DefineJS: CommonJS/AMD Hybrid Format

##DefineJS v0.2.4 Released

This hybrid CommonJS/AMD format allows to write modules with a new syntax similar to CommonJS. This feature is now possible thanks to the ES6 generators.

Let’s imagine a CommonJS module like:

//app.js
var utils = require('utils'),
  $ = require('../vendor/jquery');

var app = {
  //...
};

module.exports = app;

The DefineJS alternative is:

//app.js
define(function* (exports, module) {
  var utils = yield require('utils'),
    $ = yield require('../vendor/jquery');

  var app = {
    //...
  };

  module.exports = app;
});

As mentioned the new syntax is similar to the CommonJS coding style, with two specific differences. First the yield keyword and the next is the define wrapper with a ES6 function generator.
