- * An Event command base class.
- * Events are one of the sub-set of command type to VPP.
- * A client performs a one time 'registration/subsription' to VPP for the
- * event in question and then is notified asynchronously when those events
- * occur.
- * The model here then is that the lifetime of the event command represensts
- * the during of the clients subscription. When the command is 'issued' the
- * subscription begins, when it is 'retired' the subscription ends. For the
- * subscription duration the client will be notified as events are recieved.
- * The client can then 'pop' these events from this command object.
