Version support

I like to use use_scm_version={"write_to": "path/to/_version.py"} in setup.py, which will have setup.py install/build/etc write the git-tag derived version to the file system (/path/to/_version.py should also not be version controlled). That means tagged releases get a clean version like 0.1.0 but local checkouts with modifications get e.g. 0.1.0.dev1923+g475d04d2 so it's clear it's non-released code.

@sean-leavey The problem with using setuptools_scm is that it doesn't hold the version in the source itself, so a tarball of the source (like what's available directly through gitlab) can not be used as an official source release tarball, and release tarballs need to be generated and held elsewhere.

If we upload to pypi we could use the that as the official source release link though...

Fair point. The nuclear approach to prevent use of the tarball could be to have something like this in gwinc.__init__.py:

# Set version.
try:
    from ._version import version as __version__
except ImportError:
    # No _version.py file is present, which probably means the user tried to run the source tarball directly.
    raise Exception("Please install pygwinc via an official distribution.")

I think that perhaps

try:
    from ._version import __version__
except ModuleNotFoundError:
    import setuptools_scm
    __version__ = setuptools_scm.get_version()

should go into a version.py which is NOT automatically imported with __init__.py so that it doesn't have to be called every time on devel versions.
