How to change Controllers/Models source dir

[eluser]Mareshal[/eluser]
I need to load controllers and models from a different folder than the default one. I am using a Linux system.

I am building a simple CI application for some people, for use on a shared hosting I own. But I want to give them access only to /views folder and some /config files. And this is why I need to store the controllers and models in a different folder on the same level as /public_html folder or maybe somewhere in the linux system.

I consider this would be a better solution than encoding files
