//WARNING: interface is NOT final, please dont use this class for now without clearing it with me
//         as I will change it and possibly break all your code
//
//aim: this object will manage all histograms associated with a particular HLT filter
//     ie histograms for computing efficiency of each filter step, id efficiency of gsf electrons passing trigger etc   
//
//implimentation: 
//
