Elevator

• It's an elevator!
• Run the main method in the Game class.

Libraries

• Using Processing (https://processing.org/reference) as the library to help with UI.
• Chose this because it seems more lightweight than other options like libGDX.
• Not using the Processing IDE though. If you want to download the jar on your own (for mac), go to Processing download, download it, right click the download, select Show Package Contents, and find the "core.jar" file in the "Java" folder.
