First refactor into SuperFeed - appears to have a working profile feed
Appear to have a working user feed -- still need to address memory problem
user feed update - fixed cache policy
Updated user search so that it doesn't search when there is no text in bar - changed color scheme of search bar - added description in user results
Changed user search segue from programmatic view controller instantiation to storyboard segue -- setting up of the VC is now in prepareForSegue(); still need to fix black bar at bottom
