<static> {Object} glow.util.apply(destination, source)

Copies properties from one object to another All properties from 'source' will be copied onto 'destination', potentially overwriting existing properties on 'destination'. Properties from 'source's prototype chain will not be copied.

Returns:: {Object} The destination object.

<static> glow.util.extend(sub, base, additionalProperties)

Copies the prototype of one object to another The 'subclass' can also access the 'base class' via subclass.base

			function MyClass(arg) {
				this.prop = arg;
			}
			MyClass.prototype.showProp = function() {
				alert(this.prop);
			};
			function MyOtherClass(arg) {
				//call the base class's constructor
				arguments.callee.base.apply(this, arguments);
			}
			glow.util.extend(MyOtherClass, MyClass, {
				setProp: function(newProp) {
					this.prop = newProp;
				}
			});

			var test = new MyOtherClass("hello");
			test.showProp(); // alerts "hello"
			test.setProp("world");
