Auto-nohup for moliere

It would be nice to have a thin wrapper around `moliere` that detects if the command is "moliere analyse" and runs the command in the background, if possible.

Actually, it can be done directly in Bash using this https://github.com/Feat-FeAR/Type_B/blob/main/selfcaller.sh

And while we're at it, we could create an alias command `moliere analyze` for American spelling :-)
