`createChoice(value, navigationItem)`

Creates a new choice with a page-navigation option that jumps to a given page-break item.

The page navigation occurs after the respondent completes a page that contains the option, and only if the respondent chose that option. If the respondent chose multiple options with page-navigation instructions on the same page, only the last navigation option has any effect. Page navigation also has no effect on the last page of a form.
