Angular Ui Router Needs Polyfill

This problem was Fixed version 1.0.20!! (thanks betty!)

In IE(Internet Explorer) 11, Angular-UI-Router(v1.0.19) with AngularJS and ocLazyLoad failed to instantiate.

SCRIPT5022: [$injector:modulerr] Failed to instantiate module majorApp due to:
Error: [$injector:modulerr] Failed to instantiate module ui.router due to:

To resolve this error, you need polyfill.

Add the below code.

<script src="//cdn.polyfill.io/v2/polyfill.min.js?features=default,MutationObserver"></script>

And it will work.

P.S.

1. This problem was fixed. It works on v1.0.20.
2. If polyfill did not work, use this polyfil from mozilla.org(thanks brennaveen!)
3. v1.0.19 looks unstable
