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