  instead of loop of string concatenations.
• Also use Array.prototype.map, and object spread instead of an explicit for loop
• changed: updated the sample output in example/default-metrics.js
• summary metrics now has a pruneAgedBuckets config parameter
  to remove entries without any new values in the last maxAgeSeconds.
  Default is false (old behavior)
