* \brief Base class for decision rules that return a class label

* DecisionRule is the base class for decision rules used in
* classification. Subclasses of DecisionRule include
* MaximumDecisionRule, MinimumDecisionRule, and
* MaximumRationDecisionRule, This class has a pure virtual function,
* Evaluate(), which implements the particular decision rule, given a
* set of discriminant scores. Concrete subclasses of
* DecisionRule must implement this method.
