#' Generic function that returns log marginal likelihood from bridge objects. For objects of class \code{"bridge_list"}, which contains multiple log marginal likelihoods, \code{fun} is performed on the vector and its result returned.
#' @title Log Marginal Likelihoods from Bridge Objects
#' @param x Object of class \code{"bridge"} or \code{"bridge_list"} as returned from \code{\link{bridge_sampler}}.
#' @param fun Function which returns a scalar value and is applied to the \code{logml} vector of \code{"bridge_list"} objects. Default is \code{\link{median}}.
#' @param ... Further arguments passed to \code{fun}.
#' @return scalar numeric
