// AliAnalysisStatistics - basic class for storing statistics for the processed
//   events. The object is mergeable and can be used for general purpose. In case
//   a AliAnalysisTaskStat is used, this will set the global statistics object
//   to the analysis manager and will update it for the accepted events.
