@nockertsb I had to rewrite the history on master since the private keys for twitter and facebook were on there. I moved the two commits you made to a new branch and did not make any modifications. I'll do a review and tag you when I'm all through.
I'm assuming you commented b/c it didn't compile? This is needed for the wear project. If you want to get rid of it (I'm not particularly opposed) delete it and the wear project please
