Remarks
Creates a cluster in the node hierarchy by re-parenting the Selected Bones off a new node in the hierarchy It makes more sense to think that the Selected Bones are all at the same level in the hierarchy however it will re-parent multiple levels at the InsertAtIndex location bone
e.g. if you have a flat chunk hierarchy after performing Voronoi fracturing L0 Root|
| L1 A B C D |
Cluster A & B at insertion point A, results in L0 Root|
| L1 E C D |
| L2 A B |
Node E has no geometry of its own, only a transform by which to control A & B as a single unit Index of the New Node
