Tracking-Learning-Detection and MedianFlow

This contribution includes the following logical components into
tracking module:

.) Change Rect to Rect2d into headers for Tracker's methods;
This contribution includes the following logical components into
tracking module:

.) Change Rect to Rect2d into headers for Tracker's methods;
.) MedianFlow tracker;
.) extensible benchmark to compare trackers interactively and
	assess them quantitatively;
.) TLD tracker (work-in-progress);

Work was funded by Google Summer of Code 2014 initiative. Mentors:
Gary
Bradski and Vadim Pisarevsky.
