GameObject

All Known Subinterfaces:

Shooter

All Known Implementing Classes:

AbstractEnemyShip, AbstractGameObject, AbstractShip, Bullet, FollowerEnemyShip, PlayerShip, ShooterEnemyShip
```
public interface GameObject
```
This interface defines many of any game object methods. It's an interface first and not an abstract class so we can create subinterfaces with different functions like Shooter. So if an object is references as Shooter it would still have access to these methods.
