List of new augmenters

Augmenter Description
Color Transfer(I) Transfers the LAB colors taken from a random item in source images I (keys identify an image).
Object Insertion(I,L,S) Inserts a random image from a list of images, scaled down to size S at a random position within location L. The anchor of images is set to the center-bottom.
Polygon(P,V,C) Creates random polygons P with shape defined by V on an image, that alter pixels caught in a polygon. If C is not false, polygons may alter pixels channel-wise.
