It was a bit confusing UX since when you finish editing arbitrary profile path the data is already saved in ifc but you were still in editing profile properties
IfcRelConnectsElements type of connection wasn't handled properly resulting in errors.
Now you should be able to see connections for connected slabs, walls etc - https://i.imgur.com/LpFBKBC.png

While these actions are short in the backend--taking about 0.01 seconds to run--the Blender UI lags a lot leading to 2-3 second pauses because of the "refresh_brick_viewer" function being slow. This should be investigated.
- Turns out, you need the keyword "graph=" in graph_at() to actually select a graph of that name from the collection, otherwise it just returns the entire collection, so I changed that, which correctly isolates the project from the collection for serialization now.
- With this same change, I opted turn BrickStore.VersionedGraphCollection simply into BrickStore.graph and create a new BrickStore.get_project() to return the isolated graph. - This meant I should remove the reload_graph() function because I was actually just loading the entire collection into it still, and its functionality breaks when it isn't the entire collection
All the right code seems to be in place, but it seems the package won't go through with the serialize function because of read/write permissions (ERRNO 13)
I wanted to just have a BrickStore.clear() which would so this:
BrickStore.VersionedGraphCollection = None
BrickStore.graph = None
BrickStore.path = None
(aka not also set BrickStore.schema = None, since it should theoretically just load in the same path anyway) but for some reason Blender crashes when clearing a project and loading one again this way.
- Reworked `load_brick_file` and `new_brick_file` to fit under the VersionedGraphCollection implementation. (Other methods may have broken).
- Added `undo_brick` and `redo_brick`.
- Kept BrickStore.graph the same as to generally still work with the rest of the code. This was done by parsing the VersionedGraphCollection with the new `reload_brick_graph` method.
it was assuming it's a slab and was giving errors trying to start editing slab profile

if extrusion.Position:
AttributeError: 'NoneType' object has no attribute 'Position'
now we're going to store all texture paths in .ifc as posix to keep them working if .ifc moved from one platform to another
previously it was saving all paths as absolute
