Detailed Description

Implements a fitter for gaussian functions.

This class fits a gaussian distribution to a number of data points. The results as well as the initial guess are specified using the struct GaussFitResult.

The complete gaussian formula with the fitted parameters can be transformed into a gnuplot formula using getGnuplotFormula after fitting.
