Allow to use unibabel.hex as a ES6 module #1

This PR makes unibabel.hex to be used as a module.
unibabel.hex can be used like: import { Unibabel } from 'unibabel/unibabel.hex.js';

Loo

I'm just seeing this now.

It looks like this breaks browser compatibility.

I think this should fix it, would you mind testing?

-var _index = require('./index.js');
-
-
-
-var Unibabel = _interopRequireWildcard(_index).Unibabel;
-
-
-
-function _interopRequireWildcard(obj) {
-
-  if (obj && obj.__esModule) {
-
-    return obj;
-
-  } else {
-
-    var newObj = {};
-
-    if (obj != null) {
-
-      for (var key in obj) {
-
-        if (Object.prototype.hasOwnProperty.call(obj, key)) newObj[key] = obj[key];
-
-      }
-
-    }
-
-    newObj.default = obj;
-
-    return newObj;
-
-  }
-
-}

To:

var Unibabel = exports.Unibabel || require('./index.js').Unibabel;

It really sucks that there are so many JavaScript-knockoff languages and frameworks that don't maintain compatibility with JavaScript and expect you to break compatibility or add lots of boilerplate to get them to work with The Real McCoy.
