title: How Can I Animate the Size of A UICollectionViewCell on Scroll so the middle one is largest?
body: <p>I have a UICollectionView that shows several rows with one, full-width column (looks like a UITableView)</p>
  
  <p>What I'd like to achieve is something similar to this:</p>
  
  <p><img src="https://i.stack.imgur.com/BCZdm.png" alt="UICollectionView with animations"></p>
  
  <p>... where the middle cell has a much greater height. As the user scrolls up and down, the cells before and after the middle cell animate back to the default height for the given cell.</p>
  
  <p>Can somebody outline how I should approach this problem?</p>
