//
//  Description:
//    A singleton class which manages the Fast Simulation managers 
//    attached to envelopes.
//
//  History:
//    June 98: Verderi && MoraDeFreitas - "G4ParallelWorld" becomes
//             "G4FlavoredParallelWorld"; some method name changes;
//             GetFlavoredWorldForThis now returns a 
//             G4FlavoredParallelWorld pointer.
//    Feb 98: Verderi && MoraDeFreitas - First Implementation.

// Class Description:
// This a singleton class which provides the management of the G4FastSimulationManager

// ...
// ...
// G4GlobalFastSimulationManager* globalFSM;
// globalFSM = G4GlobalFastSimulationManager::getGlobalFastSimulationManager();
// ...
// ...

// Presently, you will mainly need to use the GlobalFastSimulationManager if you use ghost 
// geometries.

  //        myModel = gblManager->GetFastSimulationModel("MyModel");
  //    o note for the case of several models having the same name:
  //        - to get the first "MyModel" model:
  //             myModel1 = gblManager->GetFastSimulationModel("MyModel", 0);

  //        - When gblManager->GetFastSimulationModel("MyModel", myModel_n)
  //          returns a null pointer, no extra model with name "MyModel" exist.
