Fitter is a C++ program aimed to fit a chosen theoretical
multi-parameter function through a set of data points.
The method of fitting is chi-square minimization.
Moreover, the robust fitting method can be applied in Fitter.
Fitter was disigned to be used for a small-angle neutron
scattering data analisis.
Respective theoretical models are implemented in it.
Some commonly used models (Gaussian and polynomials) are also
implemented for wider applicability.
