Title: MergeSimSources Utility Class Author: Wes Ketchum (wketc.nosp@m.hum@.nosp@m.lanl..nosp@m.gov)

Description: Class that merges different simulation sources together to created a combined sim list. Typically just merges vectors/maps/etc together. But, if anything as a G4 trackID, applies a user-defined offset to those IDs.
