+/**
+ *	Contains a sphere-vs-tree collider.
+ *	This class performs a collision test between a sphere and an AABB tree. You can use this to do a standard player vs world collision,
+ *	in a Nettle/Telemachos way. It doesn't suffer from all reported bugs in those two classic codes - the "new" one by Paul Nettle is a
+ *	debuggued version I think. Collision response can be driven by reported collision data - it works extremely well for me. In sake of
+ *	efficiency, all meshes (that is, all AABB trees) should of course also be kept in an extra hierarchical structure (octree, whatever).
