This function is used to train the model using gradient boosting to get a cascade of regressors which can then be used to predict shape.

Parameters
imagesA vector of type cv::Mat which stores the images which are used in training samples.
landmarksA vector of vectors of type cv::Point2f which stores the landmarks detected in a particular image.
scaleA size of type cv::Size to which all images and landmarks have to be scaled to.
configfileA variable of type std::string which stores the name of the file storing parameters for training the model.
modelFilenameA variable of type std::string which stores the name of the trained model file that has to be saved.
Returns
A boolean value. The function returns true if the model is trained properly or false if it is not trained.
