Add controllers for adding cars and controlling parking spaces

[JoeyBB91]

As the project is the delivered (the as-­is) the simulation is not really easy to expand or maintain. This is why we are working on this simulation to make it easier to add cars, to maintain the amount of cars that are entering the car park and to have a control over the parking spaces, rows, floors and cars.
