Add Playground Page.py
#! python3
# Share sheet extension script for adding new pages to Swift Playgrounds (experimental)
# HOW TO USE:
# 1. Add this script as a shortcut to the Pythonista extension (either from Pythonista's settings or the share sheet extension itself)
# 2. Tap the "Share" button in the Playground app's library.
# 3. Select the playground that you want to add a page to
# 4. Select "Run Pythonista Script" in the share sheet
# 5. Run this script, to select the chapter and page title.
# 6. At the end of the script, an "Open in..." sheet will be shown - select the Swift Playground app there. This will create a copy of the playground in your library, with the new page added to it.
# NOTE: Only tested in Pythonista 3, some minor modifications may be needed to make it work in 2.x.

It works! @omz, does this mean you're working on creating an educational book for Playgrounds, or is this just for kicks?
