// Class description:
//
// This class extends G4Trajectory, which includes the following:
//   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.
// The extended information, only publicly accessible through AttValues,
// includes:
//   4) physical volume and next physical volume;
//   5) creator process;
// ...and much more.
 
// Contact:
//   Questions and comments on G4Trajectory should be sent to
