//
// class description:
//  This is an interface class among the event,  the track
//  and the tracking category. It handles necessary 
//  message passings between the upper hierarchical object, which 
//  is the event manager (G4EventManager), and lower hierarchical 
//  objects in the tracking category. It receives one track in an 
//  event from the event manager and takes care to finish tracking it. 
//  Geant4 kernel use only.
