// class description:
//   This class represents the trajectory of a particle tracked.
//   It includes information of 
//     1) List of trajectory points which compose the trajectory,
//     2) static information of particle which generated the 
//        trajectory, 
//     3) trackID and parent particle ID of the trajectory,
