/**
* PureMVC PHP Class Autoloader
* @author Omar Gonzalez :: omar@almerblank.com

*
* Class auto-loader for use with the PureMVC Port for PHP.
*
* While it's usage is completely optional, usage will reduce
* the amount of require(), require_once(), include() and include_once()
* statements you would need to write.
*
* It also provides the benefit of allowing you to centralize the location of
* your PureMVC framework to just one location.
*
* USAGE:
* 1) Change the paths listed in the $_includePaths array to match your PureMVC PHP install paths.
* 2) Add a require_once() statement to your index or bootstrap PHP file.
* ie., require_once 'path/to/puremvc_autoloader.php';
