//
// Class AliRsnAnalysisManager
//
// This is the uppermost level of analysis objects collection.
// It contains a list of pair managers, which all will process
// a pool of events passed to this object, and fill their histograms.
//
// The utility of this object is to define a unique implementation
// of the whole processing, which can then be included in the different
// designs of AnalysisTask provided for SE and ME analysis.
//
// The base architecture is still AliRsnVManager, but in this case
// all the objects in the list will be AliRsnPairManager's.
