Typedefs
using	igl::shapeup_projection_function = std::function< bool(const Eigen::PlainObjectBase< Eigen::MatrixXd > &, const Eigen::PlainObjectBase< Eigen::VectorXi > &, const Eigen::PlainObjectBase< Eigen::MatrixXi > &, Eigen::PlainObjectBase< Eigen::MatrixXd > &)>
	Every function here defines a local projection for ShapeUp, and must have the following structure to qualify:

Functions
bool	igl::shapeup_identity_projection (const Eigen::PlainObjectBase< Eigen::MatrixXd > &P, const Eigen::PlainObjectBase< Eigen::VectorXi > &SC, const Eigen::PlainObjectBase< Eigen::MatrixXi > &S, Eigen::PlainObjectBase< Eigen::MatrixXd > &projP)
	This projection does nothing but render points into projP.
bool	igl::shapeup_regular_face_projection (const Eigen::PlainObjectBase< Eigen::MatrixXd > &P, const Eigen::PlainObjectBase< Eigen::VectorXi > &SC, const Eigen::PlainObjectBase< Eigen::MatrixXi > &S, Eigen::PlainObjectBase< Eigen::MatrixXd > &projP)
	the projection assumes that the sets are vertices of polygons in cyclic order
template<typename DerivedP , typename DerivedSC , typename DerivedS , typename Derivedw >
bool	igl::shapeup_precomputation (const Eigen::PlainObjectBase< DerivedP > &P, const Eigen::PlainObjectBase< DerivedSC > &SC, const Eigen::PlainObjectBase< DerivedS > &S, const Eigen::PlainObjectBase< DerivedS > &E, const Eigen::PlainObjectBase< DerivedSC > &b, const Eigen::PlainObjectBase< Derivedw > &wShape, const Eigen::PlainObjectBase< Derivedw > &wSmooth, ShapeupData &sudata)
	This function precomputation the necessary matrices for the ShapeUp process, and prefactorizes them.
template<typename DerivedP , typename DerivedSC , typename DerivedS >
bool	igl::shapeup_solve (const Eigen::PlainObjectBase< DerivedP > &bc, const std::function< bool(const Eigen::PlainObjectBase< DerivedP > &, const Eigen::PlainObjectBase< DerivedSC > &, const Eigen::PlainObjectBase< DerivedS > &, Eigen::PlainObjectBase< DerivedP > &)> &local_projection, const Eigen::PlainObjectBase< DerivedP > &P0, const ShapeupData &sudata, const bool quietIterations, Eigen::PlainObjectBase< DerivedP > &P)
	This function solve the shapeup project optimization.
