Test and compare performance of DOM vs Tabulator tables

[E3V3A]

It would be very useful to measure exactly what the performance impact is when using Tabulator as compared to using a home-made JS DOM generator, as is often used in MMM's.

If someone find it easy to write DOM in JS, I would be extremely happy for PR into dev repo.
(Personally I hate writing DOM, which is why I started this repo in the first place.)
