// G4RichTrajectory.hh
//
// 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
