The object tree depth on the console is insufficient for some uses.
Need to be able to specify layout options for the message via the util's formatWithOptions parameter InspectOptions

log4js/lib/layouts.js: 165

  function formatMessage(loggingEvent) {
    return util.formatWithOptions({colors: true, depth: 3, compact: true, breakLength: 80, showHidden: true}, ...loggingEvent.data);
  }
