        * PROTOCOL: Changed board cell numbering to start with zero
        instead of one.

        * src/Makefile.am:
        * src/test-board.c: (main): Added new file for testing.

        * src/ttt-board.c: (ttt_board_init), (ttt_board_to_string):
        * src/ttt-board.h: Implemented board_to_string.
