Functions
bool	mfem::SubMeshUtils::ElementHasAttribute (const Element &el, const Array< int > &attributes)
	Given an element el and a list of attributes, determine if that element is in at least one attribute of attributes.
std::tuple< Array< int >, Array< int > >	mfem::SubMeshUtils::AddElementsToMesh (const Mesh &parent, Mesh &mesh, const Array< int > &attributes, bool from_boundary=false)
	Given a Mesh parent and another Mesh mesh using the list of attributes in attributes, this function adds matching elements with those attributes from parent to mesh.
Array< int >	mfem::SubMeshUtils::BuildFaceMap (const Mesh &parent, const Mesh &mesh, const Array< int > &parent_element_ids)
	Given two meshes that have a parent to SubMesh relationship create a face map, using a SubMesh to parent Mesh element id map.
void	mfem::SubMeshUtils::BuildVdofToVdofMap (const FiniteElementSpace &subfes, const FiniteElementSpace &parentfes, const SubMesh::From &from, const Array< int > &parent_element_ids, Array< int > &vdof_to_vdof_map)
	Build the vdof to vdof mapping between two FiniteElementSpace objects.
template<class T , class RT = decltype(std::declval<T>().GetParent())>
RT	mfem::SubMeshUtils::GetRootParent (const T &m)
	Identify the root parent of a given SubMesh.
