Detailed Description
Handle replies to DRAMA Monitor Messages.
A drama::MessageEventHandler class object is used to handle replies to DRAMA messages.
The MessageEventHandle does not handle trigger messages, it just warns if it gets one. For the DRAMA "MONITOR START" messages we are using to implement monitors, we need to handle the trigger messages, that is how we are told about parameter changes.
This subclass of MonitorMessageHandler overrides the TriggerReceived() method, organizing for appropriate methods in the drama::thread::Monitor class to be invoked. This override is marked as final to avoid a sub-class interfering with the behavior.
Additionally, it overrides the KickReceived() method, which allows monitors implemented by an action to be canceled by kicking the action. A sub-class can override this to change how this is done.
