- automatically parse categories from entries
- tried to create feed categories from this info but it didn't work
  for some reason, so i prevented that part of the code from running
-- more fixing of layout styles
-- things looking better, no real problems with layout (nothing overlaps,
   becomes out of grid, etc)
-- added form for new form onto the action links
-- added new feed form and instructions to home page
added subscribe button to feed show pages - it works, too
-- home page now lists all feeds (not just subscribed feeds)
-- sidebar shows only subscribed feeds
-- subscription button next to each feed on the main index (all feeds)
   functions, shows error if already subscribed and success alert
   otherwise.
-- layout more consistent - top bar on all pages with form to add
   a new feed, logout button, and other info / link(s)
-- smoother process of adding feeds
-- loading alert now comes up
-- error for blank url or success alert
-- item show page now shows up when item link is clicked
-- preparing to add nokigiri parsing to get item content
-- ruby readability gem does an OK job of parsing out text
   of articles
-- article show page now shows that content
-- improve style on article show page a little
-- fix problem where feed article previews wouldn't load on feeds'
   show pages (the problem was using getOrFetch instead of
   placing _swapView inside a fetch success callback on a Model)
fixed logout button (was missing closing tag)
got rid of bug where sidebar was duplicating & stacking
functional unsubscribe button. does not say unsubscribe or change page state until reload, but still cool
unsubscribe button now says unsubscribe if unsubscribed
button doesn't really work - branching
