temporary; DOS PDOS BAND scripts.

*_nspin1 is for nspin=1, *_nspin2 for nspin=2.
foobar is the extensiton of ctrl files such as si, nio, or something.

------------------
BAND
>job_band_nspin1 foobar (for nspin=1)
>job_band_nspin2 foobar (for nspin=2)


------------------
For given BZ_DOSMAX and BZ_NPTS (use new ctrlgen2.py and read it),
DOS
>job_tdos_nspin1 foobar
>job_tdos_nspin2 foobar
Then we have dos.tot.foobar, which are plotted by gnuplot.


------------------
PDOS
For given BZ_DOSMAX and BZ_NPTS (use new ctrlgen2.py and read it),
>lmf --pdos foobar
>lmfdos --pdos foobar
gives dos.isp*.site*.foobar
These can be plotted by gnuplot.
(We have to make job_pdos_nspin*).
