Avoid if statements for checking neighboring indexes in a 2D array

[kerdemdemir via Digitalmars-d-learn]

Of course now I will try to have it work first. Than replace for 
loops with Cartesian product calls. Than I will make 2D array 
template and even maybe with random access range. And finally for 
being able to use this class later in the some other coding 
challenge I will make Searching( == 'W' part) and Process 
functions passed by parameter.

Thanks a lot for help.
