##' @description A CountSet contains information about points located
##' on \code{\link{Outline}}s. Each CountSet contains a list of
##' matrices, each of which has columns labelled \code{X} and
##' \code{Y} describing the cartesian coordinates (in the unscaled
##' coordinate frame) of the centres of boxes in the Outline, and a
##' column \code{C} representing the counts in those boxes.
