#' Thomas process individual distribution simulation for one species
#'
#' Usually used internally inside \code{\link{sim_thomas_coords}}
#' This function randomly draws points (individuals) around one or several mother points using Rcpp.
#' The function is an efficient re-implementation of the rThomas function from the spatstat package.
#'
#' @name rThomas_rcpp
#'
#' @param n_points The total number of points (individuals).
#' @param n_mother_points Number of mother points (= cluster centres).
#' @param xmother Vector of \code{n_mother_points} x coordinates for the mother points.
#' @param ymother Vector of \code{n_mother_points} y coordinates for the mother points.
#' @param sigma Mean displacement (along each coordinate axes) of a point from
#' its mother point (= cluster centre).
#' @param xmin Left limit, \code{default}=0.
#' @param xmax Right limit, \code{default}=1.
#' @param ymin Bottom limit, \code{default}=0.
#' @param ymax Top limit, \code{default}=1.
#'
#' @return A dataframe with x and y coordinates.
