add support for analysis and ML models

[helgestein]

My group and I would very much like to have some support for adding a onthology for a data analysis and for ML models should we just add what we believe is a good onthology or would you like to discuss first?

I guess that it might be a good idea to base it on EMMO in order to make it easier to use it together with BattINFO.
