Cleaned up .toString() WITH NEW BUG is desc.

I made toString() better, however with the squares that have only 9
values (3 x 3) instead of 16 (4 x 4) the row counter counts to 4
instead of 3. I also got rid of the other runner because it isn’t
needed. I planned to do this in study. nice job getting it done. its an
easy fix ill show u in cavBlock.
