Subscribe propagator p with propagation condition pc.
In case schedule is false, the propagator is just subscribed but not scheduled for execution (this must be used when creating subscriptions during propagation).
In case the variable is assigned (that is, assigned is true), the subscribing propagator is scheduled for execution. Otherwise, the propagator subscribes and is scheduled for execution with modification event me provided that pc is different from PC_BOOL_VAL.
