Python wrapper "predict_all" in CvSVM class does not appear in the documentation

The OpenCV source code defines a wrapper function for predict( cv::InputArray samples, cv::OutputArray results ) named as "predict_all". However, this function does not appear in the documentation: http://docs.opencv.org/2.4.4-beta/modules/ml/doc/support_vector_machines.html?highlight=svm#cvsvm-predict

I copied the pydocstring and added it to modules/ml/doc/support_vector_machines.rst
