/**
   This behaviour serves the actions of the FIPA management ontology 
   supported by the AMS.
   Extends RequestManagementBehaviour and implements performAction() to 
   i) call the method of the AMS corresponding to the requested 
   action and ii) prepare the result notification depending on 
   whether a result should be returned (RESULT or DONE).
   Note that all actions in the FIPAManagementOntology produce a 
   "synchronous" effect --> there is no need to delay the notification 
   at a later time as for some actions in the JADEManagementOntology.
