// Events are emitted by peers at a variety of points during the simulation.
// Each event is emitted by a particular peer at a particular time. Collectors
// process these events, perhaps calculating statistics or storing events to
// a log for post-processing.
//
// The Event types can be arbitrary, but should be copyable and lightweight.
//
// Example collectors can be found in collectors.h, but have the general
// interface:
//
// @code
//     template <class T>
//     struct Collector
//     {
//        template <class Event>
//        void
//        on(peerID who, SimTime when, Event e);
//     };
// @endcode
//
// CollectorRef.f defines a type-erased holder for arbitrary Collectors.  If
// any new events are added, the interface there needs to be updated.
