updated assignment 3

I honestly just wanted to play around with a random block pattern and experiment with different colors for this project. I kept it fairly simple because I was having trouble understanding the script process. In the beginning, I couldn't figure out how to create a block and automate it, but after looking at another classmate's project, I realized that you had to make the block through pen trails first and then stamp it through script. I was overthinking the process a lot, but once I figured it out, I found it a lot simpler in creating organized code. For the revisions, I went back and simplified my code even more to make it easier to read and more versatile.
