Example program testing for new state update for rkck dot state:

program test

                      [1,1,1,1,1,1,1,1,1,1,&
                       2,2,2,2,2,2,2,2,2,2,&
                       3,3,3,3,3,3,3,3,3,3,&
                       4,4,4,4,4,4,4,4,4,4,&
                       5,5,5,5,5,5,5,5,5,5,&
                       6,6,6,6,6,6,6,6,6,6],[6,10])

real, dimension(10) :: residuum

integer :: i

residuum = B(1)*dotState(1,:)+& 
           B(2)*dotState(2,:)+& 
           B(3)*dotState(3,:)+& 
           B(4)*dotState(4,:)+& 
           B(5)*dotState(5,:)+& 
           B(6)*dotState(6,:)
do i =1,10
  print*,residuum(i)
enddo

residuum =  matmul(transpose(dotState),B)

Pratheek Shanthraj bbb5ff6ae9 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
