Create a DFT example for FDBM testing from different codes

[ondrejkrejci]

• Set the simple example - @ondrejkrejci
• Calculate in VASP - @ondrejkrejci
• convert CHGCAR and LOCPOT to xsf with v2xsf (standard for PPAFM) - @ondrejkrejci
• Calculate with FHI-aims - @ondrejkrejci
• Calculate with CP2K - @yakutovicha

I have used the same example, as we have in BrClPyridine_FDBM example

The v2xsf used for VASP conversion is from: here

The files are now temporarily at google drive (see only version)
