Stuck on some CG stuff

So we've put the CPU side of this project to rest. We've tested our BVH tree to death CPU side, but things aren't synching up on the cg side. We struggled for a couple of days just getting our cg code to compile. Apparently there's a problem having cg that doesn't know the number of loop iteration in a while loop while compiling. Now that that's sorted out we are working on calculating the ray intersections on the GPU side.
