Detailed Description

Class to provide lumi weighting for analyzers to weight "flat-to-N" MC samples to data.

This class will trivially take two histograms:

1. The generated "flat-to-N" distributions from a given processing
2. A histogram generated from the "estimatePileup" macro here:

This class will trivially take two histograms:

1. The generated "flat-to-N" distributions from a given processing (or any other generated input)
2. A histogram generated from the "estimatePileup" macro here:

https://twiki.cern.ch/twiki/bin/view/CMS/LumiCalc#How_to_use_script_estimatePileup

and produce weights to convert the input distribution (1) to the latter (2).
