created very basic version of 'top stories' feature

My code is in 'comments.html' (I just realized that file is horribly named because (1) I switched the feature to be top stories NOT comments and (2) it's a JS file, not html....).

It's very basic at this point. Just console logs the top 10 stories for a user. I'll integrate it with angular once we have a front end base laid down.
