#jfm_dupeRigParentConstrain
#Created by: Seth Meshko, 3danimationartist.com

'''
This script opens a gui window that will allow you to select a skeleton then with a button push automatically 
duplicates your skinned rig, renames each joint, removes all shapes, transforms and effectors and 
creates the parent constraints for each joint and establishes a common control to turn the parent 
constraint network on and off with a single attribute on the skin rig root.
NOTE!: This script will fail if there are any objects in your scene that are named the same as any object
in your new rig.  Although this is fairly unlikely it bears mentioning.
ANOTHER NOTE!: If you are using this after having already run jfm_HandSetup.py then you don't want this script
you want jfm_dupeRigPrntConstWithHandSetup
