---Purpose: Add a new top-level Z layer to the view with ID
-- <theLayerId>. The z layer mechanism allows to display
-- structures in higher layers in overlay of structures in lower layers.
-- The layers in a particular view should be managed centrally
-- by its view manager so to avoid IDs mismatching and provide correct
