A ControlDataSender can send control signals to one or more receivers using a network connection. A single ControlDataSender can connect to multiple receivers, all identified by a UUID. The class is controlled using an ISystemControllerInterface; this interface is responsible for setting up connections to receivers. The ControlDataSender can send asynchronous requests to (all) the receivers and get a response back. Each response is identified with a request ID as well as the UUID of the responding receiver. The ControlDataSender can also receive status messages from the receivers.
