Detailed Description

QuestionsForKey is a class used to define the questions for a key, and also options that allow us to refine the question during tree-building (i.e.

make a question specific to the location in the tree). The Questions class handles aggregating these options for a set of different keys.

     // RefineClusters called with 2 clusters; would get set to that anyway as
     // it's the only possible value for 2 clusters).  User has to add questions.
     // This config won't work as-is, as it has no questions.
