Adding the Angular UI Doc

HI

I plug [Angular UI Docs](https://github.com/angular-ui/angular-ui-docs) to generate the output.

To keep things simple, I put back the _modules/utils.js_ file and removed the generation task. 
@ProLoser Do you want to have both of them (https://github.com/angular-ui/ui-utils/issues/1#issuecomment-17588010) ?
