Yes, although I have been thinking about rewriting them to be in
Cython, building on the code John ZuHone recently wrote.  This would
mean the grids would be faster, and with pure-C attributes for things
like left/right edges, we could do point location and geometry
selection much faster.  As it is, the selection still does everything
the dumb way: iterating over every left/right edge and looking for
collisions.  Anything like that would be a YTEP of its own, and would
also minimize or avoid completely backwards incompatible changes.
