[Wien] Using fold2Bloch for the path perpendicular to G-K

[Oleg Rubel]

Thanks a lot for the format references, Gavin!

The fold.m is now updated to generate case.klist_band file:
https://github.com/rubel75/fold2Bloch-VASP/blob/master/utils/fold.m

The sample case.klist_band file is attached. I used MATLAB format
'%10i %9i %9i %9i %9i %4.2f'
This should be compatible with the FORTRAN FORMAT(A10,4I10,3F5.2,A3) 
with spaces between integers to improve readability to a human eye.

The code checks for the integers to fit into the format %9i to avoid 
'******' type of output. It is better than xcrysden in this respect :)
However, presently it generates an error, if the integer exceeds the 
format size, but does not fix the problem.

Best regards
Oleg
