*scratch*.el

* Prolog
** Week 36
*** Exercise 1
*** Exercise 2

should become(if I run the function with point on ** Week 36)

* Exercise 1
* Exercise 2

which I would then like to export as markdown, and then add some metadata to it
for the static site generator I am using

The result should preferably look something like this

---
title: Week 36 (this is from the headline I ran it on)
date: current date
---

# Exercise 1
# Exercise 2

I realize that I will probably have to add the metadata with some fancy elisp
but if possible, I would like to use built-in stuff for the above as much as possible.
