#' Create a synthetic population having several states.

#' Populate a matrix in which columns represent the states of the individuals and rows represent the individuals.
#'
#' @param states A numeric vector with each element representing the number of individuals in a particular state
#' its index corresponds to.
#' @param shuffle A logical value to enable shuffling of the individuals (rows) in the resulting matrix.
#' @return A matrix of 0s, and 1s. The rows representing the individuals and the columns representing the states
#' the individuals are in
