function r = IdealGasReactor(contents)
% IDEALGASREACTOR  Create a reactor with an ideal gas.
% r = IdealGasReactor(contents)
% An IdealGasReactor is an instance of class Reactor where the governing
% equations are specialized for the ideal gas equation of state (and do not
% work correctly with other thermodynamic models). Examples:
%
% .. code-block:: matlab
%
%     r1 = IdealGasReactor         % an empty reactor
%     r2 = IdealGasReactor(gas)    % a reactor containing a gas

% :param contents:
%     Cantera :mat:func:`Solution` to be set as the contents of the
%     reactor
% :return:
%     Instance of class :mat:func:`Reactor`
