* Some numerical conventions:
|
|
*
|
|
* Arrays have white's value in [0], red in [1].
|
|
* Numeric values which are one color or the other use
|
|
* -1 for white, 1 for red.
|
|
* Hence, white will be negative values, red positive one.
|
|
* This makes a lot of sense since white is going in decending
|
|
* order around the board, and red is ascending.
