Pending Problems

---

1)  ISSUE1199: Persist hepmc vertex status code into output
                      ==> Should we eliminate Geant4EventReaderHepMC
                      ==> Decision: Geant4EventReaderHepMC will be removed
2) ISSUE1285:  Memory Consumption of Sensitive Detectors
                      ==> Should be handled as illustrated in PR1288. Intrinsic problem of the Geant4VolumeManager;
3) ISSUE1296:  DetectorImp::endDocument() called twice for some geometries?
                      ==> Unsure if it is a problem wrongly configuring multiple xml inputs.
4) ISSUE1297:  Possible to dump all available readout elements?
                     ==> Possibly a copy of unsolved ISSUE580 from Valentin about enumerating all sensitive cells.
5) ISSUE1319: Problem with regexSensitiveDetector and volume IDs
                     ==> Interesting use case for reg-ex sensitive detectors
                             having a VolumeMgr equivalent.
6) ISSUE1320:  Replacing a Handle<Segmentation> which contains a MultiSegmentation with the underlying Segmentation
                     ===> Unclear what he really means
7) ISSUE1322: materialScan on CAD-imported geometry : strange results...
                     ==> looks like Frank's materialScan is broken
                             To be investigated (units ?).

Pending:
7) PR1304:     SurfaceManager: lazily construct surface maps on demand (Leonhard Reichenbach)
8) PR1314:     Cylinder segment surface (Armin Ilg)

Closed issues and fixed problems
