title: Where to put custom/new class file in Laravel?
body: <p>I have PHP example on how to use Yelp Fusion API. It uses <a href="https://github.com/Yelp/yelp-api/blob/master/v2/php/lib/OAuth.php" rel="nofollow noreferrer"><code>OAuth.php</code> file</a> with several classes. In main example it is imported with</p>
  
  <pre><code>require_once('lib/OAuth.php');
  </code></pre>
  
  <p>Can I do the same in Laravel?</p>
  
  <p>Or I'd better provide namespace for <code>OAuth.php</code> file and put it somewhere on the tree? Where to put it?</p>
