Namespaces
namespace	libMesh
	The libMesh namespace provides an interface to certain functionality in the library.
namespace	libMesh::MeshTools
	Utility functions for operations on a Mesh object.
namespace	libMesh::MeshTools::Subdivision
	Utility functions for subdivision surface operations on a Mesh.

Functions
void	libMesh::MeshTools::Subdivision::find_one_ring (const Tri3Subdivision *elem, std::vector< const Node * > &nodes)
	Determines the 1-ring of element elem, and writes it to the nodes vector.
void	libMesh::MeshTools::Subdivision::all_subdivision (MeshBase &mesh)
	Turns a triangulated mesh into a subdivision mesh.
void	libMesh::MeshTools::Subdivision::prepare_subdivision_mesh (MeshBase &mesh, bool ghosted=false)
	Prepares the mesh for use with subdivision elements.
void	libMesh::MeshTools::Subdivision::add_boundary_ghosts (MeshBase &mesh)
	Adds a new layer of "ghost" elements along the domain boundaries.
void	libMesh::MeshTools::Subdivision::tag_boundary_ghosts (MeshBase &mesh)
	Flags the outermost element layer along the domain boundaries as "ghost" elements.

Variables
static const unsigned int	libMesh::MeshTools::Subdivision::next [3] = {1,2,0}
	A lookup table for the increment modulo 3 operation, for iterating through the three nodes per element in positive direction.
static const unsigned int	libMesh::MeshTools::Subdivision::prev [3] = {2,0,1}
	A lookup table for the decrement modulo 3 operation, for iterating through the three nodes per element in negative direction.
