# A "combined" renderer is one that renders subtab HTML directly inside the
# HTML list of tabs, rather than two separate HTML lists for tabs and subtabs.
#
# This class is meant to be subclassed.  It encapsulates the code
# common to all combined renderers so that it doesn't have to be recoded
# everytime.
