship class IfcRelAggregates. It provides the hierarchy between the separate (partial) distribution systems.  For example, an electrical main circuit may be aggregated into branch circuits.
+/// 
+/// Property Set Use Definition:
+/// 
+/// The property sets relating to this entity are defined by the IfcPropertySet and attached by the IfcRelDefinesByProperties relationship. It is accessible by the inverse IsDefinedBy relationship.  The following property set definitions specific to this entity are part of this IFC release:
+/// 
+/// Pset_DistributionSystemCommon: common property set for distribution system occurrences
+/// 
+/// Pset_DistributionSystemTypeElectrical: property set for electrical systems
+/// 
+/// Pset_DistributionSystemTypeVentilation: property set for ventilation systems
+/// 
+/// Assignment Use Definition:
+/// 
+/// For the most common case of an IfcDistributionElement subtype containing ports of a particular PredefinedType that all belong to the same distribution system, the IfcDistributionElement is assigned to the IfcDistributionSystem via the IfcRelAssignsToGroup relationship, where IfcDistributionPort's are implied as part of the corresponding system based on their PredefinedType.  An IfcDistributionElement may belong to multiple systems, however only one IfcDistributionSystem of a particular PredefinedType.
+/// 
+/// For rare cases where an IfcDistributionElement subtype contains ports of the same PredefinedType yet different ports belong to different systems, alternatively each IfcDistributionPort may be directly assigned to a single IfcDistributionSystem via the IfcRelAssignsToGroup relationship, where the PredefinedType must match.  Such assignment indicates that the IfcDistributionSystem assigned from the IfcDistributionPort overrides any such system of the same PredefinedType assigned from the containing IfcDistributionElement, if any.
+/// 
+/// Additionally, an IfcDistributionSystem may in turn be assigned to an IfcDistributionPort indicating the host or origination of the system using IfcRelAssignsToProduct.
+/// 
+/// EXAMPLE: A gas-powered hot water heater may have three ports: GAS, DOMESTICCOLDWATER, and DOMESTICHOTWATER.  The heater is a member of two systems (GAS and DOMESTICCOLDWATER), and hosts one system (DOMESTICHOTWATER) at the corresponding port.

+/// Definition from ISO 6707-1:1989: Construction for
+/// closing an opening, intended primarily for access with hinged,
+/// pivoted or sliding operation.
+/// The door is a building element
+/// that is predominately used to provide controlled access for
+/// people and goods. It includes constructions with hinged, pivoted,
+/// sliding, and additionally revolving and folding operations. A
+/// door consists of a lining and one or several panels.
+/// The IfcDoor defines a particular occurrence of a door
+/// inserted in the spatial context of a project. A door can:
+/// 
+/// be inserted as a filler in an opening using the
+/// IfcRelFillsElement relationship, then the IfcDoor
+/// has an inverse attribute FillsVoids provided,
+/// 
+/// NOTE View definitions or
+/// implementer agreements may restrict the relationship to only
+/// include one window (or door) into one opening.
+/// 
+/// be part of an element assembly, in general an
+/// IfcCurtainWall, using the IfcRelAggregates
+/// relationship, then the inverse attribute Decomposes is
+/// provided.
+/// or be a "free standing" door, then the IfcDoor has no
+/// inverse attributes FillsVoids or Decomposes
+/// provided.
+/// 
+/// The IFC specification provides two entities for door
+/// occurrences:
+/// 
+/// IfcDoorStandardCase used for all occurrences of doors,
+/// that have a 'Profile' shape representation defined to which a set
+/// of shape parameters for lining and framing properties apply.
+/// Additionally it requires the provision of an IfcDoorType
+/// that references one IfcDoorLiningProperties and on to many
+/// IfcDoorPanelProperties.
+/// 
+/// NOTE see
+/// IfcDoorStandardCase for all specific constraints imposed
+/// by this subtype.
+/// 
+/// IfcDoor used for all other occurrences of doors,
+/// particularly for doors having only 'Brep', or 'SurfaceModel'
+/// geometry without applying shape parameters.
+/// 
+/// The actual parameter of the door and/or its shape are defined
+/// by the IfcDoor as the occurrence definition (or project
+/// instance), or by the IfcDoorType as the specific definition (or
+/// project type). The following parameters are given:
+/// 
+/// at the IfcDoor or IfcDoorStandardCase for
+/// occurrence specific parameters. The IfcDoor
+/// specifies:
+/// 
+/// the door width and height
+/// the door opening direction (by the y-axis of the
+/// ObjectPlacement)
+/// 
+/// at the IfcDoorType, to
+/// which the IfcDoor is related by the inverse relationship
+/// IsDefinedBy pointing to IfcRelDefinesByType, for
+/// type parameters common to all occurrences of the same type.
+/// 
+/// the operation type (single swing, double swing, revolving,
+/// etc.)
+/// the door hinge side (by using two different styles for right
+/// and left opening doors)
+/// the construction material type
+/// the particular attributes for the lining by the
+/// IfcDoorLiningProperties
+/// the particular attributes for the panels by the
+/// IfcDoorPanelProperties
+/// 
+/// HISTORY New entity in IFC Release 1.0.
+/// IFC2x4 CHANGE The attributes PredefinedType and OperationType are added, the applicable type object has been changed to IfcDoorType.
+/// 
+/// Material Use Definition
+/// The material of the IfcDoor is defined by the
+/// IfcMaterialConstituentSet or as fall back by
+/// IfcMaterial and attached by the
+/// IfcRelAssociatesMaterial.RelatingMaterial. It is
+/// accessible by the inverse HasAssociations
+/// relationship.
+/// The following keywords for
+/// IfcMaterialConstituentSet.MaterialConstituents[n].Name
+/// shall be used:
+/// 
+/// 'Lining' - to indicate that the material constituent applies
+/// to to the door lining
+/// 'Framing' - to indicate that the material constituent applies
+/// to to the door panel(s), if not provided, the 'Lining' material
+/// information applied to panel(s) as well
+/// 'Glazing' - to indicate that the material constituent applies
+/// to to the glazing part
+/// 
+/// If the fall back single IfcMaterial is referenced, it
+/// applies to the lining and framing of the door.
+/// Property Set Use Definition:
+/// The property sets relating to the IfcDoor are defined
+/// by the IfcPropertySet and attached by the
+/// IfcRelDefinesByProperties relationship. It is accessible
+/// by the inverse IsDefinedBy relationship. The following
+/// property set definitions specific to the IfcDoor are part
+/// of this IFC release:
+/// 
+/// Pset_DoorCommon: common property set for all
+/// door occurrences
+/// Pset_DoorWindowGlazingType: specific property
+/// set for the glazing properties of the door glazing, if
+/// available
+/// Pset_DoorWindowShadingType: specific property
+/// set for the shading properties of the door glazing, if
+/// available
+/// 
+/// Quantity Use Definition
+/// The quantities relating to the IfcDoor are defined by
+/// the IfcElementQuantity and attached by the
+/// IfcRelDefinesByProperties relationship. It is accessible
+/// by the inverse IsDefinedBy relationship. The following
+/// base quantities are defined and should be exchanged with the
+/// IfcElementQuantity.Name = 'BaseQuantities'. Other
+/// quantities can be defined being subjected to local standard of
+/// measurement with another string value assigned to
+/// MethodOfMeasurement. Quanties shall be never assigned to
+/// the IfcDoorType.
+/// 
+/// Qto_DoorBaseQuantities: base quantities for
+/// all door occurrences.
+/// 
+/// Containment Use Definition
+/// The IfcDoor, as any subtype of
+/// IfcBuildingElement, may participate in two different
+/// containment relationships as shown in Figure 96. The first (and in most implementation
+/// scenarios mandatory) relationship is the hierachical spatial
+/// containment, the second (optional) relationship is the
+/// aggregation within anelement assembly.
+/// 
+/// The IfcDoor is places within the project spatial
+/// hierarchy using the objectified relationship
+/// IfcRelContainedInSpatialStructure, refering to it by its
+/// inverse attribute SELF\IfcElement.ContainedInStructure.
+/// Subtypes ofIfcSpatialStructureElement are valid spatial
+/// containers, with IfcBuildingStorey being the default
+/// container.
+/// The IfcDoor may be aggregated into an element assembly
+/// using the objectified relationship IfcRelAggregates,
+/// refering to it by its inverse attribute
+/// SELF\IfcObjectDefinition.Decomposes. Doors may be part of
+/// an IfcCurtainWall as a special focus subtype. In this case
+/// it should not be additionally contained in the project spatial
+/// hierarchy, i.e.SELF\IfcElement.ContainedInStructure
+/// should be NIL.
+/// 
+/// NOTE The containment shall be defined independently of the
+/// filling relationship, that is, even if the IfcDoor is a
+/// filling of an opening established by IfcRelFillsElement,
+/// it is also contained in the spatial structure by an
+/// IfcRelContainedInSpatialStructure.
+/// 
+/// Figure 96 — Door containment
+/// 
+/// Geometry Use Definitions:
+/// The geometric representation of IfcDoor is given by the
+/// IfcProductDefinitionShape, allowing multiple geometric
+/// representations. The IfcDoor, in case of an occurrance
+/// object, gets its parameter and shape from the IfcDoorType.
+/// If an IfcRepresentationMap (a block definition) is defined
+/// for the IfcDoorType, then the IfcDoor inserts it
+/// through the IfcMappedItem.
+/// Local Placement
+/// The local placement for IfcDoor is defined in its
+/// supertype IfcProduct. It is defined by the
+/// IfcLocalPlacement, which defines the local coordinate
+/// system that is referenced by all geometric representations.
+/// 
+/// The PlacementRelTo relationship of
+/// IfcLocalPlacement shall point to the local placement of
+/// the same element (if given), in which the IfcDoor is used
+/// as a filling (normally an IfcOpeningElement), as provided
+/// by the IfcRelFillsElement relationship.
+/// If the IfcDoor is not inserted into an
+/// IfcOpeningElement, then the PlacementRelTo
+/// relationship of IfcLocalPlacement shall point (if given)
+/// to the local placement of the same
+/// IfcSpatialStructureElement that is used in the
+/// ContainedInStructure inverse attribute or to a referenced
+/// spatial structure element at a higher level.
+/// If the relative placement is not used, the absolute placement
+/// is defined within the world coordinate system.
+/// 
+/// Geometric Representation
+/// Thegeometric representation of IfcDoor is defined
+/// using the following (potentiallymultiple)
+/// IfcShapeRepresentation's for its
+/// IfcProductDefinitionShape:
+/// 
+/// Profile: A'Curve3D'
+/// consisting of a single losed curve defining the outer boundary of
+/// the door (lining). The door parametric representation uses this
+/// profile in order to apply the door lining and panel parameter. If
+/// not provided, the profile of the IfcOpeningElement is
+/// taken.
+/// FootPrint: A 'GeometricCurveSet', or 'Annotation2D'
+/// representation defining the 2D shape of the door
+/// Body: A 'SweptSolid', 'SurfaceModel', or 'Brep'
+/// representation defining the 3D shape of the door.
+/// 
+/// In addition the parametric representation of a (limited) door
+/// shape is available by applying the parameters from
+/// IfcDoorType referencing IfcDoorLiningProperties and
+/// IfcDoorPanelProperties. The purpose of the parameter is
+/// described at those entities and below (door opening operation by
+/// door type).
+/// Profile -'Curve3D' representation
+/// The door profile is represented by a three-dimensional closed
+/// curve within a particular shape representation. The profile is
+/// used to apply the parameter of the parametric door
+/// representation.The following attribute values for the
+/// IfcShapeRepresentation holding this geometric
+/// representation shall be used:
+/// 
+/// RepresentationIdentifier : 'Profile'
+/// RepresentationType : 'Curve3D', only a single closed
+/// curve shall be contained in the set of
+/// IfcShapeRepresentation.Items.
+/// 
+/// A 'Profile' representation has to be provided if:
+/// 
+/// a parametric representation shall be applied to the door
+/// AND
+/// 
+/// thedoor is 'free standing', or
+/// the opening into which thedoor is inserted is not extruded
+/// horizontally (i.e. where the opening profile does not match
+/// thedoor profile)
+/// 
+/// FootPrint -'GeometricCurveSet' or 'Annotation2D'
+/// representation
+/// The door foot print is represented by a set of
+/// two-dimensionalcurves (or in case of 'Annotation2D' additional
+/// hatching and text) within a particular shape representation. The
+/// foot print is used for the planview representation of the
+/// door.The following attribute values for the
+/// IfcShapeRepresentation holding this geometric
+/// representation shall be used:
+/// 
+/// RepresentationIdentifier : 'FootPrint'
+/// RepresentationType : 'GeometricCurveSet', or
+/// 'Annotation2D'
+/// 
+/// Body - 'SweptSolid', 'SurfaceModel', or 'Brep'
+/// representation
+/// The door body is either represented parameterically (see
+/// parametric representation) or by explicit 3D shape. The 3D shape
+/// is given by using extrusion geometry, or surface models, or Brep
+/// models within a particular shape representation. The body is used
+/// for the model view representation of the door.The following
+/// attribute values for the IfcShapeRepresentation holding
+/// this geometric representation shall be used:
+/// 
+/// RepresentationIdentifier : 'Body'
+/// RepresentationType : 'SweptSolid', 'SurfaceModel', or
+/// 'Brep'
+/// 
+/// MappedRepresentation
+/// The 'FootPrint' and 'Body' geometric representation of
+/// IfcDoor can be shared among several identical doors using
+/// the 'MappedRepresentation'. The following attribute values for
+/// the IfcShapeRepresentation holding this geometric
+/// representation shall be used:
+/// 
+/// RepresentationIdentifier : 'FootPrint', 'Body'
+/// RepresentationType : 'MappedRepresentation'
+/// 
+/// The same constraints, as given for the 'FootPrint', 'Body'
+/// representation identifiers, shall apply to the
+/// MappedRepresentation of the
+/// IfcRepresentationMap.
+/// Parameteric Representation using parameters at
+/// IfcDoorType
+/// The parameters that defines the shape of the IfcDoor,
+/// are given at the IfcDoorType and the property sets, which
+/// are included in the IfcDoorType. The IfcDoor only
+/// defines the local placement which determines the opening
+/// direction of the door. The overall size of
+/// the IfcDoor to be used to apply the lining or panel
+/// parameter provided by the IfcDoorType is determined by the
+/// IfcShapeRepresentation with the RepresentationIdentifier =
+/// 'Profile'. Only in case of an IfcDoor inserted into an
+/// IfcOpeningElement using the IfcRelFillsElement
+/// relatioship, having a horizontal extrusion (along the y-axis of
+/// the IfcDoor), the overall size is determined by the
+/// extrusion profile of the IfcOpeningElement.
+/// NOTE The OverallWidth and
+/// OverallHeight parameters are for informational purpose
+/// only.
+/// The opening direction is determined by the local placement of
+/// IfcDoor and the OperationType of the door
+/// style as shown in Figure 97.
+/// NOTE There are different definitions in
+/// various countries on what a left opening or left hung or left

+/// 
+/// Type Use Definition
+/// IfcDoorStandardCase defines the occuurence of any door,
+/// common information about door types (or styles) is handled by
+/// IfcDoorType. The IfcDoorType (that has to be present)
+/// establishes the common type name, usage (opening direction and
+/// operation), common set of properties, including shape parameters,
+/// like lining thickness panel width, etc. and maybe an additional
+/// common shape representations (using IfcRepresentationMap).
+/// The IfcDoorType is attached using the
+/// IfcRelDefinedByType.RelatingType objectified relationship
+/// and is accessible by the inverse IsDefinedBy attribute.
+/// Property Set Use Definition:
+/// The property sets relating to the IfcDoorStandardCase are
+/// defined at the supertype IfcDoor.
+/// Quantity Use Definition
+/// The quantities relating to the IfcDoorStandardCase are
+/// defined at the supertype IfcDoor.
+/// Containment Use Definition
+/// The containment use definitions relating to the
+/// IfcDoorStandardCase are defined at the supertype
+/// IfcDoor.
+/// Geometry Use Definitions:
+/// The geometric representation of IfcDoorStandardCase is
+/// given by the IfcProductDefinitionShape, allowing multiple
+/// geometric representations. Included are:
+/// Local Placement
+/// The use of local placement is defined at the supertype
+/// IfcDoor.
+/// Geometric Representations
+/// The geometric representation of IfcDoorStandardCase is
+/// defined using the following multiple shape representations for its
+/// definition:
+/// 
+/// Profile: a three-dimensional closed curve within a
+/// particular shape representation. The profile is used to apply the
+/// parameter of the parametric door representation. The profile around
+/// the edges of the opening is used to apply the door lining and door
+/// panel shape parameter.
+/// MappedRepresentation: A SweptSolid, SurfaceModel, or
+/// Brep Representation or a CSG additionally defining the 3D shape of
+/// the standard door in addition to the parametric representation by
+/// applying the IfcDoorLiningProperties and an the
+/// IfcDoorPanelProperties to the Profile representation.
+/// 
+/// Profile representation
+/// The door profile is represented by a three-dimensional closed
+/// curve within a particular shape representation. The profile is used
+/// to apply the parameter of the parametric door
+/// representation. The following attribute values for the
+/// IfcShapeRepresentation holding this geometric representation
+/// shall be used:
+/// 
+/// RepresentationIdentifier : 'Profile'
+/// RepresentationType : 'Curve3D' or 'GeometricCurveSet',
+/// in case of 'GeometricCurveSet' only a single closed curve shall be
+/// contained in the set of IfcShapeRepresentation.Items.
+/// 
+/// The following additional constraints apply to the 'Profile'
+/// representation type:
+/// 
+/// Curve: being an IfcPolyline defining a
+/// rectangle.
+/// Position: The curve shall lie in the xz plane of the
+/// object placement coordinate (the y coordinate values of the
+/// IfcCartesianPoint's shall be 0.).
+/// 
+/// Figure 98 illustrates applying the door lining parameters to the door profile shape representation.  The profile defines the outer boundary to which the door lining parameters relate as:
+/// 
+/// IfcDoorLiningProperties.LiningDepth starting at distance defined by LiningOffset going into the positive y direction.
+/// IfcDoorLiningProperties.LiningThickness offset into the inner side of the rectangle.
+/// IfcDoorLiningProperties.LiningOffset distance along the positive y direction to where the LiningDepth applies.
+/// IfcDoorLiningProperties.ThresholdThickness starting at the bottom edge of the rectangle into the inner side of the rectangle
+/// IfcDoorLiningProperties.ThresholdDepth starting at distance defined by LiningOffset going into the positive y direction.
+/// IfcDoorLiningProperties.TransomOffset starting at the bottom edge of the rectangle (along local x axis) into the inner side of the rectangle, distance provided as percentage of overall height. Distance to the centre line of the transom.

+/// IfcGrid ia a planar design
+/// grid defined in 3D space used as an aid in locating structural and

+/// is defined by a 3D coordinate system (and thereby the design grid
+/// can be used in plan, section or in any position relative to the
+/// world coordinate system). The position can be relative to the
+/// object placement of other products or grids. The XY plane of the 3D
+/// coordinate system is used to place the grid axes, which are 2D
+/// curves (for example, line, circle, trimmed curve, polyline, or composite
+/// curve).
+/// The inherited attributes Name and Description can
+/// be used to define a descriptive name of the grid and to indicate
+/// the grid's purpose. A grid is defined by (normally) two, or
+/// (in case of a triangular grid) three lists of grid axes. The
+/// following table shows some examples.
+/// A grid may support a rectangular layout (Figure 28), a radial layout (Figure 29), or a triangular layout (Figure 30).

+/// Informal Proposition
+/// 
+/// Grid axes, which are referenced in different lists of axes
+/// (UAxes, VAxes, WAxes) shall not be parallel.
+/// Grid axes should be defined such as there are no two grid axes
+/// which intersect twice (see Figure 31).
+/// 
+/// left side: ambiguous intersections A1 and A2, a grid containing
+/// such grid axes is not a valid design grid.
+/// right side: the conflict can be resolved by splitting one grid
+/// axis in a way, such as no ambiguous intersections exist.
+/// 
+/// Figure 31 — Grid intersections
+/// 
+/// Geometry Use Definitions
+/// The geometric representation of IfcGrid is given by the
+/// IfcProductDefinitionShape, allowing geometric
+/// representations. Included are:
+/// Local Placement
+/// The local placement for IfcGrid is defined in its
+/// supertype IfcProduct. It is defined by the
+/// IfcLocalPlacement, which defines the local coordinate system
+/// that is referenced by all geometric representations.
+/// 
+/// The PlacementRelTo relationship of
+/// IfcLocalPlacement shall point (if given) to the local
+/// placement of the same IfcSpatialStructureElement, which is
+/// used in the ContainedInStructure inverse attribute, or to a
+/// spatial structure element at a higher level, referenced by
+/// that.
+/// If the relative placement is not used, the absolute placement
+/// is defined within the world coordinate system.
+/// 
+/// Geometric Representations
+/// Currently, the use of a 2D 'FootPrint' representation of type
+/// 'GeometricCurveSet' is supported.
+/// GeometricCurveSet representation
+/// The 2D geometric representation of IfcGrid is defined
+/// using the 'GeometricCurveSet' geometry. The following attribute
+/// values should be inserted
+/// 
+/// IfcShapeRepresentation.RepresentationIdentifier =
+/// 'FootPrint'.
+/// IfcShapeRepresentation.RepresentationType =
+/// 'GeometricCurveSet' .
+/// 
+/// The following constraints apply to the 2D representation:
+/// 
+/// The IfcGeometricCurveSet shall be an (and the only)
+/// Item of the IfcShapeRepresentation. It should contain
+/// an IfcGeometricCurveSet containing subtypes of
+/// IfcCurve, each representing a grid axis. Applicable subtypes
+/// of IfcCurve are: IfcPolyline, IfcCircle,
+/// IfcTrimmedCurve (based on BaseCurve referencing
+/// IfcLine or IfcCircle). 
+/// Each subtype of IfcCurve may have a curve style
+/// assigned, using IfcAnnotationCurveOccurrence referencing
+/// IfcCurveStyle.
+/// Optionally the grid axis labels may be added as
+/// IfcTextLiteral, and they may have text styles assigned,
+/// using IfcAnnotationTextOccurrence referencing
+/// IfcTextStyle.
+/// 
+/// As shown in Figure 32, the IfcGrid defines a placement coordinate system using the ObjectPlacement. The XY plane of the coordinate system is used to place the 2D grid axes. The Representation of IfcGrid is defined using IfcProductRepresentation, referencing an IfcShapeRepresentation, that includes IfcGeometricCurveSet as Items. All grid axes are added as IfcPolyline to the IfcGeometricCurveSet.
+/// 
+/// Figure 32 — Grid layout

+/// 
+/// Containment Use Definition
+/// The IfcMember, as any subtype of

+/// The IfcMember may be aggregated into an element
+/// assembly using the objectified relationship
+/// IfcRelAggregates, refering to it by its inverse attribute
+/// SELF\IfcObjectDefinition.Decomposes. Any subtype of
+/// IfcElement can be an element assembly, with

+/// case it should not be additionally contained in the project
+/// spatial hierarchy, i.e.
+/// SELF\IfcElement.ContainedInStructure should be
+/// NIL.
+/// 
+/// Geometry Use Definition
+/// The geometric representation of IfcMember is given by
+/// the IfcProductDefinitionShape, allowing multiple geometric
+/// representations. Included are:
+/// Local Placement
+/// The local placement for IfcMember is defined in its
+/// supertype IfcProduct. It is defined by the
+/// IfcLocalPlacement, which defines the local coordinate
+/// system that is referenced by all geometric representations.
+/// 
+/// The PlacementRelTo relationship of
+/// IfcLocalPlacement shall point (if given) to the local
+/// placement of the same IfcSpatialStructureElement, which is
+/// used in the ContainedInStructure inverse attribute, or to
+/// a spatial structure element at a higher level, referenced by
+/// that.
+/// If the relative placement is not used, the absolute placement
+/// is defined within the world coordinate system.
+/// 
+/// Geometric Representation
+/// Currently, the 'Axis', 'Body',
+/// and 'Box' representations are supported. The 'Box' representation
+/// includes the representation type 'BoundingBox' and is explained
+/// at IfcBuildingElement.
+/// Axis Representation
+/// The axis geometric representation of IfcMember is

+/// Definition from IAI: An IfcPlate is a planar and
+/// often flat part with constant thickness. A plate can be a
+/// structural part carrying loads between or beyond points of
+/// support, however it is not required to be load bearing.The
+/// location of the plate (being horizontal, vertical or sloped) is
+/// not relevant to its definition (in contrary to IfcWall and
+/// IfcSlab (as floor slab)).
+/// NOTE Plates arenormally made of steel, other
+/// metallic material, or by glass panels. However the definition of
+/// IfcPlate is material independent and specific material
+/// information shall be handled by using
+/// IfcAssociatesMaterial to assign a material specification
+/// to the IfcPlate.
+/// 
+/// NOTE Although not necessarily, plates are often add-on
+/// parts. This is represented by the IfcRelAggregates
+/// decomposition mechanism used to aggregate parts, such as
+/// IfcPlate, into a container element, e.g.
+/// IfcElementAssembly, or IfcCurtainWall.
+/// 
+/// NOTE The representation of a plate in a structural
+/// analysis model is provided by IfcStructuralSurfaceMember
+/// being part of an
+/// IfcStructuralAnalysisModel.
+/// An instance IfcPlate should preferably get its
+/// geometric representation and material assignment through the type
+/// definition by IfcPlateType assigned using the
+/// IfcRelDefinesByType relationship. This allows identical
+/// plates in a construction to be represented by the same instance
+/// of IfcPlateType.
+/// A plate may have openings, such as voids or recesses. They are
+/// defined by an IfcOpeningElement attached to the plate
+/// using the inverse relationship HasOpenings pointing to
+/// IfcRelVoidsElement. The position number of a plate as
+/// often used in steel construction is assigned through the
+/// attribute IfcElement.Tag
+/// The IFC specification provides two entities for plate
+/// occurrences:
+/// 
+/// IfcPlateStandardCase used for all occurrences of
+/// plates, that are prismatic and where the thickness parameter can
+/// be fully described by the IfcMaterialLayerSetUsage. These
+/// plates are always represented geometrically by a 'SweptSolid'
+/// geometry (or by a 'Clipping' geometry based on 'SweptSolid'), if
+/// a 3D geometric representation is assigned. In addition they have
+/// to have a corresponding IfcMaterialLayerSetUsage
+/// assigned.
+/// IfcPlate used for all other occurrences of plates,
+/// particularly for plates with changing thickness, or plates with
+/// non planar surfaces, and plates having only 'SurfaceModel' or
+/// 'Brep' geometry.
+/// 
+/// HISTORY New entity in
+/// IFC Release 2x2
+/// Type Use Definition
+/// The IfcPlate defines the occuurence of any plate,
+/// common information about plate types (or styles) is handled by
+/// IfcPlateType. The IfcPlateType (if present) may
+/// establish the commontype name, usage (or predefined) type,
+/// common set of properties, common material layer set, and common
+/// shape representations (using IfcRepresentationMap). The
+/// IfcPlateType is attached using the
+/// IfcRelDefinedByType.RelatingType objectified relationship
+/// and is accessible by the inverse IsTypedBy attribute.
+/// If no IfcPlateType is attached(i.e. if only occurrence
+/// information is given) the PredefinedType should be
+/// provided. If set to .USERDEFINED. a user defined value can be
+/// provided by the ObjectType attribute.
+/// Material Use Definition
+/// The material of the IfcPlate is defined by
+/// IfcMaterialLayerSet, or IfcMaterial and attached by
+/// the IfcRelAssociatesMaterial.RelatingMaterial. It
+/// is accessible by the inverse HasAssociations
+/// relationship.
+/// NOTE It is illegal to assign an

+/// concept.
+/// Material information can also be given at the

+/// occurrences of the same type.It is then accessible by the
+/// inverse IsTypedBy
+/// relationship pointing to IfcPlateType.HasAssociations and
+/// via IfcRelAssociatesMaterial.RelatingMaterial.
+/// Property Set Use Definition
+/// The property sets relating to the IfcPlate are defined
+/// by the IfcPropertySet and attached by the

+/// 
+/// Containment Use Definitions
+/// The IfcPlate, as any subtype of
+/// IfcBuildingElement, may participate in two different
+/// containment relationships. The first (and in most implementation
+/// scenarios mandatory) relationship is the hierachical spatial
+/// containment, the second relationship is the aggregation within
+/// anelement assembly.
+/// 
+/// TheIfcPlate is places within the project spatial
+/// hierarchy using the objectified relationship
+/// IfcRelContainedInSpatialStructure, referring to it by its
+/// inverse attribute SELF\IfcElement.ContainedInStructure.
+/// Subtypes ofIfcSpatialStructureElement are valid spatial
+/// containers, with IfcBuildingStorey being the default
+/// container.
+/// TheIfcPlate may be aggregated into an element
+/// assembly using the objectified relationship
+/// IfcRelAggregates, referring to it by its inverse attribute
+/// SELF\IfcObjectDefinition.Decomposes. Any subtype of
+/// IfcElement can be an element assembly, with
+/// IfcElementAssembly as a special focus subtype. In this
+/// case, no additional relationship to the spatial hierarchy shall
+/// be given (i.e.SELF\IfcElement.ContainedInStructure =
+/// NIL), the relationship to the spatial container is handled by the
+/// element assembly.
+/// 
+/// Geometry Use Definition
+/// The geometric representation of IfcPlate is
+/// given by the IfcProductDefinitionShape, allowing multiple
+/// geometric representations. Included are:
+/// Local Placement
+/// The local placement for IfcPlate is defined in
+/// its supertype IfcProduct. It is defined by the
+/// IfcLocalPlacement, which defines the local coordinate
+/// system that is referenced by all geometric representations.
+/// 
+/// The PlacementRelTo relationship of
+/// IfcLocalPlacement shall point (if given) to the local
+/// placement of the same IfcSpatialStructureElement, which is
+/// used in the ContainedInStructure inverse attribute, or to
+/// a spatial structure element at a higher level, referenced by
+/// that.
+/// 
+/// If the IfcPlate is part of an assembly, the
+/// PlacementRelTo relationship of IfcLocalPlacement
+/// shall point to the local placement of the container element, e.g.
+/// IfcElementAssembly,
+/// 
+/// If the relative placement is not used, the absolute placement
+/// is defined within the world coordinate system.
+/// 
+/// Geometric Representation
+/// Currently, the 'Surface',
+/// 'FootPrint', 'Body', and 'Box'
+/// representations are supported. The 'Box' representation includes
+/// the representation type 'BoundingBox' and is explained at
+/// IfcBuildingElement.

+/// surfacic model of the building (e.g. for analytical purposes, or
+/// for reduced Level of Detail representation).
+/// Body Representation
+/// The body representation of IfcPlate can be represented
+/// using the representation types 'SweptSolid', 'Clipping',
+/// 'MappedRepresentation', 'SurfaceModel', and 'Brep'. The
+/// representation types 'SurfaceModel' and 'Brep' are explained at

+/// Type Use Definition
+/// The IfcPlateStandardCase defines the occuurence of any
+/// plate, common information about plate types (or styles) is handled
+/// by IfcPlateType. The IfcPlateType (if present) may
+/// establish the common type name, usage (or predefined) type,

+/// shape representations (using IfcRepresentationMap). The
+/// IfcPlateType is attached using the
+/// IfcRelDefinedByType.RelatingType objectified relationship
+/// and is accessible by the inverse IsDefinedBy attribute.
+/// The IfcPlateStandardCase defines in addition that the
+/// IfcPlateType should have a unique
+/// IfcMaterialLayerSet, that is referenced by
+/// the IfcMaterialLayerSetUsage assigned to all
+/// occurrences of this plate type.
+/// 
+/// Figure 107 illustrates assignment of IfcMaterialLayerSetUsage and IfcMaterialLayerSet to the IfcPlateStandardCase as the plate occurrence and to the IfcPlateType. The same IfcMaterialLayerSet shall be shared by many occurrences of IfcMaterialLayerSetUsage. This relationship shall be consistent to the relationship between the IfcPlateType and the IfcPlateStandardCase.
+/// 
+///  
+/// Figure 107 — Plate type definition
+/// 
+/// Material Use Definition
+/// The material of the IfcPlateStandardCase is defined by
+/// IfcMaterialLayerSetUsage and attached by the
+/// IfcRelAssociatesMaterial.RelatingMaterial. It is
+/// accessible by the inverse HasAssociations relationship.
+/// Multi-layer plates can be represented by refering to several
+/// IfcMaterialLayer's within the IfcMaterialLayerSet
+/// that is referenced from the
+/// IfcMaterialLayerSetUsage. 
+/// Material information can also be given at the
+/// IfcPlateType, defining the common attribute data for all
+/// occurrences of the same type. It is then accessible by the
+/// inverse IsDefinedBy relationship pointing to
+/// IfcPlateType.HasAssociations and via
+/// IfcRelAssociatesMaterial.RelatingMaterial. See Type Use
+/// Definition for additional agreements for standard plates.
+/// 
+/// As shown in Figure 108, the following conventions shall be met:
+/// 
+/// The reference coordinate system is the coordinate system established by the IfcExtrudedAreaSolid.Position.
+/// The reference plane is the plane defined by the extruded profile of IfcExtrudedAreaSolid.SweptSolid. The IfcMaterialLayerSetUsage.OffsetFromReferenceLine is given as a distance from this plane.
+/// The IfcMaterialLayerSetUsage.DirectionSense defines how the IfcMaterialLayer's are assigned to the reference plane. POSITIVE means in direction to the positive z-axis of the reference coordinate system.
+/// The IfcMaterialLayerSetUsage.OffsetFromReferenceLine is the distance parallel to the reference plane and always perpendicular to the base (XY) plane of the reference coordinate system. This is independent of a potential non-perpendicular extrusion given by IfcExtrudedAreaSolid.ExtrudedDirection <> 0.,0.,1. A positive value of IfcMaterialLayerSetUsage.OffsetFromReferenceLine would then point into the positive z-axis of the reference coordinate system.
+/// The Thickness of each IfcMaterialLayer shall be the parallel distance (measured perpendicular to the base plane). The TotalThickness of the IfcMaterialLayerSet is the sum of all layer thicknesses and in case of a perpendicular extrusion identical with IfcExtrudedAreaSolid.Depth
+/// The IfcMaterialLayerSetUsage.LayerSetDirection i always AXIS3.

+/// Definition from ISO 6707-1:1989: Construction enclosing the building from above.
+/// The IfcRoof is a description of the total roof. It acts as a container entity, that aggregates all components of the roof, it represents. The aggregation is handled via the IfcRelAggregates relationship, relating an IfcRoof with the related roof elements, like slabs (represented by IfcSlab), rafters and purlins (represented by IfcBeam), or other included roofs, such as dormers (represented by IfcRoof).
+/// 
+/// HISTORY New Entity in IFC Release 2.0.
+/// IFC2x4 CHANGE Attribute ShapeType renamed to PredefinedType.
+/// 
+/// Property Set Use Definition:
+/// The property sets relating to the IfcRoof are defined
+/// by the IfcPropertySet and attached by the
+/// IfcRelDefinesByProperties relationship. It is accessible
+/// by the inverse IsDefinedBy relationship. The following
+/// property set definitions specific to the IfcRoof are part
+/// of this IFC release:
+/// 
+/// Pset_RoofCommon: common property set for all
+/// roof occurrences
+/// 
+/// The quantities relating to the IfcRoof are defined by
+/// the IfcElementQuantity and attached by the
+/// IfcRelDefinesByProperties relationship. It is accessible
+/// by the inverse IsDefinedBy relationship. The following
+/// base quantities are defined and should be exchanged with the
+/// IfcElementQuantity.MethodOfMeasurement = 'BaseQuantities'.
+/// Other quantities can be defined being subjected to local standard
+/// of measurement with another string value assigned to Name
+/// and a value provided for MethodOfMeasurement. Quantities
+/// shall never be assigned to the IfcRoofType.
+/// The individual quantities shall only be given at
+/// IfcRoof, it is not decomposed into the individual parts,
+/// e.g. IfcSlab as roof slabs.
+/// 
+/// Qto_RoofBaseQuantities: base quantities for
+/// all roof occurrences.
+/// 
+/// Containment Use Definition
+/// The IfcRoof, as any subtype of
+/// IfcBuildingElement, may participate in two different
+/// containment relationships. The first (and in most implementation
+/// scenarios mandatory) relationship is the hierachical spatial
+/// containment, the second (optional) relationship is the
+/// aggregation within an element assembly.
+/// 
+/// The IfcRoof is placed within the project spatial
+/// hierarchy using the objectified relationship
+/// IfcRelContainedInSpatialStructure, referring to it by its
+/// inverse attribute SELF\IfcElement.ContainedInStructure.
+/// Subtypes of IfcSpatialStructureElement are valid spatial
+/// containers, with IfcBuildingStorey being the default
+/// container.
+/// The IfcRoof may be aggregated into an element assembly
+/// using the objectified relationship IfcRelAggregates,
+/// referring to it by its inverse attribute
+/// SELF\IfcObjectDefinition.Decomposes. Any subtype of
+/// IfcElement can be an element assembly, with
+/// IfcRoof, the overall roof, as a special focus subtype. In
+/// this case it should not be additionally contained in the project
+/// spatial hierarchy, i.e.
+/// SELF\IfcElement.ContainedInStructure should be NIL.
+/// 
+/// NOTE A roof contained in another roof could
+/// be the representation of a dormer.
+/// The IfcRoof may be an aggregate i.e. being composed by
+/// other elements and acting as an assembly using the objectified
+/// relationship IfcRelAggregates, referring to it by its
+/// inverse attribute SELF\IfcObjectDefinition.IsDecomposedBy.
+/// Components of a roof are described by instances of subtypes of
+/// IfcBuildingElement (e.g. IfcSlab, IfcBeam,
+/// IfcColumn, IfcBuildingElementPart) that are
+/// aggregated to form a complex roof. In this case, the contained
+/// elements should not be additionally contained in the project
+/// spatial hierarchy, i.e. the inverse attribute
+/// SELF\IfcElement.ContainedInStructure of the aggregated
+/// elements should be NIL.
+/// 
+/// Figure 118 illustrates roof containment, where only the IfcRoof as the aggregate
+/// is included in the spatial structure.
+/// 
+/// Figure 118 — Roof containment
+/// 
+/// Geometry Use Definitions:
+/// The geometric representation of IfcRoof is given by the
+/// IfcProductDefinitionShape, allowing multiple geometric
+/// representations. Independent geometric representations should
+/// only be used when the IfcRoof is not defined as an
+/// aggregate. If defined as an aggregate, the geometric
+/// representation is the sum of the representation of the components
+/// within the aggregate.
+/// NOTE View definitions and implementer
+/// agreements may restrict the IfcRoof to not have an
+/// independent geometry, but to always require aggregated elements
+/// to represent the shape of the roof.
+/// NOTE If the IfcRoof has aggregated elements to
+/// represent the shape of the roof, then only those elements shall
+/// have openings, not the IfcRoof
+/// itself.
+/// Local Position
+/// The local placement for IfcRoof is defined in its
+/// supertype IfcProduct. It is defined by the
+/// IfcLocalPlacement, which defines the local coordinate
+/// system that is referenced by all geometric representations.
+/// 
+/// The PlacementRelTo relationship of
+/// IfcLocalPlacement shall point (if given) to the local
+/// placement of the same IfcSpatialStructureElement that is
+/// used in the ContainedInStructure inverse attribute or to a
+/// referenced spatial structure element at a higher level..
+/// If the relative placement is not used, the absolute placement
+/// is defined within the world coordinate system.
+/// 
+/// If the LocalPlacement is given for the IfcRoof,
+/// then all components, which are aggregated to the roof should use
+/// this placement as their relative placement.
+/// Geometric Representation
+/// The IfcRoof may have an independent geometric representation
+/// or may be an aggregate with elements holding the geometric
+/// representation of the roof.
+/// Geometric representation by own shape
+/// representation
+/// If the IfcRoof has no components defined (empty set of
+/// SELF\IfcObject.IsDecomposedBy) then the IfcRoof may
+/// be represented by an independent IfcShapeRepresentation.
+/// The following attribute values for the IfcShapeRepresentation
+/// holding this geometric representation shall be used:
+/// 
+/// RepresentationIdentifier : 'Body'
+/// RepresentationType : 'SweptSolid', 'Clipping',
+/// 'SurfaceModel', or 'Brep'
+/// 
+/// Geometric representation by aggregated elements
+/// If the IfcRoof has components (referenced by
+/// SELF\IfcObject.IsDecomposedBy) then no independent
+/// geometric representation shall defined for the IfcRoof.
+/// The IfcRoof is then geometrically represented by the
+/// geometric representation of its components. The components are
+/// accessed via
+/// SELF\IfcObject.IsDecomposedBy[1].RelatedObjects. The
+/// geometric representations that are supported for the aggregated
+/// elements are defined with each element. See geometric use
+/// definition for IfcSlab, IfcBeam, IfcColumn,
+/// IfcBuildingElementPart and other subtypes of
+/// IfcBuildingElement.

+/// NOTE There is a representation of slabs for

+/// 
+/// NOTE An arbitrary planar element to which this semantic

+/// A slab may have openings, such as floor openings, or recesses.
+/// They are defined by an IfcOpeningElement attached to the
+/// slab using the inverse relationship HasOpenings pointing
+/// to IfcRelVoidsElement.
+/// The IFC specification provides three entities for slab
+/// occurrences:
+/// 
+/// IfcSlabStandardCase used for all occurrences of slabs,
+/// that are prismatic and where the thickness parameter can be fully
+/// described by the IfcMaterialLayerSetUsage. These slabs are
+/// always represented geometrically by a 'SweptSolid' geometry (or
+/// by a 'Clipping' geometry based on 'SweptSolid'), if a 3D
+/// geometric representation is assigned. In addition they have to
+/// have a corresponding IfcMaterialLayerSetUsage
+/// assigned.
+/// IfcSlabElementedCase used for occurrences of slabs
+/// which are aggregated from subordinate elements, following
+/// specific decomposition rules expressed by the mandatory use of
+/// IfcRelAggregates relationship.
+/// IfcSlab used for all other occurrences of slabs,
+/// particularly for slabs with changing thickness, or slabs with non
+/// planar surfaces, and slabs having only 'SweptSolid' or 'Brep'
+/// geometry.
+/// 
+/// HISTORY New entity in IFC Release 2.0, it is a merger of the two previous entities
+/// IfcFloor, IfcRoofSlab, introduced in IFC Release 1.0
+/// 
+/// Type Use Definition
+/// The IfcSlab defines the occurrence of any slab, common
+/// information about slab types (or styles) is handled by
+/// IfcSlabType. The IfcSlabType (if present) may
+/// establish the commontype name, usage (or predefined) type,
+/// common set of properties, common material layer set, and common
+/// shape representations (using IfcRepresentationMap). The
+/// IfcSlabType is attached using the
+/// IfcRelDefinedByType.RelatingType objectified relationship
+/// and is accessible by the inverse IsTypedBy attribute.
+/// If no IfcSlabType is attached(i.e. if only occurrence
+/// information is given) the PredefinedType should be
+/// provided. Values of the enumeration are .FLOOR. (the default),
+/// .ROOF., .LANDING., .BASESLAB. If set to .USERDEFINED. a user
+/// defined value can be provided by the ObjectType
+/// attribute.
+/// Material Use Definition
+/// The material of the IfcSlab is defined by
+/// IfcMaterialLayerSet, or IfcMaterial and attached by
+/// the IfcRelAssociatesMaterial.RelatingMaterial. It
+/// is accessible by the inverse HasAssociations relationship.
+/// Multi-layer slabs can be represented by referring to several
+/// IfcMaterialLayer's within the
+/// IfcMaterialLayerSet.
+/// NOTE It is illegal to assign an
+/// IfcMaterialLayerSetUsage to an IfcSlab. Only the
+/// subtype IfcSlabStandardCase supports this
+/// concept.
+/// NOTE Prismatic slabs, where the main face of
+/// the slab is extruded along the slab thickness, are exchanged as
+/// IfcSlabStandardCase, The material for
+/// IfcSlabStandardCase shall be defined
+/// byIfcMaterialLayerSetUsage. Multi-layer slabs can be
+/// represented by referring to several IfcMaterialLayer's
+/// within the IfcMaterialLayerSet.
+/// Material information can also be given at the
+/// IfcSlabType, defining the common attribute data for all
+/// occurrences of the same type.It is then accessible by the
+/// inverse IsTypedBy
+/// relationship pointing to IfcSlabType.HasAssociations and
+/// via IfcRelAssociatesMaterial.RelatingMaterial.
+/// Property Set Use Definition:
+/// The property sets relating to the IfcSlab are defined
+/// by the IfcPropertySet and attached by the
+/// IfcRelDefinesByProperties relationship. It is accessible
+/// by the inverse IsDefinedBy relationship. The following
+/// property set definitions specific to the IfcSlab are part
+/// of this IFC release:
+/// 
+/// Pset_SlabCommon: common property set for all
+/// slab occurrences
+/// 
+/// Property sets can also be given at the IfcSlabType,
+/// defining the common property data for all occurrences of the same
+/// type.It is then accessible by the inverse IsTypedBy relationship pointing to
+/// IfcSlabType.HasPropertySets. If both are given, then the
+/// properties directly assigned to IfcSlab overrides the
+/// properties assigned to IfcSlabType.
+/// Quantity Use Definition
+/// The quantities relating to the IfcSlab and
+/// IfcSlabStandardCase are defined by the
+/// IfcElementQuantity and attached by the
+/// IfcRelDefinesByProperties relationship. It is accessible
+/// by the inverse IsDefinedBy relationship. The following
+/// base quantities are defined and should be exchanged with the
+/// IfcElementQuantity.Name = 'BaseQuantities'. Other
+/// quantities can be defined being subjected to local standard of
+/// measurement with another string value assigned to Name and
+/// a value provided for MethodOfMeasurement. Quantities shall
+/// never be assigned to the IfcSlabType.
+/// 
+/// Qto_SlabBaseQuantities: base quantities for
+/// all slab occurrences.
+/// 
+/// Containment Use Definition
+/// The IfcSlab, as any subtype of
+/// IfcBuildingElement, may participate in two different
+/// containment relationships. The first (and in most implementation
+/// scenarios mandatory) relationship is the hierarchical spatial
+/// containment, the second (optional) relationship is the
+/// aggregation within anelement assembly.
+/// 
+/// TheIfcSlab is places within the project spatial
+/// hierarchy using the objectified relationship
+/// IfcRelContainedInSpatialStructure, referring to it by its
+/// inverse attribute SELF\IfcElement.ContainedInStructure.
+/// Subtypes ofIfcSpatialStructureElement are valid spatial
+/// containers, with IfcBuildingStorey being the default
+/// container.
+/// TheIfcSlab may be aggregated into an element assembly
+/// using the objectified relationship IfcRelAggregates,
+/// referring to it by its inverse attribute
+/// SELF\IfcObjectDefinition.Decomposes. Any subtype of
+/// IfcElement can be an element assembly, with
+/// IfcElementAssembly as a special focus subtype.
+/// In this case it should not be additionally contained in the
+/// project spatial hierarchy,
+/// i.e.SELF\IfcElement.ContainedInStructure should be
+/// NIL.
+/// 
+/// The IfcSlabmay also be an aggregate i.e. being
+/// composed by other elements and acting as an assembly using the
+/// objectified relationship IfcRelAggregates, referring to it
+/// by its inverse attribute
+/// SELF\IfcObjectDefinition.IsDecomposedBy. Components of a
+/// slab are described by instances of subtypes of
+/// IfcBuildingElement, with IfcBuildingElementPart as
+/// a special focus subtype that are aggregated to form a complex
+/// slab. In this case, the contained elements should not be
+/// additionally contained in the project spatial hierarchy, i.e. the
+/// inverse attribute SELF\IfcElement.ContainedInStructure of
+/// IfcBuildingElementPart (or other subtypes of
+/// IfcBuildingElement) should be NIL.
+/// Geometry Use Definition
+/// The geometric representation of IfcSlab is given by the
+/// IfcProductDefinitionShape, allowing multiple geometric
+/// representation. Included are:
+/// NOTE. If the IfcSlab is of type Landing
+/// and is used within an IfcStair or IfcRamp, the
+/// special agreements to handle stair and ramp geometry will also
+/// affect the geometric representation of the
+/// IfcSlab.
+/// Local Placement
+/// The local placement for IfcSlab is defined in its
+/// supertype IfcProduct. It is defined by the
+/// IfcLocalPlacement, which defines the local coordinate
+/// system that is referenced by all geometric representations.
+/// 
+/// The PlacementRelTo relationship of
+/// IfcLocalPlacement shall point (if given) to the placement
+/// of the local placement of the same
+/// IfcSpatialStructureElement that is used in the
+/// ContainedInStructure inverse attribute or to a referenced
+/// spatial structure element at a higher level.
+/// If the IfcSlab is of type Landing and is used by an
+/// IfcStair or IfcRamp, and this container class
+/// defines its own local placement, then the PlacementRelTo
+/// relationship of IfcLocalPlacement shall point (if given)
+/// to the local placement of the aggregate.
+/// If the relative placement is not used, the absolute placement
+/// is defined within the world coordinate system.
+/// 
+/// Geometric Representation
+/// Currently, the 'Surface',
+/// 'FootPrint', 'Body', and 'Box'
+/// representations are supported. The 'Box' representation includes
+/// the representation type 'BoundingBox' and is explained at
+/// IfcBuildingElement.

+/// The body representation of IfcSlab can be represented
+/// using the representation types 'SweptSolid', 'Clipping',
+/// 'SurfaceModel', and 'Brep'. The representation types
+/// 'SurfaceModel' and 'Brep' are explained at

+/// Definition from IAI: The IfcStructuralAnalysisModel is used to assemble all information needed to represent a structural analysis model.  It encompasses certain general properties (such as analysis type), references to all contained structural members, structural supports or connections, as well as loads and the respective load results.
+/// 
+/// Important functionalities for the description of an analysis model are derived from existing IFC entities:
+/// 
+/// From IfcSystem it inherits the ability to couple the analysis model via IfcRelServicesBuildings to one or more IfcBuildings as necessary.
+///   From IfcGroup it inherits the inverse attribute IsGroupedBy, pointing to the relationship class IfcRelAssignsToGroup.  This allows to group structural members (instances of IfcStructuralMember), and supports (instances of IfcStructuralConnection) which belong to a specific analysis model.
+///   NOTE:  Loads (as instances of IfcStructuralAction) are not included through IsGroupedBy.  Loads are assigned through the LoadedBy attribute relationship, using load groups as a grouping mechanism.  Only top-level load groups should be referenced via LoadedBy, i.e. load combinations if any load combinations exist, or load cases if no load combinations exist in this analysis model.
+///   NOTE:  Results (as instances of IfcStructuralReaction) are not included through IsGroupedBy.  Results are assigned through the HasResults attribute relationship, using result groups as a grouping mechanism.
+/// 
+/// From IfcObject it inherits the inverse attribute IsDecomposedBy pointing to the relationship class IfcRelNests. It provides the hierarchy between the separate (partial) analysis models.
+/// 
+/// HISTORY: New entity in IFC 2x2.
+/// 
+/// IFC 2x4 change:  Attribute SharedPlacement and informal propositions added, allowing for easy retrieval of the common object placement and for specification of the analysis model's coordiante system before any structural item is instantiated.  WHERE rule added.
+/// 
+/// Informal propositions:
+/// 
+/// If one or more structural item (instance of a subtype of IfcStructuralItem) is grouped into an IfcStructuralAnalysisModel, the attribute SharedPlacement shall be provided with a value.
+///   The ObjectPlacements of all structural items which are grouped into the same instance of IfcStructuralAnalysisModel shall refer to the same instance of IfcObjectPlacement as IfcStructuralAnalysisModel.SharedPlacement.
+/// 
+/// NOTE  This rule is necessary to achieve consistent topology representations.  The topology representations of structural items in an analysis model are meant to share vertices and edges und must therefore have the same object placement.

+/// Containment Use Definition
+/// The IfcWall (and the subtype
+/// IfcWallStandardCase) as any subtype of
+/// IfcBuildingElement, may participate in two different
+/// containment relationships. The first (and in most implementation
+/// scenarios mandatory) relationship is the hierarchical spatial
+/// containment, the second (optional) relationship is the
+/// aggregation within anelement assembly.
+/// 
+/// The IfcWall is places within the project spatial
+/// hierarchy using the objectified relationship
+/// IfcRelContainedInSpatialStructure, referring to it by its
+/// inverse attribute SELF\IfcElement.ContainedInStructure.
+/// Subtypes ofIfcSpatialStructureElement are valid spatial
+/// containers, with IfcBuildingStorey being the default
+/// container.
+/// TheIfcWall may be aggregated into an element assembly
+/// using the objectified relationship IfcRelAggregates,
+/// referring to it by its inverse attribute
+/// SELF\IfcObjectDefinition.Decomposes. Any subtype of
+/// IfcElement can be an element assembly, with
+/// IfcElementAssembly as a special focus subtype.
+/// In this case the wall should not be additionally contained in the
+/// project spatial hierarchy,
+/// i.e.SELF\IfcElement.ContainedInStructure should be
+/// NIL.
+/// 
+/// TheIfcWallmay also be an aggregate i.e. being
+/// composed by other elements and acting as an assembly using the
+/// objectified relationship IfcRelAggregates, referring to it
+/// by its inverse attribute
+/// SELF\IfcObjectDefinition.IsDecomposedBy. Components of a
+/// wall are described by instances of IfcBuildingElementPart
+/// that are aggregated to form a complex wall.
+/// In this case, the containedIfcBuildingElementPart's
+/// should not be additionally contained in the project spatial
+/// hierarchy, i.e. the inverse attribute
+/// SELF\IfcElement.ContainedInStructure of
+/// IfcBuildingElementPart should be NIL.

+/// Definition form ISO 6707-1:1989: Construction for
+/// closing a vertical or near vertical opening in a wall or pitched
+/// roof that will admit light and may admit fresh air.
+/// The window is a building element
+/// that is predominately used to provide natural light and fresh
+/// air. It includes vertical and horizontal opening (e.g. skylights
+/// or light domes). It includes constructions with swinging,
+/// pivoting, sliding, or revolving panels and fixed panels. A window
+/// consists of a lining and one or several panels.
+/// The IfcWindow defines a particular occurrence of a
+/// window inserted in the spatial context of a project. A window
+/// can:
+/// 
+/// be inserted into an IfcOpeningElement using the
+/// IfcRelFillsElement relationship, , then the IfcDoor
+/// has an inverse attribute FillsVoids provided,
+/// 
+/// NOTE View definitions or
+/// implementer agreements may restrict the relationship to only
+/// include one window (or door) into one opening.
+/// 
+/// be part of an element assembly, often an
+/// IfcCurtainWall, using the IfcRelAggregates
+/// relationship, then the inverse attribute Decomposes is
+/// provided.
+/// or be a "free standing" window, then the IfcWindow has
+/// no inverse attributes FillsVoids or Decomposes
+/// provided.
+/// 
+/// The IFC specification provides two entities for window
+/// occurrences:
+/// 
+/// IfcWindowStandardCase used for all occurrences of
+/// windows, that have a 'Profile' shape representation defined to
+/// which a set of shape parameters for lining and framing properties
+/// apply. Additionally it requires the provision of an
+/// IfcWindowType that references one
+/// IfcWindowLiningProperties and on to many
+/// IfcWindowPanelProperties.
+/// 
+/// NOTE see
+/// IfcWindowStandardCase for all specific constraints imposed
+/// by this subtype.
+/// 
+/// IfcWindow used for all other occurrences of windows,
+/// particularly for windows having only 'Brep', or 'SurfaceModel'
+/// geometry without applying shape parameters.
+/// 
+/// The actual parameter of the window and/or its shape is defined
+/// at the IfcWindow as the occurrence definition (or project
+/// instance), or by the IfcWindowType as the specific definition (or
+/// project type). The following parameters are given:
+/// 
+/// at the IfcWindow or IfcWindowStandardCase for
+/// occurrence specific parameters. The IfcWindow
+/// specifies:
+/// 
+/// the window width and height
+/// the window opening direction (by the y-axis of the
+/// ObjectPlacement)
+/// 
+/// at the IfcWindowType to
+/// which the IfcWindow is related by the inverse relationship
+/// IsDefinedBy pointing to IfcRelDefinesByType, for
+/// type parameters common to all occurrences of the same type.
+/// 
+/// the partitioning type (single panel, double panel, tripel
+/// panel, more panels)
+/// the operation type (swing, tilt and turn, pivot revolve,
+/// fixed case ment, etc.)
+/// the window panel hinge side (by using two different styles
+/// for right and left opening windows)
+/// the construction material type
+/// the particular attributes for the lining by the
+/// IfcWindowLiningProperties
+/// the particular attributes for the panels by the
+/// IfcWindowPanelProperties
+/// 
+/// HISTORY New entity in IFC Release 1.0.
+/// IFC2x4 CHANGE The attributes PredefinedType and OperationType are added, the applicable type object has been changed to IfcDoorType.
+/// 
+/// Material Use Definition
+/// The material of the IfcWindow is defined by the
+/// IfcMaterialConstituentSet or as fall back by
+/// IfcMaterial and attached by the
+/// IfcRelAssociatesMaterial.RelatingMaterial. It is
+/// accessible by the inverse HasAssociations
+/// relationship.
+/// The following keywords for
+/// IfcMaterialConstituentSet.MaterialConstituents[n].Name
+/// shall be used:
+/// 
+/// 'Lining' - to indicate that the material constituent applies
+/// to to the window lining
+/// 'Framing' - to indicate that the material constituent applies
+/// to to the window panel(s), if not provided, the 'Lining' material
+/// information applied to panel(s) as well
+/// 'Glazing' - to indicate that the material constituent applies
+/// to to the glazing part
+/// 
+/// If the fall back single IfcMaterial is referenced, it
+/// applies to the lining and framing of the window.
+/// Property Set Use Definition:
+/// The property sets relating to the IfcWindow are defined
+/// by the IfcPropertySet and attached by the
+/// IfcRelDefinesByProperties relationship. It is accessible
+/// by the inverse IsDefinedBy relationship. The following
+/// property set definitions specific to the IfcWindow are
+/// part of this IFC release:
+/// 
+/// Pset_WindowCommon: common property set for all
+/// window occurrences
+/// Pset_DoorWindowGlazingType: specific property
+/// set for the glazing properties of the window glazing, if
+/// available
+/// Pset_DoorWindowShadingType: specific property
+/// set for the shading properties of the window glazing, if
+/// available
+/// 
+/// Quantity Use Definition
+/// The quantities relating to the IfcWindow are defined by
+/// the IfcElementQuantity and attached by the
+/// IfcRelDefinesByProperties relationship. It is accessible
+/// by the inverse IsDefinedBy relationship. The following
+/// base quantities are defined and should be exchanged with the
+/// IfcElementQuantity.Name = 'BaseQuantities'. Other
+/// quantities can be defined being subjected to local standard of
+/// measurement with another string value assigned to
+/// MethodOfMeasurement. Quanties shall be never assigned to
+/// the IfcWindowStyle.
+/// 
+/// Qto_WindowBaseQuantities: base quantities for
+/// all window occurrences.
+/// 
+/// Containment Use Definition
+/// 
+/// The IfcWindow, as any subtype of
+/// IfcBuildingElement, may participate in two different
+/// containment relationships. The first (and in most implementation
+/// scenarios mandatory) relationship is the hierachical spatial
+/// containment, the second (optional) relationship is the
+/// aggregation within anelement assembly.
+/// 
+/// The IfcWindow is placed within the project spatial
+/// hierarchy using the objectified relationship
+/// IfcRelContainedInSpatialStructure, refering to it by its
+/// inverse attribute SELF\IfcElement.ContainedInStructure.
+/// Subtypes ofIfcSpatialStructureElement are valid spatial
+/// containers, with IfcBuildingStorey being the default
+/// container.
+/// The IfcWindow may be aggregated into an element
+/// assembly using the objectified relationship
+/// IfcRelAggregates, refering to it by its inverse attribute
+/// SELF\IfcObjectDefinition.Decomposes. Windows may be part
+/// of an IfcCurtainWall as a special focus subtype. In this
+/// case it should not be additionally contained in the project
+/// spatial hierarchy,
+/// i.e.SELF\IfcElement.ContainedInStructure should be
+/// NIL.
+/// 
+/// Figure 141 illustrates window containment.
+/// NOTE The containment shall be defined independently of the filling relationship, that is, even if the IfcWindow is a filling of an opening established by IfcRelFillsElement, it is also contained in the spatial structure by an IfcRelContainedInSpatialStructure.
+/// 
+/// Figure 141 — Window containment
+/// 
+/// Geometry Use Definitions:
+/// The geometric representation of IfcWindow is given by
+/// the IfcProductDefinitionShape, allowing multiple geometric
+/// representation. The IfcWindow, in case of an occurrence
+/// object, gets its parameter and shape from the
+/// IfcWindowType. If an IfcRepresentationMap (a block
+/// definition) is defined for the IfcWindowType, then the
+/// IfcWindow inserts it through the IfcMappedItem
+/// (refered to by IfcShapeRepresentation.Items).
+/// Local Placement
+/// The local placement for IfcWindow is defined in its
+/// supertype IfcProduct. It is defined by the
+/// IfcLocalPlacement, which defines the local coordinate
+/// system that is referenced by all geometric representations.
+/// 
+/// The PlacementRelTo relationship of
+/// IfcLocalPlacement shall point to the local placement of
+/// the same element (if given), in which the IfcWindow is
+/// used as a filling (normally an IfcOpeningElement), as
+/// provided by the IfcRelFillsElement relationship.
+/// If the IfcWindow is not inserted into an
+/// IfcOpeningElement, then the PlacementRelTo
+/// relationship of IfcLocalPlacement shall point (if given)
+/// to the local placement of the same
+/// IfcSpatialStructureElement that is used in the
+/// ContainedInStructure inverse attribute or to a referenced
+/// spatial structure element at a higher level.
+/// If the relative placement is not used, the absolute placement
+/// is defined within the world coordinate system.
+/// 
+/// Geometric Representation
+/// Thegeometric representation of IfcWindow is defined
+/// using the following (potentiallymultiple)
+/// IfcShapeRepresentation's for its
+/// IfcProductDefinitionShape:
+/// 
+/// Profile: A'Curve3D'
+/// consisting of a single losed curve defining the outer boundary of
+/// the window (lining). Thewindow parametric representation uses
+/// this profile in order to apply thewindow lining and panel
+/// parameter. If not provided, the profile of the
+/// IfcOpeningElement is taken.
+/// FootPrint: A 'GeometricCurveSet', or 'Annotation2D'
+/// representation defining the 2D shape of thewindow
+/// Body: A 'SweptSolid', 'SurfaceModel', or 'Brep'
+/// representation defining the 3D shape of thewindow.
+/// 
+/// In addition the parametric representation of a
+/// (limited)window shape is available by applying the parameters
+/// fromIfcWindowType
+/// referencingIfcWindowLiningProperties
+/// andIfcWindowPanelProperties. The purpose of the parameter
+/// is described at those entities and below (parametric
+/// representation).
+/// Profile -'Curve3D' representation
+/// Thewindow profile is represented by a three-dimensional
+/// closed curve within a particular shape representation. The
+/// profile is used to apply the parameter of the parametricwindow
+/// representation.The following attribute values for the
+/// IfcShapeRepresentation holding this geometric
+/// representation shall be used:
+/// 
+/// RepresentationIdentifier : 'Profile'
+/// RepresentationType : 'Curve3D', only a single closed
+/// curve shall be contained in the set of
+/// IfcShapeRepresentation.Items.
+/// 
+/// A 'Profile' representation has to be provided if:
+/// 
+/// a parametric representation shall be applied to the
+/// windowAND
+/// 
+/// the window is 'free standing', or
+/// the opening into which the window is inserted is not extruded
+/// horizontally (i.e. where the opening profile does not match the
+/// window profile)
+/// 
+/// FootPrint -'GeometricCurveSet' or 'Annotation2D'
+/// representation
+/// Thewindow foot print is represented by a set of
+/// two-dimensionalcurves (or in case of 'Annotation2D' additional
+/// hatching and text) within a particular shape representation. The
+/// foot print is used for the plan view representation of
+/// thewindow.The following attribute values for the
+/// IfcShapeRepresentation holding this geometric
+/// representation shall be used:
+/// 
+/// RepresentationIdentifier : 'FootPrint'
+/// RepresentationType : 'GeometricCurveSet', or
+/// 'Annotation2D'
+/// 
+/// Body - 'SweptSolid', 'SurfaceModel', or 'Brep'
+/// representation
+/// Thewindow body is either represented parameterically (see
+/// parametric representation) or by explicit 3D shape. The 3D shape
+/// is given by using extrusion geometry, or surface models, or Brep
+/// models within a particular shape representation. The body is used
+/// for the model view representation of thewindow.The following
+/// attribute values for the IfcShapeRepresentation holding
+/// this geometric representation shall be used:
+/// 
+/// RepresentationIdentifier : 'Body'
+/// RepresentationType : 'SweptSolid', 'SurfaceModel', or
+/// 'Brep'
+/// 
+/// MappedRepresentation
+/// The 'FootPrint' and 'Body' geometric representation
+/// ofIfcWindow can be shared among several identicalwindows
+/// using the 'MappedRepresentation'. The following attribute values
+/// for the IfcShapeRepresentation holding this geometric
+/// representation shall be used:
+/// 
+/// RepresentationIdentifier : 'FootPrint', 'Body'
+/// RepresentationType : 'MappedRepresentation'
+/// 
+/// The same constraints, as given for the 'FootPrint', 'Body'
+/// representation identifiers, shall apply to the
+/// MappedRepresentation of the
+/// IfcRepresentationMap.
+/// Parameteric Representation using parameters at
+/// IfcWindowType
+/// The parameters, which define the shape of the
+/// IfcWindow, are given at the IfcWindowType and the
+/// property sets, which are included in the IfcWindowType.
+/// The IfcWindow only defines the local placement.
+/// The overall size of the IfcWindow to
+/// be used to apply the lining or panel parameter provided by the
+/// IfcWindowType is determined by the IfcShapeRepresentation
+/// with the RepresentationIdentifier = 'Profile'. Only in case of an
+/// IfcWindow inserted into an IfcOpeningElement using
+/// the IfcRelFillsElement relatioship, having a horizontal
+/// extrusion (along the y-axis of the IfcDoor), the overall
+/// size is determined by the extrusion profile of the
+/// IfcOpeningElement.
+/// 
+/// Figure 142 illustrates the insertion of a window into the IfcOpeningElement by creating an instance of
+/// IfcWindow with PartitioningType = DoublePanelHorizontal. The parameters OverallHeight and OverallWidth show the extent of the window in the positive Z and X axis of the local placement of the window. The lining and the transom are created by the given parameters.

+/// Window opening operation by window type
+/// The parameters that defines the shape of the IfcWindow,
+/// are given at the IfcWindowType and the property sets,
+/// which are included in the IfcWindowType. The
+/// IfcWindow only defines the local placement which
+/// determines the opening direction of the window. The overall
+/// layout of the IfcWindow is determined by
+/// itsIfcWindowType.PartitioningType. Each window panel has
+/// its own operation type, provided by
+/// IfcWindowPanelProperties.OperationType. All window panels
+/// are assumed to open into the same direction (if relevant for the
+/// particular window panel operation. The hindge side (whether a
+/// window opens to the left or to the right) is determined by the
+/// IfcWindowPanelProperties.OperationType.
+/// NOTE There are different conventions in
+/// different countries on how to show the symbolic presentation of
+/// the window panel operation (the "triangles"). Either as seen from
+/// the exterior, or from the interior side. The following figures
+/// show the symbolics from the exterior side (the convention as used
+/// predominately in Europe).
+/// 
+/// Figure 144 illustrates window operation types.
+/// 
+/// The window panel (for side hung windows) opens always
+/// into the direction of the positive Y axis of the local placement.
+/// The determination of whether the window opens to the left or to

+/// 
+/// If the window should open to the other side, then the
+/// local placement has to be changed. It is still a left hung

+/// Definition from ISO 6707-1:1989: Structural member designed to carry loads between or beyond points of support, usually narrow in relation to its length and horizontal or nearly so.
+/// 
+/// An IfcBeam is a horizontal, or nearly horizontal, structural member that is capable of withstanding load primarily by resisting bending. It represents such a member from an architectural point of view. It is not required to be load bearing.
+/// 
+/// NOTE  The representation of a beam in a structural analysis model is provided by
+/// IfcStructuralCurveMember being part of an IfcStructuralAnalysisModel.
+/// 
+/// NOTE  For any longitudial structural member, not constrained to be predominately horizontal nor vertical, or where this semantic information is irrelevant, the entity IfcMember should be used.
+/// 
+/// The IFC specification provides two entities for beam occurrences:
+/// 
+/// IfcBeamStandardCase used for all occurrences of beams, that have a profile defined that is swept along a directrix. The profile might be changed uniformly by a taper definition along the directrix. The profile parameter and its cardinal point of insertion can be fully described by the IfcMaterialProfileSetUsage. These beams are always represented geometricly by an 'Axis' and a 'SweptSolid' or 'AdvancedSweptSolid' shape representation (or by a 'Clipping' geometry based on the swept solid), if a 3D geometric representation is assigned. In addition they have to have a corresponding IfcMaterialProfileSetUsage assigned.
+/// NOTE  View definitions and implementer agreements may further constrain the applicable geometry types, for example, by excluding tapering from an IfcBeamStandardCase implementation.
+/// 
+/// IfcBeam used for all other occurrences of beams, particularly for beams with changing profile sizes along the extrusion, or beams defined by non-linear extrusion, or beams having only 'Brep', or 'SurfaceModel' geometry.
+/// 
+/// HISTORY New entity in IFC Release 1.0
+/// 
+/// Type Use Definition
+/// IfcBeam defines the occuurence of any beam, common
+/// information about beam types (or styles) is handled by
+/// IfcBeamType. The IfcBeamType (if present) may
+/// establish the common type name, usage (or predefined) type,
+/// common material layer set, common set of properties and common
+/// shape representations (using IfcRepresentationMap). The
+/// IfcBeamType is attached using the
+/// IfcRelDefinedByType.RelatingType objectified relationship
+/// and is accessible by the inverse IsTypedBy attribute.
+/// If no IfcBeamType is attached (i.e. if only occurrence
+/// information is given) the PredefinedType should be provided.
+/// If set to .USERDEFINED. a user defined value can be provided by the
+/// ObjectType attribute.
+/// Material Use Definition
+/// The material of the IfcBeam is defined by the
+/// IfcMaterialProfileSet or as fallback by IfcMaterial
+/// and attached by the
+/// IfcRelAssociatesMaterial.RelatingMaterial. It is
+/// accessible by the inverse HasAssociations relationship.
+/// Note It is illegal to assign an
+/// IfcMaterialProfileSetUsage to an IfcBeam. Only the
+/// subtype IfcBeamStandardCase supports this
+/// concept.
+/// Material information can also be given at the
+/// IfcBeamType, defining the common attribute data for all
+/// occurrences of the same type. It is then accessible by the inverse
+/// IsTypedBy relationship pointing
+/// to IfcBeamType.HasAssociations and via
+/// IfcRelAssociatesMaterial.RelatingMaterial to
+/// IfcMaterialProfileSet or IfcMaterial. If both are
+/// given, then the material directly assigned to IfcBeam
+/// overrides the material assigned to IfcBeamType.
+/// Property Set Use Definition
+/// The property sets relating to the IfcBeam are defined by
+/// the IfcPropertySet and attached by the
+/// IfcRelDefinesByProperties relationship. It is accessible by
+/// the inverse IsDefinedBy relationship. The following property
+/// set definitions specific to the IfcBeam are part of this IFC
+/// release:
+/// 
+/// Pset_BeamCommon: common property set for all
+/// beam occurrences
+/// 
+/// Property sets can also be given at the IfcBeamType,
+/// defining the common property data for all occurrences of the same
+/// type. It is then accessible by the inverse IsTypedBy relationship pointing to
+/// IfcBeamType.HasPropertySets. If both are given, then the
+/// properties directly assigned to IfcBeam overrides the
+/// properties assigned to IfcBeamType.
+/// Quantity Use Definition
+/// The quantities relating to the IfcBeam are defined by the
+/// IfcElementQuantity and attached by the
+/// IfcRelDefinesByProperties relationship. It is accessible by
+/// the inverse IsDefinedBy relationship. The following base
+/// quantities are defined and should be exchanged with the
+/// IfcElementQuantity.Name = 'BaseQuantities'. Other quantities
+/// can be defined being subjected to local standard of measurement
+/// with another string value assigned to MethodOfMeasurement.
+/// Quanties shall be never assigned to the IfcBeamType.
+/// 
+/// Qto_BeamBaseQuantities: base quantities for all
+/// beam occurrences.
+/// 
+/// Containment Use Definition
+/// The IfcBeam, as any subtype of IfcBuildingElement,
+/// may participate in two different containment relationships. The
+/// first (and in most implementation scenarios mandatory) relationship
+/// is the hierachical spatial containment, the second (optional)
+/// relationship is the aggregation within an element assembly.
+/// 
+/// The IfcBeam is places within the project spatial
+/// hierarchy using the objectified relationship
+/// IfcRelContainedInSpatialStructure, refering to it by its
+/// inverse attribute SELF\IfcElement.ContainedInStructure.
+/// Subtypes of IfcSpatialStructureElement are valid spatial
+/// containers, with IfcBuildingStorey being the default
+/// container.
+/// The IfcBeam may be aggregated into an element assembly
+/// using the objectified relationship IfcRelAggregates,
+/// refering to it by its inverse attribute
+/// SELF\IfcObjectDefinition.Decomposes. Any subtype of
+/// IfcElement can be an element assembly, with
+/// IfcElementAssembly as a special focus subtype. In this case
+/// it should not be additionally contained in the project spatial
+/// hierarchy, i.e. SELF\IfcElement.ContainedInStructure should
+/// be NIL.
+/// 
+/// Geometry Use Definition
+/// The geometric representation of IfcBeam is given by the
+/// IfcProductDefinitionShape, allowing multiple geometric
+/// representations. Included are:
+/// Local Placement
+/// The local placement for IfcBeam is defined in its
+/// supertype IfcProduct. It is defined by the
+/// IfcLocalPlacement, which defines the local coordinate system
+/// that is referenced by all geometric representations.
+/// 
+/// The PlacementRelTo relationship of
+/// IfcLocalPlacement shall point (if given) to the local
+/// placement of the same IfcSpatialStructureElement, which is
+/// used in the ContainedInStructure inverse attribute, or to a
+/// spatial structure element at a higher level, referenced by that.
+/// 
+/// Exception: If the IfcBeam is part of an assembly, the
+/// PlacementRelTo relationship of IfcLocalPlacement
+/// shall point to the local placement of the container element, e.g.
+/// IfcElementAssembly,
+/// 
+/// If the relative placement is not used, the absolute placement
+/// is defined within the world coordinate system.
+/// 
+/// Geometric Representation
+/// Currently, the 'Axis', 'Body', and
+/// 'Box' representations are supported. The 'Box' representation
+/// includes the representation type 'BoundingBox' and is explained at

+/// Definition from IAI: The IfcBuildingElementProxy
+/// is a proxy definition that provides the same functionality as an
+/// IfcBuildingElement, but without having a predefined meaning
+/// of the special type of building element, it represents. Proxies can
+/// also be used as spatial place holders or provisions, that maybe
+/// later replaced by special types of elements.
+/// One use of the proxy object is a provision for voids, i.e. where
+/// a particular volume of space is requested by some engineering
+/// function that might later be accepted or rejected and if accepted
+/// potentially transformed into a void within a building element, like
+/// a wall opening, or a slab opening. The provision for voids is
+/// exchanged as an IfcBuildingElementProxy with the
+/// PredefinedType = ProvisionForVoid.
+/// Other usages of IfcBuildingElementProxy include:
+/// 
+/// The IfcBuildingElementProxy can be used to exchange
+/// special types of building elements for which the current IFC
+/// Release does not yet provide a semantic definition.
+/// The IfcBuildingElementProxy can also be used to
+/// represent building elements for which the participating
+/// applications can not provide additional semantic
+/// classification.
+/// 
+/// HISTORY  New entity
+/// in IFC Release 2x.
+/// IFC2x4 CHANGE  The attribute
+/// CompositionType has been replaced by PredefinedType,
+/// being a superset of the enumerators.
+/// Type Use Definition
+/// The IfcBuildingElementProxy defines the occuurence of any
+/// building element, common information about the types (or styles) is
+/// handled by IfcBuildingElementProxyType.
+/// The IfcBuildingElementProxyType (if present) may
+/// establish the common type name, usage (or predefined) type, common
+/// material, common set of properties and common shape representations
+/// (using IfcRepresentationMap). The
+/// IfcBuildingElementProxyType is attached using the
+/// IfcRelDefinedByType.RelatingType objectified relationship
+/// and is accessible by the inverse IsTypedBy attribute.
+/// 
+/// NOTE The IfcBuildingElementProxyType can be used
+/// to share common information among many occurrences of the same
+/// proxy without establishing a particular semantic meaning of the
+/// type.
+/// 
+/// If no IfcBuildingElementProxyType is attached (i.e. if
+/// only occurrence information is given) the PredefinedType
+/// should be provided. If set to .USERDEFINED. a user defined value
+/// can be provided by the ObjectType attribute.
+/// Material Use Definition
+/// The material of the IfcBuildingElementProxy is defined by
+/// IfcMaterial and attached by the
+/// IfcRelAssociatesMaterial.RelatingMaterial. It is
+/// accessible by the inverse HasAssociations relationship.
+/// Note It is illegal to assign an
+/// IfcMaterial to an IfcBuildingElementProxy with the
+/// PredefinedType = ProvisionForVoid.
+/// Material information can also be given at the
+/// IfcBuildingElementProxyType, defining the common attribute
+/// data for all occurrences of the same type. It is then
+/// accessible by the inverse IsTypedBy relationship pointing to
+/// IfcBuildingElementProxyType.HasAssociations and via
+/// IfcRelAssociatesMaterial.RelatingMaterial to
+/// IfcMaterial. If both are given, then the material directly
+/// assigned to IfcBuildingElementProxy overrides the material
+/// assigned to IfcBuildingElementProxyType.
+/// Property Set Use Definition:
+/// The property sets relating to the IfcBuildingElementProxy
+/// are defined by the IfcPropertySet and attached by the
+/// IfcRelDefinesByProperties relationship. It is accessible by
+/// the inverse IsDefinedBy relationship. The following property
+/// set definitions specific to the IfcBuildingElementProxy are
+/// part of this IFC release:
+/// 
+/// Pset_BuildingElementProxyCommon: common
+/// property set for all occurrences of building element proxies.
+/// Pset_BuildingElementProxyProvisionForVoid:
+/// specific property set for all occurrences of building element proxy
+/// with the PredefinedType: PROVISIONFORVOID.
+/// 
+/// Property sets can also be given at the
+/// IfcBuildingElementProxyType, defining the common property
+/// data for all occurrences of the same type. It is then
+/// accessible by the inverse IsTypedBy relationship pointing to
+/// IfcBuildingElementProxyType.HasPropertySets. If both are
+/// given, then the properties directly assigned to
+/// IfcBuildingElementProxy overrides the properties assigned to
+/// IfcBuildingElementProxyType.
+/// Containment Use Definition
+/// The IfcBuildingElementProxy, as any subtype of
+/// IfcBuildingElement, may participate in two different
+/// containment relationships. The first (and in most implementation
+/// scenarios mandatory) relationship is the hierachical spatial
+/// containment, the second (optional) relationship is the aggregation
+/// within an element assembly.
+/// 
+/// The IfcBuildingElementProxy is places within the project
+/// spatial hierarchy using the objectified relationship
+/// IfcRelContainedInSpatialStructure, refering to it by its
+/// inverse attribute SELF\IfcElement.ContainedInStructure.
+/// Subtypes of IfcSpatialStructureElement are valid
+/// spatial containers, with IfcBuildingStorey being the default
+/// container.
+/// The IfcBuildingElementProxy may be aggregated into an
+/// element assembly using the objectified relationship
+/// IfcRelAggregates, refering to it by its inverse attribute
+/// SELF\IfcObjectDefinition.Decomposes. Any subtype of
+/// IfcElement can be an element assembly, with
+/// IfcElementAssembly as a special focus subtype. In this case
+/// it should not be additionally contained in the project spatial
+/// hierarchy, i.e. SELF\IfcElement.ContainedInStructure
+/// should be NIL.
+/// 
+/// Geometry Use Definition
+/// The geometric representation of IfcBuildingElementProxy
+/// is given by the IfcProductDefinitionShape, allowing multiple
+/// geometric representations. Included are:
+/// Local Placement
+/// The local placement for any IfcBuildingElementProxy is
+/// defined in its supertype IfcProduct. It is defined by the
+/// IfcLocalPlacement, which defines the local coordinate system
+/// that is referenced by all geometric representations. The local
+/// placement can be given relativly.
+/// 
+/// The PlacementRelTo relationship of
+/// IfcLocalPlacement shall point (if given) to the local
+/// placement of the same IfcSpatialStructureElement, which is
+/// used in the ContainedInStructure inverse attribute, or to a
+/// spatial structure element at a higher level, referenced by
+/// that.
+/// If the relative placement is not used, the absolute placement
+/// is defined within the world coordinate system.
+/// 
+/// Geometric Representation
+/// Currently, the 'FootPrint', 'Body', and 'Box' representations
+/// are supported. The 'Box' representation includes the representation
+/// type 'BoundingBox' and is explained at
+/// IfcBuildingElement.
+/// FootPrint Representation
+/// Any building element proxy may be represented by a geometric
+/// curve set, given by a collection of 2D points and curves. The foot
+/// pring geometric representation of IfcBuildingElementProxy is
+/// defined using the 'FootPrint' representation.
+/// 
+/// RepresentationIdentifier: 'FootPrint'
+/// RepresentationType: 'GeometricCurveSet',
+/// 'Annotation2D'
+/// 
+/// Body Representation
+/// The body representation of IfcBuildingElementProxy can be
+/// represented using the representation types 'GeometricSet',
+/// 'SweptSolid', 'CSG' 'SurfaceModel', 'Brep', and
+/// 'MappedRepresentation'. The representation types 'SurfaceModel',
+/// 'Brep', and 'MappedRepresentation' are explained at
+/// IfcBuildingElement.
+/// GeometricSet Representation Type
+/// Any building element proxy may be represented by a geometric
+/// set, given by a collection of 2D and 3D points, curves, and
+/// surfaces. It represents the body of the proxy object, when no
+/// topological structure is available. The following attribute values
+/// for the IfcShapeRepresentation holding this geometric
+/// representation shall be used:
+/// 
+/// RepresentationIdentifier: 'Body'
+/// RepresentationType: 'GeometricSet'
+/// 
+/// SweptSolid Representation Type
+/// Any building element proxy may be represented by swept solid
+/// geometry (either by extrusion or by revolution). The following
+/// attribute values for the IfcShapeRepresentation holding this
+/// geometric representation shall be used:
+/// 
+/// RepresentationIdentifier: 'Body'
+/// RepresentationType: 'SweptSolid'
+/// 
+/// No further restrictions (e.g., for the profile or extrusion
+/// direction) are defined at this level. A single or multiple swept
+/// area solid(s) can be the Items of the
+/// IfcShapeRepresentation.
+/// CSG Representation Type
+/// Any building element proxy may be represented by a CSG primitive
+/// or CSG tree. The following attribute values for the
+/// IfcShapeRepresentation holding this geometric representation
+/// shall be used:
+/// 
+/// RepresentationIdentifier: 'Body'
+/// RepresentationType: 'CSG'
+/// 
+/// No further restrictions (e.g., for the depths of the CSG tree)
+/// are defined at this level.

+/// The distribution element IfcDistributionControlElement defines occurrence elements of a building automation control system that are used to impart control over elements of a distribution system.

+/// This class defines elements of a building automation control system. These are typically used to control distribution system elements to maintain  variables such as temperature, humidity, pressure, flow, power, or lighting levels, through the modulation, staging or sequencing of mechanical or electrical devices. The three general functional categories of control elements are as follows:
+/// 
+/// Impart control over flow control elements (IfcFlowController) in a distribution system such as dampers, valves, or relays, typically through the use of actuation (IfcActuator).
+/// Sensing elements (IfcSensor) that measure changes in the controlled variable such as temperature, humidity, pressure, or flow.
+/// Controllers (IfcController) typically classified according to the control action they seek to perform and generally responsible for making decisions about the elements under control.
+/// 
+/// Since this class and its subtypes typically relate to many different distribution flow elements (IfcDistributionFlowElement), the objectified relationship IfcRelFlowControlElements has been provided to relate control and flow elements as required.
+/// 
+/// IFC2x4 CHANGE: ControlElementId attribute deleted; replaced by classification usage.

+/// 
+/// Classification Use Definition

+/// 
+/// IfcClassification: Indicates an addressing scheme managed by the device where ReferenceTokens defines the format of the address to be specified at IfcClassificationReference.ItemReference.  A classification hierarchy may optionally be provided indicating detected or provisioned device addresses.
+/// IfcClassificationReference: Indicates the address of the control element where Identification uniquely identifies the element within the control system as determined by the ClassificationSource.  Several examples are illustrated:
+/// 
+/// 'BACnet': BACnetObjectIdentifier in the decimal form '12.15' (Digital Input #15) indicating type ID and instance ID.
+/// 'IP': IP Address in the decimal form '192.168.1.2' such as for an IPv4 network.
+/// 'OPC': Hierarchical ItemID in the alphanumeric form 'B204.Tank2.Temperature'
+/// 'X-10': Alphabetic and numeric code in the form 'B12' (House B, Device 12) indicating House Code and Device Code.
+/// 
+/// Figure 147 illustrates classification usage.
+/// 
+/// Figure 147 — Distribution control classification
+/// 
+/// Composition Use Definition
+/// The IfcDistributionControlElement may be decomposed into components using IfcRelAggregates where RelatingObject refers to the enclosing IfcDistributionControlElement and RelatedObjects contains one or more components.  Likewise, a control element may be aggregated within another element.  For example, a thermostat may contain temperature sensors, and a programmable logic controller may contain virtual (software-based) control elements.  Standard types for composition are defined at subtypes.
+/// 
+/// Connection Use Definition
+/// The IfcDistributionControlElement may be connected to other objects as follows using the indicated relationship:
+/// 
+/// IfcSpatialStructureElement (IfcRelContainedInSpatialStructure) : Indicates the spatial location containing the element.  If an element is aggregated within another element, then only the top-level element participates in this relationship.
+/// IfcElement (IfcRelConnectsElements) : Indicates physical connectivity with another element (but not embedding or flow control), such as a sensor attached to a wall.  IfcRelConnectsElements.RelatingElement refers to the anchored side (for example, wall hosting sensor).
+/// IfcDistributionPort (IfcRelConnectsPortToElement) : Indicates ports on the element which may be connected to other elements for control signal transmission or electric power.  Standard port names, types, and directions are defined at subtypes.
+/// IfcDistributionFlowElement (IfcRelFlowControlElements) : Indicates a flow element is sensed or controlled by the control element, such as a tank for a level sensor or a valve for an actuator.
+/// 
+/// Assignment Use Definition
+/// The IfcDistributionControlElement may be assigned to the following entities using relationships as indicated:
+/// 
+/// IfcDistributionSystem (IfcRelAssignsToGroup): Indicates a system containing interconnected devices, where control elements are typically part of a control system having PredefinedType=CONTROL.
+/// IfcPerformanceHistory (IfcRelAssignsToControl): Indicates realtime or historical infomation captured for the device.
+/// 
+/// The IfcDistributionControlElement may have assignments of its own using the IfcRelAssignsToProduct relationship where RelatingProduct refers to the IfcDistributionControlElement and RelatedObjects contains one or more objects of the following types: 
+/// 
+/// IfcTask: Indicates tasks used to purchase, install, renovate, demolish, operate, or otherwise act upon the element.  If the element has a type, available task types are assigned to the element type.
+/// IfcProcedure: Indicates procedures used to operate the element.  If the element has a type, available procedure types are assigned to the element type.
+/// IfcEvent: Indicates events raised by the element, sequenced by procedures to be followed.  If the element has a type, available event types are assigned to the element type.
+/// 
+/// Material Use Definition
+/// The material of the IfcDistributionControlElement is defined using one of the following entities:
+/// 
+/// IfcMaterialConstituentSet: For elements containing multiple materials, this indicates materials at named aspects.
+/// 
+/// IfcMaterial: For elements comprised of a single material, this indicates the material.
+/// 
+/// The material is attached by the RelatingMaterial attribute on the IfcRelAssociatesMaterial relationship.  It is accessible by the HasAssociations inverse attribute.  Material information can also be given at the IfcDistributionControlElementType, defining the common attribute data for all occurrences of the same type.  Standard names and material types are defined at subtypes.
+/// 
+/// Representation Use Definition
+/// The following shape representations are supported for subtypes of IfcDistributionControlElement, distinguished by IfcShapeRepresentation.RepresentationIdentifier:
+/// 
+/// 'Footprint': Represents the 2D footprint outline of the item having IfcShapeRepresentation.RepresentationType of 'GeometricCurveSet' and containing a single IfcGeometricCurveSet consisting of one or more IfcCurve subtypes such as IfcPolyline, IfcTrimmedCurve, IfcCompositeCurve, or IfcCircle.
+/// 
+/// 'Body': Represents the 3D shape of the item having IfcShapeRepresentation.RepresentationType of 'SurfaceModel', 'SolidModel', or any solid model specializations including 'Brep', 'AdvancedBrep', 'SweptSolid', 'AdvancedSweptSolid', 'CSG', 'Clipping', or 'SectionedSpine').
+/// 
+/// 'Clearance': Represents the 3D clearance volume of the item having RepresentationType of 'Surface3D'.  Such clearance region indicates space that should not intersect with the 'Body' representation of other elements, though may intersect with the 'Clearance' representation of other elements.  The particular use of clearance space may be for safety, maintenance, or other purpose.
+/// 
+/// For all representations, if a IfcDistributionControlElement occurrence is defined by a IfcDistributionControlElementType having a representation of the same identifier, then 'MappedRepresentation' should be used at the occurrence unless overridden.
+/// 
+/// If materials are defined, geometry of each representation (most typically the 'Body' representation) may be organized into shape aspects where styles may be derived by correlating IfcShapeAspect.Name to a corresponding material (IfcMaterialConstituent.Name).

Before publication, it may want to set the IfcChangeActionEnum to NOCHANGE to establish a baseline so that other application changes can be easily identified. Application B then receives this IFC dataset and adds a new object and sets IfcChangeActionEnum to ADDED with Application B defined as the OwningApplication. Application B then modifies an existing object and (re)defines the LastModifiedDate to the time of the modification, LastModifyingUser to the IfcPersonAndOrganization making the change, and sets the LastModifyingApplication to Application B. When Application A receives this modified dataset, it can determine which objects have been added and modified by Application B and either merge or reject these changes as necessary. Consequently, the intent is that an application only modifies the value of IfcChangeActionEnum when it does something to the object, with the further intent that a model server is responsible for clearing the IfcChangeActionEnum back to NOCHANGE when it is ready to be republished.

It may be used for angular measurement by surveyors or for other angular measurements where precision is required. Another usage is exact or approximate global positioning against a geographic coordinate systems using longitude and latitude.
+/// 
+/// NOTE: While the unit of measurement of the type IfcPlaneAngleMeasure depends on unit assignment (radian or degree or other derived units; globally at the IfcPoject or locally at an IfcMeasureWithUnit), the units of IfcCompoundPlaneAngleMeasure are always degrees, minutes, seconds, and millionth-seconds irrespective of unit assignments.
+/// 
+/// HISTORY New type in IFC Release 1.5.1.
+/// 
+/// Type: LIST [3:4] OF INTEGER
+/// 
+/// Value restrictions
+/// 
+/// The first integer measure is the number of degrees and is generally not range-restricted.  However, when IfcCompoundPlaneAngleMeasure is used to express geographic coordinates, only latitudes of [-90, 90] and longitudes of [-180, 180] are used in practice.
+/// The second integer measure is the number of minutes and shall be in the range (-60, 60).
+/// The third integer measure is the number of seconds and shall be in the range (-60, 60).
+/// The optional fourth integer measure is the number of millionth-seconds and shall be in the range (-1 000 000, 1 000 000).
+/// 
+/// Signedness
+/// 
+/// All measure components have the same sign (positive or negative).  It is therefore trivial to convert between floating point representation (decimal degrees) and compound representation regardless whether the angle is greater or smaller than zero.  Example:
+/// 
+/// LOCAL
+///   a : IfcPlaneAngleMeasure := -50.975864;  (* decimal degrees, -50° 58' 33" 110400 *)
+///   b : IfcPlaneAngleMeasure;
+///   c : IfcCompoundPlaneAngleMeasure;
+///   s : IfcText;
+/// END_LOCAL;
+/// 
+/// (* convert from float to compound *)
+///   c[1] :=    a;                                           -- -50
+///   c[2] :=   (a - c[1]) * 60;                              -- -58
+///   c[3] :=  ((a - c[1]) * 60 - c[2]) * 60;                 -- -33
+///   c[4] := (((a - c[1]) * 60 - c[2]) * 60 - c[3]) * 1.e6;  -- -110400
+/// 
+/// (* convert from compound to float *)
+///   b := c[1] + c[2]/60. + c[3]/3600. + c[4]/3600.e6;       -- -50.975864
+/// 
+/// Use in string representations
+/// 
+/// When a compound plane angle measure is formatted for display or printout, the signs of the fractional components will usually be discarded because, to a human reader, the sign of the first component alone already indicates the sense of the angle:
+/// 
+/// (* convert from compound to human-readable string *)
+///   s := FORMAT(c[1], '+##')     + "000000B0"
+///      + FORMAT(ABS(c[2]), '##') + ''''
+///      + FORMAT(ABS(c[3]), '##') + '"'
+///      + FORMAT(ABS(c[4]), '##');  -- -50° 58' 33" 110400
+/// 
+/// Another often encountered display format of latitudes and longitudes is to omit the signs and print N, S, E, W indicators instead, for example, 50°58'33"S.  When stored as IfcCompoundPlaneAngleMeasure however, a compound plane angle measure is always signed, with same sign of all components.

+/// Definition from CSS1 (W3C Recommendation): The 'font-weight' property selects the weight of the font. The values '100' to '900' form an ordered sequence, where each number indicates a weight that is at least as dark as its predecessor. The keyword 'normal' is synonymous with '400', and 'bold' is synonymous with '700'. Keywords other than 'normal' and 'bold' have been shown to be often confused with font names and a numerical scale was therefore chosen for the 9-value list. Values are:
+/// 
+/// normal 
+///   bold 
+///   100 | 200 | 300 | 400 | 500 | 600 | 700 | 800 | 900
+/// 
+/// Fonts (the font data) typically have one or more properties whose values are names that are descriptive of the "weight" of a font. There is no accepted, universal meaning to these weight names. Their primary role is to distinguish faces of differing darkness within a single font family. Usage across font families is quite variant; for example a font that you might think of as being bold might be described as being Regular, Roman, Book, Medium, Semi- or DemiBold, Bold, or Black, depending on how black the "normal" face of the font is within the design. Because there is no standard usage of names, the weight property values in CSS1 are given on a numerical scale in which the value '400' (or 'normal') corresponds to the "normal" text face for that family. The weight name associated with that face will typically be Book, Regular, Roman, Normal or sometimes Medium.
+/// 
+/// The association of other weights within a family to the numerical weight values is intended only to preserve the ordering of darkness within that family. However, the following heuristics tell how the assignment is done in typical cases:
+/// 
+/// If the font family already uses a numerical scale with nine values (such as with OpenType), the font weights should be mapped directly. 
+///   If there is both a face labeled Medium and one labeled Book, Regular, Roman or Normal, then the Medium is normally assigned to the '500'. 
+///   The font labeled "Bold" will often correspond to the weight value '700'. 
+///   If there are fewer then 9 weights in the family, the default algorithm for filling the "holes" is as follows. If '500' is unassigned, it will be assigned the same font as '400'. If any of the values '600', '700', '800' or '900' remains unassigned, they are assigned to the same face as the next darker assigned keyword, if any, or the next lighter one otherwise. If any of '300', '200' or '100' remains unassigned, it is assigned to the next lighter assigned keyword, if any, or the next darker otherwise. 
+/// 
+/// The following two examples illustrate the process. Assume four weights in the "Example1" family, from lightest to darkest: Regular, Medium, Bold, Heavy. And assume six weights in the "Example2" family: Book, Medium, Bold, Heavy, Black, ExtraBlack. Note how in the second example it has been decided not to assign "Example2 ExtraBlack" to anything.

+///   Topic 2: If the relationship between any two coordinate
+///   reference systems is known, coordinates can be transformed
+///   or converted to another coordinate reference system.
+///   Coordinate operations are divided into two subtypes:
+/// 
+/// Coordinate conversion – mathematical
+///   operation on coordinates that does not include any change
+///   of datum. The best-known example of a coordinate
+///   conversion is a map projection. The parameters describing
+///   coordinate conversions are defined rather than
+///   empirically derived. Note that some conversions have no
+///   parameters.
+/// 
+/// Coordinate transformation – mathematical
+///   operation on coordinates that usually includes a change
+///   of datum. The parameters of a coordinate transformation
+///   are empirically derived from data containing the
+///   coordinates of a series of points in both coordinate
+///   reference systems. This computational process is usually
+///   ‘over-determined’, allowing derivation of
+///   error (or accuracy) estimates for the transformation.
+///   Also, the stochastic nature of the parameters may result
+///   in multiple (different) versions of the same coordinate
+///   transformation. Because of this several transformations
+///   may exist for a given pair of coordinate reference
+///   systems, differing in their transformation method,
+///   parameter values and accuracy characteristics.
+/// 
+/// The coordinate operation is an
+///   abstract supertype to handle any operation (transformation
+///   or conversion) between two coordinate reference systems. It
+///   is meant to provide expandability for future versions,
+///   since currently only the conversion of a local engineering
+///   coordinate system into a map coordinate reference system is
+///   dealt with by the subtype IfcMapConversion.
+/// 
+/// By convention, a coordinate operation is given between the
+///   SourceCRS being the more local, or child coordinate
+///   reference system, and the TargetCRS being the more
+///   remote or parent coordinate reference system, in
+///   thespecial case the coordinate operation between the local
+///   engineering coordinate system of the construction project

+/// IfcProfileDef
+/// is the supertype of all definitions of standard and arbitrary profiles
+/// within IFC. It is used to define a standard set of commonly used
+/// section profiles by their parameters or by their explicit curve geometry.
+/// 
+/// Parameterized profiles are 2D primitives, which are used within the industry to describe cross
+///   sections by a description of its parameters.
+///   Arbitrary profiles are cross
+///   sections defined by an outer boundary as bounded curve, which may also
+///   include holes, defined by inner boundaries.
+///   Derived profiles, based on a
+///   transformation of a parent profile, are also part of the profile
+///   definitions available.
+///   In addition composite
+///   profiles can be defined, which include two or more profile definitions
+///   to define the resulting profile.
+/// 
+/// HISTORY  New class in IFC Release 1.5, the capabilities have been extended in IFC Release 2x.
+/// Profiles can now support swept surfaces and swept area solids with
+/// inner boundaries. It had been renamed from IfcAttDrivenProfileDef.
+/// 
+/// IFC2x4 CHANGE  Changed from ABSTRACT to non-abstract for uses which do not
+/// require an explicitly defined geometry.  Added inverse attributes HasProperties and HasExternalReference.
+/// 
+/// Use in material association
+/// 
+/// Beams, columns, and similarly shaped building elements and their type objects may
+/// be associated with a section profile definition, combined with material definition,
+/// by means of IfcRelAssociatesMaterial together with IfcMaterialProfileSet
+/// and IfcMaterialProfileSetUsage. This way, building elements and element types
+/// with same section and material can share a common section profile definition and
+/// association.
+/// 
+/// The profile definition in material association is required to be consistent with
+/// shape representations of the respective building elements.
+/// 
+/// A higher-level description of spatial aligment of the section profile of a member
+/// (such as centered, bottom-left, in the geometric centroid, and more) can be provided
+/// within IfcMaterialProfileSetUsage by means of a cardinal point reference.
+/// This can be used redundant to geometric data in order to convey design intent.
+/// 
+/// Use in shape models
+/// 
+/// Profile definitions are used within the geometry and geometric model
+/// resource to create either swept surfaces, swept area solids, or
+/// sectioned spines.
+/// 
+/// The purpose of the profile
+/// definition within the swept surfaces or swept area solids is to define
+/// a uniform cross section being swept:
+/// 
+/// along a line (extrusion) using IfcSurfaceOfLinearExtrusion or IfcExtrudedAreaSolid
+///   along a circular arc (revolution) using IfcSurfaceOfRevolution or IfcRevolvedAreaSolid
+///   along a directrix lying on a reference surface using IfcSurfaceCurveSweptAreaSolid
+/// 
+/// The purpose fo the profile
+/// definition within the sectioned spine is to define a varying cross
+/// sections at several positions along a spine curve. The subtype IfcDerivedProfileDef
+/// is particularly suited to provide the consecutive profiles to be based
+/// on transformations of the start profile and thus maintaining the
+/// identity of vertices and edges.
+/// 
+/// NOTE  Subtypes of the IfcProfileDef
+/// contain parameterized profiles (as subtypes of IfcParameterizedProfileDef)
+/// which establish their own 2D position coordinate system, profiles given
+/// by explicit curve geometry (either open or closed profiles) and two
+/// special types for composite profiles and derived profiles, based on a
+/// 2D Cartesian transformation.
+/// 
+/// An IfcProfileDef
+/// is treated as bounded area if it is used within swept area solids. In
+/// this case, the inside of the profile is part of the profile. The
+/// attribute ProfileType is set to AREA. An IfcProfileDef
+/// is treated as a curve if it is used within swept surfaces. In this
+/// case, the inside of the profile (if the curve is closed) is not part of
+/// the profile. The attribute ProfileType
+/// is set to CURVE.
+/// 
+/// Figure 320 illustrates use of parameterized profiles within a swept area solid.
+/// 
+/// Position
+/// The IfcProfileDef is defined within the underlying
+/// coordinate system which is defined by the swept surface or swept area solid
+/// that uses the profile definition. It is the xy plane
+/// 
+/// of IfcSweptSurface.Position or
+///   of IfcSweptAreaSolid.Position or
+///   of each list member of IfcSectionedSpine.CrossSectionPositions.
+/// 
+/// In the figure to the left, the z axis of the position coordinate system points outwards of the drawing plane.
+/// 
+/// Note: The subtype IfcParameterizedProfileDef optionally provides an additional 2D position coordinate system relative to the underlying coordinate system of the IfcProfileDef.
+/// 
+/// Sweeping
+/// 
+/// In the later use of the IfcProfileDef
+/// within the swept surface or swept area solid,  e.g. the IfcExtrudedAreaSolid
+/// (here used as an example), the profile boundaries (here based on the 2D
+/// position coordinate system of IfcParameterizedProfileDef)
+/// are placed within the xy plane of the 3D position coordinate system of
+/// the swept surface or swept area solid.
+/// 
+/// The profile is inserted into the underlying coordinate system either:
+/// 
+/// directly in case of using IfcArbitraryClosedProfileDef
+///   and IfcArbitraryOpenProfileDef,
+/// 
+/// through an intermediate position coordinate system in case of
+///   using IfcParameterizedProfileDef.
+/// 
+/// through an 2D Cartesian transformation operator (applied directly
+///   to the curve position when using arbitrary profile definitions,
+///   or applied to the position coordinate system when using parameterized
+///   profile definitions) in case of using IfcDerivedProfileDef.
+/// 
+/// when using IfcCompositeProfileDef the insertion depends on
+///   the subtype of the included sub-profiles.
+/// 
+/// Figure 320 — Profile sweeping
+/// 
+/// Profile types
+/// 
+/// Results of the different usage of the ProfileType attribute are demonstrated here. The ProfileType defines whether the inside (the bounded area) is part of the profile definition (Area) or not (Curve). Figure 321 illustrates the resulting area or curve depending on ProfileType.

+/// Profile specification by external reference
+/// 
+/// If the profile is standardized by a norm or a catalogue, a reference
+/// to this norm or catalogue should be provided by means of HasExternalReference.
+/// This inverse relationship is used to associate an IfcExternalReference (notably
+/// IfcClassificationReference or IfcLibraryReference) with the
+/// profile.
+/// 
+/// IfcClassificationReference is used to refer to a profile norm (a common standard or
+/// manufacturer's standard).  In this case,
+/// 
+/// IfcClassificationReference.ItemReference
+/// contains the formal profile designation from the norm.
+/// (On the other hand, IfcProfileDef.ProfileName contains a displayable name which may
+/// not necessarily be the same as the formal designation.)
+/// IfcClassificationReference.Name carries the short name of the profile norm.
+/// Optionally, the norm can be further described by
+/// IfcClassificationReference.ReferencedSource.
+/// 
+/// IfcLibraryReference is used to refer to a library which contains profile
+/// definitions. In this case,
+/// 
+/// IfcLibraryReference.ItemReference contains the identifier of the
+/// profile within the library and is meant to be machine-readable (in contrast to
+/// IfcProfileDef.ProfileName which should be human-readable).
+/// IfcLibraryReference.Location and .Name or .ReferencedLibrary

+/// 
+/// Direct instances of IfcProfileDef

+/// Usually, only subtypes of IfcProfileDef should be instantiated.
+/// In some special cases, e.g. if the profile object is used for purposes

+/// 
+/// Texture maps are defined in a 2D coordinate system (s, t) that ranges from [0.0, 1.0] in both directions. The bottom edge of the image corresponds to the S-axis of the texture map, and left edge of the image corresponds to the T-axis of the texture map. The lower-left pixel of the image corresponds to s=0, t=0, and the top-right pixel of the image corresponds to s=1, t=1. Texture maps may be viewed as two dimensional colour functions that, given an (s, t) coordinate, return a colour value colour(s, t).
+/// 
+/// If multiple surface textures are included in the
+/// IfcSurfaceStyleWithTextures applying them to a geometric

+/// whether the texture map is repeated outside the [0.0, 1.0] texture
+/// coordinate range, when applied to a geometric surface, or clamped
+/// to lie within the [0.0, 1.0] range. The TextureTransform
+/// applies a 2D non-uniform transformation to the texture before it is
+/// applied to a geometric surface.

+/// apply:
+/// 
+/// These parameters
+/// support changes to the size, orientation, and position of textures
+/// on shapes. Note that these operations appear reversed when viewed
+/// on the surface of geometry. For example, a scale value of (2
+/// 2) will scale the texture coordinates and have the net effect of
+/// shrinking the texture size by a factor of 2 (texture coordinates
+/// are twice as large and thus cause the texture to repeat). A
+/// translation of (0.5 0.0) translates the texture coordinates +.5
+/// units along the S-axis and has the net effect of translating the
+/// texture −0.5 along the S-axis on the geometry's surface. A
+/// rotation of π/2 of the texture coordinates results in a
+/// −π/2 rotation of the texture on the geometry.
+/// The center
+/// field specifies a translation offset in texture coordinate space
+/// about which the rotation and scale fields are
+/// applied. The scale field specifies a scaling factor in S and
+/// T of the texture coordinates about the center point.
+/// scale values shall be in the range (−∞,∞).
+/// The rotation field specifies a rotation in radians of the
+/// texture coordinates about the center point after the scale
+/// has been applied. A positive rotation value makes the texture
+/// coordinates rotate counterclockwise about the centre, thereby
+/// rotating the appearance of the texture itself clockwise. The

+/// IfcDerivedProfileDef defines the profile by transformation from the parent profile. The transformation is given by a two dimensional transformation operator.

+/// 
+/// The transformation effects the position, rotation, mirroring or scale of the profile at the underlying coordinate system, i.e. the coordinate system defined by the swept surface or swept area solid that uses the profile definition. It is the xy plane of either:

+/// 
+/// HISTORY: New entity in IFC Release 2x.
+/// 
+/// Figure 316 illustrates examples of derived profiles.
+/// 
+/// Parameter
+/// The IfcDerivedProfileDef
+/// is defined using the IfcCartesianTransformationOperator2D
+/// (CTO), which is applied to the parent profile definition. 
+/// 
+/// Example
+/// The example shows an uniform scaling and a transformation
+/// of an IfcRectangleProfileDef
+/// to match the lower-left cardinal point. The attributes of the CTO are:
+/// 
+/// Axis1 = NIL (defaults to 1.,0.)
+///   Axis2 = NIL (defaults to 0.,1.)
+///   LocalOrigin = IfcCartesianPoint(,)
+///   Scale = 2.
+/// 
+/// Note: The ParentProfile has a Position
+/// = IfcCartesianPoint(,) already.
+/// 
+/// Parameter
+/// The IfcDerivedProfileDef is defined using
+/// non uniform transformationsby applying the IfcCartesianTransformationOperator2DnonUniform
+/// as a subtype of the 2D CTO.
+/// 
+/// Example
+/// The example shows a non-uniform scaling and a translation of an IfcRectangleProfileDef
+/// to match the lower-left cardinal point. The attributes of the CTO are:
+/// 
+/// Axis1 = NIL (defaults to 1.,0.)
+///   Axis2 = NIL (defaults to 0.,1.)
+///   LocalOrigin = IfcCartesianPoint(0.,<1/2 YDim)
+///   Scale  = 1.
+///   Scale2 = 2.
+/// 
+/// Note: The ParentProfile has a Position
+/// = IfcCartesianPoint(,) already.
+/// 
+/// Parameter
+/// The IfcDerivedProfileDef
+/// is defined using mirroring by applying the IfcCartesianTransformationOperator2D
+/// (CTO) to the parent profile.
+/// 
+/// Example
+/// The example shows a mirroring of an IfcLShapeProfileDef
+/// to match the centre cardinal point. The attributes of the CTO are:
+/// 
+/// Axis1 = (-1.,0.)
+///   Axis2 = NIL (defaults to 0.,1.)
+///   LocalOrigin = IfcCartesianPoint(0.,0.)
+///   Scale = NIL (defaults to 1.)
+/// 
+/// Note: The ParentProfile has a Position = IfcCartesianPoint(0.,0.).

+/// present, is a finite, non-self-intersecting open curve in
+/// RM, that is, a connected 1-dimensional
+/// manifold. The bounds of an edge are two vertices, which need not

+/// Associated with an edge may be a geometric curve to locate the

+/// - the vertices need not be distinct
+/// 
+/// - Equation (2) shall hold.

+/// Definition from ISO/CD 10303-42:1992: A face is a topological
+///   entity of dimensionality 2 corresponding to the intuitive notion of a piece of
+///   surface bounded by loops. Its domain, if present, is an oriented, connected,
+///   finite 2-manifold in Rm. A face domain shall not have handles
+///   but it may have holes, each hole bounded by a loop. The domain of the
+///   underlying geometry of the face, if present, does not contain its bounds, and 0
+///   < Ξ < ∞. 
+///   A face is represented by its bounding loops, which are defined as face
+///   bounds. A face has a topological normal n and the tangent to a loop is t. For a
+///   loop bounding a face with defined geometry, the cross product n x t points
+///   toward the interior of the face. That is, each loop runs counter-clockwise
+///   around the face when viewed from above, if we consider the normal n to point
+///   up. With each loop is associated a BOOLEAN flag to signify whether the loop
+///   direction is oriented with respect to the face normal (TRUE) or should be
+///   reversed (FALSE).  
+///   A face shall have at least one bound, and the loops shall not intersect.
+///   One loop is optionally distinguished as the outer loop of the face. If so, it
+///   establishes a preferred way of embedding the face domain in the plane, in which
+///   the other bounding loops of the face are inside the outer bound. Because the
+///   face domain is arcwise connected, no inner loop will contain any other loop.
+///   This is true regardless of which embedding in the plane is chosen.  
+///   The edges and vertices referenced by the loops of a face form a graph,
+///   of which the individual loops are the connected components. The Euler equation
+///   (1) for this graph becomes: 
+/// 
+/// where Gli is the graph genus of the

+/// Definition from ISO/CD 10303-43:1992: An geometric representation item is a representation item that has the additional meaning of having geometric position or orientation or both. This meaning is present by virtue of:  
+/// 
+/// being a Cartesian point or a direction  
+///   referencing directly a Cartesian point or direction  
+///   referencing indirectly a Cartesian point or direction  
+/// 
+/// An indirect reference to a Cartesian point or direction means that a given geometric item references the Cartesian point or direction through one or more intervening geometry or topology items.  
+/// 
+/// EXAMPLE: Consider a circle. It gains its geometric position and orientation by virtue of a reference to axis2_placement (IfcAxis2Placement) that is turn references a cartesian_point (IfcCartesianPoint) and several directions (IfcDirection). 
+/// 
+/// EXAMPLE: Consider a manifold brep. A manifold_solid_brep (IfcManifoldSolidBrep) is a geometric_representation_item (IfcGeometricRepresentationItem) that through several layers of topological_representation_item's (IfcTopologicalRepresentationItem) references poly loops (IfcPolyLoop). Through additional intervening entities poly loops reference cartesian_point's (IfcCartesianPoint).
+/// 
+/// The derivation of the dimensionality of the IfcGeometricRepresentationItem is different to ISO 10303; there is a specific derived attribute at each class that defines the dimensionality, whereas ISO 10303 does it for the representation_context and requires all geometric_representation_item's to have the same dimensionality therein.  
+/// 
+/// The definition of swept area solids as geometric representation items is different to ISO 10303; it is based on a set of predefined profiles (or cross sections), that is, a set of parameterized geometric primitives widely supported in the industry. Those profiles are used to create volumes through extrusion, revolution and cross section based sweep operations.
+///

+/// IfcGeometricRepresentationSubContext defines the context that applies to several shape representations of a product being a sub context, sharing the WorldCoordinateSystem, CoordinateSpaceDimension, Precision and TrueNorth attributes with the parent IfcGeometricRepresentationContext.
+/// 
+/// The IfcGeometricRepresentationSubContext is used to define semantically distinguished representation types for different information content, dependent on the representation view and the target scale. It can be used to control the level of detail of the shape representation that is most applicable to this geometric representation context. addition the sub context is used to control the later appearance of the IfcShapeRepresentation within a plot view.

+/// 
+/// NOTE Refer to the implementation guide and agreements for

+/// 
+/// The IfcMaterialLayerSetUsage is always assigned to an

+/// The assignment between asubtype of IfcElement and the

+/// 
+/// Use definition
+/// The IfcMaterialLayerSetUsage is primarily intended to
+/// be associated with planar building elements having a constant
+/// thickness. With further agreements on the interpretation of
+/// LayerSetDirection, the usage can be extended also to other
+/// cases, e.g. to curved building elements, provided that the
+/// material layer thicknesses are constant.
+/// Generally, an element may be layered in any of its primary
+/// directions, denoted by its x, y or z axis. The geometry use
+/// definitions at eachspecific types of building element will
+/// determine the applicableLayerSetDirection.
+/// 
+/// The following examples illustrate how the IfcMaterialLayerSetUsage attributes (LayerSetDirection, DirectionSense, OffsetFromReferenceLine) can
+/// be used in different cases. The normative material use definitions are documented at each element (how these shall be used).
+/// 
+/// Figure 286 shows an example of the use of IfcMaterialLayerSetUsage aligned to the axis of a wall.
+/// 
+/// EXAMPLE  For a standard wall with extruded
+/// geometric representation (vertical extrusion), the layer set
+/// direction will be perpendicular to extrusion direction,
+/// andcan be derived from the direction of the wall
+/// axis. With the DirectionSense(positive in
+/// this example) the individual IfcMaterialLayers are
+/// assigned consecutively right-to-left or left-to-right. For a
+/// curved wall, "direction denoting the wall thickness" can be
+/// derived from the direction of the wall axis, and it will remain
+/// perpendicular to the wall path. The
+/// DirectionSenseapplies as well.
+/// 
+/// NOTE  According to the IfcWallStandardCase material use
+/// definition the LayerSetDirection for
+/// IfcWallStandardCase is always AXIS2 (i.e. along the
+/// y-axis), as shown in this example.
+/// 
+/// Figure 286 — Material layer set usage for wall
+/// 
+/// Figure 287 shows an example of the use of IfcMaterialLayerSetUsage aligned to a slab.
+/// 
+/// EXAMPLE For a slab with perpendicular
+/// extruded geometric representation, the LayerSetDirection
+/// will coincide with the extrusion direction (in positive or
+/// negative sense). In this example, the material layer set base is
+/// the extruded profile and consistent with the
+/// IfcExtrudedAreaSolid.Position,with the
+/// DirectionSensebeing positive, the
+/// individual IfcMaterialLayers are built up from the base
+/// towards positive z direction in this case.
+/// 
+/// NOTE According to the IfcSlabStandardCase
+/// material use definition the LayerSetDirection for
+/// IfcSlabStandardCase is always AXIS3 (i.e. along the
+/// z-axis).
+/// 
+/// Figure 287 — Material layer set usage for slab
+/// 
+/// Figure 288 shows an example of the use of IfcMaterialLayerSetUsage aligned to a roof slab with non-perpendicular extrusion.
+/// 
+/// EXAMPLE For a slab with non-perpendicular
+/// extruded geometric representation, the guidelines above apply as
+/// well. The material layer thickness and the
+/// OffsetFromReferenceLine is always measured

+/// An IfcObjectDefinition is the generalization of any

+/// context is a specific kind of object definition as it provides the
+/// project or library context in which object types and object
+/// occurrences are defined.
+/// Objects are independent pieces of information that might contain

+/// 
+/// Assignment of other objects - an assignment relationship
+/// (IfcRelAssigns) that refers to other types of objects and
+/// creates a bi-directional association. The semantic of the
+/// assignment is established at the level of the subtypes of the
+/// general IfcRelAssigns relationship. There is no dependency
+/// implied a priori by the assignment.
+/// Association to external resources - an association
+/// relationship (IfcRelAssociates) that refers to external
+/// sources of information (most notably a classification or document)
+/// and creates a uni-directional association. There is no dependency
+/// implied by the association.
+/// Aggregation of other objects - an aggregation
+/// relationship (IfcRelAggregates) that establishes an
+/// unordered, spatial whole/part relation and creates a bi-directional
+/// relation. There is an implied dependency established.
+/// Nesting of other objects - a nesting relationship
+/// (IfcRelNests) that establishes an ordered, non-spatial
+/// whole/part relation and creates a bi-directional relation. There is
+/// an implied dependency established.
+/// Declaration within a context - a relationship
+/// (IfcRelDeclares) of the uppermost object definition within
+/// the object definition tree (e.g. the summary object within an
+/// object nesting tree) to the context (a project or project library).
+/// It applies the units, representation context and other context

+///   The following combinatorial restrictions on open shells and geometrical

+///   propositions, to ensure that any domain associated with an open shell is an
+///   orientable manifold.

+///   vertices. The domain of an open shell, if present, contains all edges and
+///   vertices of its faces. 
+/// 
+/// NOTE  Note that this is slightly different from the
+///   definition of a face domain, which includes none of its bounds. For example, a
+///   face domain may exclude an isolated point or line segment. An open shell domain
+///   may not. (See the algorithm for computing below.) 
+///   In the current IFC Release only poly loops
+///   (IfcPolyLoop) are defined for bounds of face bound

+/// 
+/// A one-component image specifies one-byte hexadecimal value representing the intensity of the image. For example, 0xFF is full intensity in hexadecimal (255 in decimal), 0x00 is no intensity (0 in decimal).
+/// A two-component image specifies the intensity in the first
+/// (high) byte and the alpha opacity in the second (low) byte.

One of the constraints has a benchmark of 'GREATERTHANOREQUALTO' whilst the second has a benchmark of 'LESSTHANOREQUALTO'. This means that the constraint must lie between these two bounding values. The relating constraint is instantiated as an objective named as 'Weight Constraint' and qualified as a SPECIFICATION constraint.

+///   a coverage component, currently only given by the alpha component of the texture map (2 or 4 component colour texture) 
+/// 
+/// NOTE: The inherited attribute SurfaceColour is treated as the ambient colour and specifies how much ambient light from light sources this surface shall reflect. Ambient light is omnidirectional and depends only on the number of light sources, not their positions with respect to the surface.
+/// 
+/// NOTE: If the reflectance method, as given by the IfcReflectanceMethodEnum is "GLASS", the transmission factor controls the level of transparency in the glass, In this case the transparency factor is interpreted as transmission factor.
+/// 
+/// NOTE: Both Transparency and TransmissionColour (or factor) are included, the following definitions apply:
+/// 
+/// Transparency is the ratio of the transmitted flux in a solid angle of 2 * PI sr (one hemisphere). It is a simple colour filtration that does not account for refraction. 
+///   Transmission factor of a material is the ratio of transmitted flux in a given solid angle to the transmitted flux of a completely diffuse material with 100% transmission in the same solid angle. It is the portion of light that goes through the material and may be refracted.

+/// Because there is no accepted, universal taxonomy of font properties, matching of properties to font faces must be done carefully. The properties are matched in a well-defined order to ensure that the results of this matching process are as consistent as possible across user agents (assuming that the same library of font faces is presented to each of them).
+/// 
+/// The user agent makes (or
+/// accesses) a database of relevant CSS1
+/// properties of all the fonts of which the UA is aware. The UA may be
+/// aware of a font because it has been installed locally or it has been
+/// previously downloaded over the web. If there are two fonts with
+/// exactly the same properties, one of them is ignored. 
+///   At a given element and for
+/// each character in that element, the UA
+/// assembles the font-properties applicable to that element. Using the
+/// complete set of properties, the UA uses the 'font-family' property to
+/// choose a tentative font family. The remaining properties are tested
+/// against the family according to the matching criteria described with
+/// each property. If there are matches for all the remaining properties,
+/// then that is the matching font face for the given element. 
+///   If there is no matching font
+/// face within the 'font-family' being
+/// processed by step 2, and if there is a next alternative 'font-family'
+/// in the font set, then repeat step 2 with the next alternative
+/// 'font-family'. 
+///   If there is a matching font
+/// face, but it doesn't contain a glyph
+/// for the current character, and if there is a next alternative
+/// 'font-family' in the font sets, then repeat step 2 with the next
+/// alternative 'font-family'.  
+///   If there is no font within
+/// the family selected in 2, then use a
+/// UA-dependent default 'font-family' and repeat step 2, using the best
+/// match that can be obtained within the default font. 
+/// 
+/// (The above algorithm can be
+/// optimized to avoid having to revisit
+/// the CSS1 properties for each character.)
+/// 
+/// The per-property matching rules
+/// from (2) above are as follows:
+/// 
+/// 'font-style' is tried first.
+/// 'italic'
+/// will be satisfied if there is either a face in the UA's font database
+/// labeled with the CSS keyword 'italic' (preferred) or 'oblique'.
+/// Otherwise the values must be matched exactly or font-style will fail. 
+///   'font-variant' is tried
+/// next. 'normal'
+/// matches a font not labeled as 'small-caps'; 'small-caps' matches (1) a
+/// font labeled as 'small-caps', (2) a font in which the small caps are
+/// synthesized, or (3) a font where all lowercase letters are replaced by
+/// upper case letters. A small-caps font may be synthesized by
+/// electronically scaling uppercase letters from a normal font. 
+///   'font-weight' is matched next, it will never fail. (See 'font-weight' below.) 
+///   'font-size' must be matched within a
+/// UA-dependent margin of tolerance. (Typically, sizes for scalable fonts
+/// are rounded to the nearest whole pixel, while the tolerance for
+/// bitmapped fonts could be as large as 20%.) Further computations, are
+/// based on the 'font-size' value that is used, not the one that is specified.
+/// 
+/// The inherited Name attribute is used to define the font name, particularly in cases, where no (list of) font families are provided. 
+/// 
+/// NOTE  Corresponding CSS1 definitions are Font properties ('font-family', 'font-style', 'font-variant',  'font-weight').

+/// is the result of a regularized operation on two solids to create
+/// a new solid. Valid operations are regularized union, regularized
+/// intersection, and regularized difference. For purpose of Boolean
+/// operations, a solid is considered to be a regularized set of
+/// points. The final Boolean result depends upon the operation and
+/// the two operands. In the case of the difference operator the
+/// order of the operands is also significant. The operator can be
+/// either union, intersection or difference. The effect of these
+/// operators is described below:
+/// 
+/// Union on two solids is the new solid that is the
+/// regularization of the set of all points that are in either the
+/// first operand or the second operand or in both.
+/// Intersection on two solids is the new solid that is the
+/// regularization of the set of all points that are in both the
+/// first operand and the second operand.
+/// The result of the difference operation on two solids is the
+/// regularization of the set of all points which are in the first
+/// operand, but not in the second operand.
+/// 
+/// NOTE For example if the first operand is a block and the second operand is a solid cylinder of suitable dimensions and location, the boolean result produced with the difference operator would be a block with a circular hole.

+/// Definition from ISO/CD 10303-42:1992: A closed shell is a shell
+///   of the dimensionality 2 which typically serves as a bound for a region in R3. A
+///   closed shell has no boundary, and has non-zero finite extent. If the shell has
+///   a domain with coordinate space R3, it divides that space into two connected
+///   regions, one finite and the other infinite. In this case, the topological
+///   normal of the shell is defined as being directed from the finite to the
+///   infinite region.  
+///   The shell is represented by a collection of faces. The domain of the
+///   shell, if present, contains all those faces, together with their bounds.
+///   Associated with each face in the shell is a logical value which indicates
+///   whether the face normal agrees with (TRUE) or is opposed to (FALSE) the shell
+///   normal. The logical value can be applied directly as a BOOLEAN attribute of an
+///   oriented face, or be defaulted to TRUE if the shell boundary attribute member
+///   is a face without the orientation attribute.  
+///   The combinatorial restrictions on closed shells and geometrical
+///   restrictions on their domains are designed to ensure that any domain associated
+///   with a closed shell is a closed, orientable manifold. The domain of a closed
+///   shell, if present, is a connected, closed, oriented 2-manifold. It is always
+///   topologically equivalent to an H-fold torus for some H
+///   ³ 0. The number H is referred to as the
+///   surface genus of the shell. If a shell of genus H has a domain within
+///   coordinate space R3, then the finite region of space inside
+///   it is topologically equivalent to a solid ball with H tunnels drilled
+///   through it. 
+///   The Euler equation (7) applies with B=0, because in this case
+///   there are no holes. As in the case of open shells, the surface genus H
+///   may not be known a priori, but shall be an integer ³ 0. Thus a necessary, but not sufficient, condition
+///   for a well-formed closed shell is the following: 
+/// 
+/// In the current IFC Release only poly loops
+///   (IfcPolyLoop) are defined for bounds of face bound
+///   (IfcFaceBound). This will allow for faceted B-rep only.

+/// IfcConstructionResourceType is an abstract generalization of the different resource types used in construction projects, mainly labor, material, equipment and product resource types, plus subcontracted resource types and aggregations such as a crew resource type.

+/// A resource type represents a model of "use of something" and does not necessarily correspond to a specific type of object such as a person or vehicle, but represents possible usages of such objects such as general labor or an equipment fleet.  A resource type can either represent usage in general (consumption attributes defined but no task type assignment) or a task-specific resource type (production attributes defined and having an IfcTask assignment).
+/// 
+/// A construction resource type captures common productivities and cost rates for applying resources to particular task types.
+/// 
+/// HISTORY: New entity in IFC2x4.
+/// 
+/// Composition use definition
+/// Resource types may be decomposed into nested resource types indicating productivities when applying the resource to specific task types using the IfcRelNests relationship where IfcRelNests.RelatingObject refers to the general resource type and IfcRelNests.RelatedObjects refers to one or more task-specific productivities.  For example, an IfcLaborResourceType may be defined for "Carpenter" which may have a nested IfcLaborResourceType for "Carpenter - Wall Framing" and another nested IfcLaborResourceType for "Carpenter - Drywall", each of which may have productivities based according to specific task types (IfcTaskType). 
+/// 
+/// Assignment use definition
+/// Resource types may be assigned to process types (IfcTypeProcess subtypes) using the IfcRelAssignsToProcess relationship as shown in Figure 193.  Such relationship indicates that the resource type applies to the process type for the use indicated (e.g. IfcTaskType.PredefinedType).  Such relationship enables a scenario of placing an IfcProduct of a particular IfcTypeProduct, querying for a set of IfcTypeProcess process types for constructing such product (e.g. IfcTaskTypeEnum.CONSTRUCTION), querying each IfcTypeProcess for a set of IfcTypeResource resource types for carrying out the process, and finally choosing an IfcTypeProcess and IfcTypeResource combination resulting in the shortest time for instantiated IfcTask occurrence(s) and/or lowest-cost for instantiated IfcConstructionResource occurrence(s).

+/// EXAMPLE1 To exchange the net floor area of spaces in
+/// the German region (as IfcSpace), the name might be
+/// 'Netto-Grundfläche' (net floor area), and the method of
+/// measurement might be accordingly 'DIN277-2' (German industry norm

+/// Definition from ISO/CD 10303-46:1992: The fill area style hatching defines a styled pattern of curves for hatching an annotation fill area or a surface.
+/// 
+/// The IfcFillAreaStyleHatching is used to define simple, vector-based hatching patterns, based on styled straight lines. The curve font, color and thickness is given by the HatchLineAppearance, the angle by the HatchLineAngle and the distance to the next hatch line by StartOfNextHatchLine, being either an offset distance or a vector.
+/// 
+/// NOTE  If the hatch pattern involves two (potentially crossing) rows of hatch lines, then two instances of IfcFillAreaStyleHatching should be assigned to the IfcFillAreaStyle. Both share the same (virtual) point of origin of the hatching that is used by the reference hatch line (or the PointOfReferenceHatchLine if there is an offset).
+/// 
+/// For better control of the hatching appearance, when using hatch lines with other fonts then continuous, the PatternStart allows to offset the start of the curve font pattern along the reference hatch line (if not given, the PatternStart is at zero distance from the virtual point of origin). If the reference hatch line does not go through the origin (of the virtual hatching coordinate system), it can be offset by using the PatternStart PointOfReferenceHatchLine.
+/// 
+/// NOTE  The coordinates of the PatternStart and the PointOfReferenceHatchLine are given relative to the assumed 0., 0. virtual point of origin at which the hatch pattern is later positioned by the FillStyleTarget point at IfcAnnotationFillAreaOccurrence. The measure values are given in global drawing length units and apply to the target plot scale for the scale depended representation subcontext.
+/// 
+/// NOTE  The use of PointOfReferenceHatchLine is deprecated.
+/// 
+/// Figure 292 illustrates hatch attributes.
+/// 
+/// Example 1
+/// This example shows simple hatching given by using a curve font "continuous" at HatchLineAppearance.
+/// 
+/// The distance of hatch lines is given by a positive length measure. The
+/// angle (here 45' if measures in degree) is provided by HatchLineAngle.
+/// 
+/// The PatternStart is
+/// set to NIL ($) in this example.  Example 2
+/// This shows hatching from example 1 with using a different curve font at HatchLineAppearance.
+///   The distance of hatch lines is given by a positive
+/// length measure, therefore the font pattern start is at a point at the
+/// next hatch line given by a vector being perpendicular to the point of
+/// origin at the reference hatch line.  The
+/// PatternStart is set to NIL ($) in this example.
+///   Example 3
+/// This example uses hatching from example 2 with a vector to determine the pattern start of the next hatch lines. 
+/// The pattern start is the beginning of the first visual curve font pattern segment at IfcCurveFont.CurveFont.  The PatternStart is set to NIL ($) in this example.
+///   Example 4
+/// This example uses hatching from example 3 where the pattern start is offset from the point of origin at the reference hatch line. That is, the first visible curve font pattern segment now does not start at the point of origin at the reference hatch line.
+/// 
+/// Example 5
+/// This example uses hatching from example 4 where the hatch pattern is shifted against the underlying coordinate system. 
+/// The point that is mapped to the insertion point of the IfcAnnotationFillAreaOccurrence now has an X and Y offset from the start of the reference hatch line. That is, the reference hatch line now does not go through the insertion point of the hatching.    
+///   Example 6
+/// This example shows use of IfcFillAreaStyleHatching attributes for two IfcFillAreaStyleHatching's within one IfcFillAreaStyle. Note that the PatternStart now displaces both the reference hatch line from the point of origin and the start of the curve pattern. This can be used in cases when more than one IfcFillAreaStyleHatching is used in an IfcFillAreaStyle in order to place rows of hatch lines with an offset from each other.

+/// plane within the domain of the face. In other words, it shall be
+/// connected, oriented, finite, non-self-intersecting, and of
+/// surface genus 0.
+/// Faces do not intersect except along their boundaries. Each
+/// edge along the boundary of a face is shared by at most one other
+/// face in the assemblage. The assemblage of edges in the B-rep do
+/// not intersect except at their boundaries (i.e., vertices). The

+/// shall be arcwise connected and shall not self intersect or
+/// overlap within the domain of the edge. The geometry of an edge
+/// shall be consistent with the geometry of the faces of which it
+/// forms a partial bound. The geometry used to define a vertex shall
+/// be consistent with the geometry of the faces and edges of which
+/// it forms a partial bound.
+/// A B-rep is represented by one or more closed shells which
+/// shall be disjoint. One shell, the outer, shall completely enclose
+/// all the other shells and no other shell may enclose a shell. The
+/// facility to define a B-rep with one or more internal voids is

+/// Relationship use definition
+/// On a generic level products can be assigned to processes,
+/// controls, resources, project by using the relationship objects
+/// that refer to the corresponding object:
+/// 
+/// Having a control applied: assigned using
+/// IfcRelAssignsToControl linking the IfcProduct to an
+/// IfcControl
+/// 
+/// An example of this
+/// relationship is the assignment of a performance history to a
+/// distribution element.
+/// 
+/// Being assigned to a process: assigned using
+/// IfcRelAssignsToProcess linking the IfcProduct to an
+/// IfcProcess
+/// 
+/// An example of this
+/// relationship is the assignment of products like wall, slab,
+/// column to a contruction task for construction
+/// planning.
+/// 
+/// Being assigned to a resource: assigned using
+/// IfcRelAssignsToResource linking the IfcProduct to
+/// an IfcResource
+/// 
+/// An example of this
+/// relationship is the assignment of products to a construction
+/// resource that consumes the product.

+/// The IfcProject is used to reference the root of the spatial structure of a building (that serves as the primary project breakdown and is required to be hierarchical). The spatial structure elements are linked together, and to the IfcProject, by using the objectified relationship IfcRelAggregates. The IfcProject references them by its inverse relationship:
+/// 
+/// IfcProject.Decomposes -- it shall be NIL, i.e. the
+/// IfcProject shall not be decomposed into any parts.
+/// IfcProject.IsDecomposedBy -- referencing
+/// (IfcSite || IfcBuilding) by
+/// IfcRelAggregates.RelatingObject. The IfcSite or
+/// IfcBuilding referenced shall be the root of the spatial
+/// structure.
+/// 
+/// The IfcProject is also the context for other information about the construction project such as a work plan. Non-product structures are assigned by their first level object to IfcProject using the IfcRelDeclares relationship.
+/// 
+/// The IfcProject provides the context for spatial elements and the associated products, and for work plans (or other non-product based) descriptions of the construction project. It is handled by two distinct relationship objects as shown in Figure 3.
+/// NOTE   The spatial structure and the schedule structure can be decomposed. For example the IfcBuilding can be decomposed into IfcBuildingStorey's, and the IfcWorkPlan can be decomposed into IfcWorkSchedule's.
+/// NOTE   The products and tasks can be decomposed further. For example the IfcCurtainWall can be decomposed into IfcMember and IfcPlate, the IfcTask can be decomposed into other IfcTask's.
+/// NOTE   The products and tasks can have direct linking relationships. For example the IfcCurtainWall can be assigned to a IfcTask as an input or output for a construction schedule.
+/// NOTE   The anomaly to use the composition structure through IfcRelAggregates for assigning the uppermost spatial container to IfcProject is due to upward compatibility reasons with earlier releases of this standard.

+/// 
+/// When the interference geometry is available it can be passed

+/// coordinate systems of the connecting elements. The

+/// for interference in 3D space, as indicated in e.g. clash
+/// detections.
+/// If the interference geometry is omitted then the interference

+/// referenced instead.
+/// 
+/// The IfcRelSpaceBoundary is defined as an objectified
+/// relationship that handles the element to space relationship by
+/// objectifying the relationship between an element and the space it
+/// bounds. It is given as a one-to-one relationship, but allows each
+/// element (including virutal elements and openings) to define many
+/// such relationship and each space to be defined by many such
+/// relationships.
+/// Space boundaries are always defined as seen from the space. In
+/// general two basic types of space boundaries are
+/// distinguished:
+/// 
+/// 1st level space boundary: defined
+/// as boundaries of the space, not taking into account any change in
+/// building element or spaces on the other side.
+/// 2nd level space boundary: defined
+/// as boundary taking any change in building element or spaces on
+/// the other side into account. It can be further distinguished into
+/// 
+/// 2nd level type A: There is a space
+/// on the other side.
+/// 2nd level type B: There is a
+/// building element on the other side.
+/// 
+/// The exact definition of how space boundaries
+/// are broken down depends on the view definition, more detailed
+/// conventions on how space boundaries are decomposed can only be
+/// given at the domain or application type level.
+/// 
+/// In an architectural or FM related view, a space
+/// boundary is defined totally from inside the space. This is a
+/// 1st level space boundary.
+/// In a thermal view, the decomposition of the space
+/// boundary depends on the material of the providing building
+/// element and the adjacent spaces behind. This is a
+/// 2nd level space boundary.

+/// Differentiation between physical and virtual space boundary is illustrated in Figure 46 and Figure 47.

+/// NOTE The connection geometry, either by a 2D curve or a 3D surface, is used to describe the portion of the "virtual wall" that separates the two spaces. All instances of IfcRelSpaceBoundary given at the adjacent spaces share the same instance of IfcVirtualElement.

+/// IfcResource contains the information needed to represent the costs, schedule, and other impacts from the use of a thing in a process. It is not intended to use IfcResource to model the general properties of the things themselves, while an optional linkage from IfcResource to the things to be used can be specified (specifically, the relationship from subtypes of IfcResource to IfcProduct through the IfcRelAssignsToResource relationship).  
+/// 
+/// There are two basic intended uses of IfcResource. First, if the attributes of the thing are not needed for the purpose of the use of IfcResource, or the types of things are not explicitly modeled in IFC yet, then the linkage between the resource and the thing doesn't have to be instantiated in the system. That is, the attributes of IfcResource (or its subtypes) alone are sufficient to represent the use of the thing as a resource for the purpose of the project.  
+/// 
+/// EXAMPLE: construction equipment such as earth-moving vehicles or tools are not currently modeled within the IFC. For the purpose of estimating and scheduling, these can be represented using subtypes of IfcResource alone.
+///

+/// Definition from IAI: The abstract entity IfcStructuralActivity combines the definition of actions (such as forces, displacements, etc.) and reactions (support reactions, internal forces, deflections, etc.) which are specified by using the basic load definitions from the IfcStructuralLoadResource.
+/// 
+/// The differentiation between actions and reactions is realized by instantiating objects either from subclasses of IfcStructuralAction or IfcStructuralReaction respectively.  They inherit commonly needed attributes from the abstract superclass IfcStructuralActivity, notably the relationship which connects actions or reactions with connections, analysis members, or elements (subtypes of IfcStructuralItem or IfcElement).
+/// 
+/// NOTE  Instances of IfcStructuralActivity which are connected with an IfcElement are subject to agreements outside the scope of this specification.
+/// 
+/// NOTE  The semantics of IfcStructuralActivity are only fully defined
+/// if an activity instance is connected with exactly one structural item.  The inverse attribute
+/// AssignedToStructuralItem can only be empty in incomplete models or in conceptual models
+/// which are not yet ready for analysis.
+/// 
+/// HISTORY: New entity in IFC 2x2.
+/// 
+/// IFC 2x4 change:  Cardinality of attribute
+/// AssignedToStructuralItem relaxed from 1 to 0..1 in order to allow for schema-compliant
+/// incomplete models as well as conceptual models without load—item relationships.
+/// 
+/// Coordinate Systems:
+/// 
+/// The following coordinate systems are distinguished:
+/// 
+/// The so-called global coordinate system is the coordinate system shared by all items and activities which are grouped in a common IfcStructuralAnalysisModel.  This coordinate system is established by an ObjectPlacement.  (This coordinate system is not necessarily the same as the IfcProject's world coordinate system.)
+///   The so-called local coordinate system is a coordinate system local to a structural item (connection or member).  This coordinate system is established by a Representation in conjunction with further use definitions and attributes of subtypes of IfcStructuralItem.
+/// 
+/// Representation items in topology representations are always given within the ObjectPlacement, i.e. in so-called global coordinates (global with respect to the IfcStructuralAnalysisModel to which this activity belongs).
+/// 
+/// Locations of the load objects in the AppliedLoad attribute (if of type IfcStructuralLoadConfiguration) are always given in local coordinates.
+/// 
+/// Directions of the load objects in the AppliedLoad attribute refer to global or local coordinates according to the GlobalOrLocal attribute.
+/// 
+/// The ObjectPlacement and Representation are sometimes not explicitly instantiated; instead they may be implied as described below.  Global and local coordinate systems are then determined in the same way as with explicit placement and representation.
+/// 
+/// Topology Use Definitions:
+///

+/// 
+/// Structural point items
+/// 
+/// The reference point in the representation is the origin of the local coordinate system of the structural item.
+///   The axes of the local coordiante system are either parallel with and directed like the so-called global coordinate axes, or are oriented according to definitions at the respective subtype of IfcStructuralItem.
+/// 
+/// Structural curve items

+/// 
+/// A surface curve swept
+/// area solid is a type of swept area solid which is the result of
+/// sweeping a face along a Directrix lying on a
+/// ReferenceSurface. The orientation of the
+/// SweptArea is related to the direction of the surface
+/// normal.
+/// The
+/// SweptArea is required to be a curve bounded surface lying
+/// in the plane z = 0 and this is swept along the Directrix
+/// in such a way that the origin of the local coordinate system used
+/// to define the SweptArea is on the Directrix and
+/// the local x-axis is in the direction of the normal to the
+/// ReferenceSurface at the current point. The resulting solid
+/// has the property that the cross section of the surface by the
+/// normal plane to the Directrix at any point is a copy of
+/// the SweptArea.
+/// The orientation of
+/// the SweptArea as it sweeps along the Directrix is
+/// precisely defined by a Cartesian Transformation Operator 3D with
+/// attributes:
+/// 
+/// LocalOrigin
+/// as point (0; 0; 0),
+/// Axis1 as
+/// the normal N to the ReferenceSurface at the point of the
+/// Directrix with parameter u.
+/// Axis3 as
+/// the direction of the tangent vector t at the point of the
+/// Directrix with parameter u.
+/// The remaining attributes are defaulted to define a corresponding
+/// transformation matrix T(u), which varies with the
+/// Directrix parameter u.
+/// 
+/// NOTE  The
+/// geometric shape of the solid is not dependent upon the curve
+/// parameterization; the volume depends upon the area swept and the

+/// 
+/// Type use definition
+/// 
+/// IfcTask defines the anticipated or actual occurrence
+///   of any task; common information about task types is handled
+///   by IfcTaskType. The IfcTaskType (if present)
+///   may establish the common type name, usage (or predefined)
+///   type, common set of properties, and common product
+///   assignment using IfcRelAssignsToProduct. The
+///   IfcTaskType is attached using the
+///   IfcRelDefinesByType.RelatingType objectified
+///   relationship and is accessible by the inverse
+///   IsTypedBy attribute. Special type information
+///   relating to a task occurrence is asserted using
+///   IfcTask.ObjectType (inherited from
+///   IfcObject). Examples that may be used include fixed
+///   duration, fixed unit or fixed work. IfcTask can be
+///   aggregated to a task type in order to specify a task
+///   sequence or any time related information, e.g. the duration
+///   of a task. Please see the documentation of
+///   IfcTaskType for further information.
+/// 
+/// Attribute use definition
+/// 
+/// Each occurrence of IfcTask is given a name that is
+///   indicative of its content (IfcRoot.Name). A textual
+///   description of the task may be provided and this may be
+///   further elaborated by a narrative long description
+///   (IfcProcess.LongDescription). A work method may be
+///   declared for the method of work used in carrying out a
+///   task. A task is identified as being either a milestone task
+///   or not. A milestone task is defined by the marker
+///   IsMilestone. and has no duration. A status and
+///   priority for each task may also be set.
+/// 
+/// Property set use definition
+/// 
+/// The property sets relating to IfcTask are defined by
+///   IfcPropertySet and attached by the
+///   IfcRelDefinesByProperties relationship. They are
+///   accessible by the inverse IsDefinedBy relationship.
+///   Such property sets may define task parameters. No property
+///   sets for IfcTask are currently defined by IFC.
+/// 
+/// Connectivity Use Definition
+/// 
+/// The relationship IfcRelSequence is used to indicate
+///   control flow. An IfcTask as a successor to an
+///   IfcTask indicates logical sequence how these tasks
+///   should be performed. IfcTask's can be triggered or
+///   can trigger IfcEvent's, which is also defined
+///   through the relationship IfcRelSequence.
+/// 
+/// Composition use definition
+/// 
+/// IfcTask may be contained within an IfcTask
+///   using the IfcRelNests relationship. An
+///   IfcTask may in turn nest other IfcTask,
+///   IfcProcedure or IfcEvent entities. Such
+///   nesting indicates decomposed level of detail. From IFC2x4
+///   onwards it is required to have a summary task (root of all
+///   tasks), which is used to define a link to the work plan or
+///   work schedule. All subtasks of the summary tasks are then
+///   implicitly linked to this work plan or work schedule.
+///   Please note that the summary task is used for data
+///   organization and not meant to store typical task
+///   information as defined by the user. It is therefore
+///   recommended that the summary task is hidden from the user
+///   to avoid confusion. Please also note that
+///   IfcRelNests is used to show the dependency between
+///   regular tasks and recurring task definitions (please see
+///   the section about time and duration use definitions).
+/// 
+/// As shown in Figure 13, the installation of a number of items of equipment within a
+///   particular space may be the subject of a single task which
+///   is identified as 'fix equipment in space 123'.
+///   IfcTask represents the occurrence of a work
+///   performance of a type of process in a construction plan.
+/// 
+/// Figure 13 — Task visualization
+/// 
+/// A task may nest other tasks as sub-items; the nesting
+///   relationship is modeled by IfcRelNests as shown in Figure 14. For example,
+///   the construction of a stud wall may be designated as a
+///   nesting task named 'install wall #1' including other tasks
+///   such as 'install dry wall', 'install studs', 'wall taping',
+///   and 'erect wall' as sub-processes. A value that indicates
+///   the relative tree view position of the task (in comparison
+///   to the tree view position of other tasks and the task
+///   hierarchy defined by IfcRelNests).
+///   The task order information that is used for viewing
+///   purposes is derived from the order defined by the
+///   IfcRelNests relationship and thus is independent of
+///   the logical task order defined through
+///   IfcRelSequence. The hierarchy and order defined
+///   through IfcRelNests enables to order the tasks in a
+///   tree view or list view structure.
+/// 
+/// Figure 14 — Task nesting relationships
+/// 
+/// Time and duration use definition
+/// 
+/// Compared to previous IFC releases, basic task time
+///   information (scheduled start time, scheduled finish
+///   time, duration) is now directly attached to IfcTask
+///   through the TaskTime attribute. Regular tasks are
+///   defined through IfcTaskTime. Recurring tasks are
+///   defined through IfcTaskTimeRecurring. In case a
+///   regular task is derived from a recurring task both tasks
+///   should be linked together through a IfcRelNests
+///   relationship, where IfcRelNests.IsNestedBy points to
+///   the recurring task and IfcRelNests.Nests points to
+///   all regular tasks that have been derived from the recurring
+///   task.
+/// 
+/// Assignment use definition
+/// 
+/// Occurrences of IfcTask may be assigned to an
+///   IfcWorkControl (either a work plan or a work
+///   schedule) through IfcRelAssignsToControl. From
+///   IFC2x4 onwards it is suggested to use the 'summary task'
+///   (root element of the task hierarchy that is required for
+///   task management purposes) to assign all subtask to a work
+///   plan or work schedule. Resources used by tasks are assigned
+///   by IfcRelAssignsToProcess. Quantities of resources
+///   consumed by the task are dealt with by defining the
+///   IfcElementQuantity for the resource and not at the
+///   instance of IfcTask. Please note that the
+///   IfcRelAssignsTasks relationship class has been
+///   removed in IFC2x4 and is no longer available.
+/// 
+/// An IfcTask may be assigned a Work Breakdown
+///   Structure (WBS) code. A WBS code is dealt with as a
+///   classification of task and is associated to a task
+///   occurrence using the IfcRelAssociatesClassification
+///   relationship class. As well as being to designate the code,
+///   the classification structure of the IFC model also enables
+///   the source of the work breakdown structure classification
+///   to be identified.
+/// 
+/// Constraint use definition
+/// 
+/// Constraints may be applied to a task to indicate fixed task
+///   duration, fixed start or fixed finish (see Figure 15). The relationship
+///   IfcRelAssociatesConstraint is used where
+///   RelatingConstraint points to an IfcMetric and
+///   RelatedObjects includes the IfcTask.
+///   IfcRelAssociatesConstraint.Name identifies the
+///   attribute to be constrained using a period (".") to
+///   dereference; for example, "TaskTime.ScheduleStart" refers
+///   to the ScheduleStart attribute on the
+///   IfcTaskTime entity referenced on the TaskTime
+///   attribute. The following attributes may be constrained:
+/// 
+/// 'TaskTime.ScheduleDuration': Indicate fixed
+///   duration of task with ConstraintGrade=HARD and
+///   Benchmark=EQUALTO such that changes to an assigned
+///   IfcConstructionResource.ResourceTime.ScheduleWork
+///   should impact
+///   IfcConstructionResource.ResourceTime.ScheduleUsage,
+///   and vice-versa.
+/// 
+/// 'TaskTime.ScheduleStart': Indicate constrained
+///   start date with ConstraintGrade=HARD and Benchmark of
+///   EQUALTO, GREATERTHANOREQUALTO, or LESSTHANOREQUALTO to
+///   indicate "must start on", "start no earlier than" or
+///   "start no later than" respectively where
+///   IfcMetric.DataValue indicates the specific
+///   IfcDateTime. Use SOFT constraint having LESSTHAN
+///   benchmark to indicate "start as soon as possible".
+/// 
+/// 'TaskTime.ScheduleFinish': Indicate constrained
+///   finish date with ConstraintGrade=HARD and Benchmark of
+///   EQUALTO, GREATERTHANOREQUALTO, or LESSTHANOREQUALTO to
+///   indicate "must finish on", "finish no earlier than" or
+///   "finish no later than" respectively where
+///   IfcMetric.DateValue indicates the specific
+///   IfcDateTime. Use SOFT constraint having
+///   GREATERTHAN benchmark to indicate "finish as late as
+///   possible".
+/// 
+/// A "manual scheduled task" is indicated with
+///   ConstraintGrade=HARD and Benchmark=EQUALTO for both
+///   TaskTime.ScheduleStart and
+///   TaskTime.ScheduleFinish.
+/// 
+/// Figure 15 — Task constraints
+/// 
+/// Use Definition to represent other activities
+/// 
+/// The use definitions for IfcTask have been generalised to
+///   represent other activities as well, including actitities
+///   that had been defined by own entities in previous IFC
+///   releases. This includes
+/// 
+/// Order actions
+///   Move operations
+/// 
+/// IfcTask represents an order that might be carried
+///   out by a Helpdesk acting the role of interface for the
+///   organization between the facility user and the functional
+///   requirement of fulfilling their needs. The actual task
+///   represented by the IfcTask entity is turning a
+///   request into an order and initiating the action that will
+///   enable the order to be completed. The
+///   IfcProjectOrder or one of its subtypes including
+///   maintenance work order, is related to the IfcTask
+///   using IfcRelAssignsToControl.
+/// 
+/// IfcTask can also be used to describe an activity
+///   that moves people, groups within an organization or
+///   complete organizations together with their associated
+///   furniture and equipment from one place to another. It thus
+///   replaces the previous IFC entity IfcMove. The functionality
+///   is represented in IfcTask as follows:
+/// 
+/// Move from: The place from which actors and their
+///   associated equipment are moving.
+///   Use IfcRelAssignsToProcess where
+///   RelatingProcess points to the task and
+///   RelatedObjects holds the location(s) from which to
+///   move.
+///   Move to: The place to which actors and their
+///   associated equipment are moving.
+///   Use IfcRelAssignsToProduct where
+///   RelatedObjects points to the task(s) and
+///   RelatingProduct points to the location to which to
+///   move.
+///   Punch list: A list of points concerning a move that
+///   require attention.
+///   Use LongDescription or else identify sub-tasks to
+///   track punch list items individually via IfcRelNests.

+/// The IfcAnnotation can provide specific 0D, 1D, and
+///   2D geometric items as representation of the annotation,
+///   offering annotation point, curves, and surfaces.
+/// 
+/// 'Annotation point' is an annotation provided by a
+///   point that has additional semantic. The inherited
+///   attribute ObjectType should be used to capture the
+///   type of point annotation, some predefined values are:
+/// 
+/// 'Survey': A survey point has a set of
+///   cartesian coordinates determined by its location at
+///   point. These coordinates are determined relative to the
+///   coordinates of a reference point, which acts as the
+///   datum for the survey. The difference in elevation of
+///   the survey points enables terrain to be determined.
+/// 
+/// 'Annotation curve' is an annotation provided by a
+///   curve that has additional semantic. The inherited
+///   attribute ObjectType should be used to capture the
+///   type of curve annotation, some predefined values are:
+/// 
+/// 'ContourLine': A line of constant
+///   elevation typically used on geographic maps where the
+///   spacing of lines at constant intervals of elevation may
+///   be used as an indication of slope.
+/// 
+/// 'IsoBar': A line of constant pressure
+///   typically used on weather maps or to show pressure

+/// Local Placement
+/// 
+/// The local placement for any IfcAnnotation is defined

+/// 
+/// If the relative placement is not used, the absolute
+///   placement is defined within the world coordinate system.

+/// Geometric Representations
+/// 
+/// The standard representation of IfcAnnotation is

+/// 
+/// Property Set Use Definition
+/// The property sets relating to the IfcBuildingStorey are
+/// defined by the IfcPropertySet and attached by the
+/// IfcRelDefinesByProperties relationship. It is accessible
+/// by the inverse IsDefinedBy relationship. The following
+/// property set definitions specific to the IfcBuildingStorey
+/// are part of this IFC release:
+/// 
+/// Pset_BuildingStoreyCommon: common property
+/// set for all types of building stories
+/// 
+/// Quantity Use Definition
+/// The quantities relating to the IfcBuildingStorey are
+/// defined by the IfcElementQuantity and attached by the
+/// IfcRelDefinesByProperties relationship. It is accessible
+/// by the inverse IsDefinedBy relationship. The following
+/// base quantities are defined and should be exchanged with the
+/// IfcElementQuantity.Name = 'BaseQuantities'. Other
+/// quantities, being subjected to local standard of measurement, can
+/// be defined with another string value assigned to Name. In
+/// this case a valid value for MethodOfMeasurement has to be
+/// provided.
+/// 
+/// Qto_BuildingStoreyBaseQuantities: base
+/// quantities for all building storey occurrences.
+/// 
+/// Spatial Structure Use Definition
+/// The IfcBuildingStorey is used to build the spatial
+/// structure of a building (that serves as the primary project
+/// breakdown and is required to be hierarchical). The spatial
+/// structure elements are linked together by using the objectified
+/// relationship IfcRelAggregates. The
+/// IfcBuildingStoreyreferences them by its inverse
+/// relationships:
+/// 
+/// IfcBuildingStorey.Decomposes -- referencing
+/// (IfcBuilding || IfcBuildingStorey) by
+/// IfcRelAggregates.RelatingObject, If it refers to another
+/// instance ofIfcBuildingStorey, the referenced
+/// IfcBuildingStorey needs to have a different and higher
+/// CompositionType, i.e. COMPLEX (if the other
+/// IfcBuildingStorey has ELEMENT), or ELEMENT (if the other
+/// IfcBuildingStorey has PARTIAL).
+/// IfcBuildingStorey.IsDecomposedBy -- referencing
+/// (IfcBuildingStorey || IfcSpace) by
+/// IfcRelAggregates.RelatedObjects. If it refers to another
+/// instance ofIfcBuildingStorey, the referenced
+/// IfcBuildingStorey needs to have a different and lower
+/// CompositionType, i.e. ELEMENT (if the other
+/// IfcBuildingStorey has COMPLEX), or PARTIAL (if the other
+/// IfcBuildingStorey has ELEMENT).
+/// 
+/// If there are building elements and/or other elements directly
+/// related to the IfcBuildingStorey (like most building
+/// elements, such as walls, columns, etc.), they are associated with
+/// the IfcBuildingStorey by using the objectified
+/// relationship IfcRelContainedInSpatialStructure. The
+/// IfcBuildingStorey references them by its inverse
+/// relationship:
+/// 
+/// IfcBuildingStorey.ContainsElements -- referencing any
+/// subtype of IfcProduct (with the exception of other spatial
+/// structure element) by
+/// IfcRelContainedInSpatialStructure.RelatedElements.
+/// 
+/// Figure 25 shows the IfcBuildingStorey as part of the
+/// spatial structure. It also serves as the spatial container for
+/// building and other elements.
+/// NOTE Detailed requirements on mandatory element
+/// containment and placement structure relationships are given in
+/// view definitions and implementer agreements.
+/// 
+/// Figure 25 — Building storey composition
+/// 
+/// Elements can also be referenced in an
+/// IfcBuildingStorey, for example, if they span through several
+/// storeys. This is expressed by using the objectified relationship
+/// IfcRelReferencedInSpatialStructure. Systems, such as
+/// building service or electrical distribution systems, zonal
+/// systems, or structural analysis systems, relate to
+/// IfcBuildingStorey by using the objectified relationship
+/// IfcRelServicesBuildings.

+/// 
+/// Geometry Use Definitions
+/// The geometric representation of IfcBuildingStorey is
+/// given by the IfcProductDefinitionShape and
+/// IfcLocalPlacement, allowing multiple geometric
+/// representation.
+/// Local Placement
+/// The local placement for IfcBuildingStorey is defined in
+/// its supertype IfcProduct. It is defined by the
+/// IfcLocalPlacement, which defines the local coordinate
+/// system that is referenced by all geometric representations.
+/// 
+/// The PlacementRelTo relationship of
+/// IfcLocalPlacement shall point (if relative placement is
+/// used) to the IfcSpatialStructureElement of type
+/// IfcBuilding, or of type IfcBuildingStorey (e.g. to
+/// position a building storey relative to a building storey complex,
+/// or a partial building storey to a building storey).
+/// If the relative placement is not used, the absolute placement
+/// is defined within the world coordinate system.
+/// 
+/// Geometric Representations
+/// Currently, the use of a 2D 'FootPrint' representation of type
+/// 'GeometricCurveSet' and a 3D 'Body' representation of type 'Brep'
+/// is supported.
+/// 
+/// NOTE The independent geometric representation of
+/// IfcBuildingStorey may not be required or allowed in
+/// certain view definitions. In those cases only the contained
+/// elements and spaces have an independent geometric
+/// representation.
+/// 
+/// Foot Print Representation
+/// The foot print representation of IfcBuildingStorey is
+/// given by either a single 2D curve (such as IfcPolyline or
+/// IfcCompositeCurve), or by a list of 2D curves (in case of
+/// inner boundaries), if the building storey has an independent
+/// geometric representation.
+/// The representation identifier and type of this geometric
+/// representation of IfcBuildingStorey is:
+/// 
+/// IfcShapeRepresentation.RepresentationIdentifier =
+/// 'FootPrint'
+/// IfcShapeRepresentation.RepresentationType =
+/// 'GeometricCurveSet'
+/// 
+/// Body Representation
+/// The body (or solid model) geometric representation (if the
+/// building storey has an independent geometric representation) of
+/// IfcBuildingStorey is defined using faceted B-Rep
+/// capabilities (with or without voids), based on the
+/// IfcFacetedBrep or on the

+/// of IfcBuildingStorey is:
+/// 
+/// IfcShapeRepresentation.RepresentationIdentifier =
+/// 'Body'
+/// IfcShapeRepresentation.RepresentationType =

+/// Definition from ISO/CD 10303-42:1992: A conic (IfcConic) is a planar curve which could be produced by intersecting a plane with a cone. A conic is defined in terms of its intrinsic geometric properties rather than being described in terms of other geometry. A conic class always has a placement coordinate system defined by a two or three dimensional placement. The parametric representation is defined in terms of this placement coordinate system.
+/// 
+/// NOTE Corresponding ISO 10303 entity: conic, only the following subtypes have been incorporated into IFC 1.0, 1.5 & 2.0: circle as IfcCircle, ellipse as IfcEllipse. The derived attribute Dim has been added at this level and was therefore demoted from the geometric_representation_item. Please refer to ISO/IS 10303-42:1994, p. 38 for the final definition of the formal standard.

+/// 
+/// HISTORY  New entity in IFC2x2.

+/// 
+/// Type use definition
+/// IfcConstructionResource defines the occurrence of any construction resource; common information about construction resource types is handled by IfcConstructionResourceType. The IfcConstructionResourceType (if present) may establish the common type name, common properties, common cost rates, and common productivities applied to specific task types. The IfcConstructionResourceType is attached using the IfcRelDefinesByType.RelatingType objectified relationship and is accessible by the inverse IsTypedBy attribute as shown in Figure 186.
+/// The resource type may provide shared productivity and cost information, allowing tasks and resources to be selected according to lowest cost and/or shortest duration. Given an IfcProduct of a particular IfcTypeProduct type, an IfcTypeProcess may be selected from those assigned to the product type using IfcRelAssignsToProduct, and an IfcTypeResource may be selected from those assigned to the process type using IfcRelAssignsToProcess. Then IfcTask and IfcConstructionResource occurrences may be instantiated from the type definitions, applying productivitity and rate information to assigned quantities to calculate ResourceTime.ScheduleWork. Task durations can then be calculated by dividing ResourceTime.ScheduleWork by ResourceTime.ScheduleUsage.
+/// 
+/// Figure 186 — Construction resource type use
+/// 
+/// Composition use definition
+/// Resources may be decomposed into allocation pools using the IfcRelNests relationship as shown in Figure 187. For example, an IfcLaborResource for "Electrician" may be decomposed into three task-specific IfcLaborResource objects: "Electrical Rough-in", "First Floor Circuits", and "Second Floor Circuits". Both relating and related sides may represent the same ResourceTime.ScheduleUsage quantity (for example, 6 workers time-shared), or the related side may break out ResourceTime.ScheduleUsage quantities for reserved use (for example, 4 workers and 2 workers). 
+/// A common scenario is two nesting levels where the first-level resources have no task assignments; while second-level resources have specific task assignments indicating that the resource is subdivided into allocations for specific tasks. While the model allows unlimited nesting of resources, implementer agreements may restrict to two nesting levels with task assignments specifically at the second level.
+/// 
+/// Figure 187 — Construction resource composition use
+/// 
+/// Declaration use definition
+/// A root-level resource (specifically IfcCrewResource or IfcSubContractResource) is declared within the project by IfcRelDeclares where RelatingContext refers to the single IfcProject and RelatedObjects refers to one or more IfcConstructionResource, and other root-level objects within the project.
+/// 
+/// Assignment use definition
+/// A resource may be assigned to an actor by IfcRelAssignsToActor where RelatingActor refers to an IfcActor and RelatedObjects refers to one or more IfcConstructionResource or other objects. Such relationship indicates the actor responsible for allocating the resource such as partitioning into task-specific allocations, delegating to other actors, and/or scheduling over time. Note that this assignment does not indicate the person or organization performing the work; that is indicated by IfcRelAssignsToResource. The actor responsible for the resource may or may not be the same as any actor(s) performing work.
+/// A resource may be assigned to a control by IfcRelAssignsToControl where RelatingProduct refers to an IfcControl and RelatedObjects refers to one or more IfcConstructionResource or other objects. Most commonly an IfcWorkCalendar is assigned indicating availability of the resource, where such calendar is nested within a base calendar or an IfcWorkPlan which in turn is assigned to the IfcProject.
+/// A resource may be assigned to a group by IfcRelAssignsToGroup where RelatingGroup refers to an IfcGroup and RelatedObjects refers to one or more IfcConstructionResource or other objects. Most commonly an IfcAsset is assigned indicating the asset to be tracked, where such asset is nested within an IfcInventory which in turn is assigned to the IfcProject.
+/// A resource may be assigned to a product by IfcRelAssignsToProduct where RelatingProduct refers to an IfcProduct and RelatedObjects refers to one or more IfcConstructionResource or other objects. Most commonly an IfcElement subtype is assigned indicating the product to be constructed, where such product is connected to a spatial
+/// structure which in turn is aggregated within the IfcProject.
+/// A resource may be assigned to a process by IfcRelAssignsToProcess where RelatingProcess refers to an IfcProcess and RelatedObjects refers to one or more IfcConstructionResource or other objects. Most commonly an IfcTask is assigned indicating the task to be performed by the resource, where such task is nested within a summary task which in turn is assigned to the IfcProject. 
+/// A resource may have assignments of other objects using IfcRelAssignsToResource where RelatingResource refers to the IfcConstructionResource and RelatedObjects refers to one or more objects such as IfcActor or IfcProduct subtypes. This relationship indicates specific objects assigned to fulfill resource usage.

The relationship IfcRelAssociatesConstraint is used where RelatingConstraint points to an IfcMetric and RelatedObjects includes the IfcConstructionResource as shown in Figure 189. IfcRelAssociatesConstraint.Name identifies the attribute to be constrained using a period (".") to dereference; for example, "ResourceTime.ScheduleWork" refers to the ScheduleWork attribute on the IfcResourceTime entity referenced on the ResourceTime attribute. The following attributes may be constrained:
+/// 
+/// 'ResourceTime.ScheduleUsage': Indicate fixed usage (e.g.
+/// simultaneous workers) with ConstraintGrade=HARD and
+/// Benchmark=EQUALTO such that changes to
+/// ResourceTime.ScheduleWork should impact the assigned

+/// Figure 189 — Construction resource constraint use
+/// 
+/// Time series use definition
+/// Time series may be applied to a resource to indicate the break-out of attribute values over time. The relationship IfcRelAssociatesTimeSeries is used where RelatingTimeSeries points to an IfcTimeSeries (either IfcRegularTimeSeries or IfcIrregularTimeSeries) and RelatedObjects includes the IfcConstructionResource as shown in Figure 190. IfcRelAssociatesTimeSeries.Name identifies the attribute to be constrained using a period (".") to dereference; for example, "ResourceTime.ScheduleWork" refers to the ScheduleWork attribute on the IfcResourceTime entity referenced on the ResourceTime attribute. Refer to attribute descriptions on IfcResourceTime for attribute-specific usage.
+/// Each IfcTimeSeriesValue indicates a LIST of values, where the sequence of the value corresponds to the IfcCostValue at IfcConstructionResource.CostRatesConsumed. For example, if CostRatesConsumed has two IfcCostValue items in the LIST, "Standard" and "Overtime", then IfcTimeSeriesValue(IfcDuration('T8H0M0S'),IfcDuration('T2H0M0S')) would indicate 8 hours at Standard rate and 2 hours at Overtime rate. If the list of values at IfcTimeSeriesValue.ListValues is less than the size of CostRatesConsumed, then subsequent values are considered to be zero.

The relationship IfcRelAssociatesDocument may be used to preserve mappings to such document where RelatingDocument points to an IfcDocumentReference and RelatedObjects includes the IfcConstructionResource as shown in Figure 191.
+/// IfcDocumentReference.ItemReference identifies the resource within the scope of the document, such as an integer or guid. The IfcDocumentReference.ReferencedDocument corresponds to the document which is uniquely identified by IfcDocumentInformation.DocumentId and/or IfcDocumentInformation.PublicationLocation.

Examples include project phase codes, CSI codes, takeoff sequence numbers, and cost accounts. The model allows for all classes that are ultimately subtypes of IfcObject to inherit the ability to have one or more instances of IfcClassificationReference to be assigned. Where identification codes are required, the generic IfcRelAssociatesClassification facility should be used.
+/// 
+/// Composition Use Definition
+/// 
+/// An IfcCostItem can nest other instances of IfcCostItem through its relationships to IfcRelNests. This can be used to enable the development of complex groups of costs as may be found in cost schedules through to pages, sections and complete cost schedules.
+/// 
+/// There is always a summary cost item as the root item of the tree representing the cost item nesting. Subsequent instances of IfcCostItem are assigned to the summary cost item using IfcRelNests.  The summary cost item itself is assigned to IfcCostSchedule through the IfcRelAssignsToControl relationship.
+/// 
+/// Figure 157 illustrates a cost item composition used for a cost schedule.  Each line item has a quantity and separate unit costs where IfcCostValue.CostType indicates the category of cost.  The summary item has a hierarchy of costs calculated according to IfcAppliedValueRelationship.ArithmeticOperator, where IfcCostValue.CostType identifies the category to be totalled.  The Tax component has IfcCostValue.CostType set to 'Material' which indicates it is the sum of all nested values of the 'Material' category ($3 x 3000 + $118 x 100 = $20800).  The Subtotal component has IfcCostValue.CostType set to an asterisk ('*') which indicates it is the sum of all nested values of all categories.

+/// Assignment Use Definition
+/// 
+/// An IfcCostItem can be calculated based on quantities from objects through its relationship to IfcRelAssignsToControl.
+/// 
+/// For quantity-based costing, IfcElement, IfcTask, or IfcResource occurrence subtypes may be used.  Multiple elements may be assigned of the same or different types, using IfcPhysicalQuantity entities defined at each object.  Each IfcPhysicalQuantity type must be identical (for example, all values are IfcAreaQuantity) such that they can be added together.
+/// 
+/// For rate-based costing (specifically for IfcCostScheduleTypeEnum.SCHEDULEOFRATES), a single IfcTypeProduct, IfcTypeProcess, or IfcTypeResource subtype may be used to reflect rates for occurrences of such types.  This enables the possibility to generate a quantity-based cost schedule for occurrences based on types with rate-based cost schedules.

+/// IfcMaterialProfileSet: For elements having a constant cross-section, this defines the material profile which may be used to generate the 'Body' representation at occurrences (for parametric definitions not having representation), or for analysis purposes.
+/// IfcMaterialConstituentSet: For elements containing multiple materials, this indicates materials at named aspects.
+/// 
+/// IfcMaterial: For elements comprised of a single material, this indicates the material.
+/// 
+/// The material is attached by the RelatingMaterial attribute on the IfcRelAssociatesMaterial relationship.  It is accessible by the HasAssociations inverse attribute.
+/// 
+/// Representation Use Definition
+/// The following shape representations are supported for subtypes of IfcDistributionFlowElementType, distinguished by IfcShapeRepresentation.RepresentationIdentifier:
+/// 
+/// 'Axis': Represents the 3D flow path of the item having IfcShapeRepresentation.RepresentationType of 'Curve3D' and containing a single IfcBoundedCurve subtype such as IfcPolyline, IfcTrimmedCurve, or IfcCompositeCurve.  For elements containing directional ports (IfcDistributionPort with FlowDirection of SOURCE or SINK), the direction of the curve indicates direction of flow where a SINK port is positioned at the start of the curve and a SOURCE port is positioned at the end of the curve.  This representation is most applicable to flow segment types (pipes, ducts, cables), however may be used at other elements to define a primary flow path if applicable. 
+/// 
+/// 'Footprint': Represents the 2D footprint outline of the item having IfcShapeRepresentation.RepresentationType of 'GeometricCurveSet' and containing a single IfcGeometricCurveSet consisting of one or more IfcCurve subtypes such as IfcPolyline, IfcTrimmedCurve, IfcCompositeCurve, or IfcCircle.
+/// 
+/// 'Body': Represents the 3D shape of the item having IfcShapeRepresentation.RepresentationType of 'SurfaceModel', 'SolidModel', or any solid model specializations including 'Brep', 'AdvancedBrep', 'SweptSolid', 'AdvancedSweptSolid', 'CSG', 'Clipping', or 'SectionedSpine').
+/// 
+/// 'Clearance': Represents the 3D clearance volume of the item having RepresentationType of 'Surface3D'.  Such clearance region indicates space that should not intersect with the 'Body' representation between element occurrences, though may intersect with the 'Clearance' representation of other element occurrences.  The particular use of clearance space may be for safety, maintenance, or other purpose.
+/// 
+/// 'Lighting': Represents the light emission of the item having IfcShapeRepresentation.RepresentationType of 'LightSource' and containing one or more IfcLightSource subtypes.  This representation is most applicable to lamps and light fixtures, however may be used at other elements that emit light.
+/// 
+/// If an element type is defined parametrically (such as a flow segment type defining common material profile but no particular length or path), then no representations shall be asserted at the type.
+/// 
+/// NOTE: The product representations are defined as representation maps (at the level of the supertype IfcTypeProduct, which get assigned by an element occurrence instance through the IfcShapeRepresentation.Item[1] being an IfcMappedItem.

+/// 
+/// Geometry use definitions
+/// The IfcDoorLiningProperties does not hold its own
+/// geometric representation. However it defines parameters which can
+/// be used to create the shape of the door style (which is inserted
+/// by the IfcDoor into the spatial context of the
+/// project) as shown in Figure 172.
+/// The parameters of the IfcDoorLiningProperties define a
+/// standard door lining, including (if given) a threshold and a
+/// transom. The outer boundary of the lining is determined by the
+/// occurrence parameter assigned to the IfcDoor, which
+/// inserts the IfcDoorStyle.
+/// 
+/// The lining is applied to the left,
+/// right and upper side of the opening reveal. The parameters are:
+/// 
+/// LiningDepth, if omited, equal to
+/// wall thickness - this only takes effect if a value for
+/// LiningThickness is given. If both parameters are not
+/// given, then there is no lining.
+/// LiningThickness
+/// LiningToPanelOffsetX
+/// LiningToPanelOffsetY
+/// 
+/// NOTE Parameters added in
+/// IFC2x4.
+/// 
+/// The lining can only cover part of
+/// the opening reveal.
+/// 
+/// LiningOffset : given if lining edge has an offset to
+/// the x axis of the local placement.
+/// 
+/// NOTE In addition to theLiningOffset,
+/// the local placement of the IfcDoor can already have an
+/// offset to the wall edge and thereby shift the lining along the y
+/// axis. The actual position of the lining is calculated from the
+/// origin of the local placement along the positive y axis with the
+/// distance given by LiningOffset.
+/// 
+/// The lining may include a casing,
+/// which covers part of the wall faces around the opening. The
+/// casing covers the left, right and upper side of the lining on
+/// both sides of the wall. The parameters are:
+/// 
+/// CasingDepth
+/// CasingThickness
+/// 
+/// The lining may include a threshold,
+/// which covers the bottom side of the opening. The parameters are:
+/// 
+/// ThresholdDepth
+/// if omited, equal to wall thickness - this
+/// only takes effect if a value for ThresholdThickness is
+/// given. If both parameters are not given, then there is no
+/// threshold.
+/// ThresholdThickness
+/// ThresholdOffset (not shown in figure): given, if the
+/// threshold edge has an offset to the x axis of the local
+/// placement.
+/// 
+/// The lining may have a transom which
+/// separates the door panel from a window panel. The transom, if
+/// given, is defined by:
+/// 
+/// TransomOffset : a parallel edge to the x axis of the
+/// local placement
+/// TransomThickness
+/// 
+/// The depth of the transom is identical to the depth of the
+/// lining and not given as separate parameter.
+/// 
+/// Figure 172 — Door lining properties
+/// 
+/// NOTE LiningDepth describes the length of the lining along the reveal of the door opening. It can be given by an absolute value if the door lining has a specific depth depending on the door style. However often it is equal to the wall thickness. If the same door style is used (like the same type of single swing door), but inserted into different walls with different thicknesses, it would be necessary to create a special door style for each wall thickness. Therefore several CAD systems allow to set the value to "automatically aligned" to wall thickness. This should be exchanged by leaving the optional attribute LiningDepth unassigned. The same agreement applies to ThresholdDepth.

+/// 
+/// HISTORY  New entity in IFC2x4
+/// 
+/// Use definitions
+/// 
+/// IfcEvent is used to capture information about
+///   particular things that happen or that may happen.
+///   Particularly used in work plans (or process maps) they
+///   identify e.g. a point at which a message containing
+///   information may be issued or at which a rule or constraint
+///   is invoked.
+/// 
+/// Type use definition
+/// 
+/// IfcEvent defines the anticipated or actual occurrence of
+///   any event; common information about event types is handled
+///   by IfcEventType. The IfcEventType (if present) may
+///   establish the common type name, usage (or predefined) type,
+///   common set of properties, and common product assignment
+///   using IfcRelAssignsToProduct. The IfcEventType is attached
+///   using the IfcRelDefinesByType.RelatingType objectified
+///   relationship and is accessible by the inverse IsTypedBy
+///   attribute.
+/// 
+/// Property set use definition
+/// 
+/// The property sets relating to IfcEvent are defined by
+///   IfcPropertySet and attached by the
+///   IfcRelDefinesByProperties relationship. They are accessible
+///   by the inverse IsDefinedBy relationship. Such property sets
+///   may define event parameters. No property sets for IfcEvent
+///   are currently defined by IFC.
+/// 
+/// Connectivity use definition
+/// 
+/// The relationship IfcRelSequence is used to indicate control
+///   flow. An IfcEvent as a predecessor
+///   (IfcRelSequence.RelatingProcess) indicates that the
+///   succeeding process (typically IfcProcedure or IfcTask) is
+///   triggered in response to the event. An IfcEvent as a
+///   successor (IfcRelSequence.RelatedProcess) indicates that
+///   the completion of the preceeding process causes the event
+///   to be triggered. As events have zero duration, the
+///   IfcRelSequence.SequenceType attribute has no effect on an
+///   IfcEvent but still applies to the opposite end of the
+///   relationship if IfcTask is used.
+/// 
+/// Composition use definition
+/// 
+/// IfcEvent may be contained within an IfcTask using the
+///   IfcRelNests relationship. The event is considered active
+///   during the time period of the enclosing task (including any
+///   assigned IfcWorkCalendar); that is such event may be
+///   triggered within the task time period but not outside of
+///   it. As an IfcEvent is considered to be atomic, no use is
+///   anticipated for nesting processes inside the event.
+/// 
+/// Assignment use definition
+/// 
+/// An IfcEvent may be assigned to an IfcWorkCalendar to
+///   indicate times when such event is active using
+///   IfcRelAssignsToControl; otherwise the effective calendar is
+///   determined by the nearest IfcProcess ancestor with a
+///   calendar assigned.
+/// 
+/// For building operation scenarios, IfcEvent may be assigned
+///   to a product (IfcElement subtype) using
+///   IfcRelAssignsToProduct to indicate a specific product
+///   occurrence that sources the event. For example, an
+///   IfcSensor for a motion sensor may have a "Motion Sensed"
+///   event. If the IfcEvent is defined by an IfcEventType and
+///   the IfcEventType is assigned to a product type (using
+///   IfcRelAssignsToProduct), then the IfcEvent must be assigned
+///   to one or more occurrences of the specified product type
+///   using IfcRelAssignsToProduct.

+/// its supertype IfcProduct. It is defined by the
+/// IfcLocalPlacement, which defines the local coordinate
+/// system that is referenced by all geometric representations.
+/// 
+/// The PlacementRelTo relationship of
+/// IfcLocalPlacement shall point (if given) to the local
+/// placement of the master IfcElement (its relevant
+/// subtypes), which is associated to the IfcFeatureElement by
+/// the appropriate relationship object.
+/// If the relative placement is not used, the absolute placement
+/// is defined within the world coordinate system.
+/// 
+/// Geometric Representations
+/// Any IfcFeatureElement can be represented by one or
+/// several geometric representations. A detailed specification is
+/// introduced at the level of subtypes. Only the general
+/// representation identifier 'Box' with representation type
+/// 'BoundingBox', and representation identifier 'Body' with
+/// representation type 'Brep' are defined here.
+/// Box Representation
+/// Any IfcFeatureElement may be represented as a bounding
+/// box, which shows the maximum extend of the body within the
+/// coordinated system established by the IfcLocalPlacement.
+/// The bounding box representation is the simplest geometric
+/// representation available. The following attribute values for the
+/// IfcShapeRepresentation holding this geometric
+/// representation shall be used:
+/// 
+/// RepresentationIdentifier : 'Box'
+/// RepresentationType : 'BoundingBox'
+/// 
+/// Body Representation
+/// The body representation of any IfcFeatureElement can
+/// have the following representation types: 'Brep'. Other
+/// representation types might be specified at the level of
+/// subtypes.
+/// Brep Representation Type
+/// Any IfcFeatureElement (so far no further constraints
+/// are defined at the level of its subtypes) may be represented as a
+/// single or multiple Boundary Representation elements (which are
+/// restricted to faceted Brep with or without voids). The Brep
+/// representation allows for the representation of complex element
+/// shape. The following attribute values for the
+/// IfcShapeRepresentation holding this geometric
+/// representation shall be used:
+/// 
+/// RepresentationIdentifier : 'Body'

+/// Geometry Use Definitions:
+/// The geometric representation of IfcFurnishingElement is
+/// given by the IfcProductDefinitionShape and
+/// IfcLocalPlacement allowing multiple geometric
+/// representation.
+/// Local Placement
+/// The local placement for IfcFurnishingElement is defined
+/// in its supertype IfcProduct. It is defined by the
+/// IfcLocalPlacement, which defines the local coordinate
+/// system that is referenced by all geometric representations.
+/// 
+/// The PlacementRelTo relationship of
+/// IfcLocalPlacement shall point (if given) to the local
+/// placement of the same IfcSpatialStructureElement , which
+/// is used in the ContainedInStructure inverse attribute, or
+/// to a spatial structure element at a higher level, referenced by
+/// that.
+/// If the relative placement is not used, the absolute placement
+/// is defined within the world coordinate system.
+/// 
+/// Geometric Representations
+/// Any IfcFurnishingElement can be represented by one or
+/// several geometric representations. This includes the general
+/// representation types 'BoundingBox', 'GeometricCurveSet',
+/// 'SurfaceModel', 'Brep', and 'MappedRepresentation' being defined
+/// here.
+/// Bounding Box Representation
+/// Any IfcFurnishingElement may be represented as a
+/// bounding box, which shows the maximum extend of the body within
+/// the coordinated system established by the
+/// IfcLocalPlacement. The bounding box representation is the
+/// simplest geometric representation available. The following
+/// attribute values for the IfcShapeRepresentation holding
+/// this geometric representation shall be used:
+/// 
+/// RepresentationIdentifier : 'Box'
+/// RepresentationType : 'BoundingBox'
+/// 
+/// Foot Print Representation
+/// The foot print representation of IfcFurnishingElement
+/// is given by either a single or multiple 2D points and curves. The
+/// representation identifier and type of this geometric
+/// representation are:
+/// 
+/// IfcShapeRepresentation.RepresentationIdentifier =
+/// 'FootPrint'
+/// IfcShapeRepresentation.RepresentationType =
+/// 'GeometricCurveSet'
+/// 
+/// SurfaceModel Representation
+/// Any IfcFurnishingElement (so far no further constraints
+/// are defined at the level of its subtypes) may be represented as a
+/// single or multiple surface models, based on either shell or face
+/// based models. In some cases it may be useful to also expose a
+/// simple representation as a bounding box representation of the
+/// same complex shape. The representation identifier and type of
+/// this geometric representation are:
+/// 
+/// IfcShapeRepresentation.RepresentationIdentifier =
+/// 'Body'
+/// IfcShapeRepresentation.RepresentationType =
+/// 'SurfaceModel'
+/// 
+/// Brep Representation
+/// Any IfcFurnishingElement (so far no further constraints
+/// are defined at the level of its subtypes) may be represented as a
+/// single or multiple Boundary Representation elements (which are
+/// restricted to faceted Brep with or without voids). The Brep
+/// representation allows for the representation of complex element
+/// shape. In some cases it may be useful to also expose a simple
+/// representation as a bounding box representation of the same
+/// complex shape. The representation identifier and type of this
+/// geometric representation are:
+/// 
+/// IfcShapeRepresentation.RepresentationIdentifier =
+/// 'Body'
+/// IfcShapeRepresentation.RepresentationType =
+/// 'Brep'
+/// 
+/// MappedRepresentation
+/// The IfcMappedItem should always be used in appropriate
+/// cases as it allows for reusing the geometry definition of the
+/// furnishing type for all occurrences of the same type. The
+/// representation identifier and type of this geometric
+/// representation are:

+/// HISTORY: New Entity in IFC Release 2.0.  Base type and documentation extended in IFC 2x4.
+/// 
+/// IFC2x4 CHANGE: The attribute Skillset has been deleted; use LongDescription to describe the skillset.
+/// 
+/// The purpose of an IfcLaborResource is to identify a skillset that may be required or used. The skillset identified may be (for instance) chargehand, foreman, labourer, plumbers mate etc. and provides a designation of a particular level of skill. It can be used to identify the generic type of labor resource that is required for a purpose without having to be specific about the actor (person or organization) providing the resource occurrence. It may be particularly useful when creating an overall plan for a process or processes. For instance, within maintenance or work planning there may be a known task that needs to be done which is planned to require a 'chargehand pipe fitter'. There may be several such labor resources available and so the need to identify which will be used is not necessary at the planning stage.
+/// 
+/// At a later stage, individual actors can be determined for the labor resources. This is achieved through specifiying the actor through IfcActor. The actor is then identified as the labour resource occurrence through the IfcRelAssignsToResource.RelatedResource attribute. The IfcLaborResource provides the IfcRelAssignsToResource.RelatingResource attribute. 
+/// 
+/// Use definitions for composition, assignment, constraints, time series, and baselines are described at the base type IfcConstructionResource.
+/// 
+/// Type use definition
+/// IfcLaborResource defines the occurrence of any labor resource; common information about labor resource types is handled by IfcLaborResourceType.  The IfcLaborResourceType (if present) may establish the common type name, common properties, common productivities for various task types using IfcRelAssignsToProcess.  The IfcLaborResourceType is attached using the IfcRelDefinesByType.RelatingType objectified relationship and is accessible by the inverse IsTypedBy attribute.
+/// 
+/// Quantity use definition
+/// The quantities relating to the IfcLaborResource are defined by IfcElementQuantity and attached by the IfcRelDefinesByProperties relationship. It is accessible by the inverse IsDefinedBy relationship. The following base quantities are defined and should be exchanged with the IfcElementQuantity.Name = 'BaseQuantities'. Other quantities can be defined being subjected to local standard of measurement with another string value assigned to Name and a value provided for MethodOfMeasurement.
+/// 
+/// Qto_LaborResourceBaseQuantities: base quantities for all labor resources.
+/// 
+/// Assignment use definition
+/// In addition to assignments specified at the base class IfcConstructionResource, a labor resource may have assignments of its own using IfcRelAssignsToResource where RelatingResource refers to the IfcLaborResource and RelatedObjects contains one or more IfcActor subtypes as shown in Figure 194.  Such relationship indicates the specific people used as input for the resource.  Such actors are nested according to organizational structure with the root organization assigned to the IfcProject.

+/// IfcMember. If the same property is assigned to the
+/// IfcMemberType and the IfcMember being an occurrence
+/// of the IfcMemberType, then the occurrence property
+/// overrides the type property.
+/// 
+/// Pset_MemberCommon: common property set for all
+/// member types.
+/// 
+/// Profile Use Definition:
+/// The shared profile definition is defined by assigning an

+/// The IfcMaterialProfile refers to the subtype of

+/// occurrence, if used. It is only applicable if the
+/// IfcMemberType has only occurrences of type
+/// IfcMemberStandardCase (see definition of
+/// IfcMemberStandardCase for further information).
+/// NOTE The attribute ProfileName of the
+/// IfcProfileDef subtype, referenced in
+/// IfcMaterialProfile should contain a standardized profile
+/// name according to local standards. However, an additional
+/// geometric representation of the profile is necessary (e.g. as
+/// IfcExtrudedAreaSolid). An importing application is allowed
+/// to check for the existence of the profile name: in case of
+/// identifying it as a standardized name, the corresponding profile
+/// geometry and possibly other cross sectional properties can be
+/// read from a library. Otherwise the geometric representation and
+/// possible non geometric IfcProfileProperties have to be
+/// used.
+/// Geometry Use Definition:
+/// The IfcMemberType may define the shared geometric
+/// representation for all member occurrences. The
+/// RepresentationMaps attribute refers to a list of
+/// IfcRepresentationMap's, that allow for multiple geometric
+/// representations (e.g. with IfcShaperepresentation's having

+/// occurrences of type IfcMember (See geometric use
+/// definition of IfcMember for further information).
+/// NOTE If the IfcMemberType has an
+/// associated IfcMaterialProfileSet, then no shared geometric
+/// representation shall be provided.

+/// equal to the thickness of the element;
+/// a recess or niche, where the thickness of the recess is
+/// smaller than the thickness of the element.
+/// 
+/// The attribute PredefinedType should be used to capture
+/// the differences,
+/// 
+/// the attribute is set to OPENING for an opening or

+/// HISTORY New entity in
+/// IFC Release 1.0
+/// IFC2x CHANGE The intermediate
+/// ABSTRACT supertypes IfcFeatureElement and
+/// IfcFeatureSubtraction have been added.
+/// IFC2x4 CHANGE The attribute
+/// PredefinedType has been added at the end of attribute
+/// list.
+/// Property Set Use Definition:
+/// The property sets relating to the IfcOpeningElement are
+/// defined by the IfcPropertySet and attached by the
+/// IfcRelDefinesByProperties relationship. It is accessible
+/// by the inverse IsDefinedBy relationship. The following
+/// property set definitions specific to the IfcOpeningElement
+/// are part of this IFC release:
+/// 
+/// Pset_OpeningElementCommon: common property
+/// set for all opening occurrences
+/// 
+/// Quantity Use Definition:
+/// The quantities relating to the IfcOpeningElement are
+/// defined by the IfcElementQuantity and attached by the
+/// IfcRelDefinesByProperties relationship. It is accessible
+/// by the inverse IsDefinedBy relationship. The following
+/// base quantities are defined and should be exchanged with the
+/// IfcElementQuantity.Name = 'BaseQuantities'. Other
+/// quantities, being subjected to local standard of measurement, can
+/// be defined with another string value assigned to Name. In
+/// this case a valid value for MethodOfMeasurement has to be
+/// provided.
+/// 
+/// Qto_OpeningElementBaseQuantities: base
+/// quantities for all opening occurrences.
+/// 
+/// Containment Use Definition
+/// The IfcOpeningElement shall not participate in the
+/// containment relationship, i.e. it is not linked directly to the
+/// spatial structure of the project. It has a mandatory
+/// VoidsElements inverse relationship pointing to the
+/// IfcElement that is contained in the spatial structure.
+/// 
+/// The inverse relationship ContainedInStructure shall be
+/// NIL.
+/// 
+/// NOTE See IfcRelVoidsElement for a

+/// relationship.
+/// Geometry Use Definitions
+/// The geometric representation of IfcOpeningElement is
+/// given by the IfcProductDefinitionShape and
+/// IfcLocalPlacement allowing multiple geometric
+/// representations.
+/// Local Placement
+/// The local placement for IfcOpeningElement is defined in
+/// its supertype IfcProduct. It is defined by the
+/// IfcLocalPlacement, which defines the local coordinate
+/// system that is referenced by all geometric representations.
+/// 
+/// The PlacementRelTo relationship of

+/// the same element, which is voided by the opening, i.e. referred
+/// to by VoidsElement.RelatingBuildingElement.
+/// 
+/// Geometric Representation
+/// Currently, the 'Body', and 'Box' representations are

+/// element), e.g. for wall openings, or vertically (i.e. in the
+/// extrusion direction of the voided element), e.g., for floor
+/// openings. If multiple instances of IfcExtrudedAreaSolid
+/// are used, the extrusion direction of each extrusion should be
+/// equal.
+/// 
+/// NOTE In case of non-parallel jambs, the shape

+/// 
+/// Type use definition
+/// 
+/// IfcProcedure defines the anticipated or actual
+///   occurrence of any procedure; common information about

+///   IfcProcedureType (if present) may establish the
+///   common type name, usage (or predefined) type, common nested
+///   procedures (using IfcRelNests), common set of
+///   properties, and common product assignment using
+///   IfcRelAssignsToProduct. The IfcProcedureType
+///   is attached using the
+///   IfcRelDefinesByType.RelatingType objectified
+///   relationship and is accessible by the inverse
+///   IsTypedBy attribute.
+/// 
+/// Property set use definition
+/// 
+/// The property sets relating to IfcProcedure are
+///   defined by IfcPropertySet and attached by the
+///   IfcRelDefinesByProperties relationship. They are
+///   accessible by the inverse IsDefinedBy relationship.
+///   Such property sets may define procedure parameters. No
+///   property sets for IfcProcedure are currently defined
+///   by IFC.
+/// 
+/// Connectivity use definition
+/// 
+/// The relationship IfcRelSequence is used to indicate
+///   control flow. An IfcProcedure as a successor to an
+///   IfcEvent indicates that the procedure should be
+///   performed in response to the event. An IfcProcedure
+///   as a predecessor to an IfcEvent indicates that the
+///   event should be trigerred following the procedure. As
+///   procedures have arbitrary duration, the
+///   IfcRelSequence.SequenceType attribute has no effect
+///   on an IfcProcedure but still applies to the opposite
+///   end of the relationship if IfcTask is used.
+/// 
+/// Composition use definition
+/// 
+/// IfcProcedure may be contained within an
+///   IfcTask or IfcProcedure using the
+///   IfcRelNests relationship. An IfcProcedure may
+///   in turn nest other IfcProcedure or IfcEvent
+///   entities. Such nesting indicates decomposed level of
+///   detail.
+/// 
+/// Note that a particular type of IfcProcedure is a
+///   caution, warning or other form of advisory note. Typically,
+///   it is anticipated that such a procedure would be assigned
+///   to the specific IfcProcess for which it gives advice
+///   using IfcRelAssignsToProcess.
+/// 
+/// Assignment use definition
+/// 
+/// An IfcProcedure may be assigned to an
+///   IfcWorkCalendar to indicate times when such
+///   procedure may be performed using
+///   IfcRelAssignsToControl; otherwise the effective
+///   calendar is determined by the nearest IfcProcess
+///   ancestor with a calendar assigned. Advisory notes should be
+///   assigned to the specific IfcProcess for which it
+///   gives advice using IfcRelAssignsToProcess.
+/// 
+/// For building operation scenarios, IfcProcedure may
+///   be assigned to a product (IfcElement subtype) using
+///   IfcRelAssignsToProduct to indicate a specific
+///   product occurrence that performs the procedure. For
+///   example, an IfcActuator may have a "Close"
+///   procedure. If the IfcProcedure is defined by an
+///   IfcProcedureType and the IfcProcedureType is
+///   assigned to a product type (using
+///   IfcRelAssignsToProduct), then the
+///   IfcProcedure must be assigned to one or more
+///   occurrences of the specified product type using
+///   IfcRelAssignsToProduct.
+/// 
+/// As shown in Figure 12, IfcProcedure does not restrict anything but
+///   describes specific steps of how something should happen.
+///   While a procedure does control/restrict in the sense of
+///   indicating "this is how the task should be performed" by
+///   nature of describing inner detail, this is not different than
+///   parts of a product indicating "this is how the parts should
+///   be assembled". Consequently, it doesn't restrict the outer

+/// Pset_ProjectOrderMoveOrder (MOVEORDER) 
+/// Pset_ProjectOrderPurchaseOrder (PURCHASEORDER) 
+/// Pset_ProjectOrderWorkOrder (WORKORDER) 
+/// 
+/// Declaration Use Definition 
+/// The IfcProjectOrder may be declared within the project using the IfcRelDeclares relationship where RelatingContext refers to the single IfcProject and RelatedDefinitions contains the IfcProjectOrder.  Alternatively, if the IfcProjectOrder is aggregated within an IfcWorkPlan, then it shall not have a direct declaration relationship (whereas the containing work plan may have a declaration relationship). 
+/// 
+/// Composition Use Definition 
+/// As shown in Figure 160, an IfcProjectOrder may be aggregated into components using IfcRelAggregates where RelatingObject refers to the enclosing IfcProjectOrder and RelatedObjects contains one or more components.  Aggregation use is defined for the following predefined types:
+/// 
+/// (All Types): May contain IfcCostSchedule components.  A cost schedule may indicate costs and quantities where the cost schedule type may designate whether rates and/or quantities are estimated or final.  Such cost schedule may have assigned cost items indicating detail, where each cost item may have assigned products, processes, or resources. 
+/// WORKORDER: May contain IfcWorkSchedule components.  A work schedule may indicate tasks and scheduled times where the work schedule type may designate whether tasks and/or times are planned or actual.  Such work schedule may have assigned tasks indicating detail, where tasks may be assigned to products and may have assigned resources. 
+/// 
+/// The IfcProjectOrder may be nested into sub-items using IfcRelNests where RelatingObject refers to the enclosing IfcProjectOrder and RelatedObjects contains one or more sub-items.  Nesting use is defined for the following predefined types:
+/// 
+/// WORKORDER: May contain IfcProjectOrder sub-items having PredefinedType CHANGEORDER.  A work order may be nested into change orders to indicate contract ammendment, in order of issue. 
+/// 
+/// Figure 161 — Project order composition
+/// 
+/// Assignment Use Definition 
+/// As shown in Figure 161, an IfcProjectOrder may be assigned to the following entities using relationships as indicated: 
+/// 
+/// IfcActor (IfcRelAssignsToActor): Organization issuing the order such as an owner or contractor. 
+/// 
+/// The IfcProjectOrder may have assignments of its own using the IfcRelAssignsToControl relationship where RelatingControl refers to the IfcProjectOrder and RelatedObjects contains one or more objects of the following types:  
+/// IfcActor: Organization(s) contracted to fulfill the order, typically a single contractor, subcontractor, or supplier.
+/// 
+/// Figure 162 — Project order assignment
+/// 
+/// Approval Use Definition 
+/// Approvals may be associated to indicate the status of acceptance or rejection using the IfcRelAssociatesApproval relationship where RelatingApproval refers to an IfcApproval and RelatedObjects contains the IfcProjectOrder.  Approvals may be split into sub-approvals using IfcApprovalRelationship to track approval status separately for each party where RelatingApproval refers to the higher-level approval and RelatedApprovals contains one or more lower-level approvals.

+/// Local Placement
+/// The local placement for IfcOpeningRecess is defined in

+/// 
+/// Solid: IfcExtrudedAreaSolid is required.
+/// Profile: IfcRectangleProfileDef,
+/// IfcCircleProfileDef and IfcArbitraryClosedProfileDef
+/// shall be supported.
+/// Extrusion: The profile shall be extruded horizontally
+/// (that is, perpendicular to the extrusion direction of the modified
+/// element), such as for wall projections, or vertically (that is, in the
+/// extrusion direction of the projected element), such as for floor
+/// projections.
+/// 
+/// As shown in Figure 38, the following interpretation of dimension parameter applies for
+/// rectangular projection:
+/// 
+/// IfcRectangleProfileDef.YDim interpreted as projection
+/// width
+/// IfcRectangleProfileDef.XDim interpreted as projection
+/// height
+/// IfcExtrudedAreaSolid.Depth is interpreted as projection

+/// Definition from ISO 6707-1:1989: Area where construction

+/// A site is a defined area of land, possibly
+/// covered with water, on which the project construction is to be
+/// completed. A site may be used to erect building(s) or other AEC
+/// products.
+/// A site (IfcSite) may include a definition of the single
+/// geographic reference point for this site (global position using
+/// WGS84 with Longitude, Latitude and Elevation).
+/// The precision is provided up to millionth of a second and it
+/// provides an absolute placement in relation to the real world as
+/// used in exchange with geospational information systems. If
+/// asserted, the Longitude, Latitude and
+/// Elevation establish the point in WGS84 where the point
+/// 0.,0.,0. of the LocalPlacement of IfcSite is
+/// situated.
+/// The geometrical placement of the site, defined by the
+/// IfcLocalPlacement, shall be always relative to the spatial
+/// structure element, in which this site is included, or absolute,
+/// i.e. to the world coordinate system, as established by the
+/// geometric representation context of the project. The world
+/// coordinate system, established at the
+/// IfcProject.RepresentationContexts, may include a definition
+/// of the true north within the XY plane of the world coordinate
+/// system, if provided, it can be obtained at
+/// IfcGeometricRepresentationContext.TrueNorth.
+/// A project may span over several connected or disconnected sites.
+/// Therefore site complex provides for a collection of sites included
+/// in a project. A site can also be decomposed in parts, where each
+/// part defines a site section. This is defined by the composition
+/// type attribute of the supertype IfcSpatialStructureElements
+/// which is interpreted as follow:
+/// 
+/// COMPLEX = site complex
+/// ELEMENT = site
+/// PARTIAL = site section
+/// 
+/// HISTORY  New entity in IFC Release 1.0.
+/// 
+/// Property Set Use Definition
+/// The property sets relating to the IfcSite are defined by
+/// the IfcPropertySet and attached by the
+/// IfcRelDefinesByProperties relationship. It is accessible by
+/// the inverse IsDefinedBy relationship. The following property
+/// set definitions specific to the IfcSite are part of this IFC
+/// release:
+/// 
+/// Pset_SiteCommon: common property set for all
+/// types of site
+/// 
+/// Quantity Use Definition
+/// The quantities relating to the IfcSite are defined by the
+/// IfcElementQuantity and attached by the
+/// IfcRelDefinesByProperties relationship. It is accessible by
+/// the inverse IsDefinedBy relationship. The following base
+/// quantities are defined and should be exchanged with the
+/// IfcElementQuantity.Name = 'BaseQuantities'. Other
+/// quantities, being subjected to local standard of measurement, can
+/// be defined with another string value assigned to Name. In
+/// this case a valid value for MethodOfMeasurement has to be
+/// provided.
+/// 
+/// Qto_SiteBaseQuantities: base quantities for all site
+/// occurrences.
+/// 
+/// Spatial Structure Use Definition
+/// The IfcSite is used to build the spatial structure of a
+/// building (that serves as the primary project breakdown and is
+/// required to be hierarchical). The spatial structure elements are
+/// linked together by using the objectified relationship
+/// IfcRelAggregates. The IfcSite references them by its
+/// inverse relationships:
+/// 
+/// IfcSite.Decomposes -- referencing (IfcProject ||
+/// IfcSite) by IfcRelAggregates.RelatingObject, If it
+/// refers to another instance of IfcSite, the referenced
+/// IfcSite needs to have a different and higher
+/// CompositionType, i.e. COMPLEX (if the other IfcSite
+/// has ELEMENT), or ELEMENT (if the other IfcSite has
+/// PARTIAL).
+/// IfcSite.IsDecomposedBy -- referencing (IfcSite ||
+/// IfcBuilding || IfcSpace) by
+/// IfcRelAggregates.RelatedObjects. If it refers to another
+/// instance of IfcSite, the referenced IfcSite needs to
+/// have a different and lower CompositionType, i.e. ELEMENT (if the
+/// other IfcSite has COMPLEX), or PARTIAL (if the other
+/// IfcSite has ELEMENT).
+/// 
+/// If there are building elements and/or other elements directly
+/// related to the IfcSite (like a fence, or a shear wall), they
+/// are associated with the IfcSite by using the objectified
+/// relationship IfcRelContainedInSpatialStructure. The
+/// IfcIfcSite references them by its inverse relationship:
+/// 
+/// IfcSite.ContainsElements -- referencing any subtype of
+/// IfcProduct (with the exception of other spatial structure
+/// element) by
+/// IfcRelContainedInSpatialStructure.RelatedElements.
+/// 
+/// Figure 51 shows the IfcSite as part of the spatial structure. In addition to the logical spatial structure, also the placement hierarchy is shown. In this example the spatial structure hierarchy and the placement hierarchy are identical.
+/// NOTE Detailed requirements on mandatory element containment and placement structure relationships are given in view definitions and implementer agreements.
+/// 
+/// Figure 51 — Site composition
+/// 
+/// Attribute Use Definition
+/// Figure 52 describes the heights and elevations of the IfcSite. It is used to provide the geographic longitude, latitude, and height above sea level for the origin of the site. The origin of the site is the local placement.
+/// The provision of longitude, latitude, height at the IfcSite for georeferencing is provided for upward compatibility reasons. It requires a single instance of IfcSite and WGS84 as coordinate reference system.
+/// For exact georeferencing the new entities IfcCoordinateReferenceSystem and IfcMapConversion should be used.

+/// IfcLocalPlacement shall point to the
+/// IfcSpatialStructureElement of type "IfcSite", if
+/// relative placement is used (e.g. to position a site relative a a

+/// If the relative placement is not used, the absolute placement
+/// is defined within the world coordinate system. If there is only one

+/// 
+/// Spatial Structure Use Definition
+/// The IfcSpace is used to build the spatial structure of a
+/// building (that serves as the primary project breakdown and is
+/// required to be hierarchical). The spatial structure elements are
+/// linked together by using the objectified relationship
+/// IfcRelAggregates. The IfcSpace references them by its

+/// 
+/// IfcSpace.Decomposes -- referencing (IfcSite ||
+/// IfcBuildingStorey || IfcSpace) by
+/// IfcRelAggregates.RelatingObject, If it refers to another
+/// instance of IfcSpace, the referenced IfcSpace
+/// needs to have a different and higher CompositionType, i.e.
+/// COMPLEX (if the other IfcSpace has ELEMENT), or ELEMENT (if
+/// the other IfcSpace has PARTIAL).
+/// IfcSpace.IsDecomposedBy -- referencing (IfcSpace)
+/// by IfcRelAggregates.RelatedObjects. If it refers to another
+/// instance of IfcSpace, the referenced IfcSpace needs
+/// to have a different and lower CompositionType, i.e. ELEMENT
+/// (if the other IfcSpace has COMPLEX), or PARTIAL (if the
+/// other IfcSpace has ELEMENT).
+/// 
+/// If there are building elements and/or other elements directly
+/// related to the IfcSpace (like most furniture and
+/// distribution elements), they are associated with the
+/// IfcSpace by using the objectified relationship
+/// IfcRelContainedInSpatialStructure. The IfcSpace
+/// references them by its inverse relationship:
+/// 
+/// IfcSpace.ContainsElements -- referencing any subtype of
+/// IfcProduct (with the exception of other spatial structure
+/// element) by
+/// IfcRelContainedInSpatialStructure.RelatedElements.
+///

+/// NOTE In cases of inconsistency between the
+/// geometric representation of the IfcSpace and the combined
+/// geometric representations of the surrounding
+/// IfcRelSpaceBoundary, the geometric representation of the
+/// space should take priority over the geometric representation of the
+/// surrounding space boundaries.
+/// Local Placement
+/// The local placement for IfcSpace is defined in its
+/// supertype IfcProduct. It is defined by the
+/// IfcLocalPlacement, which defines the local coordinate system
+/// that is referenced by all geometric representations.
+/// 
+/// The PlacementRelTo relationship of

+/// a space relative to a space group, or a partial space to a
+/// space).
+/// If the relative placement is not used, the absolute placement
+/// is defined within the world coordinate system.
+/// 
+/// Geometric Representations
+/// Currently, the use of a 2D 'FootPrint' representation of type

+/// 
+/// Material Use Definition
+/// 
+/// The material of direct instances IfcStructuralCurveMember (in contrast to instances of the subtype IfcStructuralCurveMemberVarying) is defined by IfcMaterialProfileSetUsage and attached by the IfcRelAssociatesMaterial.RelatingMaterial.  It is accessible by the inverse HasAssociations relationship.  Composite profile beams can be represented by refering to several IfcMaterialProfiles within the IfcMaterialProfileSet that is referenced from the IfcMaterialProfileSetUsage.  In case of tapered members, the material profile usage subtype IfcMaterialProfileSetUsageDual is used which specifies IfcMaterialProfileSets separately at the start and the end of the tapered member.
+/// 
+/// The material (IfcMaterial) in each IfcMaterialProfile(Set) is specified minimally by a name which corresponds with an agreed upon standardized structural material designation.  An external reference to the source which specifies the material designation should be provided.  Alternatively, structural material properties may be provided by means of IfcMechanicalMaterialProperties and IfcExtendedMaterialProperties.
+/// 
+/// The profile (IfcProfileDef) in each IfcMaterialProfile(Set) is specified minimally by a name which corresponds with an agreed upon standardized structural profile designation.  An external reference to the source which specifies the profile designation should be provided.  Alternatively or additionally, explicit profile geometry should be provided by using respective subtypes of IfcProfileDef.  Alternatively or additionally, structural profile properties may be provided by means of subtypes of IfcProfileProperties.
+/// 
+/// An IfcProfileDef is a two-dimensional geometric object with a xp,yp coordinate system.  The profile is inserted into the curve member model thus that the origin of xp,yp is located at the member's reference curve and that xp,yp are parallel with and directed like the local y,z.
+/// 
+/// NOTE   Due to convention in structural mechanics, axis names of IfcStructuralCurveMember differ from axis names of building elements like IfcBeamStandardCase:  The extrusion axis of IfcStructuralCurveMember is called x while the extrusion axis of IfcBeamStandardCase is called z.  Hence x,y,z of IfcStructuralCurveMember correspond with z,x,y of IfcBeamStandardCase.
+/// 
+/// If the profile is meant to be inserted centrically in terms of structural section properties, it is necessary that the origin of xp,yp is identical with the geometric centroid of the profile (commonly also called centre of gravity).  If subtypes of IfcParameterizedProfileDef are used which are only singly symmetric or are asymmetric, an explicit translation by IfcParameterizedProfileDef.Position.Location is required then.
+/// 
+/// If the profile is inserted at its geometric centroid, IfcMaterialProfileSetUsage.CardinalPoint shall be set to 10.
+/// 
+/// Otherwise, the profile is inserted eccentrically and a different cardinal point should be set accordingly.
+/// 
+/// NOTE   Another eccentricity model is available independently of eccentric profile specification:  The reference curve of the member may be located eccentrically relative to the reference points of the connected IfcStructuralPointConnections.  The connection relationship is then established by IfcRelConnectsWithEccentricity.  Whether one or the other or both eccentricity models may be used is subject to information requirements and local agreements.

+/// An IfcSubContractResource can be used in cost estimating and work planning with or without specifying the subcontractor and contract agreement. 
+/// The purpose of an IfcSubContractResource is to indicate work of a particular type that is that is to be engaged through the use of a sub-contract. It's aim is to identify the description of the sub-contract work required. It can be used to identify the generic type of sub-contract resource that is required for a purpose without having to be specific about the actor (person or organization) providing the resource occurrence. It may be particularly useful when creating an overall plan for a process or processes. For instance, within maintenance or work planning there may be a known task that needs to be done which is planned to require an 'insulation specialist'. 
+/// A subcontract resource may be described at various stages and levels of detail through its assignments:

+/// Definition from IAI: A surface feature is a modification at (onto, or into) of the surface of an element.  Parts of the surface of the entire surface may be affected.  The volume and mass of the element may be increased, remain unchanged, or be decreased by the surface feature, depending on manufacturing technology.
+/// 
+/// The standard use of instances of IfcSurfaceFeature is as a part of element type objects (instances of subtypes of IfcElementType).  The part–whole relationship is established by an aggregation relationship object, expressing the decomposition of an element type into one or more additive elements (element parts) and zero or more feature elements.
+/// 
+/// HISTORY New type in IFC 2x4.
+/// 
+/// Containment Use Definition:
+/// 
+/// Surface features shall have no spatial containment relationship to the spatial structure since they are dependent on element types without spatial containment relationships or on an element occurrence with own spatial containment relationship.
+/// 
+/// The SELF\IfcElement.ContainedInStructure relationship shall be NIL.
+/// 
+/// Geometry use definition:
+/// 
+/// The geometric representation of IfcSurfaceFeatureElement is given by the IfcProductDefinitionShape, allowing multiple geometric representation.
+/// 
+/// Local Placement
+/// 
+/// The local placement for IfcSurfaceFeatureElement is defined in its supertype IfcProduct. It is defined by the IfcLocalPlacement, which defines the local coordinate system that is referenced by all geometric representations.
+/// 
+/// In case of features which are part of an element type, absolute placement into the type object's implied coordinate system shall be used.
+///   In case of features which are voiding an element occurrence, the PlacementRelTo relationship of IfcLocalPlacement shall point to the local placement of the respective element.
+/// 
+/// Shape representation
+/// 
+/// Different shape representations may be used, depending on the nature of the feature and information requirements:
+/// 
+/// Symbolic representation, such as the two-dimensional bounding box of a tag.
+///   A geometric set representing the geometric items of a mark.
+///   Surface representations of treated parts of the lement surface by means of IfcShellBasedSurfaceModel.  The faces within the surface model may be included into a B-Rep model within a representation map of the parent element type.
+///

+/// Definition from ISO/CD 10303-42:1992:
+/// A trimmed curve is a bounded curve which is created by taking a selected
+/// portion, between two identified points, of the associated basis curve.
+/// The basis curve itself is unaltered and more than one trimmed curve may
+/// reference the same basis curve. Trimming points for the curve may be
+/// identified by:
+///   parametric value  geometric
+/// position  both of the above 
+/// At least one of these shall be specified at each
+/// end of the
+/// curve. The SenseAgreement makes it possible to
+/// unambiguously define any segment of a closed curve such as a circle.
+/// The combinations of sense and ordered end points make it possible to
+/// define four distinct directed segments connecting two different points
+/// on a circle or other closed curve. For this purpose cyclic properties
+/// of the parameter range are assumed; for example, 370 degrees is
+/// equivalent to 10 degrees. 
+/// The IfcTrimmedCurve has a parameterization
+/// which is inherited from the particular basis curve reference. More
+/// precisely the parameter s of the trimmed curve is derived from the
+/// parameter of the basis curve as follows: 
+///   if SenseAgreement is TRUE: s
+/// = t - t1  if SenseAgreement
+/// is FALSE: s
+/// = t2 - t 
+/// In the above equations t1 is
+/// the value
+/// given by Trim1 or the parameter value corresponding
+/// to point 1 and t2 is the value given by Trim2
+/// or the parameter value corresponding to point 2. The resultant IfcTrimmedCurve
+/// has a parameter ranging from 0 at the first trimming point to |t2
+/// - t1| at the second trimming point. 
+///   NOTE In case
+/// of a closed curve,
+/// it may be necessary to increment t1 or t2 by the parametric length for
+/// consistency with the sense flag.
+/// 
+/// NOTE Corresponding ISO 10303 entity: trimmed_curve; As a further IFC restriction, an IfcTrimmedCurve should only trim a IfcLine or IfcConic. Please refer to ISO/IS 10303-42:1994, p. 54 for the final definition of the formal standard.
+/// 
+/// HISTORY New class in IFC Release 1.0
+/// 
+/// Informal Propositions:
+///   Where both the parameter value and the Cartesian
+/// point
+/// exist for Trim1 and Trim2 they
+/// shall be consistent. (i.e., the BasisCurve
+/// evaluated at the parameter value shall coincide with the specified
+/// point). When a Cartesian point is specified by Trim1
+/// or by Trim2 it shall lie on the BasisCurve.
+/// Except the case of a closed BasisCurve
+/// where both parameter 1 and parameter 2 exist, they shall be consistent
+/// with the sense flag, i.e., (sense = parameter 1 < parameter 2). Or, for every open curve where both
+/// parameter 1 and parameter 2 exist, they shall be consistent with the SenseAgreement,
+/// i.e., SenseAgreement = (parameter 1 <
+/// parameter 2). If both parameter 1
+/// and parameter 2 exist, then parameter 1
+/// <> parameter 2. For a
+/// closed base curve, e.g. IfcCircle or IfcEllipse,
+/// this also applies to the cyclic properties, as 360' is equal to 0',
+/// parameter 1 = 360' and parameter 2 = 0' are treated as being equal and
+/// therefore violating this proposition. When
+/// a parameter value is specified by Trim1
+/// or Trim2 it shall lie within the parametric range
+/// of the BasisCurve.
+/// Additional illustration from IAI:
+///   The
+/// figure above shows the four arcs (dashed blue and
+/// green lines with arrow showing different orientations) that can be
+/// defined by the same BasisCurve (of type IfcCircle)
+/// and the same trimming points (given by Cartesian points and parameter
+/// values) by using different assignments to Trim1 and
+/// Trim2 and SenseAgreement.  
+/// Note: Since the BasisCurve is closed (type IfcCircle),
+/// the exception of the informal proposition IP3 applies, i.e. the sense
+/// flag is not
+/// required to be consistent with the parameter values of Trim1
+/// and Trim1, so the rule (sense = parameter 1
+/// < parameter 2) may not be fulfilled.

+/// An IfcWorkCalendar defines working and non-working time periods for tasks and resources. It enables to define both specific time periods, such as from 7:00 till 12:00 on 25th August 2009, as well as repetitive time periods based on frequently used recurrence patterns, such as each Monday from 7:00 till 12:00 between 1st March 2009 and 31st December 2009.
+/// 
+/// HISTORY  New entity in IFC2x4.
+/// 
+/// A work calendar is a subtype of IfcControl and thus inherits the feature for controlling other objects through IfcRelAssignsToControl, which is used to define a work calendar for tasks (IfcTask) and resources (IfcResource). It also inherits a name and description attribute, whereas a name shall be given and a description may be given as an indication of its content and usage.
+/// 
+/// The definition of time periods can be derived from a base calendar and/or modified/defined by a set of working times and non-working exception times. All time periods defined by IfcWorkCalendar.ExceptionTimes override the time periods inherited from the base calendar (base calendar is defined as the next applicable calendar for the task or resource). Thus, exception times replace the working times from the base calendar.
+/// 
+/// The base calendar of a work calendar is defined by IfcRelAssignsToControl, where IfcRelAssignsToControl.RelatingControl is linked with the base calendar and IfcRelAssignsToControl.RelatedObjects is linked with work calendars that are derived from the base calendar. Although not restricted by the IfcRelAssignsToControl relationship it is only allowed to have one base calendar.
+/// 
+/// Figure 17 shows the definition of a work calendar, which is defined by a set of work times and exception times. The work times are defined as recurring patterns with optional boundaries (applying from and/or to a specific date). The shown example defines a simple work calendar with working times Monday to Thursday 8:00 to 12:00 and 13:00 to 17:00, Friday 8:00 to 14:00 and as exception every 1st Monday in a month the work starts one hour later - i.e. the working time on every 1st Monday in a month is overriden to be 9:00 to 12:00 and 13:00 to 17:00. Both the working time and the exception time is valid for the period of 01.09.2010 till 30.08.2011.

+/// 
+/// CHANGE IFC2x4  Corrected assignment of resources to work control in documentation. Assignment of tasks to work control updated based on changes of task time definitions and the introduction of a summary task. Identifier has been renamed (now Identification) and promoted to supertype IfcControl
+/// 
+/// A work control may have resources assigned to it, this is
+///   handled by the IfcRelAssignsToControl relationship.
+///   A work control should also define a context that gives

+/// 
+/// From IFC2x4 onwards the assignment of tasks to the work
+///   control is handled by the IfcRelAssignsToControl
+///   relationship. IfcRelAssignsTasks as used in previous
+///   IFC releases has been deleted and can not be used any
+///   longer. Another change in IFC2x4 is that it is not
+///   necessary to assign each task to a work control as it is
+///   regarded to be sufficient if the summary task (root task in
+///   the task hierarchy defined through IfcRelNests
+///   relationships) is assigned to a work control.

+/// Definition from IAI: A zone isa group of spaces,

+/// hierarchical (in contrary to the spatial structure of a project -
+/// see IfcSpatialStructureElement), i.e. one individual
+/// IfcSpace may be associated with zero, one, or several
+/// IfcZone's. IfcSpace's are grouped into an
+/// IfcZone by using the objectified relationship
+/// IfcRelAssignsToGroup as specified at the supertype
+/// IfcGroup.
+/// NOTE Certain use cases may restrict the
+/// freedom of non hierarchical relationships. In some building
+/// service use cases the zone denotes aview based delimited volume
+/// for the purpose of analysis and calculation. This type of zone
+/// cannot overlap with respect to that analysis, but may overlap
+/// otherwise.
+/// An IfcZone is a spatial system under which individual
+/// IfcSpace's (and other IfcZone's) are grouped. In
+/// contrary to the IfcSpatialZone entity, IfcZone is a
+/// mere grouping, it can not define an own geometric representation
+/// and placement. Therefore it cannot be used for spatial zones
+/// having a different shape and size compared to the shape and size
+/// of aggregated spaces.
+/// NOTE The IfcZone is regarded as the
+/// spatial system (as compared to the building service, electrical,
+/// or analytical system), the name remains IfcZone for
+/// compatibility reasons, instead of using a proper naming
+/// convention, like IfcSpatialSystem.
+/// NOTE One of the purposes of a zone is to
+/// define a fire compartmentation. In this case it defines the
+/// geometric information about the fire compartment (through the
+/// contained spaces) and information, whether this compartment is
+/// ventilated or sprinkler protected. In addition the fire risk code
+/// and the hazard type can be added, the coding is normally defined
+/// within a national fire regulation. All that information is
+/// available within the relevant property sets. Again, if an
+/// independent shape has to be provided to the fire compartment,
+/// then the entity IfcSpatialZone shall be
+/// used.
+/// RECOMMENDATION In case of a zone denoting a
+/// (fire) compartment, the following types should be used, if
+/// applicable, as values of the ObjectType attribute:
+/// 
+/// FireCompartment - a zone of spaces, collected to
+/// represent a single fire compartment.
+/// ElevatorShaft - a collection of spaces within an
+/// elevator, potentially going through many storeys.
+/// RisingDuct
+/// RunningDuct
+/// 
+/// Additional classifications of the IfcZone, as provided
+/// by a national classification system, can be assigned by using the
+/// IfcRelAssociatesClassification relationship, accessible
+/// via the inverse attribute HasAssociations. The
+/// IfcZone can be assigned to a spatial structure element, it
+/// refers to, e.g. to a particular IfcBuildingStorey by using
+/// the IfcRelServicesBuildings relationship, accessible via
+/// the inverse attribute ServicesBuilding.

+/// An asset is a uniquely identifiable grouping of elements acting as a single entity that has a financial value or that can be operated on as a single unit.

+/// An asset is generally the level of granularity at which maintenance operations are undertaken. An asset is a group that can contain one or more elements. Whilst the financial value of a component or element can be defined, financial value is also defined for accounting purposes at the level of the asset.  There are a number of actors that can be associated with an asset, each actor having a role. Actors within the scope of the project are indicated using the IfcRelAssignsToActor relationship in which case roles should be defined through the IfcActorRole class; otherwise principal actors are identified as attributes of the class. In the existence of both, direct attributes take precedence.  There are a number of costs that can be associated with an asset, each cost having a role. These are specified through the OriginalValue, CurrentValue, TotalReplacementCost and DepreciatedValue attributes.

+/// Definition from ISO/CD 10303-42:1992: A B-spline curve is a piecewise parametric polynomial or rational curve described in terms of control points and basis functions. The B-spline curve has been selected as the most stable format to represent all types of polynomial or rational parametric curves. With appropriate attribute values it is capable of representing single span or spline curves of explicit polynomial, rational, Bezier or B-spline type. 
+/// 
+/// Interpretation of the data is as follows: 
+/// 
+/// All weights shall be positive and the curve is given by 
+/// 
+/// k+1 
+///   = number of control points 
+/// 
+/// Pi 
+///   = control points 
+/// 
+/// wi 
+///   = weights 
+/// 
+/// d 
+///   = degree 
+/// 
+/// The knot array is an array of (k+d+2) real numbers
+///   [u-d ... uk+1], such that for
+///   all indices j in [-d,k], uj <=
+///   uj+1. This array is obtained from the knot data list by
+///   repeating each multiple knot according to the multiplicity. N
+///   di, the ith normalized B-spline basis function
+///   of degree d, is defined on the subset [ui-d, ... ,
+///   ui+1] of this array. 
+/// 
+/// Let L denote the number of distinct values among the
+///   d+k+2 knots in the knot array; L will be referred to as
+///   the 'upper index on knots'. Let mj denote the multiplicity
+///   (number of repetitions) of the jth distinct knot. Then
+/// 
+/// All knot multiplicities except the first and the last shall be in
+///   the range 1 ... degree; the first and last may have a maximum value of degree +
+///   1. In evaluating the basis functions, a knot u of e.g. multiplicity 3 is
+///   interpreted as a string u, u, u, in the knot array. The B-spline curve
+///   has 3 special subtypes (Note: only 1, Bezier curve, included in this IFC
+///   release) where the knots and knot multiplicities are derived to provide
+///   simple default capabilities. 
+///   Logical flag is provided to indicate whether the curve self

+/// possible non geometric IfcProfileProperties have to be
+/// used.
+/// Geometry Use Definition:

+/// Definition from ISO 6707-1:1989: Structural member of

+/// <An IfcColumn is a vertical
+/// structural member which often is aligned with a structural grid
+/// intersection. It represents a vertical, or nearly vertical,
+/// structural member that transmits, through compression, the weight
+/// of the structure above to other structural elements below. It

+/// The IFC specification provides two entities for column
+/// occurrences:
+/// 
+/// IfcColumnStandardCase used for all occurrences of
+/// columns, tthat have a profile defined that is swept along a
+/// directrix. The profile might be changed uniformly by a taper
+/// definition along the directrix. The profile parameter and its
+/// cardinal point of insertion can be fully described by the
+/// IfcMaterialProfileSetUsage. These beams are always
+/// represented geometricly by an 'Axis' and a 'SweptSolid' or
+/// 'AdvancedSweptSolid' shape representation (or by a 'Clipping'
+/// geometry based on the swept solid), if a 3D geometric
+/// representation is assigned. In addition they have to have a
+/// corresponding IfcMaterialProfileSetUsage assigned.
+/// NOTE View definitions and implementer
+/// agreements may further constrain the applicable geometry types,
+/// e.g. by excluding tapering from an IfcColumnStandardCase
+/// implementation.
+/// 
+/// IfcColumn used for all other occurrences of columns,
+/// particularly for columns with changing profile sizes along the
+/// extrusion, or columns defined by non-linear extrusion, or columns
+/// having only 'Brep', or 'SurfaceModel' geometry.
+/// 
+/// HISTORY New entity in IFC Release 1.0
+/// 
+/// Type Use Definition
+/// IfcColumn defines the occuurence of any column, common

+/// IfcColumnType is attached using the
+/// IfcRelDefinedByType.RelatingType objectified relationship
+/// and is accessible by the inverse IsTypedBy attribute.
+/// If no IfcColumnType is attached(i.e. if only
+/// occurrence information is given) the PredefinedType should

+/// Material Use Definition
+/// The material of the IfcColumn is defined by the
+/// IfcMaterialProfileSet or as fallback by IfcMaterial
+/// and attached by the
+/// IfcRelAssociatesMaterial.RelatingMaterial. It is
+/// accessible by the inverse HasAssociations
+/// relationship.
+/// Note: It is illegal to assign an

+/// IfcRelAssociatesMaterial.RelatingMaterial to
+/// IfcMaterialProfileSet or IfcMaterial. If both are
+/// given, then the material directly assigned to IfcColumn
+/// overrides the material assigned to IfcColumnType.

+/// Containment Use Definition

+/// IfcRelContainedInSpatialStructure, refering to it by its

+/// Subtypes ofIfcSpatialStructureElement are valid spatial

+/// container.
+/// The IfcColumn, may be aggregated into an element
+/// assembly using the objectified relationship
+/// IfcRelAggregates, refering to it by its inverse attribute
+/// SELF\IfcObjectDefinition.Decomposes. Any subtype of
+/// IfcElement can be an element assembly, with
+/// IfcElementAssembly as a special focus subtype. In this
+/// case it should not be additionally contained in the project
+/// spatial hierarchy,
+/// i.e.SELF\IfcElement.ContainedInStructure should be
+/// NIL.
+/// 
+/// Geometry Use Definition
+/// The geometric representation of IfcColumn is given by
+/// the IfcProductDefinitionShape, allowing multiple geometric
+/// representations. Included are:
+/// Local Placement
+/// The local placement for IfcColumn is defined in its
+/// supertype IfcProduct. It is defined by the
+/// IfcLocalPlacement, which defines the local coordinate
+/// system that is referenced by all geometric representations.
+/// 
+/// The PlacementRelTo relationship of

However, they are used as resources in the process &#145;pouring concrete&#146; in a later stage of the project. IfcConstructionProductResource occurrences  are explicitly instances of IfcProduct and may be drawn from various of the subtypes, for instance IfcElementComponent, IfcElementAssembly, IfcProxy (for particular cases where more precise usage details are not available).  The product that is used as a construction resource is referenced using the IfcRelAssignsToResource.RelatedObjects relationship.

+/// 
+/// Type use definition
+/// IfcConstructionProductResource defines the occurrence of any product resource; common information about product resource types is handled by IfcConstructionProductResourceType.  The IfcConstructionProductResourceType (if present) may establish the common type name, common properties, and common productivities for various task types using IfcRelAssignsToProcess.  The IfcConstructionProductResourceType is attached using the IfcRelDefinesByType.RelatingType objectified relationship and is accessible by the inverse IsTypedBy attribute.
+/// 
+/// Assignment use definition
+/// In addition to assignments specified at the base class IfcConstructionResource, a construction product resource may have assignments of its own using IfcRelAssignsToResource where RelatingResource refers to the IfcConstructionProductResource and RelatedObjects contains one or more IfcProduct subtypes as shown in Figure 185.  Such relationship indicates the products used as input for the resource.  Such products are not contained within a building structure but are referenced within a construction spatial zone, specifically IfcSpatialZone with PredefinedType=CONSTRUCTION, which is aggregated within the IfcProject.  There may be multiple chains of production such that the assigned products may have their own task and resource assignments.

+/// Definition from ISO 6707-1:1989: term used: Finishing -

+/// A covering is an element which
+/// covers some part of another element and is fully dependent on
+/// that other element. The IfcCovering defines the occurrence
+/// of a covering type, that (if given) is expressed by the
+/// IfcCoveringType. Examples of coverings include wall
+/// claddings, floorings and suspended ceilings. Coverings are
+/// elements with relationships to the covered element and the space
+/// on the other side, they may contain openings, assigned by
+/// IfcRelVoidsElement, material information, assigned by
+/// IfcRelAssociatesMaterial, and others.
+/// NOTE A more basic information about claddings,
+/// floorings, and ceilings of a space can be attached to
+/// IfcSpace's using the Pset_SpaceCommon properties. Then
+/// only a name can be provided and the covering quantities would be
+/// interpreted from the space quantities.
+/// Coverings can be assigned to
+/// 
+/// a space represented by IfcSpace
+/// 
+/// using the inverse relationship CoversSpaces pointing
+/// to IfcRelCoversSpaces. The space is then accessible via
+/// IfcRelCoversSpaces.RelatedSpace. It defines to which space
+/// a covering is facing towards.
+/// 
+/// NOTE The mere containment relationship between an
+/// IfcCovering and an IfcSpace is
+/// created by using
+/// IfcRelContainedInSpatialStructure
+/// 
+/// a space boundary represented by IfcRelSpaceBoundary
+/// 
+/// using the inverse relationship ProvidesBoundaries

+/// 
+/// The following guideline shall apply:
+/// 
+/// (default) if the space has coverings that may not have an own
+/// shape representation and no defined relationships to the building
+/// elements they cover, then the IfcCovering shall be
+/// assigned to IfcSpace using the IfcRelCoversSpaces
+/// relationship,
+/// if the space has coverings that have an own shape
+/// representation and the space has defined space boundaries, then
+/// the covering, which relates to that space, may be assigned to the

+/// 
+/// The IfcDistributionElement is further specialized in

+/// HISTORY New entity in
+/// IFC Release 1.5.
+/// IFC2x4 CHANGE The entity is marked
+/// as deprecated for instantiation - will be made ABSTRACT after
+/// IFC2x4.
+/// Relationship Use Definition
+/// 
+/// Ports - information, whether the distribution element has
+/// ports for system connections
+/// 
+/// objectified relationship:
+/// IfcRelConnectsPortToElement
+/// object referenced by relationship: IfcPort
+/// inverse attribute: HasPorts
+/// 
+/// Type Use Definition
+/// The IfcDistributionElement defines the occurrence of
+/// any HVAC, electrical, sanitary or other element within a
+/// distribution system. Common information about distribution
+/// element types (or styles) is handled by subtypes of
+/// IfcDistributionElementType. The
+/// IfcDistributionElementType (if present) may establish the
+/// common type name, usage (or predefined) type, common material,
+/// common set of properties and common shape representations (using
+/// IfcRepresentationMap). The
+/// IfcDistributionElementType is attached using the
+/// IfcRelDefinedByType.RelatingType objectified relationship
+/// and is accessible by the inverse IsDefinedBy
+/// attribute.
+/// The assignment of types to distribution element occurrences is
+/// vital for providing the additional meaning, or ontology, of the
+/// distribution element. Many specialized type are defined in other
+/// schemas of the IFC specification.
+/// Quantity Use Definition
+/// The quantities relating to the IfcDistributionElement
+/// are defined by the IfcElementQuantity and attached by the
+/// IfcRelDefinesByProperties. A detailed specification for
+/// individual quantities is introduced at the level of subtypes of
+/// IfcDistributionElement.
+/// Containment Use Definition
+/// The IfcDistributionElement may participate in two
+/// different containment relationships. The first (and in most
+/// implementation scenarios mandatory) relationship is the
+/// hierachical spatial containment, the second (optional)
+/// relationship is the aggregation within anelement assembly.
+/// 
+/// The IfcDistributionElement is places within the
+/// project spatial hierarchy using the objectified relationship
+/// IfcRelContainedInSpatialStructure, referring to it by its
+/// inverse attribute SELF\IfcElement.ContainedInStructure.
+/// Subtypes ofIfcSpatialStructureElement are valid spatial
+/// containers, with IfcSpace being the default
+/// container.
+/// The IfcDistributionElement may be aggregated into an
+/// element assembly using the objectified relationship
+/// IfcRelAggregates, referring to it by its inverse attribute
+/// SELF\IfcObjectDefinition.Decomposes. Any subtype of
+/// IfcElement can be an element assembly, with
+/// IfcElementAssembly as a special focus subtype. In this
+/// case it should not be additionally contained in the project
+/// spatial hierarchy,
+/// i.e.SELF\IfcElement.ContainedInStructure should be
+/// NIL.
+/// 
+/// Geometry Use Definitions
+/// The geometric representation of IfcDistributionElement
+/// is given by the IfcProductDefinitionShape, allowing
+/// multiple geometric representation.
+/// Local Placement
+/// The local placement for IfcDistributionElement is
+/// defined in its supertype IfcProduct. It is defined by the
+/// IfcLocalPlacement, which defines the local coordinate
+/// system that is referenced by all geometric representations.
+/// 
+/// The PlacementRelTo relationship of
+/// IfcLocalPlacement shall point (if given) to the local
+/// placement of the same IfcSpatialStructureElement , which
+/// is used in the ContainedInStructure inverse attribute, or
+/// to a spatial structure element at a higher level, referenced by
+/// that.
+/// If the relative placement is not used, the absolute placement
+/// is defined within the world coordinate system.
+/// 
+/// Geometric Representations
+/// The geometric representation of IfcDistributionElement
+/// is defined using different geometric representation types for the
+/// various subtypes. Only general recommendations are given at the
+/// level of the supertype, further constraints are defined at the
+/// level of its subtypes.
+/// 
+/// all occurrences of IfcDistributionElement (and its
+/// subtypes) should (whenever possible) share a representation map
+/// established by the assigned type. The geometric representation of
+/// the occurrence is then an IfcMappedItem. The
+/// IfcShapeRepresentation has:
+/// 
+/// RepresentationIdentifier : 'Body'
+/// RepresentationType : 'MappedRepresentation'
+/// 
+/// The shared geometric representation of the distribution
+/// element type (or in some cases of the distribution element)
+/// should follow (if applicable) the the following guidelines:
+/// 
+/// all fixtures (all non distribution flow elements, i.e.
+/// everything which is not a duct, a pipe, a cable, or a cable
+/// carrier) should be defined by an b-rep geometry. This includes
+/// also the complex flow fitting elements (e.g. Y branch or T
+/// branch) or distribution flow elements with size changes (e.g.
+/// reducer). The IfcShapeRepresentation has:
+/// 
+/// RepresentationIdentifier : 'Body'
+/// RepresentationType : 'Brep'
+/// 
+/// if the geometric model consistency of a b-rep shape
+/// representation can not be guaranteed (arcwise connected volume
+/// bounded by faces, each being connected, oriented, finite, closed
+/// 2-manifold), a surface representation based on open shells should
+/// be used. The IfcShapeRepresentation then has:
+/// 
+/// RepresentationIdentifier : 'Body'
+/// RepresentationType : 'SurfaceModel'
+/// 
+/// all "simple" distribution flow elements (general ducts and
+/// pipes) are defined by sweep geometry. The
+/// IfcShapeRepresentation has:
+/// 
+/// RepresentationIdentifier : 'Body'
+/// RepresentationType : 'SweptSolid'
+/// 
+/// an additional representation type for all "simple"
+/// distribution flow elements (general ducts and pipes) is the
+/// ability to have a simple line based representation. The
+/// IfcShapeRepresentation has:
+/// 
+/// RepresentationIdentifier : 'FootPrint'
+/// RepresentationType : 'GeometricCurveSet'
+/// 
+/// if only the analytical shape is required for which the exact
+/// interpolation between the cross sections is not required, a
+/// sectioned spine can be used.
+/// 
+/// RepresentationIdentifier : 'Body'
+/// RepresentationType : 'SectionedSpine'

If the IfcDistributionFlowElementType has ports or aggregated elements, such objects are reflected at the IfcDistributionFlowElement occurrence using the IfcRelDefinesByObject relationship.  Direct instantiation of IfcDistributionFlowElement with IfcObject.ObjectType asserted provides the meaning of a distribution flow element proxy.
+/// 
+/// Property Set Use Definition
+/// The property sets relating to this entity are defined by IfcPropertySet and attached by the IfcRelDefinesByProperties relationship. They are accessible by the IsDefinedBy inverse attribute.  Property sets may also be specified at the IfcDistributionFlowElementType, defining the common property data for all occurrences of the same type.

+/// IfcElement (IfcRelInterferesElements) : Indicates interference with another element and precedence, such as a pipe going through a wall.
+/// IfcOpening (IfcRelFillsElement) : Indicates embedding an element within another element (implying a cutout), such as an air terminal or junction box embedded within a wall.
+/// IfcDistributionPort (IfcRelConnectsPortToElement) : Indicates ports on the element which may be connected to other elements for flow distribution of solids, liquids, gas, or electricity.  Standard port names, types, and directions are defined at subtypes.

+/// 'Lighting': Represents the light emission of the item having IfcShapeRepresentation.RepresentationType of 'LightSource' and containing one or more IfcLightSource subtypes.  This representation is most applicable to lamps and light fixtures, however may be used at other elements that emit light.
+/// 
+/// For all representations, if a IfcDistributionFlowElement occurrence is defined by a IfcDistributionFlowElementType having a representation of the same identifier, then 'MappedRepresentation' should be used at the occurrence unless overridden.

+/// 
+/// HISTORY New entity in IFC 2x4.
+/// 
+/// The group IfcDistributionSystem
+/// defines the occurrence of a specialized system for use within the context of building services.
+/// 
+/// NOTE: For electrical power systems, IfcElectricalCircuit has been used for low-voltage (12-1000 V) power systems and has been deprecated in IFC2x4; IfcDistributionSystem with PredefinedType 'ELECTRICAL' should now be used instead.
+/// 
+/// Important functionalities for the description of a distribution system are derived from existing IFC entities:
+/// 
+/// From IfcSystem it inherits the ability to couple the distribution system via IfcRelServicesBuildings to one or more IfcSpatialElement subtypes as necessary.
+/// 
+/// From IfcGroup it inherits the inverse attribute IsGroupedBy, pointing to the relationship class IfcRelAssignsToGroup. This allows to group distribution elements (instances of IfcDistributionElement subtypes), and in special cases ports directly (instances of IfcDistributionPort).
+/// 
+/// From IfcObject it inherits the inverse attribute IsDecomposedBy pointing to the relationship class IfcRelAggregates. It provides the hierarchy between the separate (partial) distribution systems.  For example, an electrical main circuit may be aggregated into branch circuits.
+/// 
+/// Property Set Use Definition:
+/// 
+/// The property sets relating to this entity are defined by the IfcPropertySet and attached by the IfcRelDefinesByProperties relationship. It is accessible by the inverse IsDefinedBy relationship.  The following property set definitions specific to this entity are part of this IFC release:
+/// 
+/// Pset_DistributionSystemCommon: common property set for distribution system occurrences
+/// 
+/// Pset_DistributionSystemTypeElectrical: property set for electrical systems
+/// 
+/// Pset_DistributionSystemTypeVentilation: property set for ventilation systems
+/// 
+/// Assignment Use Definition:
+/// 
+/// For the most common case of an IfcDistributionElement subtype containing ports of a particular PredefinedType that all belong to the same distribution system, the IfcDistributionElement is assigned to the IfcDistributionSystem via the IfcRelAssignsToGroup relationship, where IfcDistributionPort's are implied as part of the corresponding system based on their PredefinedType.  An IfcDistributionElement may belong to multiple systems, however only one IfcDistributionSystem of a particular PredefinedType.
+/// 
+/// For rare cases where an IfcDistributionElement subtype contains ports of the same PredefinedType yet different ports belong to different systems, alternatively each IfcDistributionPort may be directly assigned to a single IfcDistributionSystem via the IfcRelAssignsToGroup relationship, where the PredefinedType must match.  Such assignment indicates that the IfcDistributionSystem assigned from the IfcDistributionPort overrides any such system of the same PredefinedType assigned from the containing IfcDistributionElement, if any.
+/// 
+/// Additionally, an IfcDistributionSystem may in turn be assigned to an IfcDistributionPort indicating the host or origination of the system using IfcRelAssignsToProduct.
+/// 
+/// EXAMPLE: A gas-powered hot water heater may have three ports: GAS, DOMESTICCOLDWATER, and DOMESTICHOTWATER.  The heater is a member of two systems (GAS and DOMESTICCOLDWATER), and hosts one system (DOMESTICHOTWATER) at the corresponding port.

+/// Definition from ISO 6707-1:1989: Construction for
+/// closing an opening, intended primarily for access with hinged,
+/// pivoted or sliding operation.
+/// The door is a building element
+/// that is predominately used to provide controlled access for
+/// people and goods. It includes constructions with hinged, pivoted,
+/// sliding, and additionally revolving and folding operations. A
+/// door consists of a lining and one or several panels.
+/// The IfcDoor defines a particular occurrence of a door
+/// inserted in the spatial context of a project. A door can:
+/// 
+/// be inserted as a filler in an opening using the
+/// IfcRelFillsElement relationship, then the IfcDoor
+/// has an inverse attribute FillsVoids provided,
+/// 
+/// NOTE View definitions or
+/// implementer agreements may restrict the relationship to only
+/// include one window (or door) into one opening.
+/// 
+/// be part of an element assembly, in general an
+/// IfcCurtainWall, using the IfcRelAggregates
+/// relationship, then the inverse attribute Decomposes is
+/// provided.
+/// or be a "free standing" door, then the IfcDoor has no
+/// inverse attributes FillsVoids or Decomposes
+/// provided.
+/// 
+/// The IFC specification provides two entities for door
+/// occurrences:
+/// 
+/// IfcDoorStandardCase used for all occurrences of doors,
+/// that have a 'Profile' shape representation defined to which a set
+/// of shape parameters for lining and framing properties apply.
+/// Additionally it requires the provision of an IfcDoorType
+/// that references one IfcDoorLiningProperties and on to many
+/// IfcDoorPanelProperties.
+/// 
+/// NOTE see
+/// IfcDoorStandardCase for all specific constraints imposed
+/// by this subtype.
+/// 
+/// IfcDoor used for all other occurrences of doors,
+/// particularly for doors having only 'Brep', or 'SurfaceModel'
+/// geometry without applying shape parameters.
+/// 
+/// The actual parameter of the door and/or its shape are defined
+/// by the IfcDoor as the occurrence definition (or project
+/// instance), or by the IfcDoorType as the specific definition (or
+/// project type). The following parameters are given:
+/// 
+/// at the IfcDoor or IfcDoorStandardCase for
+/// occurrence specific parameters. The IfcDoor
+/// specifies:
+/// 
+/// the door width and height
+/// the door opening direction (by the y-axis of the
+/// ObjectPlacement)
+/// 
+/// at the IfcDoorType, to
+/// which the IfcDoor is related by the inverse relationship
+/// IsDefinedBy pointing to IfcRelDefinesByType, for
+/// type parameters common to all occurrences of the same type.
+/// 
+/// the operation type (single swing, double swing, revolving,
+/// etc.)
+/// the door hinge side (by using two different styles for right
+/// and left opening doors)
+/// the construction material type
+/// the particular attributes for the lining by the
+/// IfcDoorLiningProperties
+/// the particular attributes for the panels by the
+/// IfcDoorPanelProperties
+/// 
+/// HISTORY New entity in IFC Release 1.0.
+/// IFC2x4 CHANGE The attributes PredefinedType and OperationType are added, the applicable type object has been changed to IfcDoorType.
+/// 
+/// Material Use Definition
+/// The material of the IfcDoor is defined by the
+/// IfcMaterialConstituentSet or as fall back by
+/// IfcMaterial and attached by the
+/// IfcRelAssociatesMaterial.RelatingMaterial. It is
+/// accessible by the inverse HasAssociations
+/// relationship.
+/// The following keywords for
+/// IfcMaterialConstituentSet.MaterialConstituents[n].Name
+/// shall be used:
+/// 
+/// 'Lining' - to indicate that the material constituent applies
+/// to to the door lining
+/// 'Framing' - to indicate that the material constituent applies
+/// to to the door panel(s), if not provided, the 'Lining' material
+/// information applied to panel(s) as well
+/// 'Glazing' - to indicate that the material constituent applies
+/// to to the glazing part
+/// 
+/// If the fall back single IfcMaterial is referenced, it
+/// applies to the lining and framing of the door.
+/// Property Set Use Definition:
+/// The property sets relating to the IfcDoor are defined
+/// by the IfcPropertySet and attached by the
+/// IfcRelDefinesByProperties relationship. It is accessible
+/// by the inverse IsDefinedBy relationship. The following
+/// property set definitions specific to the IfcDoor are part
+/// of this IFC release:
+/// 
+/// Pset_DoorCommon: common property set for all
+/// door occurrences
+/// Pset_DoorWindowGlazingType: specific property
+/// set for the glazing properties of the door glazing, if
+/// available
+/// Pset_DoorWindowShadingType: specific property
+/// set for the shading properties of the door glazing, if
+/// available
+/// 
+/// Quantity Use Definition
+/// The quantities relating to the IfcDoor are defined by
+/// the IfcElementQuantity and attached by the
+/// IfcRelDefinesByProperties relationship. It is accessible
+/// by the inverse IsDefinedBy relationship. The following
+/// base quantities are defined and should be exchanged with the
+/// IfcElementQuantity.Name = 'BaseQuantities'. Other
+/// quantities can be defined being subjected to local standard of
+/// measurement with another string value assigned to
+/// MethodOfMeasurement. Quanties shall be never assigned to
+/// the IfcDoorType.
+/// 
+/// Qto_DoorBaseQuantities: base quantities for
+/// all door occurrences.
+/// 
+/// Containment Use Definition
+/// The IfcDoor, as any subtype of
+/// IfcBuildingElement, may participate in two different
+/// containment relationships as shown in Figure 96. The first (and in most implementation
+/// scenarios mandatory) relationship is the hierachical spatial
+/// containment, the second (optional) relationship is the
+/// aggregation within anelement assembly.
+/// 
+/// The IfcDoor is places within the project spatial
+/// hierarchy using the objectified relationship
+/// IfcRelContainedInSpatialStructure, refering to it by its
+/// inverse attribute SELF\IfcElement.ContainedInStructure.
+/// Subtypes ofIfcSpatialStructureElement are valid spatial
+/// containers, with IfcBuildingStorey being the default
+/// container.
+/// The IfcDoor may be aggregated into an element assembly
+/// using the objectified relationship IfcRelAggregates,
+/// refering to it by its inverse attribute
+/// SELF\IfcObjectDefinition.Decomposes. Doors may be part of
+/// an IfcCurtainWall as a special focus subtype. In this case
+/// it should not be additionally contained in the project spatial
+/// hierarchy, i.e.SELF\IfcElement.ContainedInStructure
+/// should be NIL.
+/// 
+/// NOTE The containment shall be defined independently of the
+/// filling relationship, that is, even if the IfcDoor is a
+/// filling of an opening established by IfcRelFillsElement,
+/// it is also contained in the spatial structure by an
+/// IfcRelContainedInSpatialStructure.
+/// 
+/// Figure 96 — Door containment
+/// 
+/// Geometry Use Definitions:
+/// The geometric representation of IfcDoor is given by the
+/// IfcProductDefinitionShape, allowing multiple geometric
+/// representations. The IfcDoor, in case of an occurrance
+/// object, gets its parameter and shape from the IfcDoorType.
+/// If an IfcRepresentationMap (a block definition) is defined
+/// for the IfcDoorType, then the IfcDoor inserts it
+/// through the IfcMappedItem.
+/// Local Placement
+/// The local placement for IfcDoor is defined in its
+/// supertype IfcProduct. It is defined by the
+/// IfcLocalPlacement, which defines the local coordinate
+/// system that is referenced by all geometric representations.
+/// 
+/// The PlacementRelTo relationship of
+/// IfcLocalPlacement shall point to the local placement of
+/// the same element (if given), in which the IfcDoor is used
+/// as a filling (normally an IfcOpeningElement), as provided
+/// by the IfcRelFillsElement relationship.
+/// If the IfcDoor is not inserted into an
+/// IfcOpeningElement, then the PlacementRelTo
+/// relationship of IfcLocalPlacement shall point (if given)
+/// to the local placement of the same
+/// IfcSpatialStructureElement that is used in the
+/// ContainedInStructure inverse attribute or to a referenced
+/// spatial structure element at a higher level.
+/// If the relative placement is not used, the absolute placement
+/// is defined within the world coordinate system.
+/// 
+/// Geometric Representation
+/// Thegeometric representation of IfcDoor is defined
+/// using the following (potentiallymultiple)
+/// IfcShapeRepresentation's for its
+/// IfcProductDefinitionShape:
+/// 
+/// Profile: A'Curve3D'
+/// consisting of a single losed curve defining the outer boundary of
+/// the door (lining). The door parametric representation uses this
+/// profile in order to apply the door lining and panel parameter. If
+/// not provided, the profile of the IfcOpeningElement is
+/// taken.
+/// FootPrint: A 'GeometricCurveSet', or 'Annotation2D'
+/// representation defining the 2D shape of the door
+/// Body: A 'SweptSolid', 'SurfaceModel', or 'Brep'
+/// representation defining the 3D shape of the door.
+/// 
+/// In addition the parametric representation of a (limited) door
+/// shape is available by applying the parameters from
+/// IfcDoorType referencing IfcDoorLiningProperties and
+/// IfcDoorPanelProperties. The purpose of the parameter is
+/// described at those entities and below (door opening operation by
+/// door type).
+/// Profile -'Curve3D' representation
+/// The door profile is represented by a three-dimensional closed
+/// curve within a particular shape representation. The profile is
+/// used to apply the parameter of the parametric door
+/// representation.The following attribute values for the
+/// IfcShapeRepresentation holding this geometric
+/// representation shall be used:
+/// 
+/// RepresentationIdentifier : 'Profile'
+/// RepresentationType : 'Curve3D', only a single closed
+/// curve shall be contained in the set of
+/// IfcShapeRepresentation.Items.
+/// 
+/// A 'Profile' representation has to be provided if:
+/// 
+/// a parametric representation shall be applied to the door
+/// AND
+/// 
+/// thedoor is 'free standing', or
+/// the opening into which thedoor is inserted is not extruded
+/// horizontally (i.e. where the opening profile does not match
+/// thedoor profile)
+/// 
+/// FootPrint -'GeometricCurveSet' or 'Annotation2D'
+/// representation
+/// The door foot print is represented by a set of
+/// two-dimensionalcurves (or in case of 'Annotation2D' additional
+/// hatching and text) within a particular shape representation. The
+/// foot print is used for the planview representation of the
+/// door.The following attribute values for the
+/// IfcShapeRepresentation holding this geometric
+/// representation shall be used:
+/// 
+/// RepresentationIdentifier : 'FootPrint'
+/// RepresentationType : 'GeometricCurveSet', or
+/// 'Annotation2D'
+/// 
+/// Body - 'SweptSolid', 'SurfaceModel', or 'Brep'
+/// representation
+/// The door body is either represented parameterically (see
+/// parametric representation) or by explicit 3D shape. The 3D shape
+/// is given by using extrusion geometry, or surface models, or Brep
+/// models within a particular shape representation. The body is used
+/// for the model view representation of the door.The following
+/// attribute values for the IfcShapeRepresentation holding
+/// this geometric representation shall be used:
+/// 
+/// RepresentationIdentifier : 'Body'
+/// RepresentationType : 'SweptSolid', 'SurfaceModel', or
+/// 'Brep'
+/// 
+/// MappedRepresentation
+/// The 'FootPrint' and 'Body' geometric representation of
+/// IfcDoor can be shared among several identical doors using
+/// the 'MappedRepresentation'. The following attribute values for
+/// the IfcShapeRepresentation holding this geometric
+/// representation shall be used:
+/// 
+/// RepresentationIdentifier : 'FootPrint', 'Body'
+/// RepresentationType : 'MappedRepresentation'
+/// 
+/// The same constraints, as given for the 'FootPrint', 'Body'
+/// representation identifiers, shall apply to the
+/// MappedRepresentation of the
+/// IfcRepresentationMap.
+/// Parameteric Representation using parameters at
+/// IfcDoorType
+/// The parameters that defines the shape of the IfcDoor,
+/// are given at the IfcDoorType and the property sets, which
+/// are included in the IfcDoorType. The IfcDoor only
+/// defines the local placement which determines the opening
+/// direction of the door. The overall size of
+/// the IfcDoor to be used to apply the lining or panel
+/// parameter provided by the IfcDoorType is determined by the
+/// IfcShapeRepresentation with the RepresentationIdentifier =
+/// 'Profile'. Only in case of an IfcDoor inserted into an
+/// IfcOpeningElement using the IfcRelFillsElement
+/// relatioship, having a horizontal extrusion (along the y-axis of
+/// the IfcDoor), the overall size is determined by the
+/// extrusion profile of the IfcOpeningElement.
+/// NOTE The OverallWidth and
+/// OverallHeight parameters are for informational purpose
+/// only.
+/// The opening direction is determined by the local placement of
+/// IfcDoor and the OperationType of the door
+/// style as shown in Figure 97.
+/// NOTE There are different definitions in
+/// various countries on what a left opening or left hung or left
+/// swing door is (same for right). Therefore the IFC definition may

+/// defined at the supertype IfcDoor.
+/// Containment Use Definition
+/// The containment use definitions relating to the
+/// IfcDoorStandardCase are defined at the supertype
+/// IfcDoor.
+/// Geometry Use Definitions:
+/// The geometric representation of IfcDoorStandardCase is
+/// given by the IfcProductDefinitionShape, allowing multiple
+/// geometric representations. Included are:
+/// Local Placement
+/// The use of local placement is defined at the supertype
+/// IfcDoor.
+/// Geometric Representations
+/// The geometric representation of IfcDoorStandardCase is
+/// defined using the following multiple shape representations for its
+/// definition:
+/// 
+/// Profile: a three-dimensional closed curve within a
+/// particular shape representation. The profile is used to apply the
+/// parameter of the parametric door representation. The profile around
+/// the edges of the opening is used to apply the door lining and door
+/// panel shape parameter.
+/// MappedRepresentation: A SweptSolid, SurfaceModel, or
+/// Brep Representation or a CSG additionally defining the 3D shape of
+/// the standard door in addition to the parametric representation by
+/// applying the IfcDoorLiningProperties and an the
+/// IfcDoorPanelProperties to the Profile representation.
+/// 
+/// Profile representation
+/// The door profile is represented by a three-dimensional closed
+/// curve within a particular shape representation. The profile is used
+/// to apply the parameter of the parametric door
+/// representation. The following attribute values for the
+/// IfcShapeRepresentation holding this geometric representation
+/// shall be used:
+/// 
+/// RepresentationIdentifier : 'Profile'
+/// RepresentationType : 'Curve3D' or 'GeometricCurveSet',
+/// in case of 'GeometricCurveSet' only a single closed curve shall be
+/// contained in the set of IfcShapeRepresentation.Items.
+/// 
+/// The following additional constraints apply to the 'Profile'
+/// representation type:
+/// 
+/// Curve: being an IfcPolyline defining a
+/// rectangle.
+/// Position: The curve shall lie in the xz plane of the
+/// object placement coordinate (the y coordinate values of the
+/// IfcCartesianPoint's shall be 0.).
+/// 
+/// Figure 98 illustrates applying the door lining parameters to the door profile shape representation.  The profile defines the outer boundary to which the door lining parameters relate as:
+/// 
+/// IfcDoorLiningProperties.LiningDepth starting at distance defined by LiningOffset going into the positive y direction.
+/// IfcDoorLiningProperties.LiningThickness offset into the inner side of the rectangle.
+/// IfcDoorLiningProperties.LiningOffset distance along the positive y direction to where the LiningDepth applies.
+/// IfcDoorLiningProperties.ThresholdThickness starting at the bottom edge of the rectangle into the inner side of the rectangle
+/// IfcDoorLiningProperties.ThresholdDepth starting at distance defined by LiningOffset going into the positive y direction.
+/// IfcDoorLiningProperties.TransomOffset starting at the bottom edge of the rectangle (along local x axis) into the inner side of the rectangle, distance provided as percentage of overall height. Distance to the centre line of the transom.

+/// IfcGrid ia a planar design
+/// grid defined in 3D space used as an aid in locating structural and
+/// design elements. The position of the grid (ObjectPlacement)
+/// is defined by a 3D coordinate system (and thereby the design grid
+/// can be used in plan, section or in any position relative to the
+/// world coordinate system). The position can be relative to the
+/// object placement of other products or grids. The XY plane of the 3D
+/// coordinate system is used to place the grid axes, which are 2D
+/// curves (for example, line, circle, trimmed curve, polyline, or composite
+/// curve).
+/// The inherited attributes Name and Description can
+/// be used to define a descriptive name of the grid and to indicate
+/// the grid's purpose. A grid is defined by (normally) two, or
+/// (in case of a triangular grid) three lists of grid axes. The
+/// following table shows some examples.
+/// A grid may support a rectangular layout (Figure 28), a radial layout (Figure 29), or a triangular layout (Figure 30).
+/// 
+/// Figure 28 — Grid rectangular layout
+/// Figure 29 — Grid radial layout

+/// HISTORY New entity in IFC Release 1.0.
+/// Informal Proposition
+/// 
+/// Grid axes, which are referenced in different lists of axes
+/// (UAxes, VAxes, WAxes) shall not be parallel.
+/// Grid axes should be defined such as there are no two grid axes
+/// which intersect twice (see Figure 31).
+/// 
+/// left side: ambiguous intersections A1 and A2, a grid containing
+/// such grid axes is not a valid design grid.
+/// right side: the conflict can be resolved by splitting one grid
+/// axis in a way, such as no ambiguous intersections exist.
+/// 
+/// Figure 31 — Grid intersections
+/// 
+/// Geometry Use Definitions
+/// The geometric representation of IfcGrid is given by the
+/// IfcProductDefinitionShape, allowing geometric
+/// representations. Included are:
+/// Local Placement
+/// The local placement for IfcGrid is defined in its
+/// supertype IfcProduct. It is defined by the
+/// IfcLocalPlacement, which defines the local coordinate system
+/// that is referenced by all geometric representations.
+/// 
+/// The PlacementRelTo relationship of
+/// IfcLocalPlacement shall point (if given) to the local
+/// placement of the same IfcSpatialStructureElement, which is
+/// used in the ContainedInStructure inverse attribute, or to a
+/// spatial structure element at a higher level, referenced by
+/// that.
+/// If the relative placement is not used, the absolute placement
+/// is defined within the world coordinate system.
+/// 
+/// Geometric Representations
+/// Currently, the use of a 2D 'FootPrint' representation of type
+/// 'GeometricCurveSet' is supported.
+/// GeometricCurveSet representation
+/// The 2D geometric representation of IfcGrid is defined
+/// using the 'GeometricCurveSet' geometry. The following attribute
+/// values should be inserted
+/// 
+/// IfcShapeRepresentation.RepresentationIdentifier =
+/// 'FootPrint'.
+/// IfcShapeRepresentation.RepresentationType =
+/// 'GeometricCurveSet' .
+/// 
+/// The following constraints apply to the 2D representation:
+/// 
+/// The IfcGeometricCurveSet shall be an (and the only)
+/// Item of the IfcShapeRepresentation. It should contain
+/// an IfcGeometricCurveSet containing subtypes of
+/// IfcCurve, each representing a grid axis. Applicable subtypes
+/// of IfcCurve are: IfcPolyline, IfcCircle,
+/// IfcTrimmedCurve (based on BaseCurve referencing
+/// IfcLine or IfcCircle). 
+/// Each subtype of IfcCurve may have a curve style
+/// assigned, using IfcAnnotationCurveOccurrence referencing
+/// IfcCurveStyle.
+/// Optionally the grid axis labels may be added as
+/// IfcTextLiteral, and they may have text styles assigned,
+/// using IfcAnnotationTextOccurrence referencing
+/// IfcTextStyle.
+/// 
+/// As shown in Figure 32, the IfcGrid defines a placement coordinate system using the ObjectPlacement. The XY plane of the coordinate system is used to place the 2D grid axes. The Representation of IfcGrid is defined using IfcProductRepresentation, referencing an IfcShapeRepresentation, that includes IfcGeometricCurveSet as Items. All grid axes are added as IfcPolyline to the IfcGeometricCurveSet.
+/// 
+/// Figure 32 — Grid layout
+///

+/// 
+/// Containment Use Definition
+/// The IfcMember, as any subtype of

+/// The IfcMember may be aggregated into an element
+/// assembly using the objectified relationship
+/// IfcRelAggregates, refering to it by its inverse attribute
+/// SELF\IfcObjectDefinition.Decomposes. Any subtype of
+/// IfcElement can be an element assembly, with
+/// IfcElementAssembly as a special focus subtype. In this
+/// case it should not be additionally contained in the project
+/// spatial hierarchy, i.e.
+/// SELF\IfcElement.ContainedInStructure should be
+/// NIL.
+/// 
+/// Geometry Use Definition
+/// The geometric representation of IfcMember is given by
+/// the IfcProductDefinitionShape, allowing multiple geometric
+/// representations. Included are:
+/// Local Placement
+/// The local placement for IfcMember is defined in its
+/// supertype IfcProduct. It is defined by the
+/// IfcLocalPlacement, which defines the local coordinate
+/// system that is referenced by all geometric representations.
+/// 
+/// The PlacementRelTo relationship of
+/// IfcLocalPlacement shall point (if given) to the local
+/// placement of the same IfcSpatialStructureElement, which is
+/// used in the ContainedInStructure inverse attribute, or to
+/// a spatial structure element at a higher level, referenced by
+/// that.
+/// If the relative placement is not used, the absolute placement
+/// is defined within the world coordinate system.
+/// 
+/// Geometric Representation
+/// Currently, the 'Axis', 'Body',
+/// and 'Box' representations are supported. The 'Box' representation
+/// includes the representation type 'BoundingBox' and is explained
+/// at IfcBuildingElement.
+/// Axis Representation
+/// The axis geometric representation of IfcMember is

+/// using the representation types 'SweptSolid', 'Clipping',
+/// 'AdvancedSweptSolid', 'MappedRepresentation', 'SurfaceModel', and
+/// 'Brep'. The representation types 'SurfaceModel' and 'Brep' are

+/// Definition from IAI: An IfcPlate is a planar and
+/// often flat part with constant thickness. A plate can be a
+/// structural part carrying loads between or beyond points of
+/// support, however it is not required to be load bearing.The
+/// location of the plate (being horizontal, vertical or sloped) is
+/// not relevant to its definition (in contrary to IfcWall and
+/// IfcSlab (as floor slab)).
+/// NOTE Plates arenormally made of steel, other
+/// metallic material, or by glass panels. However the definition of
+/// IfcPlate is material independent and specific material
+/// information shall be handled by using
+/// IfcAssociatesMaterial to assign a material specification
+/// to the IfcPlate.
+/// 
+/// NOTE Although not necessarily, plates are often add-on
+/// parts. This is represented by the IfcRelAggregates
+/// decomposition mechanism used to aggregate parts, such as
+/// IfcPlate, into a container element, e.g.
+/// IfcElementAssembly, or IfcCurtainWall.
+/// 
+/// NOTE The representation of a plate in a structural
+/// analysis model is provided by IfcStructuralSurfaceMember
+/// being part of an
+/// IfcStructuralAnalysisModel.
+/// An instance IfcPlate should preferably get its
+/// geometric representation and material assignment through the type
+/// definition by IfcPlateType assigned using the
+/// IfcRelDefinesByType relationship. This allows identical
+/// plates in a construction to be represented by the same instance
+/// of IfcPlateType.
+/// A plate may have openings, such as voids or recesses. They are
+/// defined by an IfcOpeningElement attached to the plate
+/// using the inverse relationship HasOpenings pointing to
+/// IfcRelVoidsElement. The position number of a plate as
+/// often used in steel construction is assigned through the
+/// attribute IfcElement.Tag
+/// The IFC specification provides two entities for plate
+/// occurrences:
+/// 
+/// IfcPlateStandardCase used for all occurrences of
+/// plates, that are prismatic and where the thickness parameter can
+/// be fully described by the IfcMaterialLayerSetUsage. These
+/// plates are always represented geometrically by a 'SweptSolid'
+/// geometry (or by a 'Clipping' geometry based on 'SweptSolid'), if
+/// a 3D geometric representation is assigned. In addition they have
+/// to have a corresponding IfcMaterialLayerSetUsage
+/// assigned.
+/// IfcPlate used for all other occurrences of plates,
+/// particularly for plates with changing thickness, or plates with
+/// non planar surfaces, and plates having only 'SurfaceModel' or
+/// 'Brep' geometry.
+/// 
+/// HISTORY New entity in
+/// IFC Release 2x2
+/// Type Use Definition
+/// The IfcPlate defines the occuurence of any plate,
+/// common information about plate types (or styles) is handled by
+/// IfcPlateType. The IfcPlateType (if present) may
+/// establish the commontype name, usage (or predefined) type,
+/// common set of properties, common material layer set, and common
+/// shape representations (using IfcRepresentationMap). The
+/// IfcPlateType is attached using the
+/// IfcRelDefinedByType.RelatingType objectified relationship
+/// and is accessible by the inverse IsTypedBy attribute.
+/// If no IfcPlateType is attached(i.e. if only occurrence
+/// information is given) the PredefinedType should be
+/// provided. If set to .USERDEFINED. a user defined value can be
+/// provided by the ObjectType attribute.
+/// Material Use Definition
+/// The material of the IfcPlate is defined by
+/// IfcMaterialLayerSet, or IfcMaterial and attached by
+/// the IfcRelAssociatesMaterial.RelatingMaterial. It
+/// is accessible by the inverse HasAssociations
+/// relationship.
+/// NOTE It is illegal to assign an

+/// concept.
+/// Material information can also be given at the

+/// occurrences of the same type.It is then accessible by the
+/// inverse IsTypedBy
+/// relationship pointing to IfcPlateType.HasAssociations and
+/// via IfcRelAssociatesMaterial.RelatingMaterial.
+/// Property Set Use Definition
+/// The property sets relating to the IfcPlate are defined
+/// by the IfcPropertySet and attached by the

+/// 
+/// Containment Use Definitions
+/// The IfcPlate, as any subtype of

+/// containment relationships. The first (and in most implementation
+/// scenarios mandatory) relationship is the hierachical spatial
+/// containment, the second relationship is the aggregation within
+/// anelement assembly.
+/// 
+/// TheIfcPlate is places within the project spatial
+/// hierarchy using the objectified relationship
+/// IfcRelContainedInSpatialStructure, referring to it by its
+/// inverse attribute SELF\IfcElement.ContainedInStructure.
+/// Subtypes ofIfcSpatialStructureElement are valid spatial
+/// containers, with IfcBuildingStorey being the default
+/// container.
+/// TheIfcPlate may be aggregated into an element
+/// assembly using the objectified relationship
+/// IfcRelAggregates, referring to it by its inverse attribute
+/// SELF\IfcObjectDefinition.Decomposes. Any subtype of
+/// IfcElement can be an element assembly, with
+/// IfcElementAssembly as a special focus subtype. In this
+/// case, no additional relationship to the spatial hierarchy shall
+/// be given (i.e.SELF\IfcElement.ContainedInStructure =
+/// NIL), the relationship to the spatial container is handled by the
+/// element assembly.
+/// 
+/// Geometry Use Definition
+/// The geometric representation of IfcPlate is
+/// given by the IfcProductDefinitionShape, allowing multiple
+/// geometric representations. Included are:
+/// Local Placement
+/// The local placement for IfcPlate is defined in
+/// its supertype IfcProduct. It is defined by the
+/// IfcLocalPlacement, which defines the local coordinate
+/// system that is referenced by all geometric representations.
+/// 
+/// The PlacementRelTo relationship of
+/// IfcLocalPlacement shall point (if given) to the local
+/// placement of the same IfcSpatialStructureElement, which is
+/// used in the ContainedInStructure inverse attribute, or to
+/// a spatial structure element at a higher level, referenced by
+/// that.
+/// 
+/// If the IfcPlate is part of an assembly, the
+/// PlacementRelTo relationship of IfcLocalPlacement
+/// shall point to the local placement of the container element, e.g.
+/// IfcElementAssembly,
+/// 
+/// If the relative placement is not used, the absolute placement
+/// is defined within the world coordinate system.
+/// 
+/// Geometric Representation
+/// Currently, the 'Surface',
+/// 'FootPrint', 'Body', and 'Box'
+/// representations are supported. The 'Box' representation includes
+/// the representation type 'BoundingBox' and is explained at
+/// IfcBuildingElement.

+/// for reduced Level of Detail representation).
+/// Body Representation
+/// The body representation of IfcPlate can be represented
+/// using the representation types 'SweptSolid', 'Clipping',
+/// 'MappedRepresentation', 'SurfaceModel', and 'Brep'. The
+/// representation types 'SurfaceModel' and 'Brep' are explained at

+/// Type Use Definition
+/// The IfcPlateStandardCase defines the occuurence of any
+/// plate, common information about plate types (or styles) is handled
+/// by IfcPlateType. The IfcPlateType (if present) may
+/// establish the common type name, usage (or predefined) type,
+/// common set of properties, common material layer set, and common
+/// shape representations (using IfcRepresentationMap). The
+/// IfcPlateType is attached using the
+/// IfcRelDefinedByType.RelatingType objectified relationship
+/// and is accessible by the inverse IsDefinedBy attribute.
+/// The IfcPlateStandardCase defines in addition that the
+/// IfcPlateType should have a unique
+/// IfcMaterialLayerSet, that is referenced by
+/// the IfcMaterialLayerSetUsage assigned to all
+/// occurrences of this plate type.
+/// 
+/// Figure 107 illustrates assignment of IfcMaterialLayerSetUsage and IfcMaterialLayerSet to the IfcPlateStandardCase as the plate occurrence and to the IfcPlateType. The same IfcMaterialLayerSet shall be shared by many occurrences of IfcMaterialLayerSetUsage. This relationship shall be consistent to the relationship between the IfcPlateType and the IfcPlateStandardCase.
+/// 
+///  
+/// Figure 107 — Plate type definition
+/// 
+/// Material Use Definition
+/// The material of the IfcPlateStandardCase is defined by
+/// IfcMaterialLayerSetUsage and attached by the
+/// IfcRelAssociatesMaterial.RelatingMaterial. It is
+/// accessible by the inverse HasAssociations relationship.
+/// Multi-layer plates can be represented by refering to several
+/// IfcMaterialLayer's within the IfcMaterialLayerSet
+/// that is referenced from the
+/// IfcMaterialLayerSetUsage. 
+/// Material information can also be given at the
+/// IfcPlateType, defining the common attribute data for all
+/// occurrences of the same type. It is then accessible by the
+/// inverse IsDefinedBy relationship pointing to
+/// IfcPlateType.HasAssociations and via
+/// IfcRelAssociatesMaterial.RelatingMaterial. See Type Use
+/// Definition for additional agreements for standard plates.
+/// 
+/// As shown in Figure 108, the following conventions shall be met:
+/// 
+/// The reference coordinate system is the coordinate system established by the IfcExtrudedAreaSolid.Position.
+/// The reference plane is the plane defined by the extruded profile of IfcExtrudedAreaSolid.SweptSolid. The IfcMaterialLayerSetUsage.OffsetFromReferenceLine is given as a distance from this plane.
+/// The IfcMaterialLayerSetUsage.DirectionSense defines how the IfcMaterialLayer's are assigned to the reference plane. POSITIVE means in direction to the positive z-axis of the reference coordinate system.
+/// The IfcMaterialLayerSetUsage.OffsetFromReferenceLine is the distance parallel to the reference plane and always perpendicular to the base (XY) plane of the reference coordinate system. This is independent of a potential non-perpendicular extrusion given by IfcExtrudedAreaSolid.ExtrudedDirection <> 0.,0.,1. A positive value of IfcMaterialLayerSetUsage.OffsetFromReferenceLine would then point into the positive z-axis of the reference coordinate system.
+/// The Thickness of each IfcMaterialLayer shall be the parallel distance (measured perpendicular to the base plane). The TotalThickness of the IfcMaterialLayerSet is the sum of all layer thicknesses and in case of a perpendicular extrusion identical with IfcExtrudedAreaSolid.Depth
+/// The IfcMaterialLayerSetUsage.LayerSetDirection i always AXIS3.

+/// Definition from ISO 6707-1:1989: Inclined way or floor

+/// A ramp is a vertical passageway which

+/// landing as an intermediate floor slab. A ramp normally does not
+/// include steps (stepped ramps are out of scope for this IFC

+/// The ramp is a container entity that aggregates all components
+/// of the ramp, it represents. The aggregation is handled via the
+/// IfcRelAggregates relationship, relating an IfcRamp
+/// with the related flights (IfcRampFlight) and landings
+/// (IfcSlab with type 'Landing'). Railings belonging to the
+/// ramp may be included into the aggregation as

+/// Type Use Definition
+/// IfcRamp defines the occuurence of any ramp, common

+/// Definition from ISO 6707-1:1989: Construction enclosing the building from above.
+/// The IfcRoof is a description of the total roof. It acts as a container entity, that aggregates all components of the roof, it represents. The aggregation is handled via the IfcRelAggregates relationship, relating an IfcRoof with the related roof elements, like slabs (represented by IfcSlab), rafters and purlins (represented by IfcBeam), or other included roofs, such as dormers (represented by IfcRoof).
+/// 
+/// HISTORY New Entity in IFC Release 2.0.
+/// IFC2x4 CHANGE Attribute ShapeType renamed to PredefinedType.
+/// 
+/// Property Set Use Definition:
+/// The property sets relating to the IfcRoof are defined
+/// by the IfcPropertySet and attached by the
+/// IfcRelDefinesByProperties relationship. It is accessible
+/// by the inverse IsDefinedBy relationship. The following
+/// property set definitions specific to the IfcRoof are part
+/// of this IFC release:
+/// 
+/// Pset_RoofCommon: common property set for all
+/// roof occurrences
+/// 
+/// The quantities relating to the IfcRoof are defined by
+/// the IfcElementQuantity and attached by the
+/// IfcRelDefinesByProperties relationship. It is accessible
+/// by the inverse IsDefinedBy relationship. The following
+/// base quantities are defined and should be exchanged with the
+/// IfcElementQuantity.MethodOfMeasurement = 'BaseQuantities'.
+/// Other quantities can be defined being subjected to local standard
+/// of measurement with another string value assigned to Name
+/// and a value provided for MethodOfMeasurement. Quantities
+/// shall never be assigned to the IfcRoofType.
+/// The individual quantities shall only be given at
+/// IfcRoof, it is not decomposed into the individual parts,
+/// e.g. IfcSlab as roof slabs.
+/// 
+/// Qto_RoofBaseQuantities: base quantities for
+/// all roof occurrences.
+/// 
+/// Containment Use Definition
+/// The IfcRoof, as any subtype of
+/// IfcBuildingElement, may participate in two different
+/// containment relationships. The first (and in most implementation
+/// scenarios mandatory) relationship is the hierachical spatial
+/// containment, the second (optional) relationship is the
+/// aggregation within an element assembly.
+/// 
+/// The IfcRoof is placed within the project spatial
+/// hierarchy using the objectified relationship
+/// IfcRelContainedInSpatialStructure, referring to it by its
+/// inverse attribute SELF\IfcElement.ContainedInStructure.
+/// Subtypes of IfcSpatialStructureElement are valid spatial
+/// containers, with IfcBuildingStorey being the default
+/// container.
+/// The IfcRoof may be aggregated into an element assembly
+/// using the objectified relationship IfcRelAggregates,
+/// referring to it by its inverse attribute
+/// SELF\IfcObjectDefinition.Decomposes. Any subtype of
+/// IfcElement can be an element assembly, with
+/// IfcRoof, the overall roof, as a special focus subtype. In
+/// this case it should not be additionally contained in the project
+/// spatial hierarchy, i.e.
+/// SELF\IfcElement.ContainedInStructure should be NIL.
+/// 
+/// NOTE A roof contained in another roof could
+/// be the representation of a dormer.
+/// The IfcRoof may be an aggregate i.e. being composed by
+/// other elements and acting as an assembly using the objectified
+/// relationship IfcRelAggregates, referring to it by its
+/// inverse attribute SELF\IfcObjectDefinition.IsDecomposedBy.
+/// Components of a roof are described by instances of subtypes of
+/// IfcBuildingElement (e.g. IfcSlab, IfcBeam,
+/// IfcColumn, IfcBuildingElementPart) that are
+/// aggregated to form a complex roof. In this case, the contained
+/// elements should not be additionally contained in the project
+/// spatial hierarchy, i.e. the inverse attribute
+/// SELF\IfcElement.ContainedInStructure of the aggregated
+/// elements should be NIL.
+/// 
+/// Figure 118 illustrates roof containment, where only the IfcRoof as the aggregate
+/// is included in the spatial structure.
+/// 
+/// Figure 118 — Roof containment
+/// 
+/// Geometry Use Definitions:
+/// The geometric representation of IfcRoof is given by the
+/// IfcProductDefinitionShape, allowing multiple geometric
+/// representations. Independent geometric representations should
+/// only be used when the IfcRoof is not defined as an
+/// aggregate. If defined as an aggregate, the geometric
+/// representation is the sum of the representation of the components
+/// within the aggregate.
+/// NOTE View definitions and implementer
+/// agreements may restrict the IfcRoof to not have an
+/// independent geometry, but to always require aggregated elements
+/// to represent the shape of the roof.
+/// NOTE If the IfcRoof has aggregated elements to
+/// represent the shape of the roof, then only those elements shall
+/// have openings, not the IfcRoof
+/// itself.
+/// Local Position
+/// The local placement for IfcRoof is defined in its
+/// supertype IfcProduct. It is defined by the
+/// IfcLocalPlacement, which defines the local coordinate
+/// system that is referenced by all geometric representations.
+/// 
+/// The PlacementRelTo relationship of
+/// IfcLocalPlacement shall point (if given) to the local
+/// placement of the same IfcSpatialStructureElement that is
+/// used in the ContainedInStructure inverse attribute or to a
+/// referenced spatial structure element at a higher level..
+/// If the relative placement is not used, the absolute placement
+/// is defined within the world coordinate system.
+/// 
+/// If the LocalPlacement is given for the IfcRoof,
+/// then all components, which are aggregated to the roof should use
+/// this placement as their relative placement.
+/// Geometric Representation
+/// The IfcRoof may have an independent geometric representation
+/// or may be an aggregate with elements holding the geometric
+/// representation of the roof.
+/// Geometric representation by own shape
+/// representation
+/// If the IfcRoof has no components defined (empty set of
+/// SELF\IfcObject.IsDecomposedBy) then the IfcRoof may
+/// be represented by an independent IfcShapeRepresentation.
+/// The following attribute values for the IfcShapeRepresentation
+/// holding this geometric representation shall be used:
+/// 
+/// RepresentationIdentifier : 'Body'
+/// RepresentationType : 'SweptSolid', 'Clipping',
+/// 'SurfaceModel', or 'Brep'
+/// 
+/// Geometric representation by aggregated elements
+/// If the IfcRoof has components (referenced by
+/// SELF\IfcObject.IsDecomposedBy) then no independent
+/// geometric representation shall defined for the IfcRoof.
+/// The IfcRoof is then geometrically represented by the
+/// geometric representation of its components. The components are
+/// accessed via
+/// SELF\IfcObject.IsDecomposedBy[1].RelatedObjects. The
+/// geometric representations that are supported for the aggregated
+/// elements are defined with each element. See geometric use
+/// definition for IfcSlab, IfcBeam, IfcColumn,
+/// IfcBuildingElementPart and other subtypes of
+/// IfcBuildingElement.

+/// HISTORY New entity in IFC Release 2.0, it is a merger of the two previous entities
+/// IfcFloor, IfcRoofSlab, introduced in IFC Release 1.0
+/// 
+/// Type Use Definition
+/// The IfcSlab defines the occurrence of any slab, common
+/// information about slab types (or styles) is handled by
+/// IfcSlabType. The IfcSlabType (if present) may
+/// establish the commontype name, usage (or predefined) type,
+/// common set of properties, common material layer set, and common
+/// shape representations (using IfcRepresentationMap). The
+/// IfcSlabType is attached using the
+/// IfcRelDefinedByType.RelatingType objectified relationship
+/// and is accessible by the inverse IsTypedBy attribute.
+/// If no IfcSlabType is attached(i.e. if only occurrence
+/// information is given) the PredefinedType should be
+/// provided. Values of the enumeration are .FLOOR. (the default),
+/// .ROOF., .LANDING., .BASESLAB. If set to .USERDEFINED. a user
+/// defined value can be provided by the ObjectType
+/// attribute.
+/// Material Use Definition
+/// The material of the IfcSlab is defined by
+/// IfcMaterialLayerSet, or IfcMaterial and attached by
+/// the IfcRelAssociatesMaterial.RelatingMaterial. It
+/// is accessible by the inverse HasAssociations relationship.
+/// Multi-layer slabs can be represented by referring to several
+/// IfcMaterialLayer's within the
+/// IfcMaterialLayerSet.
+/// NOTE It is illegal to assign an
+/// IfcMaterialLayerSetUsage to an IfcSlab. Only the
+/// subtype IfcSlabStandardCase supports this
+/// concept.
+/// NOTE Prismatic slabs, where the main face of
+/// the slab is extruded along the slab thickness, are exchanged as
+/// IfcSlabStandardCase, The material for
+/// IfcSlabStandardCase shall be defined
+/// byIfcMaterialLayerSetUsage. Multi-layer slabs can be
+/// represented by referring to several IfcMaterialLayer's
+/// within the IfcMaterialLayerSet.
+/// Material information can also be given at the
+/// IfcSlabType, defining the common attribute data for all
+/// occurrences of the same type.It is then accessible by the
+/// inverse IsTypedBy
+/// relationship pointing to IfcSlabType.HasAssociations and
+/// via IfcRelAssociatesMaterial.RelatingMaterial.
+/// Property Set Use Definition:
+/// The property sets relating to the IfcSlab are defined
+/// by the IfcPropertySet and attached by the
+/// IfcRelDefinesByProperties relationship. It is accessible
+/// by the inverse IsDefinedBy relationship. The following
+/// property set definitions specific to the IfcSlab are part
+/// of this IFC release:
+/// 
+/// Pset_SlabCommon: common property set for all
+/// slab occurrences
+/// 
+/// Property sets can also be given at the IfcSlabType,
+/// defining the common property data for all occurrences of the same
+/// type.It is then accessible by the inverse IsTypedBy relationship pointing to
+/// IfcSlabType.HasPropertySets. If both are given, then the
+/// properties directly assigned to IfcSlab overrides the
+/// properties assigned to IfcSlabType.
+/// Quantity Use Definition
+/// The quantities relating to the IfcSlab and
+/// IfcSlabStandardCase are defined by the
+/// IfcElementQuantity and attached by the
+/// IfcRelDefinesByProperties relationship. It is accessible
+/// by the inverse IsDefinedBy relationship. The following
+/// base quantities are defined and should be exchanged with the
+/// IfcElementQuantity.Name = 'BaseQuantities'. Other
+/// quantities can be defined being subjected to local standard of
+/// measurement with another string value assigned to Name and
+/// a value provided for MethodOfMeasurement. Quantities shall
+/// never be assigned to the IfcSlabType.
+/// 
+/// Qto_SlabBaseQuantities: base quantities for
+/// all slab occurrences.
+/// 
+/// Containment Use Definition
+/// The IfcSlab, as any subtype of
+/// IfcBuildingElement, may participate in two different
+/// containment relationships. The first (and in most implementation
+/// scenarios mandatory) relationship is the hierarchical spatial
+/// containment, the second (optional) relationship is the
+/// aggregation within anelement assembly.
+/// 
+/// TheIfcSlab is places within the project spatial
+/// hierarchy using the objectified relationship
+/// IfcRelContainedInSpatialStructure, referring to it by its
+/// inverse attribute SELF\IfcElement.ContainedInStructure.
+/// Subtypes ofIfcSpatialStructureElement are valid spatial
+/// containers, with IfcBuildingStorey being the default
+/// container.
+/// TheIfcSlab may be aggregated into an element assembly
+/// using the objectified relationship IfcRelAggregates,
+/// referring to it by its inverse attribute
+/// SELF\IfcObjectDefinition.Decomposes. Any subtype of
+/// IfcElement can be an element assembly, with
+/// IfcElementAssembly as a special focus subtype.
+/// In this case it should not be additionally contained in the
+/// project spatial hierarchy,
+/// i.e.SELF\IfcElement.ContainedInStructure should be
+/// NIL.
+/// 
+/// The IfcSlabmay also be an aggregate i.e. being
+/// composed by other elements and acting as an assembly using the
+/// objectified relationship IfcRelAggregates, referring to it
+/// by its inverse attribute
+/// SELF\IfcObjectDefinition.IsDecomposedBy. Components of a
+/// slab are described by instances of subtypes of
+/// IfcBuildingElement, with IfcBuildingElementPart as
+/// a special focus subtype that are aggregated to form a complex
+/// slab. In this case, the contained elements should not be
+/// additionally contained in the project spatial hierarchy, i.e. the
+/// inverse attribute SELF\IfcElement.ContainedInStructure of
+/// IfcBuildingElementPart (or other subtypes of
+/// IfcBuildingElement) should be NIL.
+/// Geometry Use Definition
+/// The geometric representation of IfcSlab is given by the
+/// IfcProductDefinitionShape, allowing multiple geometric
+/// representation. Included are:
+/// NOTE. If the IfcSlab is of type Landing
+/// and is used within an IfcStair or IfcRamp, the
+/// special agreements to handle stair and ramp geometry will also
+/// affect the geometric representation of the
+/// IfcSlab.
+/// Local Placement
+/// The local placement for IfcSlab is defined in its
+/// supertype IfcProduct. It is defined by the
+/// IfcLocalPlacement, which defines the local coordinate
+/// system that is referenced by all geometric representations.
+/// 
+/// The PlacementRelTo relationship of
+/// IfcLocalPlacement shall point (if given) to the placement
+/// of the local placement of the same
+/// IfcSpatialStructureElement that is used in the
+/// ContainedInStructure inverse attribute or to a referenced
+/// spatial structure element at a higher level.
+/// If the IfcSlab is of type Landing and is used by an
+/// IfcStair or IfcRamp, and this container class
+/// defines its own local placement, then the PlacementRelTo
+/// relationship of IfcLocalPlacement shall point (if given)
+/// to the local placement of the aggregate.
+/// If the relative placement is not used, the absolute placement
+/// is defined within the world coordinate system.
+/// 
+/// Geometric Representation
+/// Currently, the 'Surface',
+/// 'FootPrint', 'Body', and 'Box'
+/// representations are supported. The 'Box' representation includes
+/// the representation type 'BoundingBox' and is explained at

+/// Definition from IAI: The IfcStructuralAnalysisModel is used to assemble all information needed to represent a structural analysis model.  It encompasses certain general properties (such as analysis type), references to all contained structural members, structural supports or connections, as well as loads and the respective load results.
+/// 
+/// Important functionalities for the description of an analysis model are derived from existing IFC entities:
+/// 
+/// From IfcSystem it inherits the ability to couple the analysis model via IfcRelServicesBuildings to one or more IfcBuildings as necessary.
+///   From IfcGroup it inherits the inverse attribute IsGroupedBy, pointing to the relationship class IfcRelAssignsToGroup.  This allows to group structural members (instances of IfcStructuralMember), and supports (instances of IfcStructuralConnection) which belong to a specific analysis model.
+///   NOTE:  Loads (as instances of IfcStructuralAction) are not included through IsGroupedBy.  Loads are assigned through the LoadedBy attribute relationship, using load groups as a grouping mechanism.  Only top-level load groups should be referenced via LoadedBy, i.e. load combinations if any load combinations exist, or load cases if no load combinations exist in this analysis model.
+///   NOTE:  Results (as instances of IfcStructuralReaction) are not included through IsGroupedBy.  Results are assigned through the HasResults attribute relationship, using result groups as a grouping mechanism.
+/// 
+/// From IfcObject it inherits the inverse attribute IsDecomposedBy pointing to the relationship class IfcRelNests. It provides the hierarchy between the separate (partial) analysis models.
+/// 
+/// HISTORY: New entity in IFC 2x2.
+/// 
+/// IFC 2x4 change:  Attribute SharedPlacement and informal propositions added, allowing for easy retrieval of the common object placement and for specification of the analysis model's coordiante system before any structural item is instantiated.  WHERE rule added.
+/// 
+/// Informal propositions:
+/// 
+/// If one or more structural item (instance of a subtype of IfcStructuralItem) is grouped into an IfcStructuralAnalysisModel, the attribute SharedPlacement shall be provided with a value.
+///   The ObjectPlacements of all structural items which are grouped into the same instance of IfcStructuralAnalysisModel shall refer to the same instance of IfcObjectPlacement as IfcStructuralAnalysisModel.SharedPlacement.
+/// 
+/// NOTE  This rule is necessary to achieve consistent topology representations.  The topology representations of structural items in an analysis model are meant to share vertices and edges und must therefore have the same object placement.

+/// Containment Use Definition
+/// The IfcWall (and the subtype

+/// containment relationships. The first (and in most implementation
+/// scenarios mandatory) relationship is the hierarchical spatial
+/// containment, the second (optional) relationship is the
+/// aggregation within anelement assembly.
+/// 
+/// The IfcWall is places within the project spatial
+/// hierarchy using the objectified relationship
+/// IfcRelContainedInSpatialStructure, referring to it by its
+/// inverse attribute SELF\IfcElement.ContainedInStructure.
+/// Subtypes ofIfcSpatialStructureElement are valid spatial
+/// containers, with IfcBuildingStorey being the default
+/// container.
+/// TheIfcWall may be aggregated into an element assembly
+/// using the objectified relationship IfcRelAggregates,
+/// referring to it by its inverse attribute
+/// SELF\IfcObjectDefinition.Decomposes. Any subtype of
+/// IfcElement can be an element assembly, with
+/// IfcElementAssembly as a special focus subtype.
+/// In this case the wall should not be additionally contained in the
+/// project spatial hierarchy,
+/// i.e.SELF\IfcElement.ContainedInStructure should be
+/// NIL.
+/// 
+/// TheIfcWallmay also be an aggregate i.e. being
+/// composed by other elements and acting as an assembly using the
+/// objectified relationship IfcRelAggregates, referring to it
+/// by its inverse attribute
+/// SELF\IfcObjectDefinition.IsDecomposedBy. Components of a
+/// wall are described by instances of IfcBuildingElementPart
+/// that are aggregated to form a complex wall.
+/// In this case, the containedIfcBuildingElementPart's

+/// Definition form ISO 6707-1:1989: Construction for
+/// closing a vertical or near vertical opening in a wall or pitched
+/// roof that will admit light and may admit fresh air.
+/// The window is a building element
+/// that is predominately used to provide natural light and fresh
+/// air. It includes vertical and horizontal opening (e.g. skylights
+/// or light domes). It includes constructions with swinging,
+/// pivoting, sliding, or revolving panels and fixed panels. A window
+/// consists of a lining and one or several panels.
+/// The IfcWindow defines a particular occurrence of a
+/// window inserted in the spatial context of a project. A window
+/// can:
+/// 
+/// be inserted into an IfcOpeningElement using the
+/// IfcRelFillsElement relationship, , then the IfcDoor
+/// has an inverse attribute FillsVoids provided,
+/// 
+/// NOTE View definitions or
+/// implementer agreements may restrict the relationship to only
+/// include one window (or door) into one opening.
+/// 
+/// be part of an element assembly, often an
+/// IfcCurtainWall, using the IfcRelAggregates
+/// relationship, then the inverse attribute Decomposes is
+/// provided.
+/// or be a "free standing" window, then the IfcWindow has
+/// no inverse attributes FillsVoids or Decomposes
+/// provided.
+/// 
+/// The IFC specification provides two entities for window
+/// occurrences:
+/// 
+/// IfcWindowStandardCase used for all occurrences of
+/// windows, that have a 'Profile' shape representation defined to
+/// which a set of shape parameters for lining and framing properties
+/// apply. Additionally it requires the provision of an
+/// IfcWindowType that references one
+/// IfcWindowLiningProperties and on to many
+/// IfcWindowPanelProperties.
+/// 
+/// NOTE see
+/// IfcWindowStandardCase for all specific constraints imposed
+/// by this subtype.
+/// 
+/// IfcWindow used for all other occurrences of windows,
+/// particularly for windows having only 'Brep', or 'SurfaceModel'
+/// geometry without applying shape parameters.
+/// 
+/// The actual parameter of the window and/or its shape is defined
+/// at the IfcWindow as the occurrence definition (or project
+/// instance), or by the IfcWindowType as the specific definition (or
+/// project type). The following parameters are given:
+/// 
+/// at the IfcWindow or IfcWindowStandardCase for
+/// occurrence specific parameters. The IfcWindow
+/// specifies:
+/// 
+/// the window width and height
+/// the window opening direction (by the y-axis of the
+/// ObjectPlacement)
+/// 
+/// at the IfcWindowType to
+/// which the IfcWindow is related by the inverse relationship
+/// IsDefinedBy pointing to IfcRelDefinesByType, for
+/// type parameters common to all occurrences of the same type.
+/// 
+/// the partitioning type (single panel, double panel, tripel
+/// panel, more panels)
+/// the operation type (swing, tilt and turn, pivot revolve,
+/// fixed case ment, etc.)
+/// the window panel hinge side (by using two different styles
+/// for right and left opening windows)
+/// the construction material type
+/// the particular attributes for the lining by the

+/// IfcWindowPanelProperties
+/// 
+/// HISTORY New entity in IFC Release 1.0.
+/// IFC2x4 CHANGE The attributes PredefinedType and OperationType are added, the applicable type object has been changed to IfcDoorType.
+/// 
+/// Material Use Definition
+/// The material of the IfcWindow is defined by the
+/// IfcMaterialConstituentSet or as fall back by
+/// IfcMaterial and attached by the
+/// IfcRelAssociatesMaterial.RelatingMaterial. It is
+/// accessible by the inverse HasAssociations
+/// relationship.
+/// The following keywords for
+/// IfcMaterialConstituentSet.MaterialConstituents[n].Name
+/// shall be used:
+/// 
+/// 'Lining' - to indicate that the material constituent applies
+/// to to the window lining
+/// 'Framing' - to indicate that the material constituent applies
+/// to to the window panel(s), if not provided, the 'Lining' material
+/// information applied to panel(s) as well
+/// 'Glazing' - to indicate that the material constituent applies
+/// to to the glazing part
+/// 
+/// If the fall back single IfcMaterial is referenced, it
+/// applies to the lining and framing of the window.
+/// Property Set Use Definition:
+/// The property sets relating to the IfcWindow are defined
+/// by the IfcPropertySet and attached by the
+/// IfcRelDefinesByProperties relationship. It is accessible
+/// by the inverse IsDefinedBy relationship. The following
+/// property set definitions specific to the IfcWindow are
+/// part of this IFC release:
+/// 
+/// Pset_WindowCommon: common property set for all
+/// window occurrences
+/// Pset_DoorWindowGlazingType: specific property
+/// set for the glazing properties of the window glazing, if
+/// available
+/// Pset_DoorWindowShadingType: specific property

+/// 
+/// Quantity Use Definition
+/// The quantities relating to the IfcWindow are defined by
+/// the IfcElementQuantity and attached by the
+/// IfcRelDefinesByProperties relationship. It is accessible
+/// by the inverse IsDefinedBy relationship. The following
+/// base quantities are defined and should be exchanged with the
+/// IfcElementQuantity.Name = 'BaseQuantities'. Other
+/// quantities can be defined being subjected to local standard of
+/// measurement with another string value assigned to
+/// MethodOfMeasurement. Quanties shall be never assigned to
+/// the IfcWindowStyle.
+/// 
+/// Qto_WindowBaseQuantities: base quantities for
+/// all window occurrences.
+/// 
+/// Containment Use Definition
+/// 
+/// The IfcWindow, as any subtype of
+/// IfcBuildingElement, may participate in two different
+/// containment relationships. The first (and in most implementation
+/// scenarios mandatory) relationship is the hierachical spatial
+/// containment, the second (optional) relationship is the
+/// aggregation within anelement assembly.
+/// 
+/// The IfcWindow is placed within the project spatial
+/// hierarchy using the objectified relationship
+/// IfcRelContainedInSpatialStructure, refering to it by its
+/// inverse attribute SELF\IfcElement.ContainedInStructure.
+/// Subtypes ofIfcSpatialStructureElement are valid spatial
+/// containers, with IfcBuildingStorey being the default
+/// container.
+/// The IfcWindow may be aggregated into an element
+/// assembly using the objectified relationship
+/// IfcRelAggregates, refering to it by its inverse attribute
+/// SELF\IfcObjectDefinition.Decomposes. Windows may be part
+/// of an IfcCurtainWall as a special focus subtype. In this
+/// case it should not be additionally contained in the project
+/// spatial hierarchy,
+/// i.e.SELF\IfcElement.ContainedInStructure should be
+/// NIL.
+/// 
+/// Figure 141 illustrates window containment.
+/// NOTE The containment shall be defined independently of the filling relationship, that is, even if the IfcWindow is a filling of an opening established by IfcRelFillsElement, it is also contained in the spatial structure by an IfcRelContainedInSpatialStructure.
+/// 
+/// Figure 141 — Window containment
+/// 
+/// Geometry Use Definitions:
+/// The geometric representation of IfcWindow is given by
+/// the IfcProductDefinitionShape, allowing multiple geometric
+/// representation. The IfcWindow, in case of an occurrence
+/// object, gets its parameter and shape from the
+/// IfcWindowType. If an IfcRepresentationMap (a block
+/// definition) is defined for the IfcWindowType, then the
+/// IfcWindow inserts it through the IfcMappedItem
+/// (refered to by IfcShapeRepresentation.Items).
+/// Local Placement
+/// The local placement for IfcWindow is defined in its
+/// supertype IfcProduct. It is defined by the
+/// IfcLocalPlacement, which defines the local coordinate
+/// system that is referenced by all geometric representations.
+/// 
+/// The PlacementRelTo relationship of
+/// IfcLocalPlacement shall point to the local placement of
+/// the same element (if given), in which the IfcWindow is
+/// used as a filling (normally an IfcOpeningElement), as
+/// provided by the IfcRelFillsElement relationship.
+/// If the IfcWindow is not inserted into an
+/// IfcOpeningElement, then the PlacementRelTo
+/// relationship of IfcLocalPlacement shall point (if given)
+/// to the local placement of the same
+/// IfcSpatialStructureElement that is used in the
+/// ContainedInStructure inverse attribute or to a referenced
+/// spatial structure element at a higher level.
+/// If the relative placement is not used, the absolute placement
+/// is defined within the world coordinate system.
+/// 
+/// Geometric Representation
+/// Thegeometric representation of IfcWindow is defined
+/// using the following (potentiallymultiple)
+/// IfcShapeRepresentation's for its
+/// IfcProductDefinitionShape:
+/// 
+/// Profile: A'Curve3D'
+/// consisting of a single losed curve defining the outer boundary of
+/// the window (lining). Thewindow parametric representation uses
+/// this profile in order to apply thewindow lining and panel
+/// parameter. If not provided, the profile of the
+/// IfcOpeningElement is taken.
+/// FootPrint: A 'GeometricCurveSet', or 'Annotation2D'
+/// representation defining the 2D shape of thewindow
+/// Body: A 'SweptSolid', 'SurfaceModel', or 'Brep'
+/// representation defining the 3D shape of thewindow.
+/// 
+/// In addition the parametric representation of a
+/// (limited)window shape is available by applying the parameters
+/// fromIfcWindowType
+/// referencingIfcWindowLiningProperties
+/// andIfcWindowPanelProperties. The purpose of the parameter
+/// is described at those entities and below (parametric
+/// representation).
+/// Profile -'Curve3D' representation
+/// Thewindow profile is represented by a three-dimensional
+/// closed curve within a particular shape representation. The
+/// profile is used to apply the parameter of the parametricwindow
+/// representation.The following attribute values for the
+/// IfcShapeRepresentation holding this geometric
+/// representation shall be used:
+/// 
+/// RepresentationIdentifier : 'Profile'
+/// RepresentationType : 'Curve3D', only a single closed
+/// curve shall be contained in the set of
+/// IfcShapeRepresentation.Items.
+/// 
+/// A 'Profile' representation has to be provided if:
+/// 
+/// a parametric representation shall be applied to the
+/// windowAND
+/// 
+/// the window is 'free standing', or
+/// the opening into which the window is inserted is not extruded
+/// horizontally (i.e. where the opening profile does not match the
+/// window profile)
+/// 
+/// FootPrint -'GeometricCurveSet' or 'Annotation2D'
+/// representation
+/// Thewindow foot print is represented by a set of
+/// two-dimensionalcurves (or in case of 'Annotation2D' additional
+/// hatching and text) within a particular shape representation. The
+/// foot print is used for the plan view representation of
+/// thewindow.The following attribute values for the
+/// IfcShapeRepresentation holding this geometric
+/// representation shall be used:
+/// 
+/// RepresentationIdentifier : 'FootPrint'
+/// RepresentationType : 'GeometricCurveSet', or
+/// 'Annotation2D'
+/// 
+/// Body - 'SweptSolid', 'SurfaceModel', or 'Brep'
+/// representation
+/// Thewindow body is either represented parameterically (see
+/// parametric representation) or by explicit 3D shape. The 3D shape
+/// is given by using extrusion geometry, or surface models, or Brep
+/// models within a particular shape representation. The body is used
+/// for the model view representation of thewindow.The following
+/// attribute values for the IfcShapeRepresentation holding
+/// this geometric representation shall be used:
+/// 
+/// RepresentationIdentifier : 'Body'
+/// RepresentationType : 'SweptSolid', 'SurfaceModel', or
+/// 'Brep'
+/// 
+/// MappedRepresentation
+/// The 'FootPrint' and 'Body' geometric representation
+/// ofIfcWindow can be shared among several identicalwindows
+/// using the 'MappedRepresentation'. The following attribute values
+/// for the IfcShapeRepresentation holding this geometric
+/// representation shall be used:
+/// 
+/// RepresentationIdentifier : 'FootPrint', 'Body'
+/// RepresentationType : 'MappedRepresentation'
+/// 
+/// The same constraints, as given for the 'FootPrint', 'Body'
+/// representation identifiers, shall apply to the
+/// MappedRepresentation of the
+/// IfcRepresentationMap.
+/// Parameteric Representation using parameters at
+/// IfcWindowType
+/// The parameters, which define the shape of the
+/// IfcWindow, are given at the IfcWindowType and the
+/// property sets, which are included in the IfcWindowType.
+/// The IfcWindow only defines the local placement.
+/// The overall size of the IfcWindow to
+/// be used to apply the lining or panel parameter provided by the
+/// IfcWindowType is determined by the IfcShapeRepresentation
+/// with the RepresentationIdentifier = 'Profile'. Only in case of an
+/// IfcWindow inserted into an IfcOpeningElement using
+/// the IfcRelFillsElement relatioship, having a horizontal
+/// extrusion (along the y-axis of the IfcDoor), the overall
+/// size is determined by the extrusion profile of the
+/// IfcOpeningElement.
+/// 
+/// Figure 142 illustrates the insertion of a window into the IfcOpeningElement by creating an instance of
+/// IfcWindow with PartitioningType = DoublePanelHorizontal. The parameters OverallHeight and OverallWidth show the extent of the window in the positive Z and X axis of the local placement of the window. The lining and the transom are created by the given parameters.

+/// Window opening operation by window type
+/// The parameters that defines the shape of the IfcWindow,
+/// are given at the IfcWindowType and the property sets,
+/// which are included in the IfcWindowType. The
+/// IfcWindow only defines the local placement which
+/// determines the opening direction of the window. The overall

+/// itsIfcWindowType.PartitioningType. Each window panel has
+/// its own operation type, provided by
+/// IfcWindowPanelProperties.OperationType. All window panels
+/// are assumed to open into the same direction (if relevant for the
+/// particular window panel operation. The hindge side (whether a

+/// IfcWindowPanelProperties.OperationType.
+/// NOTE There are different conventions in
+/// different countries on how to show the symbolic presentation of
+/// the window panel operation (the "triangles"). Either as seen from
+/// the exterior, or from the interior side. The following figures
+/// show the symbolics from the exterior side (the convention as used
+/// predominately in Europe).
+/// 
+/// Figure 144 illustrates window operation types.
+/// 
+/// The window panel (for side hung windows) opens always

+/// 
+/// If the window should open to the other side, then the

+/// Definition from ISO 6707-1:1989: Structural member designed to carry loads between or beyond points of support, usually narrow in relation to its length and horizontal or nearly so.
+/// 
+/// An IfcBeam is a horizontal, or nearly horizontal, structural member that is capable of withstanding load primarily by resisting bending. It represents such a member from an architectural point of view. It is not required to be load bearing.
+/// 
+/// NOTE  The representation of a beam in a structural analysis model is provided by
+/// IfcStructuralCurveMember being part of an IfcStructuralAnalysisModel.
+/// 
+/// NOTE  For any longitudial structural member, not constrained to be predominately horizontal nor vertical, or where this semantic information is irrelevant, the entity IfcMember should be used.
+/// 
+/// The IFC specification provides two entities for beam occurrences:
+/// 
+/// IfcBeamStandardCase used for all occurrences of beams, that have a profile defined that is swept along a directrix. The profile might be changed uniformly by a taper definition along the directrix. The profile parameter and its cardinal point of insertion can be fully described by the IfcMaterialProfileSetUsage. These beams are always represented geometricly by an 'Axis' and a 'SweptSolid' or 'AdvancedSweptSolid' shape representation (or by a 'Clipping' geometry based on the swept solid), if a 3D geometric representation is assigned. In addition they have to have a corresponding IfcMaterialProfileSetUsage assigned.
+/// NOTE  View definitions and implementer agreements may further constrain the applicable geometry types, for example, by excluding tapering from an IfcBeamStandardCase implementation.
+/// 
+/// IfcBeam used for all other occurrences of beams, particularly for beams with changing profile sizes along the extrusion, or beams defined by non-linear extrusion, or beams having only 'Brep', or 'SurfaceModel' geometry.
+/// 
+/// HISTORY New entity in IFC Release 1.0
+/// 
+/// Type Use Definition
+/// IfcBeam defines the occuurence of any beam, common
+/// information about beam types (or styles) is handled by
+/// IfcBeamType. The IfcBeamType (if present) may
+/// establish the common type name, usage (or predefined) type,
+/// common material layer set, common set of properties and common
+/// shape representations (using IfcRepresentationMap). The
+/// IfcBeamType is attached using the
+/// IfcRelDefinedByType.RelatingType objectified relationship
+/// and is accessible by the inverse IsTypedBy attribute.
+/// If no IfcBeamType is attached (i.e. if only occurrence
+/// information is given) the PredefinedType should be provided.
+/// If set to .USERDEFINED. a user defined value can be provided by the
+/// ObjectType attribute.
+/// Material Use Definition
+/// The material of the IfcBeam is defined by the
+/// IfcMaterialProfileSet or as fallback by IfcMaterial
+/// and attached by the
+/// IfcRelAssociatesMaterial.RelatingMaterial. It is
+/// accessible by the inverse HasAssociations relationship.
+/// Note It is illegal to assign an
+/// IfcMaterialProfileSetUsage to an IfcBeam. Only the
+/// subtype IfcBeamStandardCase supports this
+/// concept.
+/// Material information can also be given at the
+/// IfcBeamType, defining the common attribute data for all
+/// occurrences of the same type. It is then accessible by the inverse
+/// IsTypedBy relationship pointing
+/// to IfcBeamType.HasAssociations and via
+/// IfcRelAssociatesMaterial.RelatingMaterial to
+/// IfcMaterialProfileSet or IfcMaterial. If both are
+/// given, then the material directly assigned to IfcBeam
+/// overrides the material assigned to IfcBeamType.
+/// Property Set Use Definition
+/// The property sets relating to the IfcBeam are defined by
+/// the IfcPropertySet and attached by the
+/// IfcRelDefinesByProperties relationship. It is accessible by
+/// the inverse IsDefinedBy relationship. The following property
+/// set definitions specific to the IfcBeam are part of this IFC
+/// release:
+/// 
+/// Pset_BeamCommon: common property set for all
+/// beam occurrences
+/// 
+/// Property sets can also be given at the IfcBeamType,
+/// defining the common property data for all occurrences of the same
+/// type. It is then accessible by the inverse IsTypedBy relationship pointing to
+/// IfcBeamType.HasPropertySets. If both are given, then the
+/// properties directly assigned to IfcBeam overrides the
+/// properties assigned to IfcBeamType.
+/// Quantity Use Definition
+/// The quantities relating to the IfcBeam are defined by the
+/// IfcElementQuantity and attached by the
+/// IfcRelDefinesByProperties relationship. It is accessible by
+/// the inverse IsDefinedBy relationship. The following base
+/// quantities are defined and should be exchanged with the
+/// IfcElementQuantity.Name = 'BaseQuantities'. Other quantities
+/// can be defined being subjected to local standard of measurement
+/// with another string value assigned to MethodOfMeasurement.
+/// Quanties shall be never assigned to the IfcBeamType.
+/// 
+/// Qto_BeamBaseQuantities: base quantities for all
+/// beam occurrences.
+/// 
+/// Containment Use Definition
+/// The IfcBeam, as any subtype of IfcBuildingElement,
+/// may participate in two different containment relationships. The
+/// first (and in most implementation scenarios mandatory) relationship
+/// is the hierachical spatial containment, the second (optional)
+/// relationship is the aggregation within an element assembly.
+/// 
+/// The IfcBeam is places within the project spatial
+/// hierarchy using the objectified relationship
+/// IfcRelContainedInSpatialStructure, refering to it by its
+/// inverse attribute SELF\IfcElement.ContainedInStructure.
+/// Subtypes of IfcSpatialStructureElement are valid spatial
+/// containers, with IfcBuildingStorey being the default
+/// container.
+/// The IfcBeam may be aggregated into an element assembly
+/// using the objectified relationship IfcRelAggregates,
+/// refering to it by its inverse attribute
+/// SELF\IfcObjectDefinition.Decomposes. Any subtype of
+/// IfcElement can be an element assembly, with
+/// IfcElementAssembly as a special focus subtype. In this case
+/// it should not be additionally contained in the project spatial
+/// hierarchy, i.e. SELF\IfcElement.ContainedInStructure should
+/// be NIL.
+/// 
+/// Geometry Use Definition
+/// The geometric representation of IfcBeam is given by the
+/// IfcProductDefinitionShape, allowing multiple geometric
+/// representations. Included are:
+/// Local Placement
+/// The local placement for IfcBeam is defined in its
+/// supertype IfcProduct. It is defined by the
+/// IfcLocalPlacement, which defines the local coordinate system
+/// that is referenced by all geometric representations.
+/// 
+/// The PlacementRelTo relationship of
+/// IfcLocalPlacement shall point (if given) to the local
+/// placement of the same IfcSpatialStructureElement, which is
+/// used in the ContainedInStructure inverse attribute, or to a
+/// spatial structure element at a higher level, referenced by that.
+/// 
+/// Exception: If the IfcBeam is part of an assembly, the
+/// PlacementRelTo relationship of IfcLocalPlacement
+/// shall point to the local placement of the container element, e.g.
+/// IfcElementAssembly,
+/// 
+/// If the relative placement is not used, the absolute placement
+/// is defined within the world coordinate system.
+/// 
+/// Geometric Representation
+/// Currently, the 'Axis', 'Body', and
+/// 'Box' representations are supported. The 'Box' representation
+/// includes the representation type 'BoundingBox' and is explained at
+/// IfcBuildingElement.

+/// using the 'Axis' representation.
+///

+/// length.
+/// Body Representation
+/// The body representation of IfcBeam can be represented
+/// using the representation types 'SweptSolid', 'Clipping',
+/// 'AdvancedSweptSolid', 'MappedRepresentation', 'SurfaceModel', and

+/// Definition from IAI: The IfcBuildingElementProxy
+/// is a proxy definition that provides the same functionality as an
+/// IfcBuildingElement, but without having a predefined meaning
+/// of the special type of building element, it represents. Proxies can
+/// also be used as spatial place holders or provisions, that maybe
+/// later replaced by special types of elements.
+/// One use of the proxy object is a provision for voids, i.e. where
+/// a particular volume of space is requested by some engineering
+/// function that might later be accepted or rejected and if accepted
+/// potentially transformed into a void within a building element, like
+/// a wall opening, or a slab opening. The provision for voids is
+/// exchanged as an IfcBuildingElementProxy with the
+/// PredefinedType = ProvisionForVoid.
+/// Other usages of IfcBuildingElementProxy include:
+/// 
+/// The IfcBuildingElementProxy can be used to exchange
+/// special types of building elements for which the current IFC
+/// Release does not yet provide a semantic definition.
+/// The IfcBuildingElementProxy can also be used to
+/// represent building elements for which the participating
+/// applications can not provide additional semantic
+/// classification.
+/// 
+/// HISTORY  New entity
+/// in IFC Release 2x.
+/// IFC2x4 CHANGE  The attribute
+/// CompositionType has been replaced by PredefinedType,
+/// being a superset of the enumerators.
+/// Type Use Definition
+/// The IfcBuildingElementProxy defines the occuurence of any
+/// building element, common information about the types (or styles) is
+/// handled by IfcBuildingElementProxyType.
+/// The IfcBuildingElementProxyType (if present) may
+/// establish the common type name, usage (or predefined) type, common
+/// material, common set of properties and common shape representations
+/// (using IfcRepresentationMap). The
+/// IfcBuildingElementProxyType is attached using the
+/// IfcRelDefinedByType.RelatingType objectified relationship
+/// and is accessible by the inverse IsTypedBy attribute.
+/// 
+/// NOTE The IfcBuildingElementProxyType can be used
+/// to share common information among many occurrences of the same
+/// proxy without establishing a particular semantic meaning of the
+/// type.
+/// 
+/// If no IfcBuildingElementProxyType is attached (i.e. if
+/// only occurrence information is given) the PredefinedType
+/// should be provided. If set to .USERDEFINED. a user defined value
+/// can be provided by the ObjectType attribute.
+/// Material Use Definition
+/// The material of the IfcBuildingElementProxy is defined by
+/// IfcMaterial and attached by the
+/// IfcRelAssociatesMaterial.RelatingMaterial. It is
+/// accessible by the inverse HasAssociations relationship.
+/// Note It is illegal to assign an
+/// IfcMaterial to an IfcBuildingElementProxy with the
+/// PredefinedType = ProvisionForVoid.
+/// Material information can also be given at the
+/// IfcBuildingElementProxyType, defining the common attribute
+/// data for all occurrences of the same type. It is then
+/// accessible by the inverse IsTypedBy relationship pointing to
+/// IfcBuildingElementProxyType.HasAssociations and via
+/// IfcRelAssociatesMaterial.RelatingMaterial to
+/// IfcMaterial. If both are given, then the material directly
+/// assigned to IfcBuildingElementProxy overrides the material
+/// assigned to IfcBuildingElementProxyType.
+/// Property Set Use Definition:
+/// The property sets relating to the IfcBuildingElementProxy
+/// are defined by the IfcPropertySet and attached by the
+/// IfcRelDefinesByProperties relationship. It is accessible by
+/// the inverse IsDefinedBy relationship. The following property
+/// set definitions specific to the IfcBuildingElementProxy are
+/// part of this IFC release:
+/// 
+/// Pset_BuildingElementProxyCommon: common
+/// property set for all occurrences of building element proxies.
+/// Pset_BuildingElementProxyProvisionForVoid:
+/// specific property set for all occurrences of building element proxy
+/// with the PredefinedType: PROVISIONFORVOID.
+/// 
+/// Property sets can also be given at the
+/// IfcBuildingElementProxyType, defining the common property
+/// data for all occurrences of the same type. It is then
+/// accessible by the inverse IsTypedBy relationship pointing to
+/// IfcBuildingElementProxyType.HasPropertySets. If both are
+/// given, then the properties directly assigned to
+/// IfcBuildingElementProxy overrides the properties assigned to
+/// IfcBuildingElementProxyType.
+/// Containment Use Definition
+/// The IfcBuildingElementProxy, as any subtype of
+/// IfcBuildingElement, may participate in two different
+/// containment relationships. The first (and in most implementation
+/// scenarios mandatory) relationship is the hierachical spatial
+/// containment, the second (optional) relationship is the aggregation
+/// within an element assembly.
+/// 
+/// The IfcBuildingElementProxy is places within the project
+/// spatial hierarchy using the objectified relationship
+/// IfcRelContainedInSpatialStructure, refering to it by its
+/// inverse attribute SELF\IfcElement.ContainedInStructure.
+/// Subtypes of IfcSpatialStructureElement are valid
+/// spatial containers, with IfcBuildingStorey being the default
+/// container.
+/// The IfcBuildingElementProxy may be aggregated into an
+/// element assembly using the objectified relationship
+/// IfcRelAggregates, refering to it by its inverse attribute
+/// SELF\IfcObjectDefinition.Decomposes. Any subtype of
+/// IfcElement can be an element assembly, with
+/// IfcElementAssembly as a special focus subtype. In this case
+/// it should not be additionally contained in the project spatial
+/// hierarchy, i.e. SELF\IfcElement.ContainedInStructure
+/// should be NIL.
+/// 
+/// Geometry Use Definition
+/// The geometric representation of IfcBuildingElementProxy
+/// is given by the IfcProductDefinitionShape, allowing multiple
+/// geometric representations. Included are:
+/// Local Placement
+/// The local placement for any IfcBuildingElementProxy is
+/// defined in its supertype IfcProduct. It is defined by the
+/// IfcLocalPlacement, which defines the local coordinate system
+/// that is referenced by all geometric representations. The local
+/// placement can be given relativly.
+/// 
+/// The PlacementRelTo relationship of
+/// IfcLocalPlacement shall point (if given) to the local
+/// placement of the same IfcSpatialStructureElement, which is
+/// used in the ContainedInStructure inverse attribute, or to a
+/// spatial structure element at a higher level, referenced by
+/// that.
+/// If the relative placement is not used, the absolute placement
+/// is defined within the world coordinate system.
+/// 
+/// Geometric Representation
+/// Currently, the 'FootPrint', 'Body', and 'Box' representations
+/// are supported. The 'Box' representation includes the representation
+/// type 'BoundingBox' and is explained at
+/// IfcBuildingElement.
+/// FootPrint Representation
+/// Any building element proxy may be represented by a geometric
+/// curve set, given by a collection of 2D points and curves. The foot
+/// pring geometric representation of IfcBuildingElementProxy is
+/// defined using the 'FootPrint' representation.
+/// 
+/// RepresentationIdentifier: 'FootPrint'
+/// RepresentationType: 'GeometricCurveSet',
+/// 'Annotation2D'
+/// 
+/// Body Representation
+/// The body representation of IfcBuildingElementProxy can be
+/// represented using the representation types 'GeometricSet',
+/// 'SweptSolid', 'CSG' 'SurfaceModel', 'Brep', and
+/// 'MappedRepresentation'. The representation types 'SurfaceModel',
+/// 'Brep', and 'MappedRepresentation' are explained at
+/// IfcBuildingElement.
+/// GeometricSet Representation Type
+/// Any building element proxy may be represented by a geometric
+/// set, given by a collection of 2D and 3D points, curves, and
+/// surfaces. It represents the body of the proxy object, when no
+/// topological structure is available. The following attribute values
+/// for the IfcShapeRepresentation holding this geometric
+/// representation shall be used:
+/// 
+/// RepresentationIdentifier: 'Body'
+/// RepresentationType: 'GeometricSet'
+/// 
+/// SweptSolid Representation Type
+/// Any building element proxy may be represented by swept solid
+/// geometry (either by extrusion or by revolution). The following
+/// attribute values for the IfcShapeRepresentation holding this
+/// geometric representation shall be used:
+/// 
+/// RepresentationIdentifier: 'Body'
+/// RepresentationType: 'SweptSolid'
+/// 
+/// No further restrictions (e.g., for the profile or extrusion
+/// direction) are defined at this level. A single or multiple swept
+/// area solid(s) can be the Items of the
+/// IfcShapeRepresentation.
+/// CSG Representation Type
+/// Any building element proxy may be represented by a CSG primitive
+/// or CSG tree. The following attribute values for the
+/// IfcShapeRepresentation holding this geometric representation
+/// shall be used:
+/// 
+/// RepresentationIdentifier: 'Body'
+/// RepresentationType: 'CSG'
+/// 
+/// No further restrictions (e.g., for the depths of the CSG tree)
+/// are defined at this level.

+/// The distribution element IfcDistributionControlElement defines occurrence elements of a building automation control system that are used to impart control over elements of a distribution system.
+/// 
+/// This class defines elements of a building automation control system. These are typically used to control distribution system elements to maintain  variables such as temperature, humidity, pressure, flow, power, or lighting levels, through the modulation, staging or sequencing of mechanical or electrical devices. The three general functional categories of control elements are as follows:
+/// 
+/// Impart control over flow control elements (IfcFlowController) in a distribution system such as dampers, valves, or relays, typically through the use of actuation (IfcActuator).
+/// Sensing elements (IfcSensor) that measure changes in the controlled variable such as temperature, humidity, pressure, or flow.
+/// Controllers (IfcController) typically classified according to the control action they seek to perform and generally responsible for making decisions about the elements under control.
+/// 
+/// Since this class and its subtypes typically relate to many different distribution flow elements (IfcDistributionFlowElement), the objectified relationship IfcRelFlowControlElements has been provided to relate control and flow elements as required.
+/// 
+/// IFC2x4 CHANGE: ControlElementId attribute deleted; replaced by classification usage.
+/// HISTORY: New entity in IFC R2.0.
+/// 
+/// Type Use Definition
+/// IfcDistributionControlElement defines the occurrence of any distribution control element; common information about distribution control element types is handled by IfcDistributionControlElementType.  The IfcDistributionControlElementType (if present) may establish the common type name, usage (predefined type), properties, materials, ports, composition, assignments, and representations.  The IfcDistributionControlElementType is attached using the IfcRelDefinesByType objectified relationship and is accessible by the IsTypedBy inverse attribute.  If the IfcDistributionControlElementType has ports or aggregated elements, such objects are reflected at the IfcDistributionControlElement occurrence using the IfcRelDefinesByObject relationship.  Direct instantiation of IfcDistributionControlElement with IfcObject.ObjectType asserted provides the meaning of a distribution control element proxy.

+/// 
+/// Classification Use Definition
+/// In addition to general product and project classification (UniFormat, etc.), classifications may also be applied to indicate a device address or addressing scheme using IfcRelAssociatesClassification where RelatedObjects contains the  IfcDistributionControlElement and RelatingClassification refers to an IfcClassification or IfcClassificationReference.
+/// 
+/// IfcClassification: Indicates an addressing scheme managed by the device where ReferenceTokens defines the format of the address to be specified at IfcClassificationReference.ItemReference.  A classification hierarchy may optionally be provided indicating detected or provisioned device addresses.
+/// IfcClassificationReference: Indicates the address of the control element where Identification uniquely identifies the element within the control system as determined by the ClassificationSource.  Several examples are illustrated:
+/// 
+/// 'BACnet': BACnetObjectIdentifier in the decimal form '12.15' (Digital Input #15) indicating type ID and instance ID.
+/// 'IP': IP Address in the decimal form '192.168.1.2' such as for an IPv4 network.
+/// 'OPC': Hierarchical ItemID in the alphanumeric form 'B204.Tank2.Temperature'
+/// 'X-10': Alphabetic and numeric code in the form 'B12' (House B, Device 12) indicating House Code and Device Code.
+/// 
+/// Figure 147 illustrates classification usage.
+/// 
+/// Figure 147 — Distribution control classification
+/// 
+/// Composition Use Definition
+/// The IfcDistributionControlElement may be decomposed into components using IfcRelAggregates where RelatingObject refers to the enclosing IfcDistributionControlElement and RelatedObjects contains one or more components.  Likewise, a control element may be aggregated within another element.  For example, a thermostat may contain temperature sensors, and a programmable logic controller may contain virtual (software-based) control elements.  Standard types for composition are defined at subtypes.
+/// 
+/// Connection Use Definition
+/// The IfcDistributionControlElement may be connected to other objects as follows using the indicated relationship:
+/// 
+/// IfcSpatialStructureElement (IfcRelContainedInSpatialStructure) : Indicates the spatial location containing the element.  If an element is aggregated within another element, then only the top-level element participates in this relationship.
+/// IfcElement (IfcRelConnectsElements) : Indicates physical connectivity with another element (but not embedding or flow control), such as a sensor attached to a wall.  IfcRelConnectsElements.RelatingElement refers to the anchored side (for example, wall hosting sensor).
+/// IfcDistributionPort (IfcRelConnectsPortToElement) : Indicates ports on the element which may be connected to other elements for control signal transmission or electric power.  Standard port names, types, and directions are defined at subtypes.
+/// IfcDistributionFlowElement (IfcRelFlowControlElements) : Indicates a flow element is sensed or controlled by the control element, such as a tank for a level sensor or a valve for an actuator.
+/// 
+/// Assignment Use Definition
+/// The IfcDistributionControlElement may be assigned to the following entities using relationships as indicated:
+/// 
+/// IfcDistributionSystem (IfcRelAssignsToGroup): Indicates a system containing interconnected devices, where control elements are typically part of a control system having PredefinedType=CONTROL.
+/// IfcPerformanceHistory (IfcRelAssignsToControl): Indicates realtime or historical infomation captured for the device.
+/// 
+/// The IfcDistributionControlElement may have assignments of its own using the IfcRelAssignsToProduct relationship where RelatingProduct refers to the IfcDistributionControlElement and RelatedObjects contains one or more objects of the following types: 
+/// 
+/// IfcTask: Indicates tasks used to purchase, install, renovate, demolish, operate, or otherwise act upon the element.  If the element has a type, available task types are assigned to the element type.
+/// IfcProcedure: Indicates procedures used to operate the element.  If the element has a type, available procedure types are assigned to the element type.
+/// IfcEvent: Indicates events raised by the element, sequenced by procedures to be followed.  If the element has a type, available event types are assigned to the element type.
+/// 
+/// Material Use Definition
+/// The material of the IfcDistributionControlElement is defined using one of the following entities:
+/// 
+/// IfcMaterialConstituentSet: For elements containing multiple materials, this indicates materials at named aspects.
+/// 
+/// IfcMaterial: For elements comprised of a single material, this indicates the material.
+/// 
+/// The material is attached by the RelatingMaterial attribute on the IfcRelAssociatesMaterial relationship.  It is accessible by the HasAssociations inverse attribute.  Material information can also be given at the IfcDistributionControlElementType, defining the common attribute data for all occurrences of the same type.  Standard names and material types are defined at subtypes.
+/// 
+/// Representation Use Definition
+/// The following shape representations are supported for subtypes of IfcDistributionControlElement, distinguished by IfcShapeRepresentation.RepresentationIdentifier:
+/// 
+/// 'Footprint': Represents the 2D footprint outline of the item having IfcShapeRepresentation.RepresentationType of 'GeometricCurveSet' and containing a single IfcGeometricCurveSet consisting of one or more IfcCurve subtypes such as IfcPolyline, IfcTrimmedCurve, IfcCompositeCurve, or IfcCircle.
+/// 
+/// 'Body': Represents the 3D shape of the item having IfcShapeRepresentation.RepresentationType of 'SurfaceModel', 'SolidModel', or any solid model specializations including 'Brep', 'AdvancedBrep', 'SweptSolid', 'AdvancedSweptSolid', 'CSG', 'Clipping', or 'SectionedSpine').
+/// 
+/// 'Clearance': Represents the 3D clearance volume of the item having RepresentationType of 'Surface3D'.  Such clearance region indicates space that should not intersect with the 'Body' representation of other elements, though may intersect with the 'Clearance' representation of other elements.  The particular use of clearance space may be for safety, maintenance, or other purpose.
+/// 
+/// For all representations, if a IfcDistributionControlElement occurrence is defined by a IfcDistributionControlElementType having a representation of the same identifier, then 'MappedRepresentation' should be used at the occurrence unless overridden.
+/// 
+/// If materials are defined, geometry of each representation (most typically the 'Body' representation) may be organized into shape aspects where styles may be derived by correlating IfcShapeAspect.Name to a corresponding material (IfcMaterialConstituent.Name).

+                    GNU GENERAL PUBLIC LICENSE
+                       Version 3, 29 June 2007
+
+ Copyright (C) 2007 Free Software Foundation, Inc. <https://fsf.org/>
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+                            Preamble
+
+  The GNU General Public License is a free, copyleft license for
+software and other kinds of works.
+
+  The licenses for most software and other practical works are designed
+to take away your freedom to share and change the works.  By contrast,
+the GNU General Public License is intended to guarantee your freedom to
+share and change all versions of a program--to make sure it remains free
+software for all its users.  We, the Free Software Foundation, use the
+GNU General Public License for most of our software; it applies also to
+any other work released this way by its authors.  You can apply it to
+your programs, too.
+
+  When we speak of free software, we are referring to freedom, not
+price.  Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+them if you wish), that you receive source code or can get it if you
+want it, that you can change the software or use pieces of it in new
+free programs, and that you know you can do these things.
+
+  To protect your rights, we need to prevent others from denying you
+these rights or asking you to surrender the rights.  Therefore, you have
+certain responsibilities if you distribute copies of the software, or if
+you modify it: responsibilities to respect the freedom of others.
+
+  For example, if you distribute copies of such a program, whether
+gratis or for a fee, you must pass on to the recipients the same
+freedoms that you received.  You must make sure that they, too, receive
+or can get the source code.  And you must show them these terms so they
+know their rights.
+
+  Developers that use the GNU GPL protect your rights with two steps:
+(1) assert copyright on the software, and (2) offer you this License
+giving you legal permission to copy, distribute and/or modify it.
+
+  For the developers' and authors' protection, the GPL clearly explains
+that there is no warranty for this free software.  For both users' and
+authors' sake, the GPL requires that modified versions be marked as
+changed, so that their problems will not be attributed erroneously to
+authors of previous versions.
+
+  Some devices are designed to deny users access to install or run
+modified versions of the software inside them, although the manufacturer
+can do so.  This is fundamentally incompatible with the aim of
+protecting users' freedom to change the software.  The systematic
+pattern of such abuse occurs in the area of products for individuals to
+use, which is precisely where it is most unacceptable.  Therefore, we
+have designed this version of the GPL to prohibit the practice for those
+products.  If such problems arise substantially in other domains, we
+stand ready to extend this provision to those domains in future versions
+of the GPL, as needed to protect the freedom of users.
+
+  Finally, every program is threatened constantly by software patents.
+States should not allow patents to restrict development and use of
+software on general-purpose computers, but in those that do, we wish to
+avoid the special danger that patents applied to a free program could
+make it effectively proprietary.  To prevent this, the GPL assures that
+patents cannot be used to render the program non-free.
+
+  The precise terms and conditions for copying, distribution and
+modification follow.
+
+                       TERMS AND CONDITIONS
+
+  0. Definitions.
+
+  "This License" refers to version 3 of the GNU General Public License.
+
+  "Copyright" also means copyright-like laws that apply to other kinds of
+works, such as semiconductor masks.
+
+  "The Program" refers to any copyrightable work licensed under this
+License.  Each licensee is addressed as "you".  "Licensees" and
+"recipients" may be individuals or organizations.
+
+  To "modify" a work means to copy from or adapt all or part of the work
+in a fashion requiring copyright permission, other than the making of an
+exact copy.  The resulting work is called a "modified version" of the
+earlier work or a work "based on" the earlier work.
+
+  A "covered work" means either the unmodified Program or a work based
+on the Program.
+
+  To "propagate" a work means to do anything with it that, without
+permission, would make you directly or secondarily liable for
+infringement under applicable copyright law, except executing it on a
+computer or modifying a private copy.  Propagation includes copying,
+distribution (with or without modification), making available to the
+public, and in some countries other activities as well.
+
+  To "convey" a work means any kind of propagation that enables other
+parties to make or receive copies.  Mere interaction with a user through
+a computer network, with no transfer of a copy, is not conveying.
+
+  An interactive user interface displays "Appropriate Legal Notices"
+to the extent that it includes a convenient and prominently visible
+feature that (1) displays an appropriate copyright notice, and (2)
+tells the user that there is no warranty for the work (except to the
+extent that warranties are provided), that licensees may convey the
+work under this License, and how to view a copy of this License.  If
+the interface presents a list of user commands or options, such as a
+menu, a prominent item in the list meets this criterion.
+
+  1. Source Code.
+
+  The "source code" for a work means the preferred form of the work
+for making modifications to it.  "Object code" means any non-source
+form of a work.
+
+  A "Standard Interface" means an interface that either is an official
+standard defined by a recognized standards body, or, in the case of
+interfaces specified for a particular programming language, one that
+is widely used among developers working in that language.
+
+  The "System Libraries" of an executable work include anything, other
+than the work as a whole, that (a) is included in the normal form of
+packaging a Major Component, but which is not part of that Major
+Component, and (b) serves only to enable use of the work with that
+Major Component, or to implement a Standard Interface for which an
+implementation is available to the public in source code form.  A
+"Major Component", in this context, means a major essential component
+(kernel, window system, and so on) of the specific operating system
+(if any) on which the executable work runs, or a compiler used to
+produce the work, or an object code interpreter used to run it.
+
+  The "Corresponding Source" for a work in object code form means all
+the source code needed to generate, install, and (for an executable
+work) run the object code and to modify the work, including scripts to
+control those activities.  However, it does not include the work's
+System Libraries, or general-purpose tools or generally available free
+programs which are used unmodified in performing those activities but
+which are not part of the work.  For example, Corresponding Source
+includes interface definition files associated with source files for
+the work, and the source code for shared libraries and dynamically
+linked subprograms that the work is specifically designed to require,
+such as by intimate data communication or control flow between those
+subprograms and other parts of the work.
+
+  The Corresponding Source need not include anything that users
+can regenerate automatically from other parts of the Corresponding
+Source.
+
+  The Corresponding Source for a work in source code form is that
+same work.
+
+  2. Basic Permissions.
+
+  All rights granted under this License are granted for the term of
+copyright on the Program, and are irrevocable provided the stated
+conditions are met.  This License explicitly affirms your unlimited
+permission to run the unmodified Program.  The output from running a
+covered work is covered by this License only if the output, given its
+content, constitutes a covered work.  This License acknowledges your
+rights of fair use or other equivalent, as provided by copyright law.
+
+  You may make, run and propagate covered works that you do not
+convey, without conditions so long as your license otherwise remains
+in force.  You may convey covered works to others for the sole purpose
+of having them make modifications exclusively for you, or provide you
+with facilities for running those works, provided that you comply with
+the terms of this License in conveying all material for which you do
+not control copyright.  Those thus making or running the covered works
+for you must do so exclusively on your behalf, under your direction
+and control, on terms that prohibit them from making any copies of
+your copyrighted material outside their relationship with you.
+
+  Conveying under any other circumstances is permitted solely under
+the conditions stated below.  Sublicensing is not allowed; section 10
+makes it unnecessary.
+
+  3. Protecting Users' Legal Rights From Anti-Circumvention Law.
+
+  No covered work shall be deemed part of an effective technological
+measure under any applicable law fulfilling obligations under article
+11 of the WIPO copyright treaty adopted on 20 December 1996, or
+similar laws prohibiting or restricting circumvention of such
+measures.
+
+  When you convey a covered work, you waive any legal power to forbid
+circumvention of technological measures to the extent such circumvention
+is effected by exercising rights under this License with respect to
+the covered work, and you disclaim any intention to limit operation or
+modification of the work as a means of enforcing, against the work's
+users, your or third parties' legal rights to forbid circumvention of
+technological measures.
+
+  4. Conveying Verbatim Copies.
+
+  You may convey verbatim copies of the Program's source code as you
+receive it, in any medium, provided that you conspicuously and
+appropriately publish on each copy an appropriate copyright notice;
+keep intact all notices stating that this License and any
+non-permissive terms added in accord with section 7 apply to the code;
+keep intact all notices of the absence of any warranty; and give all
+recipients a copy of this License along with the Program.
+
+  You may charge any price or no price for each copy that you convey,
+and you may offer support or warranty protection for a fee.
+
+  5. Conveying Modified Source Versions.
+
+  You may convey a work based on the Program, or the modifications to
+produce it from the Program, in the form of source code under the
+terms of section 4, provided that you also meet all of these conditions:
+
+    a) The work must carry prominent notices stating that you modified
+    it, and giving a relevant date.
+
+    b) The work must carry prominent notices stating that it is
+    released under this License and any conditions added under section
+    7.  This requirement modifies the requirement in section 4 to
+    "keep intact all notices".
+
+    c) You must license the entire work, as a whole, under this
+    License to anyone who comes into possession of a copy.  This
+    License will therefore apply, along with any applicable section 7
+    additional terms, to the whole of the work, and all its parts,
+    regardless of how they are packaged.  This License gives no
+    permission to license the work in any other way, but it does not
+    invalidate such permission if you have separately received it.
+
+    d) If the work has interactive user interfaces, each must display
+    Appropriate Legal Notices; however, if the Program has interactive
+    interfaces that do not display Appropriate Legal Notices, your
+    work need not make them do so.
+
+  A compilation of a covered work with other separate and independent
+works, which are not by their nature extensions of the covered work,
+and which are not combined with it such as to form a larger program,
+in or on a volume of a storage or distribution medium, is called an
+"aggregate" if the compilation and its resulting copyright are not
+used to limit the access or legal rights of the compilation's users
+beyond what the individual works permit.  Inclusion of a covered work
+in an aggregate does not cause this License to apply to the other
+parts of the aggregate.
+
+  6. Conveying Non-Source Forms.
+
+  You may convey a covered work in object code form under the terms
+of sections 4 and 5, provided that you also convey the
+machine-readable Corresponding Source under the terms of this License,
+in one of these ways:
+
+    a) Convey the object code in, or embodied in, a physical product
+    (including a physical distribution medium), accompanied by the
+    Corresponding Source fixed on a durable physical medium
+    customarily used for software interchange.
+
+    b) Convey the object code in, or embodied in, a physical product
+    (including a physical distribution medium), accompanied by a
+    written offer, valid for at least three years and valid for as
+    long as you offer spare parts or customer support for that product
+    model, to give anyone who possesses the object code either (1) a
+    copy of the Corresponding Source for all the software in the
+    product that is covered by this License, on a durable physical
+    medium customarily used for software interchange, for a price no
+    more than your reasonable cost of physically performing this
+    conveying of source, or (2) access to copy the
+    Corresponding Source from a network server at no charge.
+
+    c) Convey individual copies of the object code with a copy of the
+    written offer to provide the Corresponding Source.  This
+    alternative is allowed only occasionally and noncommercially, and
+    only if you received the object code with such an offer, in accord
+    with subsection 6b.
+
+    d) Convey the object code by offering access from a designated
+    place (gratis or for a charge), and offer equivalent access to the
+    Corresponding Source in the same way through the same place at no
+    further charge.  You need not require recipients to copy the
+    Corresponding Source along with the object code.  If the place to
+    copy the object code is a network server, the Corresponding Source
+    may be on a different server (operated by you or a third party)
+    that supports equivalent copying facilities, provided you maintain
+    clear directions next to the object code saying where to find the
+    Corresponding Source.  Regardless of what server hosts the
+    Corresponding Source, you remain obligated to ensure that it is
+    available for as long as needed to satisfy these requirements.
+
+    e) Convey the object code using peer-to-peer transmission, provided
+    you inform other peers where the object code and Corresponding
+    Source of the work are being offered to the general public at no
+    charge under subsection 6d.
+
+  A separable portion of the object code, whose source code is excluded
+from the Corresponding Source as a System Library, need not be
+included in conveying the object code work.
+
+  A "User Product" is either (1) a "consumer product", which means any
+tangible personal property which is normally used for personal, family,
+or household purposes, or (2) anything designed or sold for incorporation
+into a dwelling.  In determining whether a product is a consumer product,
+doubtful cases shall be resolved in favor of coverage.  For a particular
+product received by a particular user, "normally used" refers to a
+typical or common use of that class of product, regardless of the status
+of the particular user or of the way in which the particular user
+actually uses, or expects or is expected to use, the product.  A product
+is a consumer product regardless of whether the product has substantial
+commercial, industrial or non-consumer uses, unless such uses represent
+the only significant mode of use of the product.
+
+  "Installation Information" for a User Product means any methods,
+procedures, authorization keys, or other information required to install
+and execute modified versions of a covered work in that User Product from
+a modified version of its Corresponding Source.  The information must
+suffice to ensure that the continued functioning of the modified object
+code is in no case prevented or interfered with solely because
+modification has been made.
+
+  If you convey an object code work under this section in, or with, or
+specifically for use in, a User Product, and the conveying occurs as
+part of a transaction in which the right of possession and use of the
+User Product is transferred to the recipient in perpetuity or for a
+fixed term (regardless of how the transaction is characterized), the
+Corresponding Source conveyed under this section must be accompanied
+by the Installation Information.  But this requirement does not apply
+if neither you nor any third party retains the ability to install
+modified object code on the User Product (for example, the work has
+been installed in ROM).
+
+  The requirement to provide Installation Information does not include a
+requirement to continue to provide support service, warranty, or updates
+for a work that has been modified or installed by the recipient, or for
+the User Product in which it has been modified or installed.  Access to a
+network may be denied when the modification itself materially and
+adversely affects the operation of the network or violates the rules and
+protocols for communication across the network.
+
+  Corresponding Source conveyed, and Installation Information provided,
+in accord with this section must be in a format that is publicly
+documented (and with an implementation available to the public in
+source code form), and must require no special password or key for
+unpacking, reading or copying.
+
+  7. Additional Terms.
+
+  "Additional permissions" are terms that supplement the terms of this
+License by making exceptions from one or more of its conditions.
+Additional permissions that are applicable to the entire Program shall
+be treated as though they were included in this License, to the extent
+that they are valid under applicable law.  If additional permissions
+apply only to part of the Program, that part may be used separately
+under those permissions, but the entire Program remains governed by
+this License without regard to the additional permissions.
+
+  When you convey a copy of a covered work, you may at your option
+remove any additional permissions from that copy, or from any part of
+it.  (Additional permissions may be written to require their own
+removal in certain cases when you modify the work.)  You may place
+additional permissions on material, added by you to a covered work,
+for which you have or can give appropriate copyright permission.
+
+  Notwithstanding any other provision of this License, for material you
+add to a covered work, you may (if authorized by the copyright holders of
+that material) supplement the terms of this License with terms:
+
+    a) Disclaiming warranty or limiting liability differently from the
+    terms of sections 15 and 16 of this License; or
+
+    b) Requiring preservation of specified reasonable legal notices or
+    author attributions in that material or in the Appropriate Legal
+    Notices displayed by works containing it; or
+
+    c) Prohibiting misrepresentation of the origin of that material, or
+    requiring that modified versions of such material be marked in
+    reasonable ways as different from the original version; or
+
+    d) Limiting the use for publicity purposes of names of licensors or
+    authors of the material; or
+
+    e) Declining to grant rights under trademark law for use of some
+    trade names, trademarks, or service marks; or
+
+    f) Requiring indemnification of licensors and authors of that
+    material by anyone who conveys the material (or modified versions of
+    it) with contractual assumptions of liability to the recipient, for
+    any liability that these contractual assumptions directly impose on
+    those licensors and authors.
+
+  All other non-permissive additional terms are considered "further
+restrictions" within the meaning of section 10.  If the Program as you
+received it, or any part of it, contains a notice stating that it is
+governed by this License along with a term that is a further
+restriction, you may remove that term.  If a license document contains
+a further restriction but permits relicensing or conveying under this
+License, you may add to a covered work material governed by the terms
+of that license document, provided that the further restriction does
+not survive such relicensing or conveying.
+
+  If you add terms to a covered work in accord with this section, you
+must place, in the relevant source files, a statement of the
+additional terms that apply to those files, or a notice indicating
+where to find the applicable terms.
+
+  Additional terms, permissive or non-permissive, may be stated in the
+form of a separately written license, or stated as exceptions;
+the above requirements apply either way.
+
+  8. Termination.
+
+  You may not propagate or modify a covered work except as expressly
+provided under this License.  Any attempt otherwise to propagate or
+modify it is void, and will automatically terminate your rights under
+this License (including any patent licenses granted under the third
+paragraph of section 11).
+
+  However, if you cease all violation of this License, then your
+license from a particular copyright holder is reinstated (a)
+provisionally, unless and until the copyright holder explicitly and
+finally terminates your license, and (b) permanently, if the copyright
+holder fails to notify you of the violation by some reasonable means
+prior to 60 days after the cessation.
+
+  Moreover, your license from a particular copyright holder is
+reinstated permanently if the copyright holder notifies you of the
+violation by some reasonable means, this is the first time you have
+received notice of violation of this License (for any work) from that
+copyright holder, and you cure the violation prior to 30 days after
+your receipt of the notice.
+
+  Termination of your rights under this section does not terminate the
+licenses of parties who have received copies or rights from you under
+this License.  If your rights have been terminated and not permanently
+reinstated, you do not qualify to receive new licenses for the same
+material under section 10.
+
+  9. Acceptance Not Required for Having Copies.
+
+  You are not required to accept this License in order to receive or
+run a copy of the Program.  Ancillary propagation of a covered work
+occurring solely as a consequence of using peer-to-peer transmission
+to receive a copy likewise does not require acceptance.  However,
+nothing other than this License grants you permission to propagate or
+modify any covered work.  These actions infringe copyright if you do
+not accept this License.  Therefore, by modifying or propagating a
+covered work, you indicate your acceptance of this License to do so.
+
+  10. Automatic Licensing of Downstream Recipients.
+
+  Each time you convey a covered work, the recipient automatically
+receives a license from the original licensors, to run, modify and
+propagate that work, subject to this License.  You are not responsible
+for enforcing compliance by third parties with this License.
+
+  An "entity transaction" is a transaction transferring control of an
+organization, or substantially all assets of one, or subdividing an
+organization, or merging organizations.  If propagation of a covered
+work results from an entity transaction, each party to that
+transaction who receives a copy of the work also receives whatever
+licenses to the work the party's predecessor in interest had or could
+give under the previous paragraph, plus a right to possession of the
+Corresponding Source of the work from the predecessor in interest, if
+the predecessor has it or can get it with reasonable efforts.
+
+  You may not impose any further restrictions on the exercise of the
+rights granted or affirmed under this License.  For example, you may
+not impose a license fee, royalty, or other charge for exercise of
+rights granted under this License, and you may not initiate litigation
+(including a cross-claim or counterclaim in a lawsuit) alleging that
+any patent claim is infringed by making, using, selling, offering for
+sale, or importing the Program or any portion of it.
+
+  11. Patents.
+
+  A "contributor" is a copyright holder who authorizes use under this
+License of the Program or a work on which the Program is based.  The
+work thus licensed is called the contributor's "contributor version".
+
+  A contributor's "essential patent claims" are all patent claims
+owned or controlled by the contributor, whether already acquired or
+hereafter acquired, that would be infringed by some manner, permitted
+by this License, of making, using, or selling its contributor version,
+but do not include claims that would be infringed only as a
+consequence of further modification of the contributor version.  For
+purposes of this definition, "control" includes the right to grant
+patent sublicenses in a manner consistent with the requirements of
+this License.
+
+  Each contributor grants you a non-exclusive, worldwide, royalty-free
+patent license under the contributor's essential patent claims, to
+make, use, sell, offer for sale, import and otherwise run, modify and
+propagate the contents of its contributor version.
+
+  In the following three paragraphs, a "patent license" is any express
+agreement or commitment, however denominated, not to enforce a patent
+(such as an express permission to practice a patent or covenant not to
+sue for patent infringement).  To "grant" such a patent license to a
+party means to make such an agreement or commitment not to enforce a
+patent against the party.
+
+  If you convey a covered work, knowingly relying on a patent license,
+and the Corresponding Source of the work is not available for anyone
+to copy, free of charge and under the terms of this License, through a
+publicly available network server or other readily accessible means,
+then you must either (1) cause the Corresponding Source to be so
+available, or (2) arrange to deprive yourself of the benefit of the
+patent license for this particular work, or (3) arrange, in a manner
+consistent with the requirements of this License, to extend the patent
+license to downstream recipients.  "Knowingly relying" means you have
+actual knowledge that, but for the patent license, your conveying the
+covered work in a country, or your recipient's use of the covered work
+in a country, would infringe one or more identifiable patents in that
+country that you have reason to believe are valid.
+
+  If, pursuant to or in connection with a single transaction or
+arrangement, you convey, or propagate by procuring conveyance of, a
+covered work, and grant a patent license to some of the parties
+receiving the covered work authorizing them to use, propagate, modify
+or convey a specific copy of the covered work, then the patent license
+you grant is automatically extended to all recipients of the covered
+work and works based on it.
+
+  A patent license is "discriminatory" if it does not include within
+the scope of its coverage, prohibits the exercise of, or is
+conditioned on the non-exercise of one or more of the rights that are
+specifically granted under this License.  You may not convey a covered
+work if you are a party to an arrangement with a third party that is
+in the business of distributing software, under which you make payment
+to the third party based on the extent of your activity of conveying
+the work, and under which the third party grants, to any of the
+parties who would receive the covered work from you, a discriminatory
+patent license (a) in connection with copies of the covered work
+conveyed by you (or copies made from those copies), or (b) primarily
+for and in connection with specific products or compilations that
+contain the covered work, unless you entered into that arrangement,
+or that patent license was granted, prior to 28 March 2007.
+
+  Nothing in this License shall be construed as excluding or limiting
+any implied license or other defenses to infringement that may
+otherwise be available to you under applicable patent law.
+
+  12. No Surrender of Others' Freedom.
+
+  If conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License.  If you cannot convey a
+covered work so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you may
+not convey it at all.  For example, if you agree to terms that obligate you
+to collect a royalty for further conveying from those to whom you convey
+the Program, the only way you could satisfy both those terms and this
+License would be to refrain entirely from conveying the Program.
+
+  13. Use with the GNU Affero General Public License.
+
+  Notwithstanding any other provision of this License, you have
+permission to link or combine any covered work with a work licensed
+under version 3 of the GNU Affero General Public License into a single
+combined work, and to convey the resulting work.  The terms of this
+License will continue to apply to the part which is the covered work,
+but the special requirements of the GNU Affero General Public License,
+section 13, concerning interaction through a network will apply to the
+combination as such.
+
+  14. Revised Versions of this License.
+
+  The Free Software Foundation may publish revised and/or new versions of
+the GNU General Public License from time to time.  Such new versions will
+be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.
+
+  Each version is given a distinguishing version number.  If the
+Program specifies that a certain numbered version of the GNU General
+Public License "or any later version" applies to it, you have the
+option of following the terms and conditions either of that numbered
+version or of any later version published by the Free Software
+Foundation.  If the Program does not specify a version number of the
+GNU General Public License, you may choose any version ever published
+by the Free Software Foundation.
+
+  If the Program specifies that a proxy can decide which future
+versions of the GNU General Public License can be used, that proxy's
+public statement of acceptance of a version permanently authorizes you
+to choose that version for the Program.
+
+  Later license versions may give you additional or different
+permissions.  However, no additional obligations are imposed on any
+author or copyright holder as a result of your choosing to follow a
+later version.
+
+  15. Disclaimer of Warranty.
+
+  THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
+APPLICABLE LAW.  EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
+HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY
+OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
+THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
+PURPOSE.  THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM
+IS WITH YOU.  SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
+ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
+
+  16. Limitation of Liability.
+
+  IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
+THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
+GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE
+USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF
+DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
+PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),
+EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF
+SUCH DAMAGES.
+
+  17. Interpretation of Sections 15 and 16.
+
+  If the disclaimer of warranty and limitation of liability provided
+above cannot be given local legal effect according to their terms,
+reviewing courts shall apply local law that most closely approximates
+an absolute waiver of all civil liability in connection with the
+Program, unless a warranty or assumption of liability accompanies a
+copy of the Program in return for a fee.
+
+                     END OF TERMS AND CONDITIONS

+                   GNU LESSER GENERAL PUBLIC LICENSE
+                       Version 3, 29 June 2007
+
+ Copyright (C) 2007 Free Software Foundation, Inc. <https://fsf.org/>
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+
+  This version of the GNU Lesser General Public License incorporates
+the terms and conditions of version 3 of the GNU General Public
+License, supplemented by the additional permissions listed below.
+
+  0. Additional Definitions.
+
+  As used herein, "this License" refers to version 3 of the GNU Lesser
+General Public License, and the "GNU GPL" refers to version 3 of the GNU
+General Public License.
+
+  "The Library" refers to a covered work governed by this License,
+other than an Application or a Combined Work as defined below.
+
+  An "Application" is any work that makes use of an interface provided
+by the Library, but which is not otherwise based on the Library.
+Defining a subclass of a class defined by the Library is deemed a mode
+of using an interface provided by the Library.
+
+  A "Combined Work" is a work produced by combining or linking an
+Application with the Library.  The particular version of the Library
+with which the Combined Work was made is also called the "Linked
+Version".
+
+  The "Minimal Corresponding Source" for a Combined Work means the
+Corresponding Source for the Combined Work, excluding any source code
+for portions of the Combined Work that, considered in isolation, are
+based on the Application, and not on the Linked Version.
+
+  The "Corresponding Application Code" for a Combined Work means the
+object code and/or source code for the Application, including any data
+and utility programs needed for reproducing the Combined Work from the
+Application, but excluding the System Libraries of the Combined Work.
+
+  1. Exception to Section 3 of the GNU GPL.
+
+  You may convey a covered work under sections 3 and 4 of this License
+without being bound by section 3 of the GNU GPL.
+
+  2. Conveying Modified Versions.
+
+  If you modify a copy of the Library, and, in your modifications, a
+facility refers to a function or data to be supplied by an Application
+that uses the facility (other than as an argument passed when the
+facility is invoked), then you may convey a copy of the modified
+version:
+
+   a) under this License, provided that you make a good faith effort to
+   ensure that, in the event an Application does not supply the
+   function or data, the facility still operates, and performs
+   whatever part of its purpose remains meaningful, or
+
+   b) under the GNU GPL, with none of the additional permissions of
+   this License applicable to that copy.
+
+  3. Object Code Incorporating Material from Library Header Files.
+
+  The object code form of an Application may incorporate material from
+a header file that is part of the Library.  You may convey such object
+code under terms of your choice, provided that, if the incorporated
+material is not limited to numerical parameters, data structure
+layouts and accessors, or small macros, inline functions and templates
+(ten or fewer lines in length), you do both of the following:
+
+   a) Give prominent notice with each copy of the object code that the
+   Library is used in it and that the Library and its use are
+   covered by this License.
+
+   b) Accompany the object code with a copy of the GNU GPL and this license
+   document.
+
+  4. Combined Works.
+
+  You may convey a Combined Work under terms of your choice that,
+taken together, effectively do not restrict modification of the
+portions of the Library contained in the Combined Work and reverse
+engineering for debugging such modifications, if you also do each of
+the following:
+
+   a) Give prominent notice with each copy of the Combined Work that
+   the Library is used in it and that the Library and its use are
+   covered by this License.
+
+   b) Accompany the Combined Work with a copy of the GNU GPL and this license
+   document.
+
+   c) For a Combined Work that displays copyright notices during
+   execution, include the copyright notice for the Library among
+   these notices, as well as a reference directing the user to the
+   copies of the GNU GPL and this license document.
+
+   d) Do one of the following:
+
+       0) Convey the Minimal Corresponding Source under the terms of this
+       License, and the Corresponding Application Code in a form
+       suitable for, and under terms that permit, the user to
+       recombine or relink the Application with a modified version of
+       the Linked Version to produce a modified Combined Work, in the
+       manner specified by section 6 of the GNU GPL for conveying
+       Corresponding Source.
+
+       1) Use a suitable shared library mechanism for linking with the
+       Library.  A suitable mechanism is one that (a) uses at run time
+       a copy of the Library already present on the user's computer
+       system, and (b) will operate properly with a modified version
+       of the Library that is interface-compatible with the Linked
+       Version.
+
+   e) Provide Installation Information, but only if you would otherwise
+   be required to provide such information under section 6 of the
+   GNU GPL, and only to the extent that such information is
+   necessary to install and execute a modified version of the
+   Combined Work produced by recombining or relinking the
+   Application with a modified version of the Linked Version. (If
+   you use option 4d0, the Installation Information must accompany
+   the Minimal Corresponding Source and Corresponding Application
+   Code. If you use option 4d1, you must provide the Installation
+   Information in the manner specified by section 6 of the GNU GPL
+   for conveying Corresponding Source.)
+
+  5. Combined Libraries.
+
+  You may place library facilities that are a work based on the
+Library side by side in a single library together with other library
+facilities that are not Applications and are not covered by this
+License, and convey such a combined library under terms of your
+choice, if you do both of the following:
+
+   a) Accompany the combined library with a copy of the same work based
+   on the Library, uncombined with any other library facilities,
+   conveyed under the terms of this License.
+
+   b) Give prominent notice with the combined library that part of it
+   is a work based on the Library, and explaining where to find the
+   accompanying uncombined form of the same work.
+
+  6. Revised Versions of the GNU Lesser General Public License.
+
+  The Free Software Foundation may publish revised and/or new versions
+of the GNU Lesser General Public License from time to time. Such new
+versions will be similar in spirit to the present version, but may
+differ in detail to address new problems or concerns.
+
+  Each version is given a distinguishing version number. If the
+Library as you received it specifies that a certain numbered version
+of the GNU Lesser General Public License "or any later version"
+applies to it, you have the option of following the terms and
+conditions either of that published version or of any later version
+published by the Free Software Foundation. If the Library as you
+received it does not specify a version number of the GNU Lesser
+General Public License, you may choose any version of the GNU Lesser
+General Public License ever published by the Free Software Foundation.
+
+  If the Library as you received it specifies that a proxy can decide
+whether future versions of the GNU Lesser General Public License shall
+apply, that proxy's public statement of acceptance of any version is
+permanent authorization for you to choose that version for the
+Library.
