Event module holds the event trait that defines characteristics of all domain events.
DomainEvent | DomainEvent is a trait that defines an event relevant to the domain. These are always facts about something
that has already occurred that has domain significance. An event has a time at which the event occurred,
and an id that corresponds to which aggregate id the event corresponds to. The implementor
should also be sure to pass the aggregates version in when they create the event, so that
events can be processed in the correct order.
