Every class set up. Board#move implemented
Board changed to be 8x8. Piece can compute correct moves, excepting skip-chains.
#grow_skip_chain works, computing the max length skip chain. Breaks ties by just going left.
Correctly computes moves that come as the result of chain-skipping.
Checkers now functions according to the rule that compels jumps when they're possible
