// Produces an image of a black car with red wheels and a blue window on a grey background. 

/* DEVELOPMENT NOTES:
((Note: this is not something you should include in your own programs; this is included here to aid
         in your understanding and to provide additional context for the program.))
This was our second version of the program to create the image "van2" (which you can find in the 
the Web Comparison Tool) which contains two cars.  To create this output, we created a 
parameterized method that could draw the car at the given location (via x, y coordinate parameters)
