changes related to intermediate configuration kinematics:
...
- switched Fi and Li from state variables to crystallite variables
- Lp and Li are now work conjugate with the corresponding mandel stresses defined in their respective configuration
- T, Lp and Li need to return tangents wrt Fi arising from the convection of the material frame due to Fi
- Updated analytic jacobian to take into account tangents wrt Fi
- Updated Lp and Li residual jacobians to take into account tangents wrt Fi
