This class turns an istream into a sequence of FltRecords by reading a sequence of Datagrams and extracting the opcode from each one.
It remembers where it is in the file and what the current record is.

| FltError FltRecordReader::advance | ( | bool | ok_eof = false | ) |
Extracts the next record from the file.
Returns true if there is another record, or false if the end of file has been reached.
