//
// General macro to configure the RSN analysis task.
// It calls all configs desired by the user, by means
// of the boolean switches defined in the first lines.
// ---
// Inputs:
//  1) flag to know if running on MC or data
//  2) path where all configs are stored
// ---
// Returns:
//  kTRUE  --> initialization successful
//  kFALSE --> initialization failed (some config gave errors)
//
