in crystallite_stressAndItsTangent we now update the state first (explicit integration) and then integrate the stress (implicit integration) 

also inside the stress integration, it is now possible to define the frequency of the Jacobian update oin the LpLoop through iJacoLpResiduum. The frequency of the Jacobian update for  the stiffness in the crystallite loop is controlled by the parameter iJacoStiffness. 

also updated the corresponding stuctograms in the documentation
