"""
Example command for removing zero rotations from a locator item.
Clears the zero rotation offset while maintaining the pose. Acts on all selected locator items.

Limitation: Only works if the rotation item's location is subsequent to the zero rotation item
            (As by default when using the skeleton tool)
            
            Existing animation curves are removed
            
Simplified example, no argument handling or command helps/configs added.
