implements Comparator<CharSequence>

Windows 资源管理器风格字符串比较器

此比较器模拟了 Windows 资源管理器的文件名排序方式，可得到与其相同的排序结果。

假设有一个数组，包含若干个文件名 {"abc2.doc", "abc1.doc", "abc12.doc"}

在 Windows 资源管理器中以名称排序时，得到 {"abc1.doc", "abc2.doc", "abc12.doc" }

调用 Arrays.sort(filenames); 时，得到 {"abc1.doc", "abc12.doc", "abc2.doc" }

调用 Arrays.sort(filenames, new WindowsExplorerStringComparator()); 时，得到 {"abc1.doc", "abc2.doc", "abc12.doc" }，这与在资源管理器中看到的相同
