// Class G4TrackTerminator
//
// Class description:
//
// This is an interface for an object which maybe told to kill a track.
// The type it provides is needed in case importance biasing and
// scoring is done at the same time. 
// For navigation in the parallel geometry which is done 
// by the importance biasing process (it derives from G4ParallelTransport)
// importance biasing has to be done before scoring (to score the correct
// volume). But since scoring would not be called if the importance
// biasing kills a track it only tells a G4TrackTerminator to kill the 
// track. The scoring process implements the interface G4TrackTerminator
// and is now able to kill the track after it has done the scoring.
