Calculate eigenstates

Calculation of multiband k.p states

The calculation of the eigenstates is controlled centrally by the sub program 'calculate_eigenstates'. This in turn calls for k.p regions the routine 'update_kp'. 'update_kp' is the superior program for the k.p problem.
First the eigenstates for k_||=0 are determined. This occurs by calling 'setup_kp_mat' (setup_kp_mat1D) (setup of the matrix) and then calling 'calculate_kp_eigenvalues' (calculation of eigenstates).
In 'get_range_k' it is decided up to which maximum value of k_|| the Brillouin zone has to be discretized. Then the values for k_|| are being determined ('get_k_par2D' (1D)) and finally the eigenstates for these are determined again.
