Martin Diehl b6481c2513 introduced simpler multiplication and forall loops 
matmul is ok for openmp, check in the web and run the state integration test.

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

program test

real, dimension(6,10) :: dotState=reshape(&
                      [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
real, dimension(6) :: B=2.5

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)
do i =1,10
  print*,residuum(i)
enddo

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
