//  This is the base class of one of the user's optional action classes.
// The two methods BeginOfEventAction() and EndOfEventAction() are invoked
// at the beginning and the end of one event processing. These methods are
// invoked by G4EventManager.
//  Be aware that BeginOfEventAction() is invoked when a G4Event object is
// sent to G4EventManager. Thus the primary vertexes/particles have already
// been made by the primary generator. In case the user wants to do something
// before generating primaries (i.e., store random number status), do it in
// the G4VUserPrimaryGeneratorAction concrete class.
