/* Discrete Event Queue
|
|
* --------------------
|
|
* The NTP simulator is a discrete event simulator.
|
|
*
|
|
* Central to this simulator is an event queue which is a priority queue
|
|
* in which the "priority" is given by the time of arrival of the event.
|
|
*
|
|
* A discrete set of events can happen and are stored in the queue to arrive
|
|
* at a particular time.
