Class.create([superclass][, methods...]) → Class

• superclass (Class) – The optional superclass to inherit methods from.
• methods (Object) – An object whose properties will be "mixed-in" to the new class. Any number of mixins can be added; later mixins take precedence.

Creates a class.

Class.create returns a function that, when called, will fire its own initialize method.

Class.create accepts two kinds of arguments. If the first argument is a Class, it's treated as the new class's superclass, and all its methods are inherited. Otherwise, any arguments passed are treated as objects, and their methods are copied over as instance methods of the new class. Later arguments take precedence over earlier arguments.

If a subclass overrides an instance method declared in a superclass, the subclass's method can still access the original method. To do so, declare the subclass's method as normal, but insert $super as the first argument. This makes $super available as a method for use within the function.

To extend a class after it has been defined, use Class#addMethods.
