constraint ->initialise: from=object, to=object, relation=relation, propagate=[{forwards,backwards}]

Create a constraint object from both objects to be constrained (constraint<-from and constraint<-to), the constraint<-relation describing the constraint and optionally whether the constraint should propagate changes in both or only one direction. By default a constraint propagates changes either way. With propagate equals forwards only changes to constraint<-from are propagated to constraint<-to and with propagate equals backwards the other way around.
