2 // *** Class AliRsnMonitorFunctions ***
4 // "Core" method for defining the work on a pari of particles.
5 // For one analysis, one must setup one of this for each pair he wants to analyze,
6 // adding to it all analysis which he desires to do.
7 // Here he defines the cuts, and the particle types and charges, and can add
8 // functions which do different operations on the same pair, and some binning
9 // with respect to some kinematic variables (eta, momentum)
