% INCORDER
% perm sorts the columns of At greedily, by iteratively picking
%   the 1st unprocessed column with the least number of nonzero
%   subscripts THAT ARE NOT YET COVERED (hence incremental) by
%   the previously processed columns.
% dz has the corresponding incremental sparsity structure, i.e.
%   each column lists only the ADDITIONAL subscripts w.r.t. the
%   previous ones.
