//********************************************************************************
//
// Description:
// This contains a collection of HLTDQMHists used to measure the efficiency of a
// specified filter. It is resonsible for booking and filling the histograms
// For every hist specified, it books two, one to record the
// total objects passing sample selection passed to the class and then one for those objects
// which then pass the HLT filter
// The class contains a simple selection cuts (mostly intended for kinematic range cuts)
// which are passed to the histograms as they are filled.
// The cuts are passed to the histograms as some histograms will ignore certain cuts
// for example, eff vs Et will ignore any global Et cuts applied
//
// Author : Sam Harper , RAL, May 2017
