This class provides a collection for partial CUI files. 

This class only lists and controls the partial menu list stored in a menu file; it does not perform a full load or unload of a partial menu, nor does it verify the existence of the menu file (on Add). It also does not perform a merge of toolbars, pop menus, and ribbon panels to the workspaces. It should generally not be used to add or remove partial menus.
