29 //
30 // A data representation class, used to hold the data for a single level
31 // of the Navigation history tree.
32 //
33 // This is the body of a handle/body pair of classes, that implement
34 // reference counting for NavigationLevels.
35 // The corresponding handle class is G4NavigationLevel
