– impliedAnswerFormat
Some answer formats are constructed of other answer formats. This method allows
a subclass to return a different answer format for use in defining the UI/UX for
the answer format type. For example, a Boolean answer format is presented in the
same way as a single-choice answer format with the choices Yes and No mapping to
@(YES) and @(NO), respectively, so its impliedAnswerFormat is an
ORKTextChoiceAnswerFormat with those options.
