org.evolvica.core.mutate.Double.DoubleMutator
org.evolvica.core.mutate.Double.StepMutator
Mutation of an double number with a maximal stepsize.
This operator will add a random double number within the
range from 0 to a given double number.
The given number can be either positive or negative.
The mutated value = value + random( 0, stepSize )
