Detailed Description

author: Sam Harper (inspired by InterestingDetIdProducer)

Make a collection of detids to be kept in a AOD rechit collection These are all the ES DetIds of ES PFClusters associated to all PF clusters within dR of ele/pho/sc The aim is to save enough preshower info in the AOD to remake the PF clusters near an ele/pho/sc
