[Yt-dev] kD-tree for particles onto grids

[Matthew Turk]

Hi Stephen (et al),

I'm interested in taking particle-only data and putting it into a
regular, multi-level grid structure that has yet to be created.  I
think using a kD-tree, where we specify a maximum number of particles
in a given region, could be used to identify regions that should be
covered by grids.  Do you think that your kD-tree code would be
suitable for this?
