0031 // Class description:
0032 //
0033 // This is an interface for an object which can be called to kill a track.
0034 // The type it provides is needed in case importance biasing and scoring
0035 // is done at the same time.
0036 // For navigation in the parallel geometry which is done by the importance
0037 // biasing process (it derives from G4ParallelTransport), importance biasing
0038 // has to be done before scoring (to score the correct volume).
0039 // But since scoring would not be called if the importance biasing kills a
0040 // track, it only tells a G4VTrackTerminator to kill the track.
0041 // The scoring process implements the interface G4VTrackTerminator
0042 // and is now able to kill the track after it has performed the scoring.
