	 * The SoundManager is a singleton that allows you to have various ways to control sounds in your project.
	 *
 
	 * The SoundManager can load external or library sounds, pause/mute/stop/control volume for one or more sounds at a time,
	 * fade sounds up or down, and allows additional control to sounds not readily available through the default classes.
	 *
 
	 * This class is dependent on TweenLite (http://www.tweenlite.com) to aid in easily fading the volume of the sound.

	 * @author Ryan Christensen (http://drawlogic.com)
	 * @version 1.1 - added Tweener support and removed TweenLite support
