Entropy
Name
Entropy --  Computes entropy via a MessageProbe.
Description
 Entropy objects read probabilities (via a MessageProbe) from a collection of objects and calculate the entropy of the underlying distribution.
Methods
Phase: Creating
- -  setCollection: aCollection-  The setCollection method sets the collection of objects that will be  probed. 
Phase: Using
- - (double) getEntropy-  The getEntropy method returns the calculated Entropy. The entropy value is read out of the object, not computed everytime it is requested. 
- - (void) update-  The update method polls the collection and updates the entropy. This method should be scheduled prior to collecting the data using getEntropy.
