1. schedule.rb defines cron job schedule (run 'whenever --update-crontab' to start, 'whenever -c' to stop)

2. The cronjob(s) run the import rake task: rake 'import_group[DB_URL,TABLE,GROUP_NAME_ID]'

3. The rake task runs the import method (ImportHelper.update_or_create_group_from_db_table with params)

4. The import method does the heavy lifting of connecting to the external DB, grabbing phone numbers, matching/creating recipients, and updating/creating the group.
