get_name_list -- adapted from getAuthors code taken from [[Module:RexxS]]
arguments:
	nl_type - type of name list to fetch: nl_type = 'author' for authors; 'editor' for editors
	args - pointer to the parameter arguments table from the template call
	qid - value from |qid= parameter; the Q-id of the source (book, etc.) in qid
	wdl - value from the |wdlinks= parameter; a boolean passed to enable links to Wikidata when no article exists

returns nothing; modifies the args table

Takes standard cs1|2 template parameters and passes all to {{citation}}.  If neither of |author= and |author1=
are set, calls get_authors() to try to get an author name-list from wikidata.  The result is passed to 
{{citation}} for rendering.
