#' @title Loads required data for the simulation
#'
#' @description Loads the total population density file of England as a RasterLayer object. The population is
#'              divided over a 100 metre grid.
#'
#' @details Note that the function attempts to load the file in the RAM if possible for faster computation later.
#'
#' @return Creates one RasterLayer object in the Global Environment.

#' @examples

#' @export
