[Yt-dev] Column Density derived field

[Stephen Skory]

Matt,

with regards to your comments on how to complete/fix the
AdaptiveRaySource stuff, I think that my interest in trying that would
be driven both by my possible need for something faster and with, as
you said, refactoring of the volume rendering stuff. If I need
something faster remains to be seen.
