Lab 2.2 Yellow Brick Road alternate solution

I found the given solution to lab 2.2 a bit hard to understand. I refactored it to this which I think might be easier to understand.

Keep in mind that this and the given solution do not solve the problem. Both draw extra bricks.

I like to come back to the Yellow Brick Road in lesson 3.2 to show it with loops, conditionals, and a splash of generalization. https://snap.berkeley.edu/snap/snap.html#present:Username=jdonwells&ProjectName=Lab%202.2%20Yellow%20Brick%20Road%20generalized%20with%20conditionals
When demonstrating this you can change the stage size. (must be a multiple of 20 in both directions.) If it doesn't run correctly go out of full screen then press stop sign and green flag a few times. Don't you just love Snap!?
