Following discussion on - https://github.com/gonzofish/angular-librarian/issues/56 here is the pr. Let me know what you think?

I'm going to take a look at this tonight.

After an initial look, I think we might need to make the approach more general for scaffolding, but since I don't really know Protractor or its best practices, I may be wrong.

Thanks for the awesome feedback. Again please feel free to decline this pr if you feel it can be improved. I will gladly give it another stab at a future date. I wish i had more time to commit to this 🥇

Thanks for contributing. It's really nice to have people commit time to something you've done. I think the changes are pretty light, so do them when you have a shot, no rush.
