The PropPlane constructor calls the SimpleProjectile constructor to initialize the initial
location and velocity of the airplane. It then assigns values to the fields declared in the class
based on arguments passed to the constructor. Initially, the bank angle, angle of attack, throttle
setting, and flap deflection are all set to zero.
