		description:
			See also Gene.h
			RealValGene is a concrete subclass of Gene.
			But it can be subclassed in order to override
			mutate(). (The attributes are declared to be
			protected, not private.)
			
			A RealValGene instance codes real-valued alleles.
			They are stored as doubles. Therefore setAllele()
			expects a double and getAllele() returns a double.
