ImportError: cannot import name 'Literal' from 'typing'

I get the following error trying to import draftsman. This is on Mac OS using Python 3.7. Draftsman version 0.9.6

ImportError: cannot import name 'Literal' from 'typing' (/usr/local/Cellar/python/3.7.0/Frameworks/Python.framework/Versions/3.7/lib/python3.7/typing.py)

I can work around this with this but I'm not sure that's a completely compatible fix. Most fixes on the web put something similar into the library itself.

from typing_extensions import Literal
import typing
typing.Literal = Literal
from draftsman import utils
from draftsman.blueprintable import get_blueprintable_from_string

I forgot to put typing_extensions in setup.py; this only affects versions of Python prior to 3.8. Theoretically all you should have to do is run pip install typing_extensions in your environment and it should fix itself. The updated setup.py will be in version 0.9.7.

It looks like splitter.py needs an edit to handle finding Literal either in typing or typing_extensions.

Stack Overflow suggests:

try:
    from typing import Literal
except ImportError:
    from typing_extensions import Literal

Should be fixed as of 1.0.0.
