Class.extend
============
Backbone like `.extend` inheritance helper for Node.js
Usage
------------
You basically got two options:
``` javascript
// 1. Extend from the blank class
const Base = require('class-extend');
const Sub = Base.extend();
// 2. Add the .extend helper to a class
MyClass.extend = require('class-extend').extend;
```
#### `.extend()`
`.extend` allow you to assign prototype and static methods.
If no `constructor` method is assigned, the parent constructor method will be called by default.
``` javascript
// Extend a class
const Sub = Parent.extend({
// Overwrite the default constructor
constructor() {},
// Sub class prototypes methods
hello() { console.log('hello'); }
}, {
// Constructor static methods
hey() { console.log('hey'); }
});
Sub.hey();
// LOG: hey
const instance = new Sub();
instance.hello();
// LOG: hello
```
#### `.__super__`
Sub classes are assigned a `__super__` static property pointing to their parent prototype.
``` javascript
const Sub = Parent.extend();
assert(Sub.__super__ === Parent.prototype);
```
