PaperFoldMenuController is a UITabBarController replacement, but displays the view controllers in a table view on the left side of the screen. This table view is shown/hidden using PaperFold-for-iOS. Selecting from the menu on the left changes the view controller on the right. PaperFoldMenuController uses view controller containment.
