 28 // Class description:
 29 //
 30 // This class represents the trajectory of a particle tracked.
 31 // It includes information of
 32 //   1) List of trajectory points which compose the trajectory,
 33 //   2) static information of particle which generates the
 34 //      trajectory,
 35 //   3) trackID and parent particle ID of the trajectory,
 36 //   4) Auxiliary points will be associated to G4SmoothTrajectoryPoint
 37 //      to assist drawing smoothly curved trajectory.
