/**
 * 使用Hign-Level API来操作Working Copy，由于所有的操作比较贴近SVN命令行、客户端的操作，所以理解起来相对容易一些。
 * 对于Working Copy的不同操作被分类封装到不同的SVN*Client中，SVNClientManager类包含这些SVN*Client，所以通常使用SVNClientManager类可以很方便的管理这些SVN*Client
 * 所以我们在操作Working Copy时有两种选择：1.可以分别实例化各种SVN*Client类。2.实例化一个SVNClientManager类，实际上在首次请求SVNClient类的时候，它就已经实例化了每个SVN*Client类了。
 * 具体结构详见类图
