Made some changes to awsservice
Fixed conflicts
bugfix: added a cursor to css on pagination
Tweaks: removed saved papers dropdown
Finished functionality of adding and removing likes and dislikes
Trimmed some of the if/else statement. Still works
Removed commented out code
Grammar errors
Tweaks: Some space fixes
 Made a mistake trimming some of the fat so I replaced the fat. It's a little trickier than I thought.
Commit
Still messing with likes.
sorted topic names and paper lists
Recommendation now working even on second try.
Fixed multiple main ctrl (sorta)
Removed ng-controller and added ending tag for container. There is now a headercrtl for signin.
Adding the ending tag also makes the spacing and stuff nicer on the view (lines up with search box gray thing).
Need to pass the search to the search ctrl since it is no longer nested in mainctrl.
Added stuff for like persistence
Searching: Search now done through url parameters.
Search is done using $location. Enter is now accepted as well as pressing the button for searching.
This inadvertently fixes the back button bug. See issue #24 for more info on that.
Added some more like stuff. Still not done.
Deployment ready.
script names are all lower case now (S3 can't do not exact matches).
