 * This is an interface for an editing pane. The idea is that

 * for PDUs--a panel with the fields and layout for ESPDUs,
 * fire pdus, detonation PDUs, etc. This panel has to be 
 * able to accept a PDU for editing, and be able to update a
 * pdu to the new values the user has typed in the fields. 
 * This is what this interface enables--the Panel subclass
 * can accept a PDU, and return an updated PDU object from
 * the fields the user has modified.
