/**
* Phaser - TweenManager
*
* The Game has a single instance of the TweenManager through which all Tween objects are created and updated.
* Tweens are hooked into the game clock and pause system, adjusting based on the game state.
* TweenManager is based heavily on tween.js by sole (http://soledadpenades.com).
* I converted it to TypeScript, swapped the callbacks for signals and patched a few issues with regard
* to properties and completion errors. Please see https://github.com/sole/tween.js for a full list of contributors.
