// G4VUserTrackInformation
//
// Class Description:
//
//  Abstract class which the user can derive his/her own concrete
// class for toring user's information associating with a G4Track
// class object.
//
//  It is user's responsibility 
//   1) Construct a concrete class object and set the pointer to
//     proper G4Track object
//   2) Concrete class derived from this class is expected to use G4Allocator
//     for memory management or something equivarent for performance reason
//
//  To set a pointer of a concrete class object to G4Track in
// G4UserTrackingAction concrete implementation, given the G4Track
// object is available only by "pointer to const", SetUserTrackInformation()
// method of G4TrackingManager is available.
//
//  The concrete class object is deleted by Geant4 kernel when
// associated G4Track object is deleted.
