title: How to use a vendor class in Laravel?
body: <p>I would like to use this package <a href="https://github.com/FineUploader/php-traditional-server/" rel="nofollow">https://github.com/FineUploader/php-traditional-server/</a> in my Laravel project. So I modified composer.json file like that:</p>
  
  <pre><code>"require": {
      "php": "&gt;=5.5.9",
      "laravel/framework": "5.2.*",
      "fineuploader/php-traditional-server": "1.0.0"
  }
  </code></pre>
  
  <p>And run a compose update command. But how can I use <code>UploadHandler</code> class (declared in handler.php of the package) on my Controller?</p>
