We have the PeakDetectorAgent which monitors frequency of events, but what if I want to monitor the change of a value in an event over time? Say I have an agentthat monitors temperature in my house, and I want to know if it increases or decreases more than X degrees in Y hours. Is there a way to do this?

I can't seem to find something, but a RateOfChangeDetector or ThirdDerivativeAgent... something of the like would be useful (yay, my next commit I guess)
