    00024    Added the calls to base class I/O routines that print the fitness
    00025    Left printing/reading of the size of the bitstring,
    00026        for backward compatibility, and as it is a general practice in EO
    00027
    00028    MS, Feb. 7, 2001
    00029    replaced all ...Bin... names with ...Bit... names - for bitstring
    00030    as it was ambiguous with bin...ary things
