ms-keyrun: All information for keyrun review

#' The survey biomass indices for the focal species within the mskeyrun project 
#'
#' Survey data comes from Northeast Fisheries Science Center's Bottom Trawl
#' Survey. Indices are calculated using the \code{Survdat} R package.  This data 
#' set covers the entire bottom trawl survey from 1963 to 2019.
#' All calibration factors have been applied for the change from Albatross IV to
#' Bigelow.  Data from the Bigelow era (2009 - 2019) that are not converted are 
#' in a separate data set (\code{surveyIndexHB}).  This data only covers the focal
#' species of the MS Keyrun Project.  For an expanded data set see 
#' \code{surveyIndexAll}.
