Creating a Class

var Mammal = require('classical').create(function() {
    this.name                           = null;

    this.constructor = function(name) {
        this.name                       = name;
    };

    this.speak = function(text) {
        console.log('%s says, "%s"', this.name, text);
    };
});

Extension

var Dog = Mammal.extend(function() {
    this.breed                          = null;

    this.constructor = function(name, breed) {
        this.breed                      = breed;
    };

    this.speak = function() {
        this.super.speak('Woof!');
    }
});

Instantiation

var Spot = new Dog('Spot', 'Dalmation');
Spot.speak(); // Outputs: 'Spot says, "Woof!"' to the console.

Interfaces

var Animal = require('classical').interface(function() {
    this.speak                          = function() {};
});
Mammal.implements(Animal);
