RecordHeader

A RecordHeader structure precedes every record in the database (including the DBHeader, but not the 4 byte file signature).

------ ------------   -----------   --------
0      Record Type    char          Type of record
                                    See the following table for specific record types.

2...3  Length         unsigned int  Length of record *including* header
                                    A zero byte record would have 6 as the length.  
4...5  Record Number  int           Sequential record index
                                    Each record type uses its own index starting at 0.
