I have been following this whole discussion, I think this all looks really good. Hamiltonian has always made no sense to me (maybe vonNeumann vs. Moore? I think Square vs. Diamond is still the most intuitive).

The overhaul of neighborhood functions in the grids gives us an opportunity to do some renaming of the new functions.  Issues:

        - Sometimes we use "Position" (MASON terminology for a point on-screen) when we mean "Location" (MASON terminology for a location in a field), and that should be rectified

        - "Max" and "Hamiltonian" are strange names.  Hamiltonian in particular is a term borrowed, I believe, from Repast, and I can't see any justification for it.  I am inclined to use "Square" and "Diamond", though this means we have to use different terms for the 3D case.

        - "Neighbors" should refer to objects, not locations.

        - It'd be nice if the names were shorter.

So here is a possible renaming.  I'm just throwing it out here to get some feedback.
