NOTE: Don't get too excited. This doesn't work very well at present (see Issues & TODOs). But feel free to try it, maybe even make it better.
Constructive Solid Geometry (CSG) for Unity in C#
Direct port of https://github.com/timknip/csg.as (Actionscript 3) to C# / Unity.
Nice summary with pseudocode of the algorithm: https://www.andrew.cmu.edu/user/jackiey/resources/CSG/CSG_report.pdf

- Works, but adds a whole pile of verticies that don't need to be there. Find a way to simpify the mesh for tris that share a plane (maybe http://www.melax.com/polychop) ?
- Currently does nothing with the 'shared' field on Polygons. We could use this for tracking submeshes / materials ?
- Almost certainly could do with optimization (eg, some Lists could probably become Vertex or Polygon arrays).
