12726This class models an iterator for primitive JSON types (boolean, number,
12727string). It's only purpose is to allow the iterator/const_iterator classes
12728to "iterate" over primitive values. Internally, the iterator is modeled by
12729a `difference_type` variable. Value begin_value (`0`) models the begin,
12730end_value (`1`) models past the end.
