Having thought over the problem of increasing
special cases and restrictions, I think it justifies
going to OO programming (presumably Java
on Metrowerks) for the next major revision.
As I understand it, OO will make it easier and safer
to constrain activities on particular dimensions
and cell types.
A slight complication is that cell attributes and
anatomies will have a virtuality that maps oddly
to OO, but we'll get to that.
