Create a script to capture timings and metrics for each implementation

[Flet]

For each implementation example, capture a series of metrics and spit out a little report. Can be pretty quick/dirty:
- timings for build task (i.e. how long does it take npm run build to finish)
- analyze package.json and count required dev dependencies

Possibly output something that can be directly committed to the repo.. maybe .md?

👍

The script should also test build task after atomic changes, since several build tools shine in atomic rebuilds support.

Want to take a crack at it?
