//
// class description:
//   This class extends G4TrajectoryPoint.
//   From G4Trajectory, the following information is included:
//     1) Position (end of step).
//   The extended information, only publicly accessible through AttValues,
//   includes:
//     2) Auxiliary points, as in G4SmoothTrajectory.
//     3) Total energy deposit.
//     4) Remaining energy.
//     5) Process defining end of step.
//     6) Global time (from start of event) at pre- amd post-step.
//   ...and more.
