/**
 * The only purpose of this plugin is to initialize the {@link LoggingPlugin
 * logging support}. This enables fine-tuning the log behaviour by providing a
 * custom <code>log4j.properties</code> file. If the Pivot Model implementation
 * is used outside of Eclipse, this plugin is not needed. The classes in this
 * plugin only refer to the log4j {@link Logger} class, never to the custom
 * Eclipse logging support provided by the <code>LoggingPlugin</code>. Thus,
 * logging behaviour can be retained even outside of Eclipse if the log4j
 * libraries are added to the classpath.
