What I am looking for is:

* A generalization of range to multi-dim (starting with, at minimum, 2d)

* What makes range useful?  The ability to generically traverse containers,
accessing (ro/rw) the elements.

The example I gave has an interface that looks like vector<vector>>, but
that is a result of thinking about how I would like a generalization of
range traversal to look.

I didn't state it, but I imagine the 2d range would also support traversal
by columns, and maybe other types of traversal.  The row/col example was
just an example (but a common one).

Of course, not all 2d ranges would support all kinds of traversal.
