//
//  Description:
//    A singleton class which manages the Fast Simulation managers 
//    attached to envelopes. Implementation.
//
//  History:
//    June 98: Verderi && MoraDeFreitas - "G4ParallelWorld" becomes
//             "G4FlavoredParallelWorld"; some method name changes;
//             GetFlavoredWorldForThis now returns a 
//             G4FlavoredParallelWorld pointer.
//    Feb 98: Verderi && MoraDeFreitas - First Implementation.
//    March 98: correction to instanciate dynamically the manager
//    May 07: Move to parallel world scheme
