/**
 * A <code>LogReferenceExtension</code> for saving a reference to another object. Use in
 * that way e.g.: <code>LOG.warn(object)</code>. 
 * 
 * <p> To write your own extension, the following requirements has to be fulfilled: 
 * 1. The customized class must extend the <code>LogEntry</code> class.
 * 2. A table in the database must be created. 
 * 3. The castor mapping file must be customized for the new class. As base the existing
 *    one can be used.
