// Quality Assurance Object//_________________________________________________________________________
// Quality Assurance object. The QA status is held in one word per detector,
// each bit corresponds to a different status.
// bit 0-3   : QA raised during simulation      (RAW)
// bit 4-7   : QA raised during simulation      (SIM)
// bit 8-11  : QA raised during reconstruction  (REC)
// bit 12-15 : QA raised during ESD checking    (ESD)
// bit 16-19 : QA raised during analysis        (ANA)
// Each of the 4 bits corresponds to a severity level of increasing importance
// from lower to higher bit (INFO, WARNING, ERROR, FATAL)
