//
//   description: Definition of the producer for the HCAL noise information.
//                Uses various algorithms to process digis, rechits, and calotowers
//                and produce a vector of HcalNoiseRBXs.
//                To minimize the time used to sort the data into HPD/RBX space, we fill
//                an rbxarray of size 72, and then pick which rbxs are interesting at
//                the end.
