28// Class description:
29//
30// A class responsible for high level geometrical functions, and for
31// high level objects in the geometry subdomain.
32// The class is a `singleton', with access via the static method
33// G4GeometryManager::GetInstance().
34//
35// Member data:
36//
37// - fgInstance
38// Ptr to the unique instance of class
