* Each EventId identifies a unique event scheduled with one
* of the many Simulator::Schedule methods. This EventId can
* be used to Cancel or Remove events after they are scheduled
* with Simulator::Cancel or Simulator::Remove.
*
* The important thing to remember about this class is that
* every variable of this type is _always_ in a valid state,
* even when it has not been assigned an EventId coming from a Schedule
* method: calling Cancel, IsRunning, IsExpired or passing around
* instances of this object will not result in crashes or memory leaks.
