Time for action — modifying the gameClasses file

To modify the gameClasses file, we will follow the ensuing steps:

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

What just happened?

You have added importing of the bombClass.monkey file so it can be used now.
