#' @title Do a cascading delete on gtox screening data
#'
#' @description
#' \code{gtoxCascade} deletes the data for the given id(s) starting at
#' the processing level given. The delete will cascade through all subsequent
#' tables.
#'
#' @param lvl Integer of length 1, the first level to delete from
#' @param type Character of length 1, the data type, "sc" or "mc"
#' @param id Integer, the id(s) to delete. See details for more information.
#'
#' @details
#' The data type can be either 'mc' for mutliple concentration data, or 'sc'
#' for single concentration data. Multiple concentration data will be loaded
#' into the level tables, whereas the single concentration will be loaded into
#' the single tables.
#'
#' If lvl is less than 3, id is interpreted as acid(s) and if lvl is greater
#' than or equal to 3, id is interpreted as aeid(s).
#'
#' @keywords internal
#' 
#' @return None
