[Wien] struct2cif for diamond lattice

[Peter Blaha]

I can confirm the problem. It will happen to all structures with 
non-primitive translations in the symmetry operations which cannot be 
written as 1/n.

Seems to be a logical but in SRC_pairhess/struct2cif.f.

In subroutine tau2xyz.f   it was assumed that non-primitive translations 
of a symmetry operation are 1/2, 1/3, 1/4,...
but 3/4 was not supported.

copy the attached tau2xyz.f into SRC_pairhess and recompile.
