Added method AliInputEventHandler::GetStatistics(Option_t *option) to retrieve the physics selection histograms in ESD and AOD analysis.
This method will return the statistics TH2F histograms filled by the AliPhysicsSelection in case the task AliPhysicsSelectionTask is used in the ESD train (or used during AOD production).
To use, the user task must call this method during FinishTaskOutput (executed on the worker after all events are processed):

//________________________________________________________________________
void AliAnalysisTaskPt::FinishTaskOutput()
{
// This gets called at the end of the processing on the worker.
  AliAnalysisManager *am = AliAnalysisManager::GetAnalysisManager();
  AliInputEventHandler *inputH = dynamic_cast<AliInputEventHandler*>(am->GetInputEventHandler());
  if (!inputH) return;
  TH2F *histStat = dynamic_cast<TH2F*>(inputH->GetStatistics());
  TH2F *histBin0 = dynamic_cast<TH2F*>(inputH->GetStatistics("BIN0"));
