Using phpcrawl with Laravel 5.4

I am trying to use cuab's phpcrawl within Laravel 5.4 and have included it through composer using the package - https://packagist.org/packages/cuab/phpcrawl

I have tried running the sample code;

class MyCrawler extends PHPCrawler  
{ 
  function handleDocumentInfo($DocInfo)  
  { 
    if (PHP_SAPI == "cli"){
      $lb = "\n"; 
    } else {
      $lb = "<br />"; 
    }
    echo "Page requested: ".$DocInfo->url." (".$DocInfo->http_status_code.")".$lb; 
    echo "Referer-page: ".$DocInfo->referer_url.$lb; 

    if ($DocInfo->received == true) {
      echo "Content received: ".$DocInfo->bytes_received." bytes".$lb; 
    }
    else {
      echo "Content not received".$lb;  
    }

    echo $lb; 
    flush(); 
  }  
} 

$crawler = new MyCrawler(); 
$crawler->setURL("www.php.net"); 
$crawler->addContentTypeReceiveRule("#text/html#"); 
$crawler->addURLFilterRule("#\.(jpg|jpeg|gif|png)$# i"); 
$crawler->enableCookieHandling(true);  
$crawler->setTrafficLimit(1000 * 1024); 
$crawler->go(); 
$report = $crawler->getProcessReport(); 

if (PHP_SAPI == "cli") {
  $lb = "\n"; 
} else {
  $lb = "<br />"; 
}

echo "Summary:".$lb; 
echo "Links followed: ".$report->links_followed.$lb; 
echo "Documents received: ".$report->files_received.$lb; 
echo "Bytes received: ".$report->bytes_received." bytes".$lb; 
echo "Process runtime: ".$report->process_runtime." sec".$lb; 

But this throws multiple errors;

Class 'App\Http\Controllers\PHPCrawler' not found

How would you reference the correct namespace so that I can use the script within Laravel?
