By default, updating will happen left-to-right.

So you want a notion of N items being at a certain grid site, but only
the one on top to run?  If the notion is that the environment is
acting on the agents, e.g. sun shining, then you might want to have
the model iterate over the cells calling a method like `getTop'.  You
could implement that with a stack on each cell (methods like push,
pop, getTop).  Otherwise, you could have the self-scheduled agents
call getTop on the cell (which they would have a field for), and compare
it with themselves (`this'), and if there was a match, do the behavior.
