/**
* Base class for plugins
*
* A base class for StatusNet plugins. Mostly a light wrapper around
* the Event framework.
*
* Subclasses of Plugin will automatically handle an event if they define
* a method called "onEventName". (Well, OK -- only if they call parent::__construct()
* in their constructors.)
*
* They will also automatically handle the InitializePlugin and CleanupPlugin with the
* initialize() and cleanup() methods, respectively.
