/**
 * 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.
