   * <@ArcGISMapImageLayer> which as multiple sub-layers. The application allows

   * <p>
   * You gain access to the sub-layers from the
   * <@ArcGISMapImageLayer.getSubLayers()> method which returns a <@SubLayerList>.
   * The <@SubLayerList> is a modifiable list of <@ArcGISSubLayers> which gives
   * you access to determine if the layer is visible or not and to turn on or off
   * the layers visibility.
