Simple API

Subclass Extendable to create your first class.

var Car = Extendable.extend(function(options) {
  // ... constructor
}).shared({
  // ... prototype members
}).statics({
  // ... static members
});

Which itself can be subclassed.

var Audi = Car.extend( /* ... */ );
var Toyota = Car.extend( /* ... */ );

And whose subclasses can also be subclassed.

var AudiHatchback = Audi.extend( /* ... */ );
var ToyotaHatchback = Toyota.extend( /* ... */ );
