class HShape from PTopoDS inherits ExternShareable from ObjMgt

    ---Purpose: The PTopoDS_HShape is the Persistent view of a TopoDS_Shape.
  -- This can be a vertex, an edge, a wire, a face, a shell, a solid and so on.
 -- It can be shared by other objects.
    --  a  HShape contains :
    --          
    --          - a reference to a TShape.
    --          
    --          - a Location  to put the TShape in  a local coordinate
    --          system.
    --          
    --          - an Orientation.
    --          
    --          It inherits from ExternShareable, so that it can be shared
    --          by other objects located outside the container.
