// The \doxygen{MaximumDecisionRule} returns the index of the largest
// discriminant score among the discriminant scores in the vector of
// discriminant scores that is the input argument of the \code{Evaluate()}
// method.
//
// To begin the example, we include the header files for the class and the
// MaximumDecisionRule. We also include the header file for the
// \code{std::vector} class that will be the container for the discriminant
// scores.
