  Add a Map Control with an ArcGISTiledMapServiceLayer and a FeatureLayer. The ArcGISTiledMapsServiceLayer 
  is the first Layer in Map.LayerCollection and is drawn on the bottom. The FeatureLayer is then added and 
  draws on top. Set the Map.Extent to zoom to the middle of the Atlantic Ocean.
    
  Setting the Map.TimeExtent acts like a Where clause in that only those features/records that fall
  within the set TimeSlider.Value (which is a narrowed TimeExtent) will then be shown. By Binding the 
  Map.TimeExtent to the TimeSlider.Value Property, the Map will automatically update as the thumb(s) on 
  the TimeSlider moves.

    The FeatureLayer contains Hurricane data from NOAA as Markers (aka. Points). The Where clause is 
    optional. It is necessary when more that 500/1000 records returned. In ArcGIS Server 9.3.1 and prior, 
    the default maximum is 500 records returned per FeatureLayer. In ArcGIS Server 10 the default is 1000. 
    This setting is configurable per map service using ArcCatalog or ArcGIS Server Manager (on the Parameters
    tab). 
          
    The Where clause gets only hurricane data for Alberto (a much smaller subset of the entire service).
    
    Specify the Outfields Property to specify which Fields are returned. Specifying the wildcard (*) 
    character will return all Fields.
