cleaned up some extra css no longer needed, but button disabling isn't working anymore...wut
several things. Wired MainCtrl and alias directly to body tag in index.html. Removed alias declaration in index.js for MainCtrl. Therefore, can wire logout buttons to app.logout() for all logout buttons. Moved var userID and classID to within addvote on student.controller so it wouldn't fire too early.
nav bar styling, injected app.user.name
Merge branch 'feature/stuLogoutButt' into development
