New version of constitutive_dislo.f90, where some dangerous spots were reformulated.
...
PROBLEM: [001] in tension does not have a symmetrical change of shape, which is definitely not good at all. I checked my implementation and I really do not see any errors. Could someone check it out? Can it comes from the numerical integration?

I will proceed step by step.
...
constitutive_dislo.f90 contains a modified version of Anxin's dislocation based model. As far as tested it, I consider it now error free. Mechanical twinning is NOT implemented YET.
mattex.mpie file is modified in accordance with the changes in constitutive_dislo.f90
It would be a great help if someone else can check the implementation. I may have overseen something.

In dislo:
...
- model for stacking fault energy computation w.r.t temperature and orientation
- classical thermodynamical approach to twin nucleation (delta_E)
- rename some parameters
In crystallite:
- add msg='ok', even if components in consistent tangent are not re-computed
- allow for pseudo-convergence in the outer-loop (case of slow convergence of dislocation densities)
in mattex:
- add new parameters

OpenMP seems to work now
...
watch out for critical sections
write and matmul statements need to be marked accordingly!!!

New update of constitutive_dislo.f60 considering the changes in mesh.f90 (see map_ElemType)
...
Parameters assignation, hardening matrices and constitutive equations are PROPERLY implemented (tested)
Comparison to my own old subroutine: on going

!!!!! IMPORTANT !!!!!
...
All subroutines were committed at once:
- constitutive_pheno works
- constitutive_dislo without twinning also works
This release should serve as reference
