# Renders an ItemContainer as a <div> element and its containing items as
# <a> elements.
# It only renders 'selected' elements.
#
# By default, the renderer sets the item's key as dom_id for the rendered
# <a> element unless the config option <tt>autogenerate_item_ids</tt> is
# set to false.
#
# The id can also be explicitely specified by setting the id in the
# html-options of the 'item' method in the config/navigation.rb file.
# The ItemContainer's dom_attributes are applied to the surrounding <div>
# element.
