Bugfix in _manually_ differentiated form, the automatic Jacobi was the right one!
Also tested a few choices of relaxation parameter,
and omega = 1.0 (no relaxation) easily beats omega != 1.0
in this case.

description:
Implemented demo with Newtons method in Python,
solving the simple nonlinear equation u^3=f.
Discovered a likely bug in the automatic Jacobi
computation, the constants in the generated code differ
from the manually defined form in this case.
