"""
Manages alignment layout (business logical) and alignment geometry (geometric representations).
This API does not determine alignment parameters based on rules, such as minimum curve radius as a function of design speed or sight distance.
This API is under development and subject to code breaking changes in the future.
Presently, this API supports:
1. Creating alignments, both horizontal and vertical, using the PI method. Alignment definition can be read from a CSV file.
2. Adding business logic and geometric segments to the end of an alignment
3. Adding and removing the zero length segment at the end of alignments
4. Creating geometric representations from a business logical definition
5. Mapping individual business logical segments to geometric segments (complete for horizontal, missing clothoid for vertical, not implemented for cant)
6. Using curve geometry to determine IfcCurveSegment.Transition transition code.
7. Utility functions for printing business logical and geometric representations, as well as minimumal geometry evaluations
Future versions of this API will support:
1. Defining alignments using the PI method, including transition spirals
2. Updating horizontal curve definitions by revising transition spiral parameters and circular curve radii
3. Updating vertical curve definitions by revising horizontal length of curves
4. Removing a segment at any location along a curve
5. Adding a segment at any location along a curve
