* Detecting single, double, and two-finger taps using UIGestureRecognizer

* Zooming in response to taps

2_Autoscroll adds a thumbnail scroll view, and demonstrates:

* Use of the canCancelContentTouches property to track moving touches in a subview of a scroll view

* How to implement autoscrolling in response to a subview being dragged

3_Tiling demonstrates:

* How to subclass UIScrollView to add content tiling

* Reusing tiles to optimize performance and memory use

* Changing the resolution of the content in response to zooming
