Update README.md
Add cell proximity/area of influence
Switch to directional lights because shadows are kinda slow
Some Kernel code for stream compaction

uses naive scan
-One scatter for points
-One scatter for tris
Some cells were erroneously considered proximate
Fixed a few typos
Compute bounding boxes, which are used for object centers and can be used as collision bounds
Cross some things off of the todo list
Started integrating gpu stream compaction
Working Stream compaction

Stream compaction is working for triangles, but not integrated into the
actual algorithm loop.
Merge pull request #2 from kainino0x/test5

Merge test5 into master (working stream compaction)
Removed stream compaction code

the gpu stream compaction code now lives on the stream-compaction
branch.
Saving the current readme with checklists and stuff to README_OLD
Tons of timing info
Fix spacing for no real reason
