constructor
This constructor is called for a standard letter-envelope iterator instantiation. In this case, set_db_list_nodes has been called and probDescDB can be queried for settings from the method specification. It is not currently used, as there are not yet separate nond_quadrature/nond_sparse_grid method specifications.

convert scalar_order_spec and vector dim_pref_spec to vector aniso_order
Converts a scalar order specification and a vector anisotropic dimension preference into an anisotropic order vector. It is used for initialization and does not enforce a reference lower bound (see also NonDQuadrature::update_anisotropic_order()).
