This is the simpleset example: Parse PDOS and PBANDs of Silicon(diamond).

NiteL

(1) The input files of this example is chosen from ABACUS/examples/02(c-d). Extra parameter "out_proj_band" for 
PBANDS calculation is needed in 02c.

(2) It is recommended that one use a script to parse PDOS and PBANDS, or you can do it by `python band.py` and `python dos.py` directly. 

(3) There is a bug when use command-line to parse PBANDS: 
```

I'm still trying to fix this.
