#' Function to simplify spatial objects using the Douglas-Peuker algorithm. 
#'
#' Holes will appear between the geometries at times. 
#'
#' @param sp Spatial object which is to be simplified.
#' 
#' @param tolerance Tolerance value to be used by the Douglas-Peuker algorithm. 
#' 
#' @param preserve Should the algorithm attempt to preserve the topology? 
#' Default is \code{TRUE}.
