#' Creates a list of arrays for storing the dht results
#'
#' Creates a list of arrays. These are used to store the summary, abundance
#' and density outputs of the \code{dht} routine called from \code{mrds}.
#'
#' @param species.name a list of all the species in the analysis
#' @param species.code.definitions a list with an element for each
#' unidentified code which contains a vector of corresponding identified
#' species codes or NULL if not required
#' @param region.table dataframe of region records - Region.Label and Area
#' @param clusters boolean, TRUE if observations are of cluster, FALSE if
#' observations are of individuals.
#' @param n the number of bootstrap iterations to be completed.
#' @return list of arrays
#' @note Internal function not intended to be called by user.
