Add displayed information in a cell that has numbers within paranthesis like
"(2,-3)". Here is an example:
-3 -2 -1 0 1 2
3 |
2 |
1 ----(1, -2)
0
-1

There would be "axis" numbers on the edge of a "map". Every cell in the map
would display the location in the map as (row, col), like "(1,-2)" in the
example above. Thanks.
