Known Subclasses:

This is a base class for dictionary-like interfaces to
databases.

Methods:
get                  Lookup a key in a database, with a default value.
get_as               Lookup a key and convert to an object.
__getitem__          Lookup a key in a database.

    THE FOLLOWING SHOULD BE IMPLEMENTED IN A DERIVED CLASS.
_get                 Return the data indicated by key.
_convert_to          Convert the data to another object.
    IMPLEMENT THESE ONLY IF TIMEOUT OR CONCURRENT ACCESS IS NEEDED.
_make_pickleable     Make the object returned by _get to a pickleable.
_unmake_pickleable   Turn the pickleable object back into the original
