Something resembling an Octree: 2

My expanding octree implementation is now cleaned up and checked into a random SVN repository.

I thought I might as well flesh it out and get it to a polished state, as there are a few of my projects for which that hasn't been done. My Gmail backup script is one that badly needs a GUI added to it, for instance.

It has always been a mystery to me that people actually used the Gmail backup script, as it just dumps backed-up emails as pickles. As such, anyone who uses it either doesn't care that they don't know how the emails are stored, or they are willing to do the extra work required to work with the dumped files.
