   * This sample demonstrates how to access and add Bookmarks to a Map.

   * and then some {@link Bookmark}s are added to that list, each with a name and
   * a {@link Viewpoint}.
   * <p>
   * To set the Map's Viewpoint to that of a Bookmark, select a Bookmark from the
   * BookmarkList, call the {@link Bookmark#getViewpoint} method, and pass that to
   * {@link MapView#setViewpoint}.
