/**
 * A class for formatting names of people.  Takes raw name data for a person and renders it into a string according to
 * the caller's specifications, taking into account how people's names are rendered in the caller's locale.
 *
 * The Length, Usage, and Formality options can be used to get a wide variety of results.  In English, they would
 * produce results along these lines:
