// In this example, we present a system that places measurement vectors into

// all the components of the classifier system and the data flow. This system
// differs with the previous k-means clustering algorithms in several
// ways. The biggest difference is that this classifier uses the
// \subdoxygen{Statistics}{GaussianDensityFunction}s as memberhip functions
// instead of the \subdoxygen{Statistics}{EuclideanDistance}. Since the
// membership function is different, the membership function requires a
// different set of parameters, mean vectors and covariance matrices. We
// choose the \subdoxygen{Statistics}{MeanCalculator} (sample mean) and the
// \subdoxygen{Statistics}{CovarianceCalculator} (sample covariance) for the
// estimation algorithms of the two parameters. If we want more robust
// estimation algorithm, we can replace these estimation algorithms with more
// alternatives without changing other components in the classifier system.
//
// It is a bad idea to use the same sample for test and training
// (parameter estimation) of the parameters. However, for simplicity, in
// this example, we use a sample for test and training.
