TorchScript explanation in long documentation/FAQ?

[ElliottKasoar]

Most people that I've spoken to about FTorch are unfamiliar with TorchScript, and to me the link in the main README doesn't quite explain what it is, but more what it does and how to use it.

I wonder if a very simple (explain like I'm 5) summary and potentially also slightly more technical details might be useful, perhaps on a similar page to the transposition explanation.

It could be nice to group these sorts of questions into an FAQ subsection.
