phpBB login: Authenticate users registered in a phpBB database

This class is meant to provide user authentication to sites that have already installed the phpBB forum application database.

This class avoids the need to create or install another authentication system if you already have installed or plan to install phpBB.

For now, this class supports only user authetication but not to add, update or delete user records. These features are planned to be supported in future versions of this class.
