        Displays @ref orxonox::Notification "Notifications" using CEGUI.

        Apart form the parameters inherited by the @ref orxonox::NotificationQueue "NotificationQueue", there are some more parameters that influence the behavior of the NotificationQueueCEGUI:
        - @b displaySize The size of the window that displays the NotificationQueue.
        - @b position The position if the window that displays the NotificationQueue.
        - @b alignment The horizontal alignment of the displayed Notifications.
        - @b fontSize The font size of the displayed Notifications.
        - @b fontColor The font color of the displayed Notifications.
