    Description:
    This sample demonstrates how to add an ArcGISTiledMapServiceLayer
    to your Map using the ArcGIS API for Flex.  The tiled layer is
    typically used as a basemap layer in the map and its source is
    a map service that has been cached or has map tiles.
    This map is the World Topographic map service from ArcGIS Online.

    You can browse the ArcGIS.com site for additional online basemap and reference
    map services or publish your own geographic data as a service using ArcGIS Server.
