Since events don't always start on time and rarly end on time, there should be an easier way to update all closures:

A. After defining the dates & times of an event, all closures will inharit it name and times. This will save most of the work handling a large event.
B. Closures who are part of an event will not get deleted when their time is up, but will stay "inactive" for at least a week.
C. Updating the times of an event will update the times of all closures who's time had been inharited from it (e.g. have NULL times and not
have specific times).
