Nothing built-in, really.  You might subclass Grid2d with an extra
objectCollection ivar, along the lines of what Object2dDisplay does.
If you override the -putObject:atX:Y: you can keep the new collection
you make in sync with the lattice, and use the Collection forEach: methods
to do the iteration.
