"""
A FontForge plug-in to generate interpolated instances from 2 characters.
Inspired by the Simplepolator FontLab/RoboFont script by Pablo Impallari
found at http://www.impallari.com/projects/overview/simplepolation
to easily apply the Gunnlaugur SE Briem's method
http://66.147.242.192/~operinan/2/2.3.3a/2.3.3.02.tests.htm
Copy to ~/.FontForge/python/ and then find "Simplepolator" in the Tools menu,
