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