  * a GUI of container widgets (like menus, toolbars, etc.) and container items
  * (menu items, toolbar buttons, etc.) from an XML document and action objects.
  *
  * Each KisKXMLGUIClient represents a part of the GUI, composed from containers and
  * actions. KisKXMLGUIFactory takes care of building (with the help of a KisKXMLGUIBuilder)
  * and merging the GUI from an unlimited number of clients.
  *
  * Each client provides XML through a QDomDocument and actions through a
  * KisKActionCollection . The XML document contains the rules for how to merge the
  * GUI.
  *
  * KisKXMLGUIFactory processes the DOM tree provided by a client and plugs in the client's actions,
  * according to the XML and the merging rules of previously inserted clients. Container widgets
  * are built via a KisKXMLGUIBuilder , which has to be provided with the KisKXMLGUIFactory constructor.
