* <p>This is an ordered sequence of timelines, which may or may not

* the room state at the start and the end of the timeline (if appropriate).
* It also tracks forward and backward pagination tokens, as well as containing
* links to the next timeline in the sequence.
*
* <p>There is one special timeline - the 'live' timeline, which represents the
* timeline to which events are being added in real-time as they are received
* from the /sync API. Note that you should not retain references to this
* timeline - even if it is the current timeline right now, it may not remain
* so if the server gives us a timeline gap in /sync.
*
* <p>In order that we can find events from their ids later, we also maintain a

// Adding events to timelines can be quite complicated. The following
// illustrates some of the corner-cases.
//
// Let's say we start by knowing about four timelines. timeline3 and
// timeline4 are neighbours:
//
// timeline1 timeline2 timeline3 timeline4
// [M] [P] [S] <------> [T]
//
// Now we paginate timeline1, and get the following events from the server:
// [M, N, P, R, S, T, U].
//
// 1. First, we ignore event M, since we already know about it.
//
// 2. Next, we append N to timeline 1.
//
// 3. Next, we don't add event P, since we already know about it,
// but we do link together the timelines. We now have:
//
// timeline1 timeline2 timeline3 timeline4
// [M, N] <---> [P] [S] <------> [T]
//
// 4. Now we add event R to timeline2:
//
// timeline1 timeline2 timeline3 timeline4
// [M, N] <---> [P, R] [S] <------> [T]
//
// Note that we have switched the timeline we are working on from
// timeline1 to timeline2.
//
// 5. We ignore event S, but again join the timelines:
//
// timeline1 timeline2 timeline3 timeline4
// [M, N] <---> [P, R] <---> [S] <------> [T]
//
// 6. We ignore event T, and the timelines are already joined, so there
// is nothing to do.
//
// 7. Finally, we add event U to timeline4:
//
// timeline1 timeline2 timeline3 timeline4
// [M, N] <---> [P, R] <---> [S] <------> [T, U]
//
// The important thing to note in the above is what happened when we
// already knew about a given event:
//
// - if it was appropriate, we joined up the timelines (steps 3, 5).
// - in any case, we started adding further events to the timeline which
// contained the event we knew about (steps 3, 5, 6).
//
//
// So much for adding events to the timeline. But what do we want to do
// with the pagination token?
//
// In the case above, we will be given a pagination token which tells us how to
// get events beyond 'U' - in this case, it makes sense to store this
// against timeline4. But what if timeline4 already had 'U' and beyond? in
// that case, our best bet is to throw away the pagination token we were
// given and stick with whatever token timeline4 had previously. In short,
// we want to only store the pagination token if the last event we receive
// is one we didn't previously know about.
//
// We make an exception for this if it turns out that we already knew about
// *all* of the events, and we weren't able to join up any timelines. When
// that happens, it means our existing pagination token is faulty, since it
// is only telling us what we already know. Rather than repeatedly
// paginating with the same token, we might as well use the new pagination
// token in the hope that we eventually work our way out of the mess.
