Creates a duplicate of the specified joint which will remove the twist.
Based on Victor Vinyal's nonroll setup
Duplicates the joint and deletes all children apart from the first child joint ( there must at least a single child joint in the hierarchy )
Creates an RP IKHandle with the pole vector set to zero
Parents the pole vector to the original joint
point constrains the nonRoll to the joint
groups the nonRoll outside the hierarchy
Also creates an 'info' locator which is parented to 'nonRoll' and aim constrained to 'nonRollEnd' using 'joint' as its up vector -
- this is the node from which to read the twist value
