Nio.pth not installed with absolute pkgs_pth #20

I've been working on installing PyNIO from source on Ubuntu 18.04. I'm able to install the package, with the exception of the Nio.pth file. The result is that, when I try to import the package, I get

ImportError: No module named Nio

After some experimentation I found that distutils doesn't respect absolute file paths for data_files in the setup function. I was able to fix this by replacing the absolute path with a relative path:

setup (version      = pynio_version,
       description  = 'Multi-format data I/O package',
       author       = 'David I. Brown',
       author_email = 'dbrown@ucar.edu',
       url          = 'http://www.pyngl.ucar.edu/Nio.shtml',
       long_description = '''
       Enables NetCDF-like access for NetCDF (rw), HDF (rw), HDF-EOS2 (r), HDF-EOS5, GRIB (r), and CCM (r) data files
       ''',
       package_data = { pynio_pkg_name : data_files },
       data_files   = [('.', pynio_pth_file)],
       **configuration().todict())

I tested this out on Ubuntu 18.04 with both python 2 and 3, and both pip and python setup.py install. In each case, only the relative path copied Nio.pth to the correct location.
