User login

I'm able to login successfully using Rails console and a skip_confirmation! However, my spec is giving me an error : ```Undefined method 'sign_in```

I've reviewed the [Devise ReadMe](https://github.com/plataformatec/devise), and all of the stackoverflow posts including [this one](http://stackoverflow.com/questions/23859653/rails-devise-rspec-undefined-method-sign-in). Can't figure out why this method isn't working for me in the spec. Also unsure why I'm still not able to get email confirmations.
