Hi,
this is my first pull request, i hope i am not doing anything wrong. I do not know if you are interested but
I have tried to implement the dynamical dark energy model presented in https://arxiv.org/abs/0805.1713

w(z) = w_0 + w_a * (z*(1+z))/(1+z^2)

The values of *w_fld , *dw_over_da_fld and *integral_fld were calculated with the help of Mathematica, i think/hope they are correct.
immagine
I also have accidentally removed a file from the output folder (explanatory00_parameters.ini) and this modification should not be part of the request, but i don't know if it's an issue or you can discard that particular change
