[yt-dev] Issue #1034: halo callback docstring issue (yt_analysis/yt)

New issue 1034: halo callback docstring issue https://bitbucket.org/yt_analysis/yt/issue/1034/halo-callback-docstring-issu... Nathan Goldbaum: The docstring for the virial_quantities halo callback is incorrect. The docstring references a `critical_density` keyword argument, but the actual function signature contains a `critical_overdensity` keyword argument. While fixing this, it would probably be worth giving the rest of the docstrings in this file a once-over.
