Logging of any event changes is incredibly useful in debugging complex parallel behaviour.
The Event Log library is based around an Event Log Abstraction class, that defines a standard interface to provide a plug-in for event logs of different capabilities.

Currently there are 2 children class:
Syslog Event - This sends a syslog formatted message to a syslog server.
TextLog Event - This provides a text box that can be used to display the log messages
