Add DAExampleModule to demonstrate dynamic attributes
This module demonstrates that we can add an arbitrary persisted value to SOP without any changes to core code. Every time the object is moved, the move record is updated and the users in the scene alerted The number of moves is persisted over server restarts in sqlite
