## Description
We currently can’t track whether Wikifunctions are embedded in Wikipedias and Wiktionaries. This task adds instrumentation, discussed with Product Analytics, to enable the creation of a high-level adoption dashboard for embedded Wikifunctions.
In the WikifunctionsPFragmentHandler, when we are triggered on a page we should add details of our usage to [[https://www.mediawiki.org/wiki/Manual:Page_props_table|the page properties table]] (below), which will allow maintenance scripts and analytics to track usage.
[Note: page props are ephemeral parse-time data only related to the current revision.]

[ ] We can extract this data to find pages with fragments (in the current revision)
[ ] We set a string prop on from each fragment on the page page with the ZID of the Function called
[ ] We can extract this data to find pages with fragments using a particular Function
