diff_calc_hkl(), fc_hkl()

diff_calc_hkl( two-theta, omega, chi, phi)
diff_calc_hkl( two-theta, omega, chi, phi, index)

fc_hkl( two-theta, omega, chi, phi)
fc_hkl( two-theta, omega, chi, phi, index) diff_calc_hkl( mu, omega, chi, phi, gamma, delta)

diff_calc_hkl( mu, omega, chi, phi, gamma, delta, index)

Returns the hkl for a given set of angles. index specifies the output: 1 - h, 2 - k, 3 - l, 4 - psi.

If index is omitted, the function returns a string which contains all values.

e.g.:
* = diff_calc_hkl( -1, 46, -97, 126, 1)
