started getting links to the gravitars and user profiles in the newsfeed
looks ok for now
pages look mostly good but need to fix some relationships for feed related things
fixed error b/c didn't check to see if there were any microposts before trying to render them on profile page
tried usuccessfully to add a 'post on user's wall' micropost box
small change to gemfile to try to deploy to heroku
returned gemfile to original configuration
removed indexes from feed helper to get it to run on heroku with minimal users
added some formatting things... waiting on friends model to complete page
