  3.  
  4.         Class that represents objects that need access to the global
  5.         event record. An EBCollaborator maintains a list of provider
  6.         objects and a list of dependent objects. When an EBCollaborator
  7.         changes, it sends itself the BroadcastChange message. Each
  8.         dependent then receives the ProviderChanged message which packages
  9.         an EventRecord along with it.
  10.         
  11.         If any object handles the event, change the event.what to a nullEvent
  12.         so it is effectively ignored by the application.
