Xenharmlib (music theory library) adds support for Just Intonation

i dont know anything about music but i listened to some music in JI last year and I just sat there in my car in a parking lot listening to the same piano for half an hour on a loop, dumfounded; it was like how you feel after your wisdom teeth are removed

Has anyone used Xenharmlib before? I'm curious about it and a huge fan of the feel of JI, but not super experienced with composition myself, and I was wondering what types of things people have done with it.
