#' 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 localhost Defaults to false. When true, connect to a local Elasticsearch instance on the default port (9200)
#' @param udmodel UDpipe model to use
#' @param es_super Password for write access to ElasticSearch
#' @param cores Number of cores to use for parallel processing, defaults to detectCores() (all cores available)
#' @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')
