The Portal Manager for 2112Portals will keep track and persist settings, the
Portal Admin is applying to Windows (such as width, height, X, Y) or Menus.
It bases on a pluggable architecture that allows all kind of persistency.
Simply implement the required methods (kind of Interface Implementation)
 in a file called portalPersister.js
