<div class="block">Class encapsulating training data.
Please note that the class only specifies the interface of training data, but not implementation.
All the statistical model classes in _ml_ module accepts Ptr&lt;TrainData&gt; as parameter. In other
words, you can create your own class derived from TrainData and pass smart pointer to the instance
of this class into StatModel::train.
