Swipable UITableView (just like Tweetie)

In a recent Stack Overflow thread, the question came up how you can implement a table view where you can swipe over a cell to reveal another view behind it. Literally within the hour (how cool is that?), Tom Irving pointed to his  TGNWSwipeableTableView class that just does that. A sample app reveals the basics, and you can populate the view underneath with your own set of controls to your liking.

Tom’s implementation even fixes a problem Tweetie has, where you can’t swipe over the same row two times consecutively.
