For most uses of the <A HREF="../TS/TS.html#TS">TS</A> solvers the user need not explicitly call
<A HREF="../TS/TSSetStepNumber.html#TSSetStepNumber">TSSetStepNumber</A>(), as the step counter is appropriately updated in
<A HREF="../TS/TSSolve.html#TSSolve">TSSolve</A>()/<A HREF="../TS/TSStep.html#TSStep">TSStep</A>()/<A HREF="../TS/TSRollBack.html#TSRollBack">TSRollBack</A>(). Power users may call this routine to
reinitialize timestepping by setting the step counter to zero (and time
to the initial time) to solve a similar problem with different initial
conditions or parameters. Other possible use case is to continue
timestepping from a previously interrupted run in such a way that <A HREF="../TS/TS.html#TS">TS</A>
monitors will be called with a initial nonzero step counter.
