31 // Class description:
32 //
33 // A singleton class which stores the (volume) navigator used by
34 // the transportation process to do the geometrical tracking.
35 // It also stores a pointer to the propagator used in a (magnetic)
36 // field and to the field manager.
37 // The class instance is created before main() is called, and
38 // in turn creates the navigator and the rest.
