Details:
The Chi2 value returned from C-code Curve-fitting return 0.0 for wrong
parameters.
This is expected to influence Monte-Carlo simulations, where minfx can take a
wrong step.
This is inserted as systemtest:
relax -s Relax_disp.test_finite_value -d
R = - 500.
I0 = 1000.
params = [R, I0]
chi2 = func(params)
=> Returns 0.0
This shows, that restraints should be set on, for keeping control over steps
not been taking wrong.
