Design and play cross sum games

^o open an existing file
^s save the current board to a file
^r recompute the game for the board
^q quit
p switch to playing mode
v switch to verifying play mode
d switch to designing mode

When in playing mode, you change the numbers by clicking on the square you wish to change. The number for the square is dependent on the position in the square that you click. Verifying play mode is identical to play except erroneous answers are highlighted.

In desiging mode you can change a square from an answer square to a blank square by clicking on it. One click toggles it. When you finished designing, use ^r to compute a puzzle for the board Squares are mirrored, if you want to override this press CTRL while you click

The rules are:

1. Sums must be formed from strings of [1,9] with no dups
2. The grey squares are the answers, numbers above the diagonal are the answers for the sum to the right numbers below the diagonal are the answers for the sum below
