elasticizer: updated dump handling to create a dump for every batch, instead of one big file at the end
out_parser: streamlined code
query_gen_actors: only include relevant fields
ud_update: changed function parameters to work with elasticizer dump function
dfm_gen: remove multicore, update merger() code
elasticizer: changed filenaming scheme for dump option
merger: Fixed bug where an NA lemma would cause the entire document to become NA. Now the NA lemmas are filtered out before merging
ud_update: removed parallel processing, changed script to save bulk updates in .Rds files instead of sending them straight away
modelizer: Minor update to feature keyness, using absolute values now to determine the most informative features for a class (so features that are either strongly postively or negatively related to the class)
bulk_writer: Added the 'ver' parameter to include a short version string with each update. Mostly to deal with updates that do not complete successfully on all data
