2068 rm showup
We are thinking about replacing the showup mechanism. The current approach has some issues:
- Showup needs to be entered for each appointment individually. This is very fiddly and a bit confusing.
- Participation that are not
INVITED
will be deleted at the end of a study. So all showup information for them is lost.
This MR is about removing all traces of the old mechanism. We probably should first add the new mechanism and migrate the data. That is still to do.
