Possibly broken kinematic tree in constrained female/male model

[DerZieger]

Hey,

while testing the constrained body models I found a possible error in the kinematic tree.
While changing the value corresponding to the second hinge of the double hinge for the right middle finger, the first single hinge of the right middle finger is also affected.
It seems that one parameter is missing either for the double hinge or single hinge, I suspect that there's a problem in the kinematic tree that reuses the same parameter for both hinges.
The error doesn't occur in the constrained hand model.
