Arguments

MPRecs	A named list of MP recommendations. The names are the same as slotNames('Rec'), except for Misc. Each element in the list is a matrix. With the exception of Spatial, all elements in list have nrow=1 and ncol=nsim. Spatial has nrow=nareas. Matrices can be empty matrix, populated with all NAs (both mean no change in management with respect to this element (e.g. Effort)), or populated with a recommendation. MPs must either return a recommendation or no recommendation for every simulation for a particular slot (i.e. cannot have some NA and some values).
y	The projection year
nyears	The number of historical years
proyears	The number of projection years
nsim	The number of simulations
Biomass_P	An array with dimensions nsim, maxage, proyears, and nareas with total biomass in the projection years
VBiomass_P	An array with dimensions nsim, maxage, proyears, and nareas with vulnerable biomass in the projection years
LastTAE	A vector of length nsim with the most recent TAE
LastSpatial	A matrix of nrow=nareas and ncol=nsim with the most recent spatial management arrangements
LastAllocat	A vector of length nsim with the most recent allocation
LastTAC	A vector of length nsim with the most recent TAC
TACused	A vector of length nsim with the most recent TAC
maxF	A numeric value with maximum allowed F. From OM@maxF
LR5_P	A matrix with nyears+proyears rows and nsim columns with the first length at 5 percent retention.
LFR_P	A matrix with nyears+proyears rows and nsim columns with the first length at full retention.
Rmaxlen_P	A matrix with nyears+proyears rows and nsim columns with the retention at maximum length.
retL_P	An array with dimensions nsim, nCALbins and nyears+proyears with retention at length
retA_P	An array with dimensions nsim, maxage and nyears+proyears with retention at age
retA_P_real	An array with dimensions nsim, maxage and nyears+proyears with realized retention at age. May not asymptote at one
retA_P_real_2	An array with dimensions nsim, maxage and nyears+proyears retA_P_real standardized to max 1
L5_P	A matrix with nyears+proyears rows and nsim columns with the first length at 5 percent selectivity
LFS_P	A matrix with nyears+proyears rows and nsim columns with the first length at full selectivity
Vmaxlen_P	A matrix with nyears+proyears rows and nsim columns with the selectivity at maximum length.
SLarray_P	An array with dimensions nsim, nCALbins and nyears+proyears with selectivity at length
V_P	An array with dimensions nsim, maxage and nyears+proyears with selectivity at age
V_P_real	An array with dimensions nsim, maxage and nyears+proyears with realized selectivity at age. May not asymptote at one
V_P_real_2	An array with dimensions nsim, maxage and nyears+proyears. V_P_real standardized to max 1
Fdisc_P	vector of length nsim with discard mortality. From OM@Fdisc but can be updated by MP (Rec@Fdisc)
DR_P	A matrix with nyears+proyears rows and nsim columns with the fraction discarded.
FM_P	An array with dimensions nsim, maxage, proyears, and nareas with total fishing mortality
FM_Pret	An array with dimensions nsim, maxage, proyears, and nareas with fishing mortality of the retained fish
Z_P	An array with dimensions nsim, maxage, proyears, and nareas with total mortality
CB_P	An array with dimensions nsim, maxage, proyears, and nareas with total catch
CB_Pret	An array with dimensions nsim, maxage, proyears, and nareas with retained catch
Effort_pot	A numeric vector of potential effort
StockPars	A list of stock parameters
FleetPars	A list of fleet parameters
ImpPars	A list of implementation error parameters
checks	Logical. Run internal checks? Currently not used.
control	List of control parameters used internally.

Value
