Accepts grid spacing arguments and a block. Duplicates the block with a transformation for each grid point. If the block has arity==1, then pass it the x-coordinate for each grid point and group the resulting geometry by y-value. If the block has arity==2, then pass it x and y for each grid point and put all of the generated geometry in a single group.
