+/**
+*  CGSShimmedView is used by CGSPluginAndViewIdCache to provide view-framework
+*  with all existing plugin views immediately in GS start-up. Shimmed views
+*  are used to cache actual views: in case GS view is opened outside GS
+*  application while GS is not running in the background, view-framework needs
+*  the requested view to exist immediately after GS start-up. This is a problem
+*  as GS loads plugins asynchronously after GS start-up. Therefore we provide
+*  view-framework with shimmed views in the GS start-up instead of the actual
+*  views. Afterwards, when each plugin is loaded, we replace the shimmed view
+*  representing the plugin with a real view provided by the loaded plugin.
+*  (Each plugin is normally also a view).
+*
+*  Shimmed views are only used and needed for enabling external GS plugin
+*  view launch.
+*
+*  See CGSPluginAndViewIdCache for details.
+*
+*  @since Series60_3.1
