Title: Explain the purpose in the REAdME

When I pointed some friends to this repo, without preliminatory explanation,
it wasn't completely clear why we developped it.
Hence, I try to explain it in our README, because I'm afraid other people
migh also easily miss the point.
(Said differently: it's clear for us because we now our needs, but it's not
such a common situation)

This PR is just a suggestion.
