// Class description:
//
// This class is identical to G4RichTrajectory class, but uses the
// singleton G4Allocator so that the master thread can safely
// delete the object instantiated by worker threads in sub-event
// parallel mode. This class object should be instantiated as
// a clone of G4RichTrajectory object.
