title: Extending the Content Query WebPart
body: <p>I'm wanting to have some data displayed on a SharePoint page which is essentially a Content Query WebPart, but with a few small changes:</p>
  
  <ul>
  <li>Filter on a dynamic date</li>
  <li>Paged Results</li>
  </ul>
  
  <p>Is it possible to do the modifications by extending the existing one or is there a component out there which will do that?</p>
