geometry module
- rename functions from camel case.
- added docs for undocumented methods.
- minor functional changes with exceptions and accepting 3d/4d vectors where it makes no difference.

Renamed:
- geometry.Intersect -> intersect_ray_tri
- geometry.ClosestPointOnLine -> intersect_point_line
- geometry.PointInTriangle2D -> intersect_point_tri_2d
- geometry.PointInQuad2D -> intersect_point_quad_2d
- geometry.LineIntersect -> intersect_line_line
- geometry.LineIntersect2D -> intersect_line_line_2d
- geometry.BezierInterp -> interpolate_bezier
- geometry.TriangleArea -> area_tri
- geometry.QuadNormal, TriangleNormal -> normal
- geometry.PolyFill -> tesselate_polygon
- geometry.BoxPack2D -> box_pack_2d
- geometry.BarycentricTransform -> barycentric_transform
