Time for action — modifying the gameClasses file

To modify the gameClasses file, follow the ensuing steps:

Open the gameClasses.monkey file.
Add an Import statement for the rocketClass.monkey file.
```
Import launcherClass
Import rocketClass
```
Save the file and close it.

By adding this Import statement, the rocket class can be used to create neat, deadly little missiles.

Remember, to actually fire a rocket, each launcher has some code inside its Update method. So, you need to add some code there.
