There are whole papers written about how to do the STL style iterators with 2D 
structures (notably by Ulrich Koethe, see 
http://kogs-www.informatik.uni-hamburg.de/~koethe/vigra), and the solutions 
are never quite satisfactory.

We also seldom use our iterators in the STL way -- i.e, define an algorithm 
that takes an iterator as a parameter. Our way is more to create the 
iterators in the code and use them as an effcient, albeit complicated loop.

So I don't think that we need to keep doing it the STL way, and that we might 
was well do what's most convenient for our purposes: I think your suggestions 
are spot on, and I'm waiting with bated breath and eager anticipation :-).
