[Contrib: Evaluation System] EVALSYS-916 and EVALSYS-1055

[Jim Eng]

Below is part of the text of a daily status message that is sent to everyone involved in monitoring performance of the evaluation tool.  This was from about three weeks ago, at the peak of the Fall semester eval period.  It indicates that emails were sent to 22,000 users in a little less than 90 minutes.  That is using the newer version of Dick's email notification code. I think this means that 22,177 separate emails were sent.  But it's possible that it was more or less than that, depending on how the messages were aggregated.  But I'm guessing this is approximately the same size job Maryland needs to process in a short amount of time.

For a number of reasons, he reimplemented that capability in a different way at a later time with additional features, but that code is in the CTools branch and not available in trunk.  I think the major reason for that later work was because the original did not perform well.  The new version sends the notifications in much less time.
