Terraforming Mars Board Game Overlay

A remix to fix a few things I didn't like on the original.

• I opened up the lower right corner to make it easier to slide the cubes across.
• I flattened the entire face of it so you can print it face down if you have a textured plate that gives a nice finished look.
• I added grooves in the side so the top and bottom slide together, rather than just sitting inside each other with nothing holding them together.
