For details of its use see the tech-doc

Either pulls data from data tables (~15 mins) or reads in from a previous pull
aggregate landings by stat area or EPU (multiple stat areas)
include foreign landings as defined by NAFO
disaggregates skate and hake complexes using survey data
adjusts value of species for inflation
