+Package implementing the viewmanager of the eric6 IDE.

+The viewmanager is responsible for the layout of the editor windows. This is
+the central part of the IDE. In additon to this, the viewmanager provides all
+editor related actions, menus and toolbars.
+
+View managers are provided as plugins and loaded via the factory function. If
+the requested view manager type is not available, tabview will be used by
+default.
