// G4VUserEventInformation
//
// Class Description:
//
//  Abstract class which the user can derive his/her own concrete
// class for toring user's information associating with a G4Event
// class object.
//
//  It is user's responsibility to construct a concrete class object 
// and set the pointer to proper G4Event object.
//
//  To set a pointer of a concrete class object to G4Event in
// G4UserEventingAction concrete implementation, given the G4Event
// object is available only by "pointer to const", SetUserEventInformation()
// method of G4EventManager is available.
//  Alternatively, the user may modify GenerateEvent() method of 
// his/her own RunManager. 
//
//  The concrete class object is deleted by Geant4 kernel when
// associated G4Event object is deleted.
