Define history tree data object

[initialshl]

From chrome.history.search, we get list of URLs.
We then call chrome.history.getVisits for each URL to get all VisitItems.

Define a data object for our history tree with the required details, possibly like:
url, title, visitId, referringVisitId, transition, visitTime

using the chrome.history api, is it possible to get the relation between the different URLs?

I was thinking that we might have to use the callbacks like in the answer here https://stackoverflow.com/questions/34957319/how-to-listen-for-url-change-with-chrome-extension

Then we build the history tree on our own by tracking what pages the user goes to.
