Inside the WeatherFragment all the main operations happen, it send the request to ApiHelper class and receive the response from it using WeatherForeCastCallBacks then update the views.

The user can add or remove cities from CitiesActivity.

ApiHelper mange the API requests, send request data for the ApiInterface and receive the response then store the result if needed then send the data via callbacks.
