 * This sample demonstrates how to set the initial location when the Map is
 * created.
 * <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 a Basemap, a latitude and longitude, along with a
 * level of detail. The latitude and longitude give the initial location and the
 * level of detail represents scale.
