Pipelines Editor: Should write the selected pipeline to a file named .json (user can override). Import should take the provided JSON file and call load pipeline (use JSON.parse on the contents).
Application Editor: Same as the Pipelines Editor.
Form Editor: The selected step should have all parameters forms written to a file named .json. The selected class should have the dots in the class name converted to underscores and then the file named .json. Each file should only contain the custom form template.
