Defines functions toolOrderCells

Documented in toolOrderCells

#' toolOrderCells
#'
#' reorder numbered spatial units (cells, clusters) by number. Function
#' will return the unmodified object, if the given subdimension does not exist
#' or does not contain cell information.
#'
#' @param x magclass object that should be ordered
#' @param dim subdimension which contains the cell information
#' @param na.rm boolean deciding how to deal with non-integer information
#' in cellular column. If FALSE, non-integer values will lead to a return
#' of the unsorted object, if TRUE non-integer cells will be removed from
#' the data set and the rest will get sorted
#'
#' @return ordered data in magclass format
#' @author Kristine Karstens, Jan Philipp Dietrich
