 * A control point is a UPnP term for "client".

 * This control point specifically handles Internet Gateway Devices (routers in UPnP terminology).
 * It queries the device for its port mapping service (an instance of a WanIPConnection or WanPPPConnection service).
 * Once the service is found, it can be used from the Manager class to configure port mappings.
