/**
 * route.php
 * Routing for PHP built-in web server
 *
 * Example (windows):
 * php -c "C:\PHP_INSTALL_DIR\php.ini" -S localhost:8000 "C:\PATH_OF_WEBMVCFRAMEWORK\route.php" -t "C:\PATH_OF_WEBMVCFRAMEWORK"
 * (for Linux or Mac replace path)
 *
 * Usage example of route.php is inside mvc_bootstrap.bat batch script
 *
 * This file implements HTTP routing when using PHP built in web server instead of Apache HTTP server.
 * It can detect both application or content centric HTTP request.
 * 1) When application centric:
 *      It provides the autoloading features of classes and the MVC objects creations, by using
 *      framework\Loader and framework\Dispatcher classes (depending on the requested URL).
 * 2) When content centric:
 *      Just serve the content of requested resource (or execute a standard php file)
