+/**
+ * Based on the discussion here: http://community.smartthings.com/t/linking-presence-sensors-in-pairs-for-seniors/4915
+ *
+ * Get an alert if one presence sensor leaves without the other one. The alert could be turning on a light, or sending
+ * a push/text message. The original idea was to monitor aging parents where one parent shouldn't be leaving the house
+ * without the other one. Could also work with parents and children, making sure a child doesn't leave without a parent.
+ *
+ * It works by subscribing to "not present" events for the "dependant" presence sensor. If the "main" sensor hasn't also
+ * recently left (in the past minute), then send the alert.
