/**
 * UniversalClassLoader implements a "universal" autoloader for PHP 5.3.
 *
 * It is able to load classes that use either:
 *
 *  * The technical interoperability standards for PHP 5.3 namespaces and
 *    class names (https://github.com/php-fig/fig-standards/blob/master/accepted/PSR-0.md);
 *
 *  * The PEAR naming convention for classes (http://pear.php.net/).
 *
 * Classes from a sub-namespace or a sub-hierarchy of PEAR classes can be
 * looked for in a list of locations to ease the vendoring of a sub-set of
 * classes for large projects.
 *
 * Example usage:
 *
 *     $loader = new UniversalClassLoader();
 *
 *     // register classes with namespaces
 *     $loader->registerNamespaces(array(
 *         'Symfony\Component' => __DIR__.'/component',
 *         'Symfony'           => __DIR__.'/framework',
 *         'Sensio'            => array(__DIR__.'/src', __DIR__.'/vendor'),
 *     ));
 *
 *     // register a library using the PEAR naming convention
 *     $loader->registerPrefixes(array(
 *         'Swift_' => __DIR__.'/Swift',
 *     ));
 *
 *
 *     // to enable searching the include path (e.g. for PEAR packages)
 *     $loader->useIncludePath(true);
 *
 *     // activate the autoloader
 *     $loader->register();
 *
 * In this example, if you try to use a class in the Symfony\Component
 * namespace or one of its children (Symfony\Component\Console for instance),
 * the autoloader will first look for the class under the component/
 * directory, and it will then fallback to the framework/ directory if not
 * found before giving up.
