The Extensible interface can be implemented when a given class
wants to provide dynamically added fields. Once this is implemented
to return a Map, the FieldValue system will be able to look in
the Map to see if the desired field exists.
One restriction applies for extensible fields -- you must set the value
of the field before attempting to access itr, else an exception will
be thrown.
