-- Cannot be in group when not in study population,
-- enters late: update of intervals.

-- Bugs:
--  This only happens to work because the intervals trigger checks
-- departdate before checking other stuff, like whether there
-- is a mom.  The right way is probably to copy an existing follow
-- to another date and to move the group surveys' to it.
--
-- The interval.intid value needs to be filtered out of the pass test.

-- We have all the intervals for follows 1-4, but only the 2nd day
-- of follows (followid 3 and 4) of groups.

-- Change the entrydate of FE2 (young female) so that she is born
-- on the follow date, then switch the intervals to the follow of
-- the day earlier.
