The TimerGroup class is used to group together related timers into a single report that is printed when the TimerGroup is destroyed.
It is illegal to destroy a TimerGroup object before all of the Timers in it are gone. A TimerGroup can be specified for a newly created timer in its constructor.

Clear out all timers.
This is mostly used to disable automatic printing on shutdown, when timers have already been printed explicitly using printAll
or printJSONValues
.
