setTimeout workaround for iPad and iOS6
/**
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.

iOS6 webkit timer bug workaround
(function (window) {
// This library re-implements setTimeout, setInterval, clearTimeout, clearInterval for iOS6.
// iOS6 suffers from a bug that kills timers that are created while a page is scrolling.
// This library fixes that problem by recreating timers after scrolling finishes (with interval correction).
// This code is free to use by anyone (MIT, blabla).

JavaScript Multiton Example
/*
Use, reuse but don't abuse!
Author: Razvan Caliman (razvan.caliman@gmail.com)
This is an example of a "Multiton" pattern;
Create a fixed number of instances of a class.
Use "lazy instantiation" to create objects only if needed.
If the maximum number of instances has been reached, return a random one from the ones created.
