Problem: In this exercise, you will build a simple flight simulator using alice 2.2. You will start with a water world, add a seaplane to the world, build events to allow the user to control the plane, and then add other objects to the world to make it look more interesting. You will create the following keyboard controls for the seaplane

- turn the plane forward (nose down)
- turn the plane backward (nose up)
- turn left
- turn right

You will also modify world.my first method to keep the plane in motion with its propeller spinning, and create an event to activate this method while the world is playing. When you are finished, you will have a world that functions as a simple flight simulator, and that you can further develop on your own into a more so-phisticated flight simulator or game.
