Added multi-hit intersection.
A ray will now return all objects which it intersects with. It's slower then optimal but based on the console output
it appears to be still much faster than without a BVH. More testing is required.
Working on fixing issues with the BVH implementation.
Commiting a working changes version. Code has been cleaned up considerably.
A proper code review is nessacary in the near future.
Currently it appears that the view matrix is rotating the world
and look at pos view matrix is producing incorrect results. appears as if the height is inverted.
