Subject: [PATCH 1/4] ft: Modify registry to include multiple input mapping
 options. Can use /tmp for storage of input catalogs and arguments, store them
 to /results or defaults to {model_dir}/input. refac: Modified prepare_args to
 handle different template and target args files. tests: extended tests for
 multiple args file types.
