目前版本不稳定，仍在开发中，使用请谨慎！

日期工具库

仿照java8的LocalDate、LocalDateTime、LocalTime，实现了java8中大部分方法、新增了许多实用的方法

内部使用moment

Example

const localDate1 = new LocalDate();
const localDate2 = LocalDate.of();
const localDate3 = LocalDate.of(2021,5,20);
const localDate4 = LocalDate.now();
localDate3.format();

方法：
    getYear(): number;
    getMonth(): number;
    getDate(): number;
    getWeekDay(): number;
    getWeek(): number;
    getTime(): number;
    weekday(num: number): LocalDate;
    getListDay(start: LocalDate, end: LocalDate): LocalDate[];
    format(pattern?: string): string;
    isSameDay(date: LocalDate): boolean;
    isBefore(date: LocalDate): boolean;
    isAfter(date: LocalDate): boolean;
    plusYear(year: number): LocalDate;
    minusYear(year: number): LocalDate;
    plusMonth(month: number): LocalDate;
    minusMonth(month: number): LocalDate;
    plusDay(day: number): LocalDate;
    minusDay(day: number): LocalDate;
    atStartOfDay(): LocalDateTime;
    toLocalDateTime(): LocalDateTime;
    atEndOfDay(): LocalDateTime;
    atStartOfMonth(): LocalDate;
    atEndOfMonth(): LocalDate;
    atStartOfWeek(): LocalDate;
    setDate(day: number): LocalDate;
    setMonth(month: number): LocalDate;
    setYear(year: number): LocalDate;

const localDateTime = new LocalDateTime();
......

const localTime = new LocalTime();
......
