/**
 * RecordOrEditParticipationActivity is different from RecordQuickParticipationActivity in the
 * following ways: 1. RecordOrEditParticipationActivity ALREADY has a participation associated with
 * it (created when reminders are served (in NotificationService)). RecordQuickParticipationActivity
 * does not have a pre-existing participation. It has to create one. 2. Because
 * RecordOrEditParticipationActivity serves an existing participation, it has a date and time
 * associated with it. RecordQuickParticipationActivity does not have a date and time a priori, and
 * must get these from the user.
