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.

Notify the command that data from VPP has arrived and been stored.
The command should now inform its clients/listeners.

Retire the command.
This is only appropriate for Event Commands As they persist until retired.
