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.

Evaluate the current Gaussian model at the specified points.
Returns the intensities (i.e. probabilities scaled by the factor 'A') of the PDF at the given positions. This function can be called with any set of parameters, e.g. the initial parameters (to get a 'before-fit' status), or after fitting.
