Detailed Description

Class to store the results from the fit into an ntuple.

Class to store the results from the fit into an ntuple. The fitted values and their errors are stored. In the case of toy MC, the true values are also stored, along with the pulls. Derived quantities can also be stored, such as the fit fractions. What precisely is stored depends on the fit model.
