webpack/require-polyfill.js

// Polyfill for node.js
//  - adds require.ensure
//  - adds require.context
//  call it like this: 
//   require = require("webpack/require-polyfill")(require.valueOf());
// This is only required when you want to use the special require.xxx methods
//  in server-side code which should be so only in rar cases.
