title: Animate a UICollectionView cell on selection
body: <p>I have a basic grid in a <code>UICollectionView</code>. It's a simple 2 column, multiple row layout using the <code>UICollectionViewDelegateFlowLayout</code>. When a cell is selected, I want to dim the background, float the cell to the center of the screen and then have a workflow based on the selected cell. I'm fairly new to <code>UICollectionViews</code>, and I'm not sure of the best way to go about this.</p>
  
  <p>Should I have a custom layout of the <code>UICollectionView</code> for when a cell is selected? </p>
  
  <p>Or is there a way I can animate the selected cell without having to create a new layout</p>
  
  <p>If anyone can just get me going on the right direction, I think I'll be good to research how to execute it.</p>
