Classes to perform curve fitting.
Curve fitting is a special case of a least-squares problem
where the parameters are the coefficients of a function \( f \)
whose graph \( y = f(x) \) should pass through sample points, and
were the objective function is the squared sum of the residuals
\( f(x_i) - y_i \) for observed points \( (x_i, y_i) \).
