title: Aligning right to left on UICollectionView
body: <p>this is a pretty straightforward question, but I haven't been able to find a definitive answer to it on SO (if I missed it, please correct me). </p>
  
  <p>Basically, my question is: <strong><em>Is it possible to align <code>UICollectionView</code> row contents from right to left instead of from left to right?</em></strong></p>
  
  <p>In my research I've seen answers suggesting subclassing <code>UICollectionViewFlowLayout</code>, but I haven't been able to find an example where one was created for right-alignment.</p>
  
  <p>My goal is to have 2 collection views set up like this:</p>

  <p>Any help is greatly appreciated!</p>
