* @author ralmond
*
* This formatter takes two arguments and examines the field text.
* If the field text represents multiple individuals, that is it contains the string "and"
* then the field text is replaced with the first argument, otherwise it is replaced with the second.
* For example:
*
* \format[IfPlural(Eds.,Ed.)]{\editor}
*
* Should expand to 'Eds.' if the document has more than one editor and 'Ed.' if it only has one.
