           * Why we need to support this ? Because we provide tree views, which aren't plain.
           *
           * Now, how does this logic work. It will get the first element on the list (with no filename),
           * following the previous example say "/home/foo" and set it as the top most url.
           *
           * After this, it will iterate over the rest of items and check if this URL (topmost url)
           * contains the url being iterated.
           *
           * As you might have guessed it will do "/home/foo" against "/boot/grub" (again stripping
           * filename), and a false will be returned. Then we upUrl the top most url, resulting in
           * "/home" against "/boot/grub", what will again return false, so we upUrl again. Now we
           * have "/" against "/boot/grub", what returns true for us, so we can say that the closest
           * common ancestor of both is "/".

 /**
  * @class KUrlNavigator kurlnavigator.h <KUrlNavigator>
  *
  * @brief Widget that allows to navigate through the paths of an URL.
  *
  * The URL navigator offers two modes:
  * - Editable:     The URL of the location is editable inside an editor.
  *                 By pressing RETURN the URL will get activated.
  * - Non editable ("breadcrumb view"): The URL of the location is represented by
  *                 a number of buttons, where each button represents a path
  *                 of the URL. By clicking on a button the path will get
  *                 activated. This mode also supports drag and drop of items.
  *
  * The mode can be changed by clicking on the empty area of the URL navigator.
  * It is recommended that the application remembers the setting
  * or allows to configure the default mode (see KUrlNavigator::setUrlEditable()).
  *
  * The URL navigator remembers the URL history during navigation and allows to go
  * back and forward within this history.
  *
  * In the non editable mode ("breadcrumb view") it can be configured whether
  * the full path should be shown. It is recommended that the application
  * remembers the setting or allows to configure the default mode (see
  * KUrlNavigator::setShowFullPath()).
  *
  * The typical usage of the KUrlNavigator is:
  * - Create an instance providing a places model and an URL.
  * - Create an instance of QAbstractItemView which shows the content of the URL
  *   given by the URL navigator.
  * - Connect to the signal KUrlNavigator::urlChanged() and synchronize the content of
  *   QAbstractItemView with the URL given by the URL navigator.
  *
  * It is recommended, that the application remembers the state of the QAbstractItemView
  * when the URL has been changed. This allows to restore the view state when going back in history.
  * KUrlNavigator offers support for remembering the view state:
  * - The signal urlAboutToBeChanged() will be emitted before the URL change takes places.
  *   This allows the application to store the view state by KUrlNavigator::saveLocationState().
  * - The signal urlChanged() will be emitted after the URL change took place. This allows
  *   the application to restore the view state by getting the values from
  *   KUrlNavigator::locationState().
