     * Abstract base class for trainable facemark models
     *
     * To utilize this API in your program, please take a look at the REF: tutorial_table_of_content_facemark
     * ### Description
     *
     * The AAM and LBF facemark models in OpenCV are derived from the abstract base class FacemarkTrain, which
     * provides a unified access to those facemark algorithms in OpenCV.
     *
     * Here is an example on how to declare facemark algorithm:
     * <code>
     * // Using Facemark in your code:
     * Ptr&lt;Facemark&gt; facemark = FacemarkLBF::create();
     * </code>
     *
     *
     * The typical pipeline for facemark detection is listed as follows:
     * <ul>
     *   <li>
     *  (Non-mandatory) Set a user defined face detection using FacemarkTrain::setFaceDetector.
     *   The facemark algorithms are designed to fit the facial points into a face.
     *   Therefore, the face information should be provided to the facemark algorithm.
     *   Some algorithms might provides a default face recognition function.
     *   However, the users might prefer to use their own face detector to obtains the best possible detection result.
     *   </li>
     *   <li>
     *  (Non-mandatory) Training the model for a specific algorithm using FacemarkTrain::training.
     *   In this case, the model should be automatically saved by the algorithm.
     *   If the user already have a trained model, then this part can be omitted.
     *   </li>
     *   <li>
     *  Load the trained model using Facemark::loadModel.
     *   </li>
     *   <li>
     *  Perform the fitting via the Facemark::fit.
     *   </li>
     * </ul>
