Topcomponent --sighoff
Topcomponent --sighoff
实现一个置于右边框的Topcomponent：
1、可远程同步更新（根据远程的xml文件），修改（增删）该xml文件，查看、刷新等
2、打包工程，记录该打包后的文件的信息，包括：ProjectName,author,date,message，写入远程xml文件
3、不论是上传该文件信息，还是远程查看该信息，都必须先设置author,repositoryPath,localPath.
4、四个按键：打包文件并写入xml文件信息，远程调用查看该xml文件，刷新查看该xml文件，设置author,repositoryPath,localPath.
代码包括：
class Milestone存储打包文件信息：
class MilestoneTableModel extends AbstractTableModel构造显示的table
interface MilestoneProvider
class Browse extends JPanel 选择文件的按钮和文本显示框
class SystemUtil 包含打包函数（还有一些，没太看）
public final class SignOffTopComponent extends TopComponent implements MilestoneProvider
为主要的Topcomponent代码，包含读、写xml文件
