Public Member Functions
	ElementRestriction ()
	default ctor leaves this object uninitialized

	ElementRestriction (const fes_t *fes, mfem::Geometry::Type elem_geom, const std::vector< int > &domain_elements)
	ctor from a list of elements (e.g. from a smith::Domain)

uint64_t	ESize () const
	the size of the "E-vector" associated with this restriction operator

uint64_t	LSize () const
	the size of the "L-vector" associated with this restriction operator

void	GetElementVDofs (int i, std::vector< DoF > &dofs) const
	Get a list of DoFs for element `i` More...

DoF	GetVDof (DoF node, uint64_t component) const
	get the dof information for a given node / component

void	Gather (const mfem::Vector &L_vector, mfem::Vector &E_vector) const
	"L->E" in mfem parlance, each element gathers the values that belong to it, and stores them in the "E-vector"

void	ScatterAdd (const mfem::Vector &E_vector, mfem::Vector &L_vector) const
	"E->L" in mfem parlance, each element scatter-adds its local vector into the appropriate place in the "L-vector"

axom::Array< DoF, 2, smith::detail::host_memory_space >	dof_info
	a 2D array (num_elements-by-nodes_per_elem) holding the dof info extracted from the finite element space

mfem::Ordering::Type	ordering
	whether the underlying dofs are arranged "byNodes" or "byVDim"
