NJW (and other German law journals)

This style is based on the "Juristische Zitierweise (Stüber)" style by Oliver Wolf and Philipp Zumstein
    (https://www.zotero.org/styles/juristische-zitierweise), but the citation is adapted for the style of
    German law journals, such as NJW (Neue Juristische Wochenschrift), MMR (Multimedia und Recht) etc., as follows:
    - Citations are in-text. In German legal journals sometimes citations are used in footnotes, sometimes in-text,
      although the citation itself does not differ. With "in-text", you can choose for yourself and create the
      footnotes yourself using your word-processor if necessary.
    - Citations do not end with ".". The "." is obsolete for in-text citations. Furthermore, citations in German law
      journals are often accompanied by supplemental text and explanations.
    - Commentaries and handbooks should use publication type "entry-encyclopedia". See details below.
    - note that some law journals use slightly different citation
this needs to be author-date if the style is in-text: we can discuss being more flexible about that, but that's the current requirement for the Travis test.
