% PAIRWISE
%
% Construct a dag-svm multi-class support vector classification network.
%
% Examples:
%
%    % default constructor (a 0-class dagsvm network!)
%
%    net1 = dagsvm;
%
%    % copy constructor
%
%    net2 = dagsvm(net1);
%
%    % construct dagsvm multi-class svc from a vector of two-class networks
%
%    net3 = dagsvm(net)

% Description : Constructor for a class providing a framework for constructing
%               multi-class support vector classification networks from a set
%               of two-class networks using the dagsvm rule.  Part of an
%               object-oriented implementation of Vapnik's Support Vector
%               Machine, as described in [1].
