Remove print statement?

[ehenneken]

Just raising this so we won't forget. Is the following print statement in run.py a debug left-over?

def queue_references(references: list, source_filename: str, source_bibcode: str, parsername: str) -> None:
    """
    queues references for processing by preparing a task and sending it to the queue

    :param references: a list of reference objects to be queued for processing
    :param source_filename: the name of the source file from which references are being queued
    :param source_bibcode: the bibcode associated with the source of the references
    :param parsername: the name of the parser used to extract the references
    :return: None
    """
    resolver_service_url = config['REFERENCE_PIPELINE_SERVICE_URL'] + app.get_reference_service_endpoint(parsername)
    for reference in references:
        reference_task = {'reference': reference,
                          'source_bibcode': source_bibcode,
                          'source_filename': source_filename,
                          'resolver_service_url': resolver_service_url}
        # tasks.task_process_reference.delay(reference_task)
        print('---here')
        tasks.task_process_reference(reference_task)
