class AliAnalysisTaskVertexESD: public AliAnalysisTaskSE

 Class AliAnalysisTaskVertexESD
 AliAnalysisTask to extract from ESD the information for the analysis
 of the primary vertex reconstruction efficiency and resolution
 (for MC events) and distributions (for real data). Three vertices:
 - SPD tracklets
 - ITS+TPC tracks
 - TPC-only tracks
