Error with mypy when importing #119
Description
If I run mypy on a module that includes the library with import railroad, I get the following error:
mymodule.py:7: error: Skipping analyzing "railroad": module is installed, but missing library stubs or py.typed marker [import-untyped]
mymodule.py:7: note: See https://mypy.readthedocs.io/en/stable/running_mypy.html#missing-imports
I could ignore it, but I'd prefer not to, given that the library already includes type information.
It seems that py.typed is not included in setup.py. Could adding it be enough?
