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.
