Function: $extend
	Copies all the properties from the second object passed in to the first object passed in.
	In myWhatever.extend = $extend, the first parameter will become myWhatever, and the extend function will only need one parameter.

Syntax:
	>$extend(obj1, obj2);

Arguments:
	obj1 - The object to be extended.
	obj2 - The object whose properties will be copied to obj1.

Returns:
	The first object, extended.

Example:
	(start code)
	var firstOb = {
		'name': 'John',
		'lastName': 'Doe'
	};
	var secondOb = {
		'age': '20',
		'sex': 'male',
		'lastName': 'Dorian'

/*
Function: Native
	This will add a .extend method to the objects passed as a parameter,
	but the property passed in will be copied to the object's prototype only if not previously existent.
	The purpose of Native is also to create generics methods (Class Methods) from the prototypes passed in.
	Used in MooTools to automatically implement Array/Function/Number/String/RegExp methods to browsers that don't natively support them.

Arguments:
	Any number of Classes/native JavaScript objects.

Class: Class
	The base Class object of the <http://mootools.net> framework.
	Creates a new Class.  Its initialize method will fire upon class instantiation unless *null* is passed to the Class constructor.

Syntax:
	>var MyClass = new Class(properties);

Arguments:
	properties - (object) The collection of properties that apply to the Class. Also accepts Extends and Implements. See below.
	
Example:

Implements:
	Implements the passed in Class properties into the base Class prototypes. Similar to Extends, but it simply overrides the properties.
	Useful when implementing a Class properties in multiple classes.
