//
//   description: Container class of RBX information to study anomalous noise in the HCAL.
//                The information for HcalNoiseHPD's are filled in RecoMET/METProducers/HcalNoiseInfoProducer,
//                but the idnumber is managed by DataFormats/METReco/HcalNoiseRBXArray.
//                Essentially contains 4 HcalNoiseHPDs.
