6 * The Event class describes an actual event, as it has happened to a certain subject. Often, the same event occurs
7 * to multiple subjects at the same time. That is why the actual description of the event is factored out into a more
8 * general EventDescription class. Events that also lead to sample(s) should be instantiated as SamplingEvents.
