prototype methods such as those added with 
addProperty.

Object.setOwnProperty("property", value);

Arguments:
- property: (string) a string of the name of the property to be added/changed
- value: the value the property is to recieve

Returns:
- nothing

Example:
// simple addProperty
getHi = function(){
	return "hi";
};
Object.prototype.addProperty("hi",getHi,null);
// make an object to test with
myObj = {};
trace(myObj.hi); // hi
myObj.hi = 5;
trace(myObj.hi); // hi
// ^ as a result of the added hi property on Object.prototype
myObj.setOwnProperty("hi", 5);
trace(myObj.hi); // 5
// ^ setOwnProperty bipassed the added hi property
