Algorithm::Evolutionary::Op::Base
Mutation operator for a GA: applies gaussian mutation to a number
Creates a new mutation operator with an application rate. Rate defaults to 0.1.
Called create to distinguish from the classwide ctor, new. It just makes simpler to create a Mutation Operator
Applies mutation operator to a "Chromosome", a vector of stuff, really. Can be applied only to victims with the _array instance variable; but it checks before application that both operands are of type Algorithm::Evolutionary::Individual::Vector.
