quick random title number generated that conforms to BRL3.  Is not necessarily unique yet (BRL2)
Created a title_number datbase with a title_numbers table.  Will be used to store any created title numbers.
Uses the title_numbers table to check what the last title was, create the next one, and save.  Gives sequential title numbers with the prefix of TEST
