Changes made to EventEditor and EventModel classes in order to add in functionality of update choice for the user during event creation.
Merge conflict resolution.
Changes:
- Added automatic refresh functionality to the EventUpdater class, so that
  when an event is updated, the updated event appears for view immediately.

---------------------------------------------------------------------------

CHANGES IN PROGRESS:
- Working on sending the user back to the tab in which they had initially
  triggered the update of a particular event. At the moment a redirect to
  DayView is what occurs.
- Working on incorporating event updating as a selectable option during
  the process of event creation.
