concatenate2Dtransforms

This script will generate a single 2D transform node (CornerPin) from a group of several transforms in sequence, baking the animation.
It works with Transform2D, CornerPin and Tracker nodes.

The result is a CornerPin node, with an animation on the extra matrix (the Transform2D node unfortunatelly doesn't have one).
It will use your project settings frame range to bake animations.

Usage: 

load the script, select the nodes and run:
transformstoMatrix()

The transform nodes must be conected for it to work. 
Motion Blur needs to be generated with a VectorBlur, the matrix animation doesn't generate motionblur (maybe a nuke BUG)
