/**
* 身份證工具類
*
* <p>
* 先來了解一下身份證的組成規則： <br/>
* 1．號碼的結構 公民身份號碼是特徵組合碼，由十七位數字本體碼和一位校驗碼組成。排列順序從左至右依次為：六位數字地址碼，八位數字出生日期碼，三位數字順序碼和一位數字校驗碼。<br/>
* 2．地址碼 表示編碼物件常住戶口所在縣（市、旗、區）的行政區劃程式碼，按GB/T2260的規定執行。<br/>
* 3．出生日期碼 表示編碼物件出生的年、月、日，按GB/T7408的規定執行，年、月、日程式碼之間不用分隔符。 <br/>
* 4．順序碼 表示在同一地址碼所標識的區域範圍內，對同年、同月、同日出生的人編定的順序號，順序碼的奇數分配給男性，偶數分配給女性。<br/>
* 5．校驗碼 根據前面十七位數字碼，按照ISO 7064:1983.MOD 11-2校驗碼計算出來的檢驗碼。<br/>
