Update GIT ReadMe to include a brief summary of the project, how to contribute (need to be CFT member?), and directing them to the wiki for more information.

So I needlessly added about 7 commits to the master while trying to find a good template to use for our readme. I don't have a lot of time today, but I am going to try to finish this up on a separate branch, and then do a pull so you guys can chime in on the look of it (like I was suppose to do anyway).

Here is the template I chose.
