There's really not much to see here -- Python 3 support is essentially
identical to 2.7 support, except for a few small syntax changes. I've
combined the multiple depthlimitedmfXY.py files back into depthlimitedmf.py
and it's not too too grotty, though there are some bits which need to be
copied. Overall, though, I think it's a win for now.
Brian's been testing this on Python 3 code, and it seems to work as well
(and as poorly) as it does on Python 2 code, so that seems to be enough.
