Added Autoloader+Router

For every class you create, for every method you add, fix or update - respective phpdoc should be created. For methods it should define input params and returned values, for classes it's only a class author (if nothing else should be added). Even class attributes (private, protected or public) should contain respective phpdoc - it's a good habit which helps everyone to read the code and also, as many IDEs read it too - helps you write the code more effectively.
