// Class description:
//
// 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.
