This node is used internally by some of the flexor operations. It serves several purposes:
1) It calculates the bend vector at a joint given the joint above, the joint below and the joint itself.
2) It calculates a bend angle. The bend angle is based on the type of joint guide specified for jointGuideAxis. If "auto" is chosen then straight = 0 deg and completely bent = 180 deg.
3) It calculates a bend magnitude. If jointGuideAxis is set to "auto", this is a mapping of the bend angle to the range [0, 1]. For all other settings of jointGuideAxis, it maps the bend angle to the range [-1, 1]. Typically this parameter is used as the motor for high-level joint/bone lattice behavior.
4) It serves as a central location for the typical drivers available for flexors --> rotateX/Y/Z, maxXYZ and autoGuide. This means that the flexor node can connect all of its default drivers to the outputs of the guide node.
