google index api integration

You are loading it incorrectly:
https://github.com/googleapis/google-api...he-release

Personally I would go with the composer package:
https://github.com/googleapis/google-api...t#composer

As CI 3.x supports it and you don't need to make a CI3 library. You should however make a library that generates all the data and just pass it to your controller so you can display it.
