[yt-dev] Old halo objects

Hi all, With the new halo analysis machinery that Britton, Brian C and Hilary have been working on getting integrated into mainline, do we still need the old halo objects machinery? It seems to me that if we are able to replicate all the functionality, *and* call the old halo finders, we don't need the actual code for "class Halo" and "class HaloFinder" and the like. This is the stuff that's mostly in halo_objects.py in yt/analysis_modules/halo_finding/ . Britton, Brian and Hilary -- does that sound okay to you? -Matt
