/**
 * 農(nóng)歷日歷。

 * 將農(nóng)歷從1901年到2100年之間各年、月的大小以及歷年節(jié)氣保存，然后基于這些數(shù)據(jù)進(jìn)行計(jì)算。

 * 

 * 新增了幾個(gè)用于農(nóng)歷的常量屬性字段，可以使用get()方法獲取日歷對(duì)應(yīng)的值；

 * 農(nóng)歷年、月、日還可以使用set()/add()/roll()方法設(shè)置，其他農(nóng)歷屬性自動(dòng)計(jì)算；

 * 另外，還提供了getChinese(int field)方法用于獲得農(nóng)歷的中文文字（僅適用于農(nóng)歷屬性和星期）。

 * <ul>
 * <li>CHINESE_YEAR - 農(nóng)歷年</li>
 * <li>CHINESE_MONTH - 農(nóng)歷月</li>
 * <li>CHINESE_DATE - 農(nóng)歷日</li>
 * <li>CHINESE_SECTIONAL_TERM - 當(dāng)月的節(jié)氣</li>
 * <li>CHINESE_PRINCIPLE_TERM - 當(dāng)月的中氣</li>
 * <li>CHINESE_HEAVENLY_STEM - 農(nóng)歷年的天干</li>
 * <li>CHINESE_EARTHLY_BRANCH - 農(nóng)歷年的地支</li>
 * <li>CHINESE_ZODIAC - 農(nóng)歷年的屬相</li>
 * <li>CHINESE_TERM_OR_DATE - 如果當(dāng)天存在一個(gè)節(jié)氣則指示節(jié)氣，否則如果當(dāng)天是初一則指示農(nóng)歷月，否則指示農(nóng)歷日</li>
 * </ul>
 * 注意：

 * 由于Calendar類的設(shè)定，公歷月份從0起始。所有方法都遵循了這一約定。

 * 但所有的農(nóng)歷屬性從1起始。即使是在Calendar提供的方法中，農(nóng)歷月也是從1起始的，并以負(fù)數(shù)表示閏月。

 * clear()方法在某些情況下會(huì)導(dǎo)致農(nóng)歷和公歷日期不對(duì)應(yīng)或是不能達(dá)到預(yù)期的重置效果，應(yīng)盡量避免使用。

 * 使用getSimpleDateString()獲得公歷日期字符串時(shí)，公歷月已經(jīng)修正；

 * 使用getSimpleChineseDateString()獲得農(nóng)歷日期字符串時(shí)，農(nóng)歷閏月以*表示。

 * 
 * @version 0.12 2011-9-5 

 *   <blockquote>修復(fù)一個(gè)當(dāng)使用農(nóng)歷正月日期初始化日歷時(shí)陷入死循環(huán)的問(wèn)題。</blockquote>
 * @version 0.11 2009-12-27 

 *   <blockquote>修復(fù)了獲取中文農(nóng)歷時(shí)未計(jì)算農(nóng)歷日期的問(wèn)題；

 *   加入一個(gè)字段CHINESE_TERM_OR_DATE用于模仿臺(tái)歷的顯示方式：如果當(dāng)天有節(jié)氣則指示節(jié)氣，如果是初一指示農(nóng)歷月，
 *   否則指示農(nóng)歷日。</blockquote>
