Iterating over all the objects in an ObjectGrid2D means iterating over every single
cell in the array.  If you don't have a lot of objects relative to the cells, this can
be very slow, and it would make more sense to use a SparseGrid2D instead.

You could use a double for-loop to go through all the objects.  But elements() isn't too slow, and it's O(1).
