/**
Workaround for iOS 6 setTimeout bug using requestAnimationFrame to simulate timers during Touch/Gesture-based events
Author: Jack Pattishall (jpattishall@gmail.com)
This code is free to use anywhere (MIT, etc.)

Note: UIWebView does not support requestAnimationFrames. If your timer is failing during a scroll event,
take a look at https://gist.github.com/ronkorving/3755461 for a potential workaround.

Usage: Pass TRUE as the final argument for setTimeout or setInterval.
