various tweaking and figuring on the octree. The weird hybrid dfs bfs thing they have going will be annoying to do in one pass. Might defer it out to two passes. First building the octree, second culling and passing the octree to the gpu

MBP was having problems with out of bounds memory operations with the way the cam dir was handled. sf::vector3f -> float3 and while accessign the Zth element. I'm assuming it was because of some weird backend stuff regarding that gentypeOdds are actually gentypeOdds + 1. Converted write_imagef's to write_imageui's though I don't think that really helps anything. Fixed the bottom half of the screen getting cut off. View matrix import error. Fixed problem the MBP had with negative values during device init, that was a weird one.

Large amount done. OpenCL is almost completely abstracted out to the class

Ahh! It works!! The camera is great now, it yaws and pitches perfectly, just need to limit it to 180 -> -180 on the pitch. There is still a problem when viewing in the negative angles, and as you move the camera closer to 0 things get weird and distorted. But the transfer over to a spherical camera point and a cartesian view plane worked fantastically
