v0.2.12

• The result of verdict has 3 new fields: scope, breadth and summary. The label and the rule do not change.
• scope is "these families". The test keeps the families as fixed, so the claim is about these families only.
• breadth is { against, of, ties }: the count of the families against the side of the verdict, of all the families and of the ties.
• summary gives the label, the scope and the breadth in one line, for example better on these families, worse on 2 of 6 (1 tie).
