Subject: [PATCH] feat(editor): the profile takes the switch zones from the
 //$r records: the parts of a double slip and the paths of a crossing make one
 zone from its first part to its last, a crossing made of plain paths is a
 zone too, the zone is named by the number and the type of the switch; a
 switch with no record stays a zone named by its path; self-test vprofile logs
 the zones
