Convert DFTB parameters in skf format into LATTE's table format
Usage
-----
```bash
DLtab.py <skf folder> <LATTE parameter folder>
```
Three files will be generate for LATTE, electrons.dat, bondints.table and ppots.dftb.
[note for electron.dat file]
* The spin parameter is not included in the skf file, thus, they will be
set to zero, if spin polarized DFTB is needed, don't forget to modify
the electrons.dat file
* The masses defined in skf file is different than the one defined in
changecoord code. Thus, if you need run LATTE-LAMMPS code, don't forget
to modify the masses .
* The script uses Hubbard U for the s shell as U parameter for the
element, which is the same as the default for DFTB+ code.
