Challenge: Turning car
Make the car turn based on keyboard control.

Add keyboard control

Hint

= function() {
if () {
car.turnLeft();
} else if () {
car.turnRight();
}
};

This program displays a car that starts with a constant velocity. In the challenge, you'll get it to turn using
the keyboard and point towards the angle of movement. For this step, just implement code that will call the
car's currently empty turnLeft and turnRight functions when the left and right arrows are pressed.
