%  Parameters:
%
%    Input, integer NEQN, the number of equations.
%
%    Input, integer NEXT, the index of the previous
%    equilibrium, which should be 0 on first call.
%
%    Output, real Y(NEQN), the "next" equilibrium solution, if any.
%
%    Output, integer NEXT, the index of the current equilibrium, 
%    or 0 if there are no more.
