// And finally we get to the feature ranking. Here we call rank_features() with the kcentroid we just made,
// the samples and labels we made above, and the number of features we want it to rank. Note that
// rank_features() operates on dlib::matrix objects so we need to use the vector_to_matrix() function
// to cast the std::vector objects to dlib::matrix. Also note that the vector_to_matrix() doesn't actually
// copy the std::vector, but instead it uses a template expression technique to recast it as a dlib::matrix
// object. (see the dlib::matrix example and documentation for more details on template expressions).
