Script for adding just authors (and if not available then editor)

[marcocamilo]

Hi Alix,

Since I'm not proficient in Java (tried to do this myself but could seem to find out how to express it), I wanted to ask you what would be the appropriate have script for the following requests:

• If author(s) is(are) available, then push author:: [[First Author]], [[Second Author]], etc. (not the editors)
• If author(s) is(are) not available, then push author:: [[An Editor]] (editor)

I'd like to separate connecting authors and editors, since personally I don't use editor information, unless the citation doesn't include an author(s), but relies on the editor(s).

I'll appreciate the help and as always: thank you so much for this extension!
