[pooma-dev] Cooperation between FieldStencil and Range?

[Norbert Nemec]

Actually, I would love to forget about the whole "Field" stuff altogether, since
I do not need that whole overhead of geometry information.

Only reason I switched to field instead of array is that I need periodic boundary
conditions and I would really love to use the mechanisms built into field instead
of doing all the copying by hand.

Why is it, that automatic boundary conditions are not part of Array, even though the
concept is completely independant from geometry information?
