/*
如果这个节点是叶子节点
如果是空文件夹 --文件夹（ariticleID为空且isLeaf属性为True），为空文件夹 ===> 可删除
如果是知识 --不能删除知识 （此时 ariticleID属性不为NULL 且 idLeaf属性为 True即是）
如果这个节点不是叶子节点（即非空文件夹，里面可能有知识或者 为空不为空的 文件夹）（ariticleID为空且isLeaf属性为false）====> 不能删除
PS:但是这里不显示知识，所以只可能有 叶子节点文件夹 和 非叶子节点文件夹。
* 叶子节点文件夹内部一定没有知识，可以直接删除 ===>有知识的情况 以后版本考虑
* 非叶子节点文件夹内容一定有文件夹或知识，不能删除。
* 逻辑较简单。
* 只是只能从叶子节点删起
* PS：如果一个父节点其下的所有子节点都被删除，则该父节点的IsLeaf属性变为True
