Small code improvements
Added a check so only instances of ContextualUndoView are swipeable.  Allowing for mixing of view types with some un-dissmissible
Added support for auto deletion after a delay when an item is removed by swipe, and two example activities
Added shouldAnimate method
Removed TextSwitcher and CountDownTimer, now uses Handler.postDelayed().
