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

from init to kernel compilation. Next will be getting buffer handling, executing, and reading done.
Changed the kernel to a more minimal example.
Added a jump table for error codes and an assert function for error checking.
Added a routine to compare all the available cl devices and platforms, chooses the high clock of either the GPU or CPU.
