#' Class mortalityTable.mixed - Life table as a mix of two life tables
#'
#' A cohort life table obtained by mixing two life tables with the given weights.
#' Typically, when only gender-specific tables are available, unisex tables
#' are generated by mixing the two gender-specific tables for males and for
#' females with a pre-defined, constant proportion (e.g. 60:30 or 40:60,
#' depending on the portfolio and on the security margins).
#'
#' @slot table1 The first \code{mortalityTable}
#' @slot table2 The second \code{mortalityTable}
#' @slot weight1 The weight of the first mortality table
#' @slot weight2 The weight of the second mortality table
#' @slot loading Additional security loading
