+// Specifies the state of the G4 application
+//
+// States:
+//  PreInit
+//    At the very begining of the Application. G4StateManager starts
+//    with this state. G4Initializer changes this state to Init when
+//    G4Initializer::Initialize() method starts. At the moment of
+//    the state change of PreInit->Init, no material, geometrical,
+//    particle or physics process has been initialized.
+//  Init
+//    During the G4Initializer::Initialize() method. G4Initializer
+//    changes this state to Idle when all initialization procedures
+//    are successfully Done.
+//  Idle
+//    Ready to start "BeamOn". G4RunManager changes this state to
+//    GeomClosed when G4RunManager::BeamOn() method starts and
+//    G4GeometryManager::CloseGeometry() is Done. At the end of
+//    BeamOn() method, G4RunManager will reset the application state
+//    to Idle after G4GeometryManager::OpenGeometry() is Done.
+//  GeomClosed
+//    G4 is in this state between G4GeometryManager::CloseGeometry()
+//    and G4GeometryManager::OpenGeometry(), but no event is in 
+//    progress. At the begining of each event (construction of a
+//    G4Event object and primary particle generation), G4RunManager
+//    changes this state to EventProc and resets to GeomClosed state
+//    when G4EventManager::ProcessOneEvent() is over.
+//  EventProc
+//    Processing an event.
+//  Quit
+//    G4 is in this state when the destructor of G4RunManager is invoked.
