     This is static template method of Algorithm. It's usage is following (in the case of SVM):
     @code
-     Ptr<SVM> svm = Algorithm::read<SVM>(fn);
+     cv::FileStorage fsRead("example.xml", FileStorage::READ);
+     Ptr<SVM> svm = Algorithm::read<SVM>(fsRead.root());
     @endcode
     In order to make this method work, the derived class must overwrite Algorithm::read(const
     FileNode& fn) and also have static create() method without parameters
