#' S4 class union data.frame_OR_EList
#'
#' @description Virtual class union containing members of \code{data.frame} and
#'  \code{limma::Elist}, used internally to handle situations when a returned
#'  object has a type that cannot be guessed from the function call.
#'
#' @return fusion of classes \code{data.frame} and \code{EList}, used within
#'  \code{.biotmle} by class \code{bioTMLE} to handle uncertainty in the object
#'  passed to slot "tmleOut".
