+//
+//    A data representation class, used to hold the data for
+//    a single level of the Navigation history tree.
+//
+//    This is the body of a handle/body pair of classes,
+//     that implement reference counting for NavigationLevels.
+//    The corresponding handle class is G4NavigationLevel
+//
+// History:

+//  1 October 1997,   J.Apostolakis:    Initial version.
