./project2.sh 然后输入年和月，查询某年某月的万年历
./project2.sh -y 然后输入年和月，上下波浪形输出全年万年历，不算真正的万年历，属半成品
./project2.sh -m 然后输入年和月，上下波浪形输出某年某-m月到某年某+m月的万年历，仍是半成品
./project2.sh alert 然后输入年和月，完整显示全年的万年历
属完成作品
大体思路
显示某年某月万年历，是用函数oneday算出某月一号星期几number，函数fday算出某月的总天数，讲这两个参数代入函数display显示某月万年历
全年万年历是织布理论的很好体现。一行一个显示函数，先后调用display1，display2等函数，到第5行时再用display5判断要不要继续织下去。
$1 和$2在调用display3时使用了，不然最后的代码可以做成循环。
