Event class:
    An event occurs whenever the state of the system (e.g. the queue length)
    changes. The Event class creates a new event for the Future Event Set.
    Note that the Event class contains a function __lt__. This is a standard
    Python function used to compare objects to another (’lt’ stands for “less
    than”), to determine the order in which they should be sorted.
