     *  the same type. Most often one would use the index in conjunction with

     *  <code>addStyleForComponentType()</code> methods.
     * @param optional object StyleCollections styles,... Zero, one, or more StyleCollection
     *  objects that will be added to the newly created Component. Warning, this will
     *  result in copying the objects instead of referencing them as using
     *  <code>addStyle()</code> would do.
