* Made print_board accept a board to print.

* free_board should not return anything.

* is_valid_move and has_valid_moves accept a board.

* Implemented primitives for Scheme strategies to get the current
  player, and to get the board, and the validity of a move.

* Removed game logic from is_valid_move. Instead simply apply the move
  to a temp board, and see if the move worked.

* Created a very simple strategy for testing these primitives. It only
  hardcodes the first move, and then fails since that move is no longer
  valid.
