MooTools TrackInstances Class Mutator

=====================================

Creates an **instances** array property for a class, to contain all of its instances. The array can be used to alter all instances at once, for example -

* A widget class that its instances need to be repositioned upon a window resize

* Stop all music players at once

* Hide all instances of a popup class at once

How to use

----------

Just add **TrackInstances:true** to your class definition, **after** the initialize method.

	var MyClass=new Class({

		initialize:function () {

		},

		TrackInstances:true,

		recalcPosition:function () {

			// something that recalculates position or any other task that should be applied on an instance

		}

	});

	var x=new MyClass();

	var y=new MyClass();

	MyClass.instances; // [x, y]

	MyClass.instances.length; // 2

	// from another code:

	window.addEvent("resize",function () {

		MyClass.instances.each(function (instance) {

			instance.recalcPosition();

		});

	});
