/*!
 * Title:   MergeSimSources Utility Class
 * Author:  Wes Ketchum (wketchum@lanl.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.
