/* MS, Nov. 23, 2000
Added the calls to base class I/O routines that print the fitness
Left printing/reading of the size of the bitstring,
for backward compatibility, and as it is a general practice in EO
MS, Feb. 7, 2001
replaced all ...Bin... names with ...Bit... names - for bitstring
as it was ambiguous with bin...ary things
