# Snow crab --- Areal unit modelling Hurdle / Delta model
# combination of three models via posterior simulation
# 1. Poisson on positive valued numbers offset by swept are
# 2. Meansize in space and time
# 3 Presence-absence
# the convolution of all three after simulation is called a Hurdle or Delta model

# TODO::: move plotting calls to self-contained functions:
