Trait Objective 

pub trait Objective<Something> {
    // Required method
    fn score(&self, something: &Something) -> f64;
}

Objective function. The genetic algorithms try to minimize this function. Possible functions include “length of program” (the algorithm tries to reduce this, so it will find the shortest program), and “average runtime in machine cycles” (the algorithm tries to reduce this, so it will find faster programs).

Required Methods

fn score(&self, something: &Something) -> f64

Evaluates the objective function
