Comment (by nbruin):
Replying to [comment:6 tscrim]:
> Like integer matrices, these are certain combinatorial objects and
"integer" is really "non-negative integer" and usually there are other
constraints like max entry or a fixed sum. From a quick look-over, it
doesn't look like there's anything that is that general purpose (although
perhaps generalizes stuff from `IntegerMatrices`).
OK, so that sounds like it should be a wrapper to provide combinatorial
methods and interfacing with parent and category infrastructure (if it's
worth the overhead). The underlying datastructure should probably be a
numpy.array, though, rather than a tuple of integer arrays. Numpy offers a
lot of functionality to overcome the row-major (or column-major) problems
one usually encounters.
