Rewrite BoundingVolumeHierarchy
...
New BVH has much cleaner design and is also using a much better
heuristic for dividing the scene.
Massive speedup (~28x!), presumable from having a heuristic that
actually works. This is still a simple heuristic (sort by
bounding box centres along largest dimension, and then divide into
equal halves) which can definitely be improved.

For simple_scene benchmark, regerenerate BVH periodically
...
This makes the results much more consistent run-to-run. I suspect
the inconsistency was caused by random variations in the memory
layout of the BVH.
