//  This is a concrete class of G4UIsession.

//  This class object is instantiated by G4UImanager at every time 
//  when "/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().
