why TickMeter class only used in the gpu samples

double t = (double)getTickCount(); // code you want to measure the performance t = ((double)getTickCount() - t)/getTickFrequency(); cout << "times passed in seconds: " << t << endl; I am using the above code to measure performans. recently i saw [TickMeter](https://github.com/Itseez/opencv/blob/master/samples/gpu/tick_meter.hpp) class used in the gpu samples. i wonder why that a useful class not available. is there any reason not to merge it to OpenCV core.
