title: Where are Laravel 5.1 Repositories?
body: <p>I was going through socialite tutorial which is created by Laravel 5 and I'm using Laravel 5.1 and I saw that there is a file in tutorial like <code>AuthenticateUser.php</code> in repositories folder. But repositories folder doesn't even exist in Laravel 5.1. Where I should create a file <code>AuthenticateUser.php</code> in Laravel 5.1?</p>
