30 // This class represents the trajectory of a particle being tracked.
31 // It includes information of:
32 // 1) List of trajectory points which compose the trajectory;
33 // 2) Static information of the particle which generated the
34 // trajectory;
35 // 3) Track ID and parent particle ID of the trajectory.
