## Background
_Note the ES6 module specification is still in draft, and subject to change._
The new ES6 module specification defines a module system in JavaScript using `import` and `export` syntax. For dynamically loading modules, a dynamic module loader factory is also included in the specification (`new Loader`).
A separate browser specification defines a dynamic ES6 module loader loader for the browser, `window.System`, as well as a `<script type="module">` tag for using modules.
This polyfill implements the `Loader` and `Module` globals, exactly as specified in the [2013-12-02 ES6 Module Specification Draft](https://github.com/jorendorff/js-loaders/blob/e60d3651/specs/es6-modules-2013-12-02.pdf) and the `System` browser loader exactly as suggested in the [sample implementation](https://github.com/jorendorff/js-loaders/blob/964623c75d/browser-loader.js).
