Wrote text client. Still needs major debugging.
Debugging, still not fixed
Fixed Board.get_row_strs, debugging
Finished debugging, everything appears to work.
Added arrows and numbers to gutters to make board selection more intuitive.
Added exit routine, the board is now printed out in a couple more places during gameplay.
Fixed a bug where the board was not recognizing some completed sub-boards as completed and forcing the user to move onto them.
