grid2d suggestion

[Paul E Johnson]

I found this handy in a subclass of Grid2d I have been using. Could it
be installed in Grid2d?

If you want something done by each object in a Grid2d:

- passThrough: (SEL) aSelector
{
  int x,y;
  id cell;

  for (x=0;x< xsize; x++)
    for (y=0; y<ysize; y++)
      {
          cell = *discrete2dSiteAt(lattice, offsets, x, y);
        if (cell)
          [cell perform: aSelector];
      }
  return self;
}


For completeness, I suppose I'd also want to be able to pass arguments,
so :

- passThrough: (SEL) aSelector : arg1
{
  int x,y;
  id cell;

  for (x=0;x< xsize; x++)
    for (y=0; y<ysize; y++)
      {
          cell = *discrete2dSiteAt(lattice, offsets, x, y);
        if (cell)
          [cell perform: aSelector with: arg1];
      }
  return self;
}

and so forth.
