3  * @details <b>Index.php - the main entry point (controller) of the website's frontend</b>
4  *
5  * First of all, the session gets started, error reporting is set, followed by
6  * including all required classes (because its faster than SPLautoload).
7  * Afterwards, a handful of objects will be created:
8  * <ul>
9  * <li>\YAWK\db</li>
10  * <li>\YAWK\template</li>
11  * <li>\YAWK\user</li>
12  * <li>\YAWK\page</li>
13  * <li>\YAWK\controller</li>
14  * <li>\YAWK\stats</li>
15  * </ul>
16  * <p>Those objects are holding all data used by the frontend. Additional
17  * you can use any of that many static methods from other classes. See class
18  * overview for details about how YaWK is organized.</p>
