Simple Warping Routine

Rerforms simple 2-D warping based on a set of reference points

The function is a very simple Thin-Plane spline warping of the two images. Image [pink] is warped onto image [get]. The warping is defined by a set of reference points [Zp=[Xp Yp]] on the [pink] image and a set of corresponding points on the template image [get]. The warping implemented will translate Zp -> Zg exactly.

The function does not perfom any interpolation as it can be very application specific.
