DescriptorMatcherTrain Method

Trains a descriptor matcher (for example, the flann index). In all methods to match, the method train() is run every time before matching.Some descriptor matchers(for example, BruteForceMatcher) have an empty implementation of this method.Other matchers really train their inner structures (for example, FlannBasedMatcher trains flann::Index ).
