[Wien] AFM calculations for YBCO6

[Madesis Ioannis(John)]

Mr. Delamora, first of all thank you for your dedication, and thorough 
examination of my problem.

I haven't fully tested your solution, however, there are plenty of AFM 
orderings that I wish to test such as A, G and C type, all of which are 
different combinations of in-plane antiferromagnetism. From first trials 
of your solution, what troubles me is the fact that the 
case_super.struct file does not include any numbers such as Cu1, O3. 
However, I have noticed that some of the atoms have "MULT= 2" or "MULT= 
4" and present additional 1 or 3 positions. So I thought of the 
following:
Keep the 1 x 1 x 1 cell, for the sake of calculations, and split by 
myself the Cu1 atoms from 1 atom of MULT= 4, to 2 groups of MULT= 2, and 
use your solution of naming appropriately each atom. I know that you 
suggested something particular, and thank you, but I need to keep the 
computational cost low. Last, I change the space group to "1". After I 
do what I said, I run an initialization, and a proper space group is 
defined. How is that for a solution?
