Added github commits example.

Hey All, @glennblock, @shakeelmohamed, @madhadron, @davidfstr,

Today is my last day but I would like to finish this example sometime soon.

If you guys would like to write your comments here, I'll update the example and then let you guys release it.

Thanks for all the help!
