classFollowedConstraint
final class FollowedConstraintOne constraint being followed out from a parent, and what to say of it.
Following a key needs the constraint itself, the table that holds it, and the statement being simulated: the first two say what to do, and all three say what to tell the caller when the action forbids the statement. They travel together for the whole of one cascade, so they are one thing.
