#' Make an educated guess on the separator character
#'
#' This function tries to guess which separator was used in a text delimited file
#'
#' @param file The name of the file which the data are to be read from
#' @param sep_list A vector containing the candidates for being identified as
#' separators. Defaults to \code{c(",", "\t", ";"," ")}
#'
#' @return A character value, corresponding to the guessed separator. One of ","
#' (comma), "\\t" (tab), ";" (semicolon)," " (whitespace)
#' @export

#' @examples
