Could use some help implementing this

[eluser]Unknown[/eluser]
I'm working on a project that deals with user submitted urls and I need to break them apart. I found this repository on git that does exactly what I need it to do

https://github.com/jeremykendall/php-domain-parser

but I'm a little lost on how to use it within CI. I've got it working just fine on a stand alone page, but really unsure of how to bring it into CI. Everything I've tried has just given me include errors/file not found errors etc.

Tried loading it as a library, helper and just regular old php require. Can anyone point me in the right direction?

Thanks
