    # Step 2:
    #   Get data from Trello API
    #       - Time each card has been in the step it's in
    #       - Escalation level
    #       - Who is assigned (as well as their email)

    # Step 3:
    #   For each card, compare to escalation rules to see if it's at the step
    #   and escalation level it should be at. If not, flag it.

    # Step 4:
    #   Generate reports for each person, showing their own cards.
    #   Perhaps a "master report" with every card.

    # Step 5:
    #   Send out the reports via email.
