incorporate additional survey data

[afredston]

Right now the model just uses NEUS spring survey data, which is the simplest because the survey has been very consistent, and every haul collected length data. Other datasets to consider incorporating:

• SEUS SEAMAP trawl survey (has length data for some, not all, tows; but has biomass for all)
• Scotian Shelf trawl data (has biomass for all?)
• Southeast Reef Fish Survey (SERFS) - fixed gear

If we choose some summary statistics to use in the ABC fitting that sum across length classes or that just use pres/abs, then I think we could include the other surveys.
