Creates a fleet object, mostly by adding in selectivity at age for each fleet and species

)Arguments
- metiers
a list of metiers
- mpa_response
one of "stay" or "leave" indicating response of vessels that used to fish in MPA to MPA
- fleet_model
which fleet model to use, one of "constant_effort" or "open_access" or constant catch
- responsiveness
how responsive the fleet is to profits when fleet_model = "open_access"
- cost_per_unit_effort
the cost per unit effort
- spatial_allocation
spatial effort allocation strategy ('revenue','rpue','profit','ppue')
- effort_cost_exponent
exponent of costs
- ports
location of fishing ports
- cost_per_distance
cost per unit distance
- cr_ratio
cost to revenue ratio at initial conditions (1 implies OA equilibrium, total profits = 0)
- resolution
spatial resolution of the simulated seascape
- patch_area
the area of each patch (KM^2^)
- base_effort
base effort for the fleet
- fishing_grounds
the location of fishing grounds (TRUE or FALSE)
