      Returns:

    - #### getUtils

          public org.richfaces.util.RendererUtils getUtils()

      Due to big number of common utility methods, base renderer divide to 2 classes - renderer and utils. since use static methods of utility class breack object paradigm, we use getter for concrete util instance. Developer can override any utility metod in 2 stages : 1) Create subclass of `RendererUtils` and override utility method. 2) Override this method for return instance of such subclass.

        Returns the utils.
