I read somewhere that the first step in software engineering is to research to make sure there isn't already a solution available. I did that step but not well enough. I just found a Youtube video that someone made two years ago with a Java solution that does the same thing as my module. It's better than my solution since all you have to do is download a jar file and double-click it. No programming required.
At least my node can help people find that and it has been a good learning experience for me.
