-// class is to scan entries in a zip file and extract them. The code will
-// look like:
-//
-//   ZipReader reader;
-//   reader.Open(zip_file_path);
-//   while (reader.HasMore()) {
-//     reader.OpenCurrentEntryInZip();

-//   }
-//
-// For simplicty, error checking is omitted in the example code above. The
-// production code should check return values from all of these functions.
-//
-// This calls can also be used for random access of contents in a zip file
-// using LocateAndOpenEntry().
