Guided brainstorming to set up a new unit in the brain — a client, a student, a patient, a project, whatever the user wants to track: returns the step-by-step script to follow with the user (what to track and what to call it, a few questions, structure proposal, create_unit, filling). Use it when the user says 'nuovo cliente', 'nuovo progetto', 'nuovo studente', 'start project' or wants to add someone/something to the brain.
