Fixed brute State references in sudoku
Fixed size and iter references in test
Added size arguments to BitBoard instances in test
Removed pass from test
Removed SEEDCOUNT from sudoku, in preparation for recursive brute solution
Removed recording of seeds from sudoku; the final seeds can be derived from the prompt of the solved game and the base game.  A TODO was added to this effect
Added seedCount argument to Sudoku.copy().  I doubt it will ever be used, though.
Removed printSeeds from final print
Changed printSeeds to printSeed since only one seed will be printed at a time
Added TODO
