// Class description:
//
// This is a class for mandatory control of the Geant4 kernel.
// This class implements Worker behavior in a MT application.
//
// This class is constructed by G4MTRunManager. If a user uses his/her own
// class instead of G4MTRunManager, this class must be instantiated by at the
// very beginning of the application and must be deleted at the very end.
// Also, the following methods must be invoked in the proper order:
//       DefineWorldVolume()
//       InitializePhysics()
//       RunInitialization()
//       RunTermination()
//
// User must provide his/her own classes derived from the following
// abstract class and register it to the RunManagerKernel:
//       G4VUserPhysicsList - Particle types, Processes and Cuts
//
// G4MTRunManagerKernel does not have an event loop. Handling of events
// is managed by G4RunManager.
//
// This class re-implements only the methods that require special treatment
// to implement worker behavior
