code: function(username, password) {
        var restler_defaults = { baseURL: config.baseUrl };
        var RestlerService = restler.service(default_init, restler_defaults, api);
  
        return new RestlerService(username, password);
      }
docs: Can't use multilple instances of Reslter services  Because each instance shares the defaults and the only way to set the username & password is to use the defaults each instance will actually be the same  So instead when we create another instance of a Stallion service we'll actually create a seperate instance of a Restler service
