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