function n = Nitrogen()
% NITROGEN - Return an object representing nitrogen.
%
%   The object returned by this method implements an accurate equation of
%   state for nitrogen that can be used in the liquid, vapor, saturated
%   liquid/vapor, and supercritical regions of the phase diagram.  The
%   equation of state is taken from W. C. Reynolds, "Thermodynamic
%   Properties in SI."
