Detailed description

Python wrapper for Keypoint and DMatch is totally inefficient in which we need to access each object separately in order to extract its attributes (center, radius, trainingIdx and queryIdx), rather than using Numpy arrays.

Is it possible to change that behavior to something similar to connectedComponentsWithStats wrapper of the stats variable? That wrapper is a Numpy array, smoothly used in conjugation with an exported enum, which allows vectorized operations without any need for loops.
