#' Class 'output_Split': partitioning solution
#'
#' \code{\linkS4class{output_Split}} is an S4 class to represent the partitioning solution of an item pool.
#'
#' @slot output a list containing item/set indices of each partition.
#' @slot feasible for partitioning into sub-pools, \code{TRUE} indicates the complete assignment problem was feasible.
#' @slot solve_time elapsed time in running the solver.
#' @slot set_based whether the item pool is set-based.
#' @slot config the \code{\linkS4class{config_Static}} used in the assembly.
#' @slot constraints the \code{\linkS4class{constraints}} used in the assembly.
#' @slot partition_size_range the partition size range for splitting into sub-pools.
#' @slot partition_type the partition type. Can be a \code{test} or a \code{pool}.
