OUP_translator.js

Zotero translator for Oxford University Press
OK, so going off of http://ukcatalogue.oup.com/product/9780194422505.do and http://ukcatalogue.oup.com/product/9780198781875.do (couldn't find an example with translator and composer atm), you could do
```
var auts = doc.getElementsByClassName('authors')[0];
var role = 'author';
if(auts.textContent.trim().indexOf('Edited ') == 0) role = 'editor';
auts = auts.getElementsByTagName('b');

for(var i=0; i<auts.length; i++) {
  var name = ZU.trimInternal(auts[i].textContent);
  item.creators.push(ZU.cleanAuthor(name, role, false);
}
```
(again, this may vary depending on how translators/composers are presented, but you get the idea)
