 Class name: ctkNetworkConnectorZeroMQ
 This class is the implementation class for client/server objects that works over network
 with xml-rpc protocol. The server side part also create a new ID named REGISTER_SERVER_METHODS_XXX
 (where the XXX is the port on which run the server) that allows you to register your own remote
 callbacks. The library used is qxmlrpc.
