This module provides functionality for translation between nucleotides and amino acids.

NOTE aaDNAseq is lossy. Might be a good idea to consider something more involved?

TODO we need different functions, depending on if we have a part of a genome in DNA form, or some messenger RNA. It'll probably also be useful to return Either, with Left indicating error like partially translated sequence due to intermediate stop codons, or so.

TODO dnaAAseq and aaDNAseq can be nicely optimized using flatten and friends.
