Clarification:Re: cellular automata and OOP

Sorry, in rereading this, I realize I was not as clear as I might have
wished. I meant to say that although there may ultimately be hundreds of
individual entities on on a lattice site, there would be only 5-6 different
types of entities. Each type may interact with a subset of the remainder.
Each time step would involve identifying potential interactions, choosing
which ones will occur, and updating all involved entities. This would be
followed by updating the internal dynamics and diffusion to adjacent sites
for all.
