SDLE = Service Delivery Locator Engine
Queries the Tomato server and find the service body that seems to cover a geopolitical location.
To test locally you can do the following (this requires you have ngrok and python installed):
> python -m SimpleHTTPServer 8008
> ngrok http 8008
You must use ngrok to test the KML layering feature because Google Maps needs to be able to pull the data from a public server.
