Detailed Description

BodyNode class represents a single node of the skeleton.

BodyNode is a basic element of the skeleton. BodyNodes are hierarchically connected and have a set of core functions for calculating derivatives.

BodyNode inherits Frame, and a parent Frame of a BodyNode is the parent BodyNode of the BodyNode.
