     * The TraceAllConcern will call the traceEntry(), traceExit() and traceException() methods in the
     * Tracer instance associated with the CompositeType that the TraceAllConcern is part of.
     * <p>
     * The Trace paradigm is all about tracking the entry and exit (both normal and exceptional ones)
     * of methods.

     * <p>
     * The main difference to the <code>TraceConcern</code> is that this concern is not associated with
     * the <code>@Trace</code> annotation, and all methods in the interfaces will be traced, unless
     * the LogService has turned off tracing.
