Provide steady state file example for Ramsey

The final loop should most probably be

NumberOfEndogenousVariables = M_.endo_nbr;                    % Number of endogenous variables.
ys = zeros(NumberOfEndogenousVariables,1);                    % Initialization of ys (steady state).
for i = M_.ramsey_eq_nbr+1:NumberOfEndogenousVariables        % Loop...
  varname = deblank(M_.endo_names(i-M_.ramsey_eq_nbr,:));     %    Get the name of endogenous variable i.                     
  eval(['ys(' int2str(i) ') = ' varname ';']);                %    Get the steady state value of this variable.
end                                                            % End of the loop.
