The current implementation returns the display text, if present, as the
function value. This is correct, as that's the value displayed, but if you
want to actually implement a link, one needs the URL argument also.
I'd lean towards one of:
* ThreadLocal that the hyperlink function checks (with helpful setter and
clearer on it) to toggle between returning the text or link
* setter on FormulaEvaluator that lets you toggle, then pass that
somehow to the hyperlink function
* subclass of FormulaEvaluator with extra evaluateCell method that
returns the link, plus similar to above way to pass flag to function
