1.实现用户类CUser。
用户的存储采用文本形式，将用户数组进行json编码。
<span style="color: #000000;">用户文件格式：
</span>* <span style="color: #0000ff;">array</span><span style="color: #000000;">(
</span>* 'user1' => <span style="color: #0000ff;">array</span><span style="color: #000000;">(

文件夹和文件的权限说明：
* 文件权限
* R读 : 允许用户读取（即下载）文件。该权限不允许用户列出目录内容，执行该操作需要列表权限。
* W写: 允许用户写入（即上传）文件。该权限不允许用户修改现有的文件，执行该操作需要追加权限。
* A追加: 允许用户向现有文件中追加数据。该权限通常用于使用户能够对部分上传的文件进行续传。
* N重命名: 允许用户重命名现有的文件。
* D删除: 允许用户删除文件。
*
* 目录权限
* L列表: 允许用户列出目录中包含的文件。
* C创建: 允许用户在目录中新建子目录。
* N重命名: 允许用户在目录中重命名现有子目录。
* D删除: 允许用户在目录中删除现有子目录。注意： 如果目录包含文件，用户要删除目录还需要具有删除文件权限。
*
* 子目录权限
* I继承: 允许所有子目录继承其父目录具有的相同权限。继承权限适用于大多数情况，但是如果访问必须受限于子文件夹，例如实施强制访问控制（Mandatory Access Control）时，则取消继承并为文件夹逐一授予权限。
