+A RZipFileMemberReaderStream represents a input stream for compressed files in the archive.

+CZipFile will call its member function GetInputStreamL() by passing a pointer to 
+RZipFileMemberReaderStream and the function will return the input stream for the file
+Note: This class is actually a C class as it derives from CBase
