[yt-users] pickling clumps

[Britton Smith]

Hi Chris,

YT has its own routine designed to pickle data objects for saving and
reloading.  For a given pf, you can do pf.h.save_object(object, name) and
the object will be saved to the .yt file associated with the dataset.  You
can then get it back with object = pf.h.load_object(name).  I have used this
successfully to save the mast_clump structure from clump finding.
