Generate an installable Python package for a pipeline. Includes binary data,

meta and required installation files. A new directory will be created in the
|
|
specified output directory, and the data will be copied over. If
|
|
--create-meta is set and a meta.json already exists in the output directory,

the existing values will be used as the defaults in the command-line prompt.

After packaging, "python setup.py sdist" is run in the package directory,

If additional code files are provided (e.g. Python files containing custom

registered functions like pipeline components), they are copied into the
