Analytical records; bound with - part 1: wrap up work on instance to instance linking

Goal/Problem: Instance-instance linking (with "parent" and "child" links between records) allows us to represent whole-part relationships between bibliographic entities and their descriptions.

Need to link multiple instance records to a single holdings record (and the reverse, multiple holdings to a single instance record). Need to identify which elements will be displayed in instance detail record for circulation.

Cataloguing format of
1) Analytical records (= analyzed separate bibliographic records for a work published as a collection) and
2) bound with records (= bound-with monographs are instances of two or more independent works)

Use cases: If one title in a bound-with is checked-out; all other titles bound-with need to be shown as checked out.
As a user I need to see accurate availability at the title level
As circulation staff I need to be able to see what materials are checked out and to what user
Cataloging staff need to see which titles are bound together; if looking at one title, need to know which other titles are bound with it

Analytic record needs to reflect circulation status of analyzed title

Data elements needed? [feedback needed from RA]
