 * This class is an implementation of an Action Map for KDE.
 *
 *
 * What is an Action Map?
 *
 * Almost every web page has a site map. According to Wikipedia, 
 * a site map "helps visitors, and search engine robots, to find
 * pages on the site". Similar an Action Map should help the
 * user to find actions (i.e. functions or menu items) in an application.
 *
 * More concrete an Action Map is a dialog with a list of all 
 * actions (i.e. make text bold, save file or insert image) 
 * that can be performed in the application at its current state. 
 * Additionally there is a search box at the top of the list so
 * that the user can search the list easily for a special action. 
 * The action is executed by clicking on it. Disabled actions are
 * grayed out and cannot be clicked. The dialog is modeless so that 
 * it can always be open and the normal usage of the application is not disturbed.
