/**
 * This class is both a List and an Action although it purpose is not to serve
 * as a true executable Action.
 * Its purpose is to allow menu items, toolbars and toolbuttons etc to be built
 * from a model mode up of Actions where each Action is either an executable
 * action to be shown as a menu item or toolbutton. However should an Action
 * be of this specific class it provides the name and icon only for building
 * a submenu node or dropdown toolbutton and contains a list of further
 * Actions to be contained in that subnode.
