#' Throw a Condition

#' Throws a condition of class c("error", "rBDAT", "condition").

#' We use this condition as an error dedicated to \pkg{ rBDAT.}

#' @param message_string The message to be thrown.
#' @param system_call The call to be thrown.
#' @param ... Arguments to be passed to
#' \code{\link[base:structure]{base::structure}}.
#' @return The function does never return anything, it stops with a
