Class FilterDirectoryReader
A FilterDirectoryReader wraps another DirectoryReader, allowing implementations to transform or extend it.
Subclasses should implement DoWrapDirectoryReader(DirectoryReader) to return an instance of the subclass.
If the subclass wants to wrap the DirectoryReader's subreaders, it should also implement a FilterDirectoryReader.SubReaderWrapper subclass, and pass an instance to its base constructor.
