[chimera-dev] Pickle a molecule object?

[Greg Couch]

No, as shown by the traceback, you cannot pickle internal chimera objects. 
This is due to the way chimera makes its C++ objects available as Python 
objects.  We plan to fix it when we change our session saving technology, 
but there is lots of other stuff to do with higher priority.
