react native redux saga增加日志功能

redux-logger地址：https://github.com/evgenyrodionov/redux-logger

目前Reac native项目中已经使用redux功能，异步中间件使用redux saga，但在处理时，也需要增加redux打印日志的功能，所以需要增加redux-logger功能

            {/* <Scene key='FittingCheck' component={FittingCheckContainer} title={I18n.t('App.UserRegister_Title')} hideNavBar={true} />
            <Scene key='FittingCheck' component={FittingCheckContainer} title={I18n.t('App.UserRegister_Title')} hideNavBar={true} /> */}

            <Scene key='FittingCheck' component={FittingCheckContainer} title={I18n.t('App.FittingCheck_Title')} hideNavBar={true} />
          </Scene>
        </Router>
      </Provider>
    );
  }
}

运行时，打开远程调试，可以在Chrome开发工具中看到日志信息

有了日志功能后，可以比较简单的查看到action的type及其他参数，也可以看到每一个action发生前与发生后state(reducers)的变化
