//  The G4VFastSimulationModel objects are attached to the envelope
// through a G4FastSimulationManager.
//   This object will manage the list of models and will message them
// at tracking time.

  // Constructor/Destructor
  //------------------------
  // Only one Constructor. By default the envelope can
  // be placed n-Times. 
  // If the user is sure that it is placed just one time,
  // the IsUnique flag should be set TRUE to avoid the
  // G4AffineTransform re-calculations each time we reach
  // the envelope.

  G4FastSimulationManager(G4Envelope *anEnvelope,
        G4bool        IsUnique = FALSE);
  // This is the only constructor. In this constructor you specify 
  // the envelope by giving the G4Region (typedef-ed as G4Envelope)
  // pointer. The G4FastSimulationManager object will bind itself to
  // this envelope and will notify this G4Region to become an envelope.
  // If you know that this region is used for only one logical volume,
  // you can turn the IsUnique boolean to "true" to allow some optimization. 
  //
  // Note that if you choose to use the G4VFastSimulationModel(const G4String&,
  // G4Region*, G4bool) constructor for you model, the G4FastSimulationManager
  // will be constructed using the given G4Region* and G4bool values of the
  // model constructor.
