The AnswerFormat class is the abstract base class for classes that describe the format in which a survey question should be answered. The ResearchStack framework uses QuestionStep to represent questions to ask the user. Each question must have an associated answer format.

To use an answer format, instantiate the appropriate answer format subclass and attach it to a question step or form item. Incorporate the resulting step into a task, and present the task with a ViewTaskActivity.
