Overview

This is the base class for all renderers.

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).
