Create Game2048

I was bored one night during the third quarter of my freshman year at CalPoly, so I decided to write the logic and a basic command line display for the popular tile game 2048. It doesn't check to see if the player won or lost, and it sort of turned into a messier, hacked and patched together piece of code, as quick one-night projects are likely to end up, but it's playable. Perfect for looking as though you're doing something productive from the command line, when in fact you're playing a casual game.
