Object Persistence

MORTICIA would benefit from a robust yet simple object persistence scheme.

There are potential issues with using pickle in development. From https://wiki.python.org/moin/UsingPickle: Pickles can cause problems if you save a pickle, then update your code and read the pickle in. Attribute added to your init may not be present in the unpickled object; also, if pickle can't find your class and module (e.g., if you renamed the module) you will get errors. For this reason, you should be wary of using pickles for long-term storage where the underlying code is not highly stable.
