 To run a new pipeline execution, use ``submit_pipeline_execution``.  Required parameters are ``code`` (string), ``start_date`` and ``end_date`` (date-like strings, dates, or Pandas timestamps).  Optional parameters are  ``name`` (string), ``params`` (a dict of parameters to pass to your pipeline), and ``asset_identifier_format`` (which can be "symbol", "sid", and "fsym_region_id").  ``submit_pipeline_execution`` returns an id, which you can pass to ``get_pipeline_execution`` to monitor this pipeline's execution status.
