    # A renderer is responsible for rendering an ItemContainer (primary or a sub_navigation) and its containing items to HTML.
    # It must be initialized with the current_navigation for the rendered ItemContainer and 
    # optionally with the current_sub_navigation (if the sub_navigation will be nested).
