This PR introduces the data model and manipulation routines for "traversed links" interpolated from observed journeys and their points_on_links. Most of the work was done first in a separate WIP file that was easily testable, and then transferred to relevant schema files. I could tidy up the commits but I don't find it worth the effort - the WIP commit history will describe the development and thinking process quite realistically, I like that approach better.
