Documented in completeArrLst

#' Complete list of arrays for same dimensions
#'
#' This functions aims to inspect repeating structues of data given as list of arrays and will try to complete 
#' arrays with fewer lines or columns (as this may appear eg with the very last set of high-thourput sceening data 
#' if fewer measures remain in the last set). Thus, the dimensions of the arrays are compared and 
#' cases with fewer (lost) columns (eg fewer experimental replicates) will be adjust/complete  by adding column(s) of NA.
#' Used eg when at reading mircotiterplate data the last set is not complete.
#' @param arrLst (list) list of arrays (typically 1st and 2nd dim for specific genes/objects, 3rd for different measures associated with)
#' @param silent (logical) suppress messages
#' @return list of arrays, now with same dimension of arrays 
#' @param callFrom (character) allows easier tracking of message(s) produced
#' @seealso \code{\link[wrMisc]{organizeAsListOfRepl}}, \code{\link[wrMisc]{extr1chan}}
