Uw devel -Inital Pull Request

We here at the University of Wyoming are intending to develop a "chess" demo for Baxter. Similar to the "connect_four" demo, but implemented in C++ instead of python. I personally, have little experience working with Github, but I believe I have set-up the correct system for doing a "Fork-Pull" contribution style described here: https://help.github.com/articles/using-pull-requests . The chess demo is in its early stages, but I wanted to open to dialogue for merging it with your repository early.
