(Chiming in from the great beyond)

Britton makes a good suggestion, but I think that people should be
aware of two things:

- cKDTree will be much faster than KDTree. The latter is pure-python
- Looking at the source below, it looks like I never added periodicity
to KDTree operations

It wouldn't be difficult to add periodicity to KDTree, but I just didn't do it.
