In optimall: Allocate Samples Among Strata

#' Wave Class for Multi-Wave Sampling Organization
#'
#' \pkg{optimall} defines three S4 classes for organizing the
#' multi-wave sampling workflow: \code{Wave}, \code{Phase},
#' and \code{Multiwave}.
#' An object of class \code{Multiwave} holds metadata and a list of objects of
#' class \code{Phase}, which in turn holds metadata and a list of
#' objects of class
#' \code{Wave}. These three object classes are used together to organize the
#' workflow of multi-wave sampling designs.
#'
#' @slot metadata A list containing the metadata for the wave.
#' @slot design a dataframe specifying the design of the wave.
#' Is often the output of \code{allocate_wave}.
#' @slot samples A character vector containing the ids of the units
#' sampled in the wave.
#' @slot sampled_data A dataframe holding the data, with ids,
#' \emph{collected} in this wave of sampling
#' @slot data A dataframe holding the updated full data set with all of
#' the Phase 1 sampling units including the samples collected in this wave.
#' @import methods
#' @export Wave
#' @exportClass Wave
