===Kernel Optimization Attempts===
These Kernels change a minor part of the Optimized Kernel or use a slightly different algorithm in an attempt to make it faster
 
Change : Replaces the boolean array hasSeen with a single int & uses bitwise operators
Theory : Since local array variables of threads are stored in Global memory this was an attempt to move that into the register
Result : No speed up noticed, suggesting that more is happening beyond arrays stored in Global memory, perhaps some type of paging, more testing would be needed on something less erratic then a Sudoku Solver
