function h = Hydrogen()
% HYDROGEN  Return an object representing hydrogen.
% h = Hydrogen()
% The object returned by this method implements an accurate equation of
% state for hydrogen 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

% Reynolds, W. C. *Thermodynamic Properties in SI: graphs, tables, and
% computational equations for forty substances* Stanford: Stanford
% University, 1979. Print.
