btContinuousDynamicsWorld adds optional (per object) continuous collision detection for fast moving objects to the btDiscreteDynamicsWorld. This copes with fast moving objects that otherwise would tunnel/miss collisions. Under construction, don't use yet! Please use btDiscreteDynamicsWorld instead.

these should be 'temporal' aabbs!
'toi' is the global smallest time of impact. However, we just calculate the time of impact for each object individually. so we handle the case moving versus static properly, and we cheat for moving versus moving
calculate time of impact for overlapping pairs
