Re: 2d dimensional sets

Hi Thomas,

I'm a little vague about what you are doing, but
my first thought is that you may need to derive a
second Data object from your first (possibly in
a CellImpl that liustens for changes in the first
and produces the second). The second would be the
result of some meth that would make the 2nd display
easy.

Good luck,
Bill
