* Exception autoload method

* <code> throw new AeFooBarBazException('Not found', 404);
* // Will search for the AeFoo_Bar_Baz class
* // inside the ae/classes/foo/bar/baz.class.php file</code>
*
* @see AeAutoload
* @see AeAutoload::extensions()
*
* @param string $class class name
*
* @return bool true if the class file has been successfully found and
* loaded. False otherwise
