// File:  Generators/FlowAfterburner/CheckFlow.h
// Description:
//    This is a simple algorithm to histogram particle properties
//    for diagnosing of flow generation
//
//    It has a single important parameter m_rapcut 
//    to cut off particles from very forward pseudorapidity region
//
// AuthorList:
// Andrzej Olszewski: Initial Code February 2006
