RPQuestionStep class

The concrete subclass of RPStep that represents a step in which a single question is presented to the user.

When a Task Widget presents an Question Step object, it instantiates an RPUIQuestionStep object to present the step. The actual visual presentation depends on the answer format (RPAnswerFormat). When you need to present more than one question at the same time, it can be appropriate to use RPFormStep instead of RPQuestionStep.
