/**
* Schedules the protocol at given node for the first execution adding it to the priority queue of
* the event driven simulation. The time of the first execution is determined by a reference point
* in time and {@link #firstDelay}, which defines the delay from the reference point. The
* reference point is the maximum of the current time, and the value of parameter {@value
* peersim.core.Scheduler#PAR_FROM} of the protocol being scheduled. If the calculated time of the
* first execution is not valid according to the schedule of the protocol then no execution is
* scheduled for that protocol.
*
* <p>A final note: for performance reasons, the recommended practice is not to use parameter
* {@value peersim.core.Scheduler#PAR_FROM} in protocols, but to schedule {@link CDScheduler}
* itself for the desired time, whenever possible (e.g., it is not possible if {@link CDScheduler}
* is used as a {@link NodeInitializer}).
