// *** Configuration script for phi->KK analysis with 2010 runs ***
// 
// A configuration script for RSN package needs to define the followings:
//
// (1) decay tree of each resonance to be studied, which is needed to select
//     true pairs and to assign the right mass to all candidate daughters
// (2) cuts at all levels: single daughters, tracks, events
// (3) output objects: histograms or trees
//
