[Wien] How to run init_lapw for supercell?

For sure you have a reason why you want to use a supercell (introducing an
impurity, a vacancy, an interstitial, ...). After 'x supercell' you have to
put e.g. the impurity in the cell (which breaks the symmetry). If not,
sgroup will detect that your supercell contains more atoms than needed, and
will reduce it to the smaller cell again.
