/****************************************************************************************
* Java日歷程序
* 作者：張亞航
*
* 完成時間：2008-5-22
*
* 程序功能：
* 使用Swing組件編寫界面，能夠正確顯示月歷，并且擁有四個按鈕分別進行顯示控制
*
* 設計思路：
* 本程序總體使用MVC設計模式，其中viewer包中的CalWin程序是主界面顯示程序，
* 主要用于界面的生成和數據的刷新；
*
* Model包中的MyDate類是程序日歷的載體，本程序沒有使用JDK的類庫java.util.Date和
* java.util.Calendar類，而是重新構造了MyDate類，該類只能保存精度到日的時間
*
* Control包中的ComputeDate類主要是用來計算每個月的第一天是星期幾以及每個月的總天數
*
* Viewer類中包含了一個內部類Cell，Cell是界面日期表格中顯示中的基本元素，繼承與JLabel
* ，每個Cell對應一個MyDate對象。
*
* 程序主要流程是根據當前baseDate利用ComputeDate計算當前月份的數據，然后將所有數據
* 通過setCell方法同Cell[]數組關聯起來，初始化所有Cell，然后將數據在界面顯示。
* 每次日期發生改變，都要調用一次setCell方法，將所有界面數據刷新。
*
