For variants, we need at least the following tutorials:

• data generation
  • residue
  • atom
• training
  • classification for GNNs
  • classification for CNNs
  • references to regression
• update readme and docs/ with variants
• update the folder data/ in zenodo (https://zenodo.org/record/7997586), and be careful about uploading the data only and not MAC leftovers (such as DS_Store and similar)
