34 // This class is the abstract base class which represents a trajectory of
35 // a particle tracked.
36 // Its concrete class includes information of
37 // 1) List of trajectory points which compose the trajectory,
38 // 2) static information of particle which generated the
39 // trajectory,
40 // 3) trackID and parent particle ID of the trajectory,
