Subject: Initial setup commit

This setups up the project for messing around with C++ and Lua bindings.
So far this project just prints the defined dng map and lets you move
the character around.
What this fails to do is actually provide any reason to use Lua at the
moment. So I need to figure out some way of enabling logic on the
processing side of things.
