Using $scope instead of self in userController

[jorawarsingh]

need to change

 function selectUser ( user ) {
      self.selected = angular.isNumber(user) ? $scope.users[user] : user;
    }

to

 function selectUser ( user ) {
      self.selected = angular.isNumber(user) ? self.users[user] : user;
    }
