basics: Add a helper

[HaoZeke]

VIM was giving me trouble since Esc was kicking me out of the terminal.

Thanks @HaoZeke! Neat trick, I actually didn't know about EOF. 😅 I'm a little worried that this might confuse participants though.

Instead, I'm considering to make it even easier, by simply providing a tarball with all the files that can be downloaded via wget. Will do this after finishing up the advanced writing workflows modules.

Actually I agree with you, wget would be best. I don't think any of the participants were writing it out by hand and the copy paste mechanisms are all error prone.

Interestingly, the cat trick works with any user defined END keyword! So:

 $ cat <<STOPME > qe.in
> blah
> blah
STOPME

Works as well ^_^
