 /**
 * @brief The 'QmitkMxNMultiWidget' is a QWidget that is used to display multiple render windows at once.
 *        Render windows can dynamically be added and removed to change the layout of the multi widget. This
 *        is done by using the 'ResetLayout'-function to define a layout. This will automatically add or remove
 *        the appropriate number of render window widgets.
 *        Several functions exist to retrieve specific render window(s) (widgets) by their position or name.
 *
 *        The class uses the 'DisplayActionEventBroadcast' and 'DisplayActionEventHandler' classes to
 *        load a state machine and set an event configuration. PACS mode is used per default.
 *        Using the 'Synchronize' function the user can enable or disable the synchronization of display action events.
 *        See 'DisplayActionEventFunctions'-class for the different synchronized and non-synchronized functions used.
