Towards dropping GaudiAlgorithm
Dropped not needed references to GaudiAlgorithm
Converted TestRecVertexHolder and CheckPV to functional
Dropped a number of unused algorithm :
- PVRelatorAlg
- BestPVAlg
- BestPVAlg2
- FilterEventList @sstahl @graven @erodrigu can you confirm these can go ? Or point me to whoever can confirm ? Note that I've carefully created on commit per file, so we will be able to revert selectively any file I should not have deleted. Only point is that they would have to be modernied
