SWAP of landmarks about face-alignment-at-3000fps HOT 2 CLOSED

Hi, what the code do in data_augmentation function is just flip the face. When your flip a face, all landmarks will change their position to (1-x, y), and symmetrical landmarks also will change their meaning. For example, left eye center is turned to be right eye center. The data has all landmarks in an order, 5 landmarks for example, left eye center, right eye center, nose, left mouth corner, right mouth corner, then, we need to swap the symmetrical landmarks after changing their position.

Hope you get the idea of why we need SWAP. :-)
