   * A form of {@link Config} that is generated by looking at fields in the constructor arg that are
   * annotated with {@link ConfigValue}. The class hierarchy is walked from closest to Object to the
   * constructor argument's type, null values are ignored, and the order in which fields are read is
   * not stable (meaning duplicate config values may give different values each time).
   *
   * <p>The main use of this class is to allow an object configured using (for example) jcommander to
   * be used directly within the app, without requiring intermediate support classes to transform
   * flags to config values.
