bs_calctype = 3 is not coded (not difficult but I really don't have time now)

bs_calctype = 2 is coded by it's not, let's say, very user-friendly.
One has to provide a file __in.gw__ with the GW corrections produced a previous GW calculation.
The BSE code will read the new energies from this file.

1 ) Running bs_calctype = 2 always gives this error :
Complex energies are not supported yet!
So this is practically not implemented.
2 )
bs_calctype = 3 is not coded (not difficult but I really don't have time now)

The most interesting bs calculation type is unfortunately not implemented. Hopefully this will be available in near future.
