Among other things :
- Dropped unused VPTrackingInfo
- Merged VPGeometry into the VPDetectorElement
- Improved the VP DetectorElement interface to not expose the internals
- Allow functional algorithms using conditions to have non default base class
One can expect tiny changes to the test outputs, but there should be not changes in the counters or histograms.
