+	//		Collection of easing functions to use beyond the default
+	//		`dojo._defaultEasing` function.
+	//
+	// description:
+	//
+	//		Easing functions are used to manipulate the iteration through
+	//		an `dojo.Animation`s _Line. _Line being the properties of an Animation,
+	//		and the easing function progresses through that Line determing
+	//		how quickly (or slowly) it should go. Or more accurately: modify
+	//		the value of the _Line based on the percentage of animation completed.
+	//
+	//		All functions follow a simple naming convention of "ease type" + "when".
+	//		If the name of the function ends in Out, the easing described appears
+	//		towards the end of the animation. "In" means during the beginning,
+	//		and InOut means both ranges of the Animation will applied, both
+	//		beginning and end.
+	//
+	//		One does not call the easing function directly, it must be passed to
+	//		the `easing` property of an animation.
+	//
+	//	example:
+	//	|	dojo.require("dojo.fx.easing");
+	//	|	var anim = dojo.fadeOut({
+	//	|		node: 'node',
+	//	|		duration: 2000,
+	//	|		//	note there is no ()
+	//	|		easing: dojo.fx.easing.quadIn
+	//	|	}).play();
