[Yt-svn] yt-commit r537 - trunk/yt/raven

New Revision: 537
URL: http://yt.spacepope.org/changeset/537

Log:
Another couple changes.  Now, while you ''can'' interact with the object, you
can also provide a pre_call:

my_vrc.run(pre_call=lambda a: a.add_isosurfaces(3, amin=0.1, amax=0.15))

for instance.  Or, more complicated things I haven't thought of.
