getBoundaryIDs()

std::vector<libMesh::boundary_id_type> MooseMeshUtils::getBoundaryIDs	(	const libMesh::MeshBase &	mesh,
		const std::vector< BoundaryName > &	boundary_name,
		bool	generate_unknown
	)

If the conversion from a name to a number fails, that means that this must be a named boundary. We will look in the complete map for this sideset and create a new name/ID pair if requested.
