By using minfx, and the reported Jacobian, it is now possible to get the exact same error estimation as scipy.optimize.leastsq.

The fatal error was to set the weighting matrix with diagonal elements as the error.
There weights are 1/errors**2.

There is though some un-answered questions left.

The Jacobian used, is the direct derivative of the function.

It is not the chi2 derivative Jacobian.

Fixed naming of functions, to better represent what they do in module of estimating R2eff.

Implemented the Jacobian of exponential function in Python Code.

This now also gets the same error as leastsq and C code.

Fixes for the relax_disp.r2eff_estimate user function documentation.

This is to allow the relax manual to compile again as the original documentation was causing LaTeX
failures.
