+// When we implement track level parallelism, we will use G4PrimaryTransformer.
+// We will also need to merge hits from several slaves. To do so, we will need
+// the following:
+// - MarshaledHCofThisEvent must also have a private const member:
+//     const G4bool canMergeHits = false;
+//   and a virtual method (not pure)
+//     virtual void insertOrMerge(ExN02TrackerHit *);
+// - Then can create a derived class with constructor:
+//     inline DerivedClassConstructor()
+//       : canMergeHits(true),MarshaledHCofThisEventWithTemplate() {}
+// - And insertOrMerge() should be defined in the derived class
+//   The logic for insertOrMerge() can usually be copied from
+//   (for example) ExN02TrackerSD::ProcessHits
