Replaced original functional-style inheritence with pseudoclassical inheritence used by Google Closure and Backbone.

Removed dependence on XUI or any other 3rd-party code.

+This is basically the inheritance pattern used in Backbone so props to Jeremy Ashkenas and the Google Closure team:
 
-# JavaScript OO
+* Pseudoclassical inheritence (see [this blog post](http://bolinfest.com/javascript/inheritance.php) for pros/cons of this approach).
+* Ability to extend both prototype and Class methods.
+* Ability to override the constructor.
 
-Super lightweight Object Oriented library for JavaScript.
+In addition, this script adds:
 
-## Examples
-
-Create a simple class, with no properties or methods:
-
-    User = Class()
-    // or Class.extend()
-    
-Create a class containing both properties and methods:
-
-    User = Class({
-      type: 'user',
-      init: function(name) {
-        this.name = name
-      }
-    })
-    
-Create an instance of the "User" class above:
-
-    tj = new User('tj')
-    tj.type
-    // => "user"
-    tj.name 
-    // => "tj"
-    
-Subclass the User class we created:
-
-    Admin = User.extend({
-      type: 'admin'
-    })
-
-    tj = new Admin('tj')
-    tj.type
-    // => "admin"
-    tj.name 
-    // => "tj"
-    
-Reference superclass methods using __super__:
-
-    Admin = User.extend({
-      init: function(name, age) {
-        this.__super__(name)
-        this.age = age
-      },
-      
-      toString: function() {
-        return '<Admin name="' + this.name + '" age=' + this.age + '>'
-      }
-    })
-    
-    tj = new Admin('tj', 22)
-    tj.toString()
-    // => "<Admin name=\"tj\" age=22>"
-      
-Include more methods:
-
-    Admin.include({
-      says: function(){
-        return 'Im an admin!'
-      }
-    })
-    
-Or include some mixins (objects):
-
-    Enumerable = { ... }
-    Comparable = { ... }
-
-    Animal = Class({
-      include: [Enumerable, Comparable]
-    })
-    
-Or a single mixin:
-  
-    Animal = Class({
-      include: Enumerable
-    })
-    
-Extend singleton prototype with methods:
-
-    User = Class({
-      extend: {
-        path: '/users'
-      }
-    })
-    
-    User.path
-    // => '/users'
-    
-Or using "mixins":
-
-    User = Class({
-      extend: Foo
-    })
-    
-Or using several "mixins":
-
-    User = Class({
-      extend: [Foo, Bar]
-    })

+* No 3rd-party dependencies.
+* Built in support for calling `initialize` by the constructor.
+* Will automatically extend simple objects, rather than replace them (useful for `options`, etc).
+* Adds __name__ property to methods for introspection (ie for use with a call stack - see specs for usage).
