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

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
