Flip the node handles,
This can be used to tweak the curvature of the node provided,
Instead of providing the node, you need to provide two variants, the branch key and the node index in the nodes list of the branch.

    public static void Node_FlipHandles(SPData sPData, int BranchKey, int NodeIndex)

Example:

//Flip the handles of  the second node of the branch with key 0
