Code example:
this.gwuSvr = gwu.NewServer("guitest", "0.0.0.0:3434")
this.gwuSvr.AddSessCreatorName("login", "Login Window")
this.gwuSvr.AddSHandler(MySessHandler{this, nil})
this.gwuSvr.Start("login")
When Start is called, gowut opens a browser page to the ip and port that were specified in NewServer. In this case, it attempts (and fails) to connect to 0.0.0.0, because that isn't a real IP that can be connected to, it's just a way of saying "listen on all interfaces instead of just one."
