ITopicDefnProvider

All topic definition providers must follow this protocol. They must at very least provide a getDefn() method that returns a pair (string, ArgSpecGiven), or (None, None). The first member is a description for topic, and second one contains the listener callback protocol. See note in MasterTopicDefnProvider about what it returns based on the return of getDefn().
