introduce script that generates widget hirachy

this scripts generates a .svg with a hirachy like:
https://phab.enlightenment.org/file/data/jtiilbekufvfa77taf5y/PHID-FILE-5iwtamur4qxtktrcwh77/widget_hirachy.png

blue means something is stable, red means, something is beta.

This script requires ete3 to be installed. You can install it via with
pip with: `pip install ete3`
