- Genome is a trait that implements mutation, mating, distance measure etc.
        (opens up for more experimentation and extensibility)
- The default Genome implementor is NeuralNetwork which implements said functionality
        pretty much just as before. So NeuralNetwork is the new Genome.
        Some slight changes in how bias works had to be done to be able to mirror the way
        they do it in some paper that introduced or explained CTRNN iirc.
- Thus now we pass around Organisms not Genomes

- And..:
    - Update rand
    - Removed lots of unnecessary f64
    - Remove CtrnnNeuralNetwork (can just use Ctrnn for setting up the
        network)
    - Fix an error in species
