#' Loads an object from compressed binary format produced by gl.save()
#'
#' This is a wrapper for readRDS()
#'
#' The script loads the object from the current workspace and returns the
#'  gl object.
#'
#' @param file Name of the file to receive the binary version of the object
#' [required].
#' @param verbose Verbosity: 0, silent or fatal errors; 1, begin and end; 2,
#' progress log; 3, progress and results summary; 5, full report
#' [default 2 or as specified using gl.set.verbosity].
#' @return The loaded object
