title: Lumen (laravel) translation in controller
body: <p>I need to translate strings which are used in (email-)jobs and controllers.</p>
  
  <p>I read this: <a href="https://laravel.com/docs/5.2/localization" rel="nofollow">https://laravel.com/docs/5.2/localization</a> so I know you can get in in the view with:</p>
  
  <pre><code>echo trans("messages.welcome");
  </code></pre>
  
  <p>But it's an Lumen api and I do not use the view.</p>
  
  <p>How can i get the translator in a controller or a job.</p>
  
  <p>Thanks in advance!</p>
