Quill teaches you a topic

The lines the agent sends:

say "Let's learn how vaccines work."
plan@learn "Learn a topic" submit="Teach me"
page "Five minutes, then a quiz" body="Tell me what you want to learn, how long you have and what you know already. I'll make a short lesson, one idea a page, with a quick quiz at the end. What you learn becomes cards you review later, next to World capitals."
choose@time "How much time do you have?" "5 minutes"|"10 minutes"|"20 minutes"
choose@know "What do you know about how vaccines work already?" "Nothing yet"|"The basics"|"Quite a bit"
