title: Class not found in ProviderRepository.php error with composer install
body: <p>I'm currently in the process of trying to include this package in my Laravel app: <a href="https://github.com/tappleby/laravel-auth-token" rel="noreferrer">https://github.com/tappleby/laravel-auth-token</a></p>
  
  <p>I included <code>"tappleby/laravel-auth-token": "0.3.*"</code> in composer.json, like this:</p>
  
  <pre><code>"require": {
      "laravel/framework": "4.2.*",
      "intervention/image": "dev-master",
      "laracasts/flash": "~1.0",
      "laracasts/validation": "1.1.*",
      "tappleby/laravel-auth-token": "0.3.*"
  }
  </code></pre>
  
  <p>And I added <code>'Tappleby\AuthToken\AuthTokenServiceProvider'</code> and <code>'AuthToken'=&gt;'Tappleby\Support\Facades\AuthToken','AuthTokenNotAuthorizedException' =&gt;'Tappleby\AuthToken\Exceptions\NotAuthorizedException'</code> to <code>app/config/app.php</code>.</p>
  
  <p>Afterwards I ran <code>composer install</code>. This is the way I always added packages, but now I get an error every time: <code>[RuntimeException]<br>
    Error Output: PHP Fatal error:  Class 'Tappleby\AuthToken\AuthTokenServiceProvider' not found in /var/www/example.com/htdocs/vendor/laravel/framework/src/Illuminate/Foundation/ProviderRepository.php on line 157</code> </p>
