// class description:
//
//  This is a concrete class of G4VTrajectory which represents a trajectory of a ray.
//  This class is used by G4RayTracer. Objects of this class are created by G4RTTrackingAction.
//  This class does not have concrete implementations of draw and print methods but
// information stored in this class is used by determining a colour of a pixel of the picture.
