Win32 SDK TreeView 控件的基本用法，节点的编辑，拖动，添加，删除，弹出菜单
TreeView控件老是用的稀里糊涂的，写个测试程序总结一下基本用法
要注意点：
1.控件是发通知给父窗口处理，因此消息中鼠标的坐标不是相对控件的，要从屏幕坐标转换来。
2.通知消息的返回值 要参考文档，0 一般是允许默认处理，非0 则阻止默认处理。
3.通知消息参数用LPARAM传递，不同的控件起始结构是相同的，后面附加结构不同。
4.通知码是在LPARAM指向的结构中，所以在消息映射表的处理和COMMAND不同，并且通知码是UINT，和nID比较要转换为WORD。
测试程序是WIN32 SDK向导生成的C语言框架。树的操作定义成一个类。 简单起见不封装成窗口类，也不涉及消息映射表。
微软网站上TreeView_XXX 宏的说明文档好多错误，应该是返回句柄的都写成了void型，难道是SDK编程没人用，不维护了？
