e of the multiplexing
              look and feel UI classes (for example, <code>MultiButtonUI</code>).
              The UI object from the auxiliary look and feel can call the <code>getUIs</code>
              method of the returned object to obtain an array containing a complete list
              of all UI objects handled by the multiplexing UI. The first element
              is guaranteed to be the UI created from the default look and feel.
