*   using $_SESSION:
    *   the programmer can add keys/session attributes to help
        keep track of where in the application they are at a given
	time

    *   another common pattern:
        IN each state:
	*   what info does this state need to get (and sanitize/validate)
	    FROM a just-submitted form?
            (typically, from $_POST)

        *   what info from a PREVIOUS state does this state need to
	    get from $_SESSION?

        *   what info will a LATER state possibly need that this state
	    should ADD to (or update in) $_SESSION?
