// Class description:
//
// This is a concrete class of G4UIsession.
// This class object is instantiated by G4UImanager every time
// the "/control/execute macro_file" command is executed.
// Also, in the case of pure batch mode with a macro file,
// this class can be used as other ordinary G4UIsession
// concrete classes, i.e. SessionStart() is invoked in main().
