sort_the_dataset (sort tag)
This can go directly on @hash, more or less. Currently the method will sort on the entry called :lethality_percentage.
This can be controlled by the argument to the method.
Suggested parameters for that argument are:
:n_infected
:lethality_percentage
:infectivity_percentage
