Self-contained nuke knobChanged callbacks...To be able to add a callback when knobs change on a group or gizmo without having to create init callback scripts on the menu.py and stuff.So it is waaay better to do it like this for copypastas :D

hi, this might be a stupid question, but where does the code below "##alternatively###" line go.
Does the code in a PyScript knob on the node? in the menu.py file? Having a hard time getting the code to run in the appropriate place.
