Zero Transforms with Groups. [Maya Python]

When it comes to rigging, it's important to keep controllers clean while keeping it's orientation. Since freeze transformations destroys the orientation data, this is a little script I wrote to zero out object transforms using groups.

 Install Instructions:  
      1. Copy the mel script (ZeroTransformsWithGroup.py) to your local user/scripts folder:  
        Example path to icons folder:   
        C:\Documents and Settings\*USERNAME*\My Documents\maya\#.#\scripts        
      2. Copy the icon file (ZeroTransformsWithGroup.png) to your user/prefs/icons folder:  
           Example path to icons folder:   
           C:\Documents and Settings\*USERNAME*\My Documents\maya\#.#\prefs\icons        
        3. Then type the below code into a Maya Python tab:                                 
           import AC_ZeroTransformsWithGroup as zero  
           zero.AC_ZeroTransformsWithGroup()  
      4. Create the command on the shelf and so you have a button.   
       You should now have a new shelf button.   
       When you click the button it will create a group above   
       your selection to zero out the transforms.  
 Description:  
     A script that will take your selection and zero out the   
     transforms by putting an empty group above it with matching  
     transforms. This script only works on single selection.
