Detailed Description

This histogram class fills a TProfile with the resolution evaluated from the resolution functions for single muon quantities. The resolution functions are used by MuScleFit to evaluate the mass resolution, which is the value seen by minuit and through it, corrections are evaluated.
In the end we will compare the histograms filled by this class (from the resolution function, reflecting the parameters changes done by minuit) with those filled comparing recoMuons with genMuons (the real resolutions).
