	Unparent Hiearchy Nodes 
	In an effort to clean your fbx scene

	This code is looking for specific nodes in your scene
	In my example I have a heirarchy that houses an entire character or weapon
	Character
	-> Rig_Group
	-> Bind_Skeleton (root)
	-> Meshes_Group

	Weapon
	-> Rig_Group
	-> Bind_Skeleton (root)
	-> Meshes_Group

	My intention is to get the Bind Skeleton and Meshes_Group into the scene world depending on animation or skeletal mesh export
	You could additionally find parent nodes to unparent based on a given name or attributes and traverse up from there.
