function setTimeStep(s, stepsize, steps)
% SETTIMESTEP - Specify a sequence of time steps.
%
%    stepsize -      initial step size (s)
%    steps    -      array of number of steps to take before
%                    re-attempting solution of steady-state problem. For
%                    example, steps = [1, 2, 5, 10] would cause one time
%                    step to be taken first the the steady-state
%                    solution attempted. If this failed, two time steps
%                    would be taken, etc.
