Setup
All controls and many relations are in the control armature, underlying are (at least) a geometry armature and splines and empties for spline IK

Arm Constraints
GEO_upperarm.L/.R :
- CopyLocation -> tip GEO_shoulder.L/.R
- CopyRotation -> upperarm.L/.R
- CopyScale -> GEO_shoulder.L/.R
- CopyRotation -> IK_HLP_upperarm.L/.R driven by IKFK
GEO_lowerarm.L/.R :
- CopyRotation -> lowerarm.L/.R
- CopyRotation -> IK_HLP_lowerarm.L/.R driven by IKFK
GEO_hand.L/.R :
- CopyRotation -> hand.L/.R
- CopyRotation -> IKhand.L/.R driven by IKFK
HLP_cpyupperarm.L/.R :
- CopyRotation -> upperarm.L/.R
Arm Notes
AutoShoulder
shoulder.L/.R doesn't automove but displays at GEO_shoulder.L/.R HLP_upperpivot.L/.R is the child of upperarm.L/.R, but has a IKFK driven copyrot to IK_upperarm.L/.R. HLP_lowerpivot.L/.R is at it's tip (at the elbow) and is the target of HLP_autoshoulder.L/.R, with an Autoshoulder driven Damped Track . GEO_shoulder.L/.R is the child of HLP_autoshoulder.L/.R, and that completes the setup.
