    A <b>goog.ui.TabBar</b> is a subclass of <b>goog.ui.Container</b>,
    designed to host one or more <b>goog.ui.Tab</b>s.  The tabs in the
    first four tab bars on this demo page were decorated using the default
    tab renderer.  Tabs in the last two tab bars were decorated using the
    rounded tab renderer (<b>goog.ui.RoundedTabRenderer</b>).
