# This report gathers the user, lead_id, event_time, campaign_id, pause_sec,
# wait_sec, talk_sec, dispo_sec, and status from the vicidial_agent_log as
# well as the the vendor_lead code from the list, and the status_name from
# either the vicidial_statuses or vicidial_campaign_statuses table and
# puts all that information into a CSV file which gets emailed out.
