title: Clover PHPUnit coverage report is including coverage for unwanted file
body: <p>I have just set up CloverPHP into my Jenkins job. </p>
  
  <p>I am using PHPUnit to generate the clover report and it seems to all be working apart from the coverage report which is showing the file</p>
  
  <pre><code>/usr/share/php/SymfonyComponents/YAML/sfYamlInline.php 
  </code></pre>
  
  <p>as part of the report. I'm not sure where this is coming from, my guess is that PHPUnit or XDebug is including it. Obviously this is not part of my own code base so I am not interested in it. It is affecting the overall metrics produced by my project.
  Is there a way of excluding this file from the report?</p>
  
  <p>Many thanks,

  <p><strong>Edit</strong> </p>
  
  <p>The answer is to use a phpunit xml configuration file which can contain a filter blacklist.
