- Implement 'cl mimic' and 'cl macro', which allows the user to create a whole
  suite of new bundles according to an existing workflow (defined by an old
  input-output pair).
- Moved bundle_info_to_construct_args into LocalBundleClient.
- Fix 'cl add -m ...' since worksheet items had changed.
- Worksheet items display bundle name only ([name]{uuid}) for simplicity.
- Fix bundle SQL query bug when we're not looking inside a worksheet.
- Modified basic_ml.sh example.
