 ** @brief QA task class for digi events produced by the event builder
 ** @author Volker Friese <v.friese@gsi.de>
 ** @since 15.03.2022

 ** Currently implemented functionality: histogram the STS digi time within each event.
 ** To be expanded for other detector systems and probably more QA figures.
 ** The histograms are published to the THttpServer.
