Python library for converting between various morphosyntactic tagging schemes (initially just for Ancient Greek)

Not much code yet, just:

• initial documentation of schemes: postag-schemes.md
• links to or extracts from previous code I've written: prior-art.md
• regexes (and test data) for testing against the Robinson scheme, two variants of MorphGNT, and two variants of Morpheus: run test_parse.py

Support also planned:

• Leipzig Glossing Rules (although problematic for languages like Greek that don't really have morphemes)
• Universal Dependencies and universal features and universal parts of speech in particular

but the first priority is just consolidating my existing code.
