This function allows us to determine which ids are directly descended from which other ones. It is the only part of the code that relies on the ID format used by the Curitiba study (see Details); by modifying this function, it should be possible to adapt this code to another study.
is.child.ct(id, seed.id)
TRUE if id
is the direct descendant of seed.id
and FALSE otherwise
the id of the potential child
the id of the potential parent
