Issue that breaks model fitting on multiple cores figured out.

[Alireza Khorshidi]

Model fitting on multiple cores started breaking at commit 6bfe2a8.

It seems that the issue is that I have changed the name of loss function method from __call__ to f and its prime to fprime at here and here, but have not updated lossfunction at here.

I was wondering how we should pass input arguments of LossFunction class at here to __main__ script at here.

What about input arguments of f and fprime?
