Fixed a bug that caused reading binary control networks to fail.

    // Now stream the rest of the input into the google protocol buffer.

    try {

      filePos += headerLength;

      int oldLimit = headerCodedInStream.PushLimit(headerLength);

      CodedInputStream::Limit oldLimit = headerCodedInStream.PushLimit(headerLength);

      if (!p_networkHeader->ParseFromCodedStream(&headerCodedInStream)) {

        IString msg = "Failed to read input control net file [" +

            file.name() + "]";

      // choose 64 MB as a safe amount

      int streamThreshold = 1024 * 1024 * 64;

      int currentStreamSize = 0;

      // For some reason, reading the header causes the input stream to fail so reopen the file

      input.close();

      input.open(file.expanded().toLatin1().data(), ios::in | ios::binary);

      input.seekg(filePos, ios::beg);

      IstreamInputStream *pointInStream = new IstreamInputStream(&input);

      CodedInputStream *pointCodedInStream = new CodedInputStream(pointInStream);

    return pvl;

  }
