#filter(queries = []) ⇒ Object

todo/check: find a better name for helper?

 find_all_datasets, filter_datatsets - add alias(es???
queries (lik ARGV) e.g. ['at'] or ['eng', 'de'] etc. list of strings

todo/fix - check if used anywhere???
          - check if works with new alt codes too (or needs update)???

use a function for (re)use

note - may add seasons in place!! (if seasons is empty)

todo/check - change source_path to (simply) path - why? why not?
