// Class description:
|
|
//
|
|
// This class represents the trajectory of a particle being tracked.
|
|
// It includes information of:
|
|
// 1) List of trajectory points which compose the trajectory;
|
|
// 2) Static information of the particle which generated the
|
|
// trajectory;
|
|
// 3) Track ID and parent particle ID of the trajectory.
