-==========

-Genomes represent the neural network that underlies a creature. They are an array of tuples of the form `[ source, sink, weight ]`, where:
-
- * `source` is an integer in the range `[0, N - num_outputs)`, representing the index of the source neuron
- * `sink` is an integer in the range `[num_inputs, N)`, representing the index of the sink neuron
- * `weight` is a floating-point value in the range `[-4, 4]`, representing the weight of the connection
-
-`num_input` and `num_output` are fixed by the environment (as they are the input senses and output actions of the creature, respectively).
-`N` is not fixed, but is instead determined by the maximum index present in the genome. As long as the maximum index is greater than or
-equal to `num_input + num_output`, the genome is considered valid.
