/**
 * \file
 * \brief C API: URelativeDateTimeFormatter, relative date formatting of unit + numeric offset.
 *
 * Provides simple formatting of relative dates, in two ways
 * <ul>
 *   <li>relative dates with a quantity e.g "in 5 days"</li>
 *   <li>relative dates without a quantity e.g "next Tuesday"</li>
 * </ul>
 * <p>
 * This does not provide compound formatting for multiple units,
 * other than the ability to combine a time string with a relative date,
