// The bulk of the content in this view is driven by a YapDB view/mapping.
// However, we also want to optionally include ReminderView's at the top
// and an "Archived Conversations" button at the bottom. Rather than introduce
// index-offsets into the Mapping calculation, we introduce two pseudo groups
// to add a top and bottom section to the content, and create cells for those
// sections without consulting the YapMapping.
// This is a bit of a hack, but it consolidates the hacks into the Reminder/Archive section
// and allows us to leaves the bulk of the content logic on the happy path.
