[Wien] incorrect DOS

Hi Manish,
I think there is no problem with your DOS of HfO2. The band near -10 eV 
should be the  band corresponding to f-states. Most of published data 
about HfO2 are obtained from pseudo-potential calculations in which 
fully filled f-states are treated as core states. I think this is 
actually a big advantage of all-electron codes like Wien2k in which both 
extended and highly localized states can be treated at the same footing.
