title: Problems using PackageLoader to load the wrench class
body: <p>I am trying to load the Wrench library using <a href="https://github.com/Wilkins/composer-file-loader" rel="nofollow noreferrer">PackageLoader</a> and I can't get it to work. My code is below.</p>
  
  <pre><code>include __DIR__.'/PackageLoader.php';
  $loader = new PackageLoader\PackageLoader();
  $loader-&gt;load(__DIR__."/vendor/wrench/wrench");
  
  $app = new class implements \Wrench\Application\DataHandlerInterface
  {
      public function onData(string $data, \Wrench\Connection $connection): void
      {
          $connection-&gt;send($data);
      }
  };
  </code></pre>
  
  <p>I get this error</p>
  
  <blockquote>
    <p>Fatal error: Interface 'Wrench\Application\DataHandlerInterface' not found in C:\Users\desbest\Documents\UniServerZ\www\sugarchat\includes\actions.php on line 13</p>
  </blockquote>
  
  <p>It finds the <code>composer.json</code> file though when I load the library.</p>
  
  <p>How do I fix this?</p>
