Time for action — creating some launchers in the game

To create launchers follow the ensuing steps:

Open the mainClass.monkey file.
Inside the SetupGame method, add the left launcher by calling CreateLauncher. Its x position is 30 pixels and it has the A key as a trigger and 15 rockets to start with.
```
Next
CreateLauncher(30.0, KEY_A, 15)
```
Add the right launcher using a different x position and S as the trigger key, but also specify that there are 15 rockets.
```
CreateLauncher(cWidth - 30.0, KEY_S, 15)
```

You told the game to create two rocket launchers at the beginning of the game. Easy, isn't it? Creating those classes pays off now.

In each frame, we want to check if one of the trigger keys was hit and then fire a rocket.
