		description:
			See also LinearChromosome.h
			BitStringChromosome is a concrete subclass of
			LinearChromosome.h.
			
			After a BitString has been allocated, one should
			either call initRandom() or define the alleles using
			set(). By default, the mutation probabilities for the
			bits is the inverse of the bit string's length.
