/**
 * Add the jamon features to your application.
 * 
 * The feature and it's components require a data provider for monitoring data. This can be done by
 * registering a {@link MonitoringRepository} to the application meta data.
 * 
 * Optionally if you want to use the component monitoring provided, another
 * {@link IRequestCycleListener} is required.
 * 
 * To include this {@link IInitializer} in your application you need to register it by
 * {@link ServiceLoader}. So it is required to add a file called 'org.apache.wicket.IInitializer' to
 * folder 'META-INF/services'. File content needs to be the fully qualified classname of this
 * {@link IInitializer}
