Lattice and Ladder filters

Let's get some terminology ironed out.  Mostly in relation to [2][3].

Structurally, a d-plane formulation can be associated to a
ladder/lattice topology, and their good numeric properties are well
known.  They also have interesting mathematical properties (see linear
prediction and orthogonal functions on the unit circle [10], and
further work in generalized Schur and displacement rank algorithms for
Toeplitz-structured matrix problems.).
