Ryan Roberts - Wrap Deformer
rr_wrap.py

Description:
    Ryan Robers created a simple function to create a wrap deformer.  
    The wrap deformer needs a little more than the deform command to get working.
    Michael Clavan
    I wanted to have the function also return the deformer to the user.  So, my contributions are pretty minor.
    I converted the wrap deformer into a pynode object type pm.nt.Wrap.
