title: IRRE relations from tt_content to tt_content in fluid styled content
body: <p>I have a fluid_styled_content element and they have IRRE elements which are also fluid_styled_content elements. How can I get the IRRE elements?</p>
  
  <p>At the moment I am trying to get them with a custom DataProcessor but I don't know how to actually get the elements. It looks like, that the parent element stores the amount of children and the children are storing the uid of the parent in the foreign_field. Any ideas?</p>
  
  <p>I though about the <code>ContentObjectRenderer</code> which I do have in the DataProcessor, but as I sad, I don't know how to actually get the elements. I tried <code>$cObj-&gt;cObjGet</code> but it didn't worked.</p>
