title: UIRefreshControl pull-UP to refresh?
body: <p>I hooked up a NSFetchedResultController with a UITableViewController. </p>
  
  <p>I would love to implement UIRefreshControl at the BOTTOM of my UITableView. This means that my users will be scrolling down to the bottom of the table. Then the user will scroll up to trigger UIRefreshControl. </p>
  
  <p>Can this be done? I am not able to Google anything on this. </p>
