        This returns <LFXNetworkContext: 0x7fa692731b40> {name = LAN, isConnected = 0}, so the object is correctly created, however,
        in the SharedLightsManger, it doesn't connect to the network, or call any of the callback methods provided by the LFX Framework.
        Can this LFX network context and its method not be extracted into a seperate class like this? Or does it have to be created on each viewcontroller that is responsible for
        controlling lights? It would be really convenient to have it in a 'master' class and delegate the calls out from that*/
