title: How can I drag a UICollectionViewCell from one UICollectionView to another UICollectionView?
body: <p>I am making an iPad application. On one page of this application, there is a UICollectionView on the left-hand side and another UICollectionView on the right hand side. Each UICollectionView is one column wide.</p>
  
  <p>The functionality I desire is as follows:
  Each UICollectionViewCell on the left hand side should be able to be dragged to the UICollectionView on the right hand side. If this is not possible, then at least a UICollectionViewCell should be able to be dragged out of the left UICollectionView and then I'll handle having it appear in the righthand UICollectionView.</p>
  
  <p>Is this functionality possible? If so, how would I go about implementing it?</p>
