    Add a Dynamic Layer based on an existing ArcMap and ArcGIS Server map service ArcGISDynamicMapServiceLayer 
    sub-layer (specifically the 'cities' or [0] sub-layer). A Dynamic Layer is a web request where the client 
    application issues an ArcGIS Server command to generate an on-the-fly layer for display in the Map Control. 
    Note: the DisableClientCaching is set to true so that what ever is returned from the server will be displayed.
        
    The following high-level things are occuring to create the Dynamic Layer: 
    (1) create a DynamicLayerInfo object and set the .ID and .Source Properties
    (2) add that DynamicLayerInfo object to the ArcGISDynamicMapServiceLayer .DynamicLayerInfos collection
    (3) create a LayerDrawingOptions object and set the .LayerID and .Renderer Properties
    (4) add that LayerDrawingOptions object to the ArcGISDynamicMapServiceLayer .LayerDrawingOptions collection
