Imported ray tracing code. Modified gather and scatter ops to optionally work on a smaller number of elements. Added two gather and scatters ops specifically for the ray tracer.

Working on a basic level.
Working much better. Field of view seems slightly off.
Color map is working. Still a problem on it being set correctly when changing the field.

Made light stay in one place which allows for shadows to be seen. FOV issue resolved.
Setting ambient occlusion max ray length to 1/5 the magnitude of the bbox extent.
Saving before adding occlusion accumulation.
Added support to accumulate ambient occlusion when the camera does not move.

Fixed memory issue.
Switching scalar fields now regenerates geometry.
Now checking to see if any primitives have been leaded into the scene.

Prep for shoving sphere shaped object into triangle shaped BVH. Small cleanup as well.
Increased ray triangle intersection epsilon in order to eliminate artifact with high density rectilinear grids.
Turned AO back on.
A little clean up.
