[yt-users] Particle profiles

[Matthew Turk]

Yeah ... my face is a bit red.  This solution will almost certainly
work, and if it does it will be much faster.  In Enzo, the
Dark_Matter_Density field (if it's in your output) is a pre-computed
deposited field -- the same thing as particle_density[_pyx], except
without having to compute it on the fly in yt.  Thanks, Christine!  :)
