[Wien] optimize for cubic materials

[Natalie Holzwarth]

I happened to run the optimize program for a simple bcc material and
noticed that the structure files were created with lattice constants
scaled by [(percent)*(#atoms in cubic cell)]^(1/3).  One way to fix this
is if a=b=c, scale the lattice constants by (percent)^(1/3) or perhaps
just print out a warning to check the case.struct files by hand???  Of
course, this is not a very big problem.   Thanks, NAWH
