[Yt-dev] yt fof question

[Britton Smith]

Stephen,

It looks like if I take any random particle in a halo made with yt FOF, it's
in a completely different halo in inline FOF, or not in any halo at all.
Michele is checking this out right now, but it basically looks like the
particle lists for the same halo found with the two different methods are
completely different.
