 * \brief C API: Format a date interval.
 *
 * A UDateIntervalFormat is used to format the range between two UDate values
 * in a locale-sensitive way, using a skeleton that specifies the precision and
 * completeness of the information to show. If the range smaller than the resolution
 * specified by the skeleton, a single date format will be produced. If the range
 * is larger than the format specified by the skeleton, a locale-specific fallback
 * will be used to format the items missing from the skeleton.
 *
 * For example, if the range is 2010-03-04 07:56 - 2010-03-04 19:56 (12 hours)
 * - The skeleton jm will produce
 *   for en_US, "7:56 AM - 7:56 PM"
 *   for en_GB, "7:56 - 19:56"
 * - The skeleton MMMd will produce
 *   for en_US, "Mar 4"
 *   for en_GB, "4 Mar"
 * If the range is 2010-03-04 07:56 - 2010-03-08 16:11 (4 days, 8 hours, 15 minutes)
 * - The skeleton jm will produce
 *   for en_US, "3/4/2010 7:56 AM - 3/8/2010 4:11 PM"
 *   for en_GB, "4/3/2010 7:56 - 8/3/2010 16:11"
 * - The skeleton MMMd will produce
 *   for en_US, "Mar 4-8"
 *   for en_GB, "4-8 Mar"
 * 
 * Note:  the "-" characters in the above sample output will actually be
 * Unicode 2013, EN_DASH, in all but the last example.
 *
 * Note, in ICU 4.4 the standard skeletons for which date interval format data
 * is usually available are as follows; best results will be obtained by using
 * skeletons from this set, or those formed by combining these standard skeletons
 * (note that for these skeletons, the length of digit field such as d, y, or
 * M vs MM is irrelevant (but for non-digit fields such as MMM vs MMMM it is
 * relevant). Note that a skeleton involving h or H generally explicitly requests
 * that time style (12- or 24-hour time respectively). For a skeleton that
 * requests the locale's default time style (h or H), use 'j' instead of h or H.
 *   h, H, hm, Hm,
 *   hv, Hv, hmv, Hmv,
 *   d,
 *   M, MMM, MMMM,
 *   Md, MMMd,
 *   MEd, MMMEd,
 *   y,
 *   yM, yMMM, yMMMM,
 *   yMd, yMMMd,
 *   yMEd, yMMMEd
 *
 * Locales for which ICU 4.4 seems to have a reasonable amount of this data
 * include:
 *   af, am, ar, be, bg, bn, ca, cs, da, de (_AT), el, en (_AU,_CA,_GB,_IE,_IN...),
 *   eo, es (_AR,_CL,_CO,...,_US) et, fa, fi, fo, fr (_BE,_CH,_CA), fur, gsw, he,
 *   hr, hu, hy, is, it (_CH), ja, kk, km, ko, lt, lv, mk, ml, mt, nb, nl )_BE),
