Adjusted LAYERS_PER_CONTACT from 3 to 4. This is not a preferred

solution;  it would be much better to make the value adjustible, but
the array of tiles sized to LAYERS_PER_CONTACT is a Region structure,
and the routine that frees the Region structures does not have a way
to call a routine to take additional measures like free'ing a sub-
structure of the Region.  A proper solution will require some work.
