#' Elasticizer update function: generate UDpipe output from base text
#' @param out Does not need to be defined explicitly! (is already parsed in the elasticizer function)

#' @param ver Short string (preferably a single word/sequence) indicating the version of the updated document (i.e. for a udpipe update this string might be 'udV2')
#' @param file Filename for output (ud_ is automatically prepended)
#' @return A vector of 1's indicating the success of each update call
