/**
* Debug logging during a client request.
* So you can measure any action find bottlenecks in your code.
*
* @author hahn
* Source: https://github.com/axelhahn/ahlogger
*
* USAGE:
* (1) Trigger a message with add() to add a marker
* (2) The render() method lists all items in a table with time since start
* and the delta to the last message.
