title: Want UITableView to "snap to cell"
body: <p>I am displaying fairly large images in a <code>UITableView</code>. As the user scrolls, I'd like to the table view to always snap the center-most photo in the middle. That is, when the table is in a resting state, it will always have a <code>UITableViewCell</code> snapped to the center. </p>
  
  <p>How does one do this?</p>
