+			UB matrix of single crystal sample using Busing-Levy convention:
+			W. R. Busing and H. A. Levy (1967). Acta Cryst. 22, 457-464. This is 
+                        the multiplication of the orientation_matrix, given above, with the B matrix which 
+                        can be derived from the lattice constants.
