''' Setup test based on locally-stored UFOs
Reads from tests/localufos.csv which has format ufopath,type where
- ufopath is the full path to the ufo
- type is either:
  - "copy" to copy the ufo to local/ufotests/source (to protect against future changes to the ufo
  - "insitu" to use the uso from where it is, for ufos unlikely to be changed during a development cycle
It should be run with stable pysilfont code prior to starting development and will create reference copies of the fonts
by normalizing with checkfix=fix
Once setup, "pytest local/ufotests" will again normalize all the fonts listed and compare with the reference fonts
