     allows us to keep an archive of activities for each session whether or not the Teacher remembers to do this.
     Our approach here is purely to support this demo-ad hoc mode for SMILE Plug, and isn't necessarily what we'd do
     for SMILE Global 2.x.
+
+    Perhaps the most efficient way to move forward with this routine is to only post updates to this data
+    if data changes, so we'd have calculate results tied to changes in the data, and the consumers of this
+    data would access the "cached result".  Worry about optimization later, as I've only introduced bugs with
+    attempts at optimizing the results.
