xisola: a logic game

[muggins]

this consists of the one file, xisola, which is copied to /usr/bin. type, in a console, xisola to run. it's only a black&white game, with very simple rules, but a bit of strategy. you have to move your piece to an adjacent square, then select a "blocking" square to try & stymie your opponent. the loser is the player unable to move.
