void	updateMu(const Eigen::Vector3d & pt, double C, size_t index) Updates the value of mu according to the augmented lagrangian update.
Eigen::Vector3d	lagragianGradient(const Eigen::Vector3d & pt, double C, size_t index) const Computes the lagrangian gradient based on lagrangian inequality equations. NOTE: Not actually lagrangian. We are using quadratic penalty and not lagrangian because it works better.
