Let people traverse the graph, save the taken path, enable replay

[DavidBruant]

A generic solution would be to provide tools to let authors perform object graph traversals, save the paths they've taken (in the style of http://vimeo.com/66085662 ) and let them replay the traversals.
You (devtools team) could use this tool and prepopulate with some paths for popular libraries and hook these pre-populated playable paths to the library heuristics.
