/* FitLinear wraps gsl_fit_linear from gsl_fit.h.
* All of the parameters mentioned below are returned from the function
* in a *LinearFit.
* From the GSL manual:
* This function computes the best-fit linear regression coefficients
* (Y0,Slope) of the model Y = Y0 + Slope*X for the dataset (x, y), two
* vectors
* of identical length n with strides xstride and ystride. The errors
* on y are assumed unknown so the variance-covariance matrix for the
* parameters (Y0, Slope) is estimated from the scatter of the points
* around the best-fit line and returned via the parameters
* (Cov00, Cov01, Cov11).
* The sum of squares of the residuals from the best-fit line is returned
* in Sumsq.
