ES6 style class system.
Although originally designed for

ES6 style class system.
Provides a class factory with additional functionality, like [`mixins`](#mixins) and [`plugins`](#plugins). Although originally designed for use with [Node.js](http://nodejs.org) and installable via `npm install cla6`,
it can also be used directly in the browser.

## Mixins
Each class created by Cla6 can be extended using a mixin. Mixins can be applied at class creation or during run time.
```js
var mixin1 = {
method1: function() {
console.log('mixin1');
}
};
var mixin2 = {
method2: function() {
console.log('mixin2');
}
};
var mixin3 = {

Klass.mixin(mixin3);
var obj = new Klass(); // klass
obj.method1(); // mixin1
obj.method2(); // mixin2
obj.method3(); // mixin3
```
## Plugins
Plugins can be applied by Cla6 using the following syntax:
A Cla6 plugin is a manupulation function which gets the classe's descriptors anytime before it gets created, thus the properties can be manipulated. Multipile plugins can be applied and will be called by their use order.
Note, each plugin will affect the descriptors object for the next plugin in the plugins chain.
