 * WORK IN PROGRESS
 * 
 * Intention of this class is to abstract away almost any log facility out there clients might be using with the <b>Hg4J</b> library, 
 * not to be a full-fledged logging facility of its own.
 * 
 * Implementations may wrap platform- or application-specific loggers, e.g. {@link java.util.logging.Logger} or 
 * <code>org.eclipse.core.runtime.ILog</code>
