Basic networking

https://www.tutorialspoint.com/http/http_requests.htm

http://www.json.org

https://github.com/Alamofire/Alamofire

You should do the following:

1. Read about HTTP requests.
2. Read about JSON.
3. Install Google Chrome and Postman extension.
4. Execute GET request with http://gitlab.faifly.com/ios-general/ios-tutorial/uploads/75727472327ca7b210bb1d904438a2d7/tutorial.json URL. You should see JSON with a list of organizations.
5. Create a new branch from develop called feature/basic_networking.
6. Create a new class called RequestManager, which is subclass of NSObject.
7. Implement fetchOrganizations static method, which accepts one argument - a closure (block) with a single parameter - [String : AnyObject]. It should send a GET request to a URL specified above and return the response with the help of the closure.
8. Add a new button in OrganizationInfoViewController, called “Fetch organizations”. Upon tapping that button you should call fetchOrganizations method from RequestManager, parse it into the database and present an action sheet with a list of organizations. After selecting an organization you should return to MainViewController and its table should be reloaded with appropriate organization. Request should be done with Alamofire.
9. Create a pull request.
