   * This sample demonstrates how to change the Map's Basemap.
   * <p>
   * {@link Basemap} is beneath all other layers on a {@link Map} and is used to
   * provide visual reference for all other layers.
   * <h4>How it Works</h4>
   * 
   * A Map is created using an initial Basemap, latitude and longitude, and a
   * scale at which to view the Map. When a Basemap is selected, it is set to a
   * new Map and that Map is set to the {@link MapView}.
