/**
* Implementation for the Excel function IF
*
* @author Amol S. Deshmukh < amolweb at ya hoo dot com >
* <p>
* Note that Excel is a bit picky about the arguments to this function,
* when serialised into {@link Ptg}s in a HSSF file. While most cases are
* pretty chilled about the R vs V state of {@link RefPtg} arguments,
* for IF special care is needed to avoid Excel showing #VALUE.
* See bug numbers #55324 and #55747 for the full details on this.
* TODO Fix this...
