%
%  constructor for the nonlinear_inequality_constraint class.
%
%  [nic]=nonlinear_inequality_constraint(varargin)
%
%  where the required varargin are:
%    descriptor    (char, description, '')
%    lower         (double, lower bound, -Inf)
%    upper         (double, upper bound, 0.)
%  and the optional varargin and defaults are:
%    scale_type    (char, scaling type, 'none')
%    scale         (double, scaling factor, 1.)
%
%  note that zero arguments constructs a default instance; one
%  argument of the class copies the instance; and three or more
%  arguments constructs a new instance from the arguments.
