Profile and name the personas (our own classes)

Describe each cluster with medians/modes and give it a business name; this label becomes a new categorical column. Concepts: Segment profiling; personas as new labels Project A: Example personas: 'Young renters with small short loans', 'Established home-owners with large long loans', 'Mid-career multi-credit borrowers', 'Overdrawn applicants with long loans'. (Actual groups depend on your run.) Project B: Optional: 'workday', 'weekend/holiday', 'heat-wave day'.
