title: Instagram private InstagramAPI\Instagram::_setUser() error
body: <p>I'm trying to implementing <code>https://github.com/mgp25/Instagram-API</code> on laravel and after successful login in Instagram i must to use <code>_setUser</code> to use exiting data after login, for example:</p>
  
  <pre><code>public function check()
  {
      $username = 'XXX';
      $password = 'XXX';
      $ig = new Instagram();
      try {
          $ig-&gt;_setUser($username, $password);
      } catch (\Exception $e) {
          echo 'Something went wrong: '.$e-&gt;getMessage()."\n";
          exit(0);
      }
  }
  </code></pre>
  
  <p>in this code i get this error:</p>
  
  <pre><code>"Call to protected method InstagramAPI\Instagram::_setUser() from context 'App\Http\Controllers\InstagramController'"
  </code></pre>
