Quiver timeline - add sorting

[noornoorie]

Closes #46

@paulpestov Here, I'm parsing the gt ids to get the year since I couldn't find a year property in the metadata. However, as some gt ids (I found at least one) are not guaranteed to have year in them, year sorting doesn't happen properly. What should I do in this case? I think it's better to have a year property in the gt api response?

Also, for sorting by metrics, I'm using the getLatestRuns function to get the runs to sort. However, it seems that for some gt items, api doesn't return data for latest runs. This also breaks the sorting. What should I do in this case? Should I modify the getLatestRuns function to return the last run or should I create a new 'getLastRuns' function?
