Adding routing as a dependency.
Update front controller to use the Routing component. Updated comments
Fork of the index.php front controller. This version uses the HTTPKernel ControllerResolver to resolve the controller and the arguments that it should use.
New controller for studygroup02. This controller builds up on what we did on the fist version but instead of accepting the translation from the input, it accepts a language code and uses a translation array to figure out the proper translation for "Hello World". The controller also takes advantage of the session and stores the user language preference. Next time the user visits the site it will remember the language without having to set one.
Adding new routing file. New routes should be added to this file.
