HCal collection names
The convention for naming the "EndcapP" for positive and and "EndcapN" for negative (when the distinction needs to be made). "HcalHadronEndcapHits" and "HcalElectronEndcapHits" should be "HcalEndcapPHits" and "HcalEndcapNHits", but is there a reason for the the endcaps to be separate hit collections?
