//
// *** Class AliRsnCutManager ***
//
// This class is used both in normal analysis and efficiency computation
// as a collection of all cuts which could be needed in a single job.
// It allocates an AliRsnCutSet for each possible target:
//  - one with all cuts common to all tracks
//  - one with all cuts for first candidate daughter (definition #1 in pairDef)
//  - one with all cuts for second candidate daughter (definition #2 in pairDef)
//  - one with all cuts on the pair
// -----
// This object is used to define a step in efficiency CORRFW container
// and also is contained in all AliRsnPair objects to decide if two candidates
// can be accepted or not.
