How to use namespace with CI?

Codeigniter doesn't use namespaces and, as far as I'm aware, there's not any plans to add namespaces yet.

The main structure of the framework doesn't support namespaces without a major re-write (As far as I can see from the way the framework is structured). However, that said, it is an open source, community driven framework so, if you want to incorporate namespaces fork it on github or bitbucket and give it a go.
