- Convex polyhedron class.
- Axis aligned bounding box (AABB) class.
- Fixed segment direction normalization.
- Added tetrahedron class.
- More robust traingle and plane/line intersection algorithm.
- Breaking changes: Line.PerpendicuarTo(Line) now returns 'null' for parallel lines.
- Fixed distance from triangle to point calculation.
- Intersection check of triangle with triangle and box.
