/**
* This file includes polyfills needed by Angular and is loaded before the app.
* You can add your own extra polyfills to this file.
*
* This file is divided into 2 sections:
* 1. Browser polyfills. These are applied before loading ZoneJS and are sorted by browsers.
* 2. Application imports. Files imported after ZoneJS that should be loaded before your main
* file.
*
* The current setup is for so-called "evergreen" browsers; the last versions of browsers that
* automatically update themselves. This includes Safari >= 10, Chrome >= 55 (including Opera),
* Edge >= 13 on the desktop, and iOS 10 and Chrome on mobile.
*
* Learn more in https://angular.io/docs/ts/latest/guide/browser-support.html

/**
* INTERNET EXPLORER
*
* All the Internet Explorer polyfills are defined separately, in the `ie-polyfills.js` file.
* They are also built separately from the main app, via the `yarn build-ie-polyfills` task.
* The output of this build is conditionally loaded (only if we are running IE) in the browser,
* and executed before the rest of the application files are executed.
