RstoxBase: Base StoX Functions

#' Base StoX Functions
#'
#' Base StoX functions used for survey estimation.
#'
#' The StoX functions defined in RstoxBase are those for defining resolution (e.g., PSUs and Layers), assignment, NASC data and StationLengthDistribution data, density, abundance and superindividual abundance
