Title: Added AABB support

I added basic support for axis-aligned bounding boxes. I may go slightly further into other simple intersection tests (capsule, sphere, possibly convex hull), but I'm not turning this into a 3D physics package or anything -- you're not going to see bounding volume hierarchies or anything like that. Intersection tests are very useful even for pure graphical applications.
