Edit feature

@heyjinkim I fixed the favorite feature and it now works. In <b>checkin-status.hbs</b>, I set currentUser(in favorite-log)=currentUser(checkin-status) and in <b>pairing.hbs</b> I added several new properties, and bound the store to currentUser. Of course, learning about components inside of components and how data is passed from components is incredibly simple and obviously took me all of 5 minutes to do #obviouslykidding :disappointed:  
(but Ember is truly fun to work with and I absolutely love the thorough and comprehensive guides http://emberjs.com/guides/components/passing-properties-to-a-component/)
