Returns a :class:`WhatIf` object corresponding to the What If article of
            index passed to the function. If the index is less than zero or
            greater than the maximum number of articles published thus far,
            None is returned instead.

            Like all the routines for handling What If articles, :func:`getWhatIfArchive`
            is called first in order to establish a list of all previously published
            What Ifs.

            Arguments:

                    number: an integer or string that represents a number, this is the index of article to retrieve.

            Returns the resulting :class:`WhatIf` object.
