UX: Inventory. Hierarchical result list - with more data

Purpose: For the Inventory app, library staff want to see instance > holdings > item data as the out put of a given search wether the search is in the Instance, Holdings, or Item segment. The new hierarchical display will be the default display which accommodate the need for resource access, resource management, and metadata management daily work task.

The simple MCL display which only displays data from the instance record might be deprecated, or kept as a view, some catalogers might use, in some cases. TBD with the working group

Besides refinement of Filip's redesign, then we need to add more detailed information into the display, e.g.

1. Instance HRID, Holdings HRID, Item HRID
2. Instance resource type
3. Instance format
4. Instance edition
5. Instance publication date (=year)
6. Item call number

Search for an instance record:

Search for a holdings record

Search for an item record

A couple of outstanding UX/UI issues, which we'd need to find a solution for:

1. sorting of the results in the result list, e.g. by Index title, the publication date, etc.
2. the functionality of the navigation bar, in the top of the third pane, and what data to display

Holdings	Item
