Added some basic geometric primitives such as planes, rays, segments and lines (plus some extra functions like xProject, xBarycentric, Lerpf), as well as some intersection tests between them. Additionally, I split massive math test into smaller ones and tweaked unit test library (testing no longer stops after first failure).
