[yt-users] Halo finding on user-given variables

[Michael Zingale]

Curious about this too, I just tried the clump finder -- churns for a while
but then crashes because it cannot find a jeans_mass field, so it seems
that it is atleast still thinking about gravitational clumps and not
general topologically-connected blobs of a random variable.  I'll poke
around some on this.
