Issue: missing functions in CI_Input

[laurensschuitemaker]

Thanks for this great work.

I have a question. Some functions seem to be missing in the CI_Input file, like 'cookie()'.
Is it possible to add these functions? Or can I override the CI_Input file myself somehow, without editing it in the vendor directory?

Thanks!

That is because there has been no one who has needed the method until now.
You could send PR like #16

These is no special mechanism to override the classes in this package. So I'm not sure it is possible or not.
The most reliable way is to fork this repository and create your own private package.
