Merged requested to merge Sample_id_baseclass into develop
This is a draft for having a Sample ID base class. Discussions about its content have been carried out within the frame of Area A. At the moment, the Reference in children and parents' quantities does not seem to work. Additionally,
results.eln.lab_ids does not seem to be populated, or at least I do not seem to be able to see it in search entries in the gui.
This is a good opportunity also to start discussing a strategy to start writing these base classes. I attach a yaml schema to test it.
