Feature request: template new nb

[dsm-72]

When I create a new nbdev notebook I almost always have the same structure

# name
> name of notebook of file ##_name.ipynb

---new-cell---

#| default_export name

---new-cell---

#| hide 
from nbdev.showdoc import *

---new-cell---
...
---new-cell---

#| hide
import nbdev; nbdev.nbdev_export()

is there a way to use nbdev to automatically scaffold this in the nbs directory?
