rectangular grid of CELLs, but the top of the grid meets the bottom
and the left side meets the right side. A UNIT that moves off the top
of the board will find itself on the bottom, etc. The DIMENSIONS of
the board (number of CELLs in each direction before wraparound) are
specified by two parameters,
