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

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? -Matt
