strat_data

Generate set details (setdet), length-frequency (lf)
and age-frequency (af) data for stratified analysis

Simulate age-structured populations that vary in space and time and
explore the efficacy of a range of built-in or user-defined sampling
protocols to reproduce the population parameters of the known population.
