- A config file to specify path to the directory with library files can
be used, (put in `~/.config` or `~`). `~` derived by
`os.path.expanduser('~')`.

`dwdat2py.wrappersimport()`, taking care of init, opening, closing
data file and de_init.
- Written for Python 3.
- DWDataReaderHeader.py just copied as is to the repo. (instead of
renaming to dwheader.py and tweaking it).
- Tests rewritten and more tests added.
- Change to Apache 2.0 license.
- DWDataReaderv.doc.txt is produced with
``$ antiword DWDataReaderv.doc > DWDataReaderv.doc.txt``
