Martin Diehl 64e86666c6 also set initial det(Fp)=0
Marc element lib test failed otherwise for type 117

Martin Diehl 0f70a19266 Fp matters, not Fp^-1
mathematically absolutely equivalent, but numerically not. Sometikes makes a
huge difference in convergence behavior, even though abs(det(Fp)-1) is
in the order of 1e-15

Martin Diehl b861ad11c1 tiny differences between orientation conversions result in more
iterations

Seen so far only for plasticityDetectChanges test (confirmed for dislotwin and
phenopowerlaw).
The max difference between the entries of the rotation matrix from
orientation0%asMatrix() and eu2om(Eulers)/eu2om(orientation0%asEulers) is
1e-15. This is the ratio of km/atom radius! Still, the number of
iterations is consistently higher.
Results are the same. I believe this is a strange coincidence where one
particular orientation causes problems. The current version recovers almost the 'good' behavior
of math_EulerToR(Eulers)

Martin Diehl 77011a5dba this fix restores the previous behavior of dislotwin
very strange behavior in plasticity_detect changes for dislotwin. This
fix restores the old behavior with respect to number of iterations.
Using orientation%fromMatrix() results in much more iterations and an
increase in runtime for the test from approx 6 min to 40 min. Results
still match in the end. Also, crystallite_Fp0 differs by approx 1e-15
only between the two methods.
I assume that something is wrong with either dislotwin or the
state/stress integration
