        Render a given resource. See L{IResource}'s render method.

        I delegate to methods of self with the form 'render_METHOD'

        request. Examples: render_GET, render_HEAD, render_POST, and
        so on. Generally you should implement those methods instead of
        overriding this one.

        render_METHOD methods are expected to return a byte string which will be
        the rendered page, unless the return value is C{server.NOT_DONE_YET}, in
        which case it is this class's responsibility to write the results using
        C{request.write(data)} and then call C{request.finish()}.

        Old code that overrides render() directly is likewise expected
        to return a byte string or NOT_DONE_YET.
