Initial Code 
//used below in "secret" linking
function object(o){//new function, argument o
	function F() {}//define function F(empty)
	F.prototype = o;//add the custom property/method passed through o
	return new F();//return the new function with the added property/method
}
//Old object
var myObject = {
		name: "Matt",
		dob: "12/12/1913",
		age: "95",
		ocupation: "Web Developer"
}
//Secret link new object to old object
var myNewObject = object(myObject);

//add values to the new object
myNewObject.name = "new name";
myNewObject.crime = "crime";

//it can't find "age" in new object, it looks at the old object via the link.
console.info(myNewObject.crime);//firebug
console.info(myNewObject.age);//firebug

//delete info in an object
delete myObject.ocupation;
console.warn(myObject.ocupation);//firebug

Shows you how to link 2 objects together via the object function. If a value isn't found in the object, it will look for it in the linked object.
