New functionalities: - imported list of molecules from GISSMO - generated 3D PDB files using OpenBabel - imported list of molecules into frontend: it's now possible to generate any molecule available in GISSMO Known issues: - on Windows the repository is breaking git, as the PDB directory contains some duplicates (it works on Linux because Windows is case-insensitive) - the spin matrix is not loaded from the file yet. Functions are in place , needs some tweaking: the J matrix should be retrieved when selecting the molecule in the list, not before. - same as above for the frequency f.
