// Class description:
//
// A class responsible for high level geometrical functions, and for
// high level objects in the geometry subdomain.
// The class is a `singleton', with access via the static method
// G4GeometryManager::GetInstance().
//
// Member data:
//
//   - fgInstance
//     Ptr to the unique instance of class
 
// 26.07.95, P.Kent - Initial version, including optimisation build
