/**
 * This sample demonstrates how to display a Map.
 * <p>
 * A {@link Basemap} is beneath all other layers on a {@link Map} and is used to
 * provide visual reference for all other layers.
 * <p>
 * A Map needs to be set to the MapView in order for it's layers to be
 * displayed.
 * <h4>How it Works</h4>
 * 
 * A Map is created using a Basemap and the {@link MapView#setMap} method is
 * used to apply that Map to the view.
 * <p>
 * By default, a Map supports basic zooming and panning operations.
