  // The diagnoser is derived from the basic generator and, hence,
  // provides std access to states, events and transitions
 
  // Declare diagnoser 
  Diagnoser d1, d2;
 
  // Copy name to diagnoser d1
  d1.Name("Diagnoser");
  
  // Insert some states in diagnoser d1
  Idx s1 = d1.InsInitState("s1");

  // Insert some events in diagnoser d1
  Idx eventA = d1.InsEvent("a");

  // d1.ClearFailureTypeMap();
 
  
  // ******************** State estimate attributes of diagnoser objects
 
  // Attatch generator state estimates to the diagnoser states
 
  // Diagnoser state s1 carries the generator state estimate 1N
