var cc  =new CalendarConverter;

    cc.solar2lunar(new Date(2011, 0, 3)); ---> 2010,11,29
    cc.lunar2solar(new Date(2010, 10, 29)); ----> 2011, 1, 3

    农历转公历时，如果那一月是那一年的闰月，则需额外传一个参数，才能得到正确的公历日期
During the conversion from lunar to solar, if that month is a leap month, then you need to pass an additional parameter.

cc.solar2lunar(new Date(2012, 4, 27)); ---> 2012年5月初7, 其中 isLeap为true，表示为闰四月
    cc.lunar2solar(new Date(2012, 3, 7)) ---> 得到错误时间：2012, 4, 27
    cc.lunar2solar(new Date(2012, 3, 7), true) --> 正确: 2012, 5, 27
