        This sample shows how to load KML or KMZ files onto the map.
        The spatial IO module is used to parse the features in KML/KMZ file into GeoJSON.
        KML ground overlays are returned as either an ImageLayer or an OgcMapLayer depending on if the ground overlay is a static image or a WMS service.
        Custom images for icons are also captured and need to be added to the map resources before loading the features on the map.
