The outcome is used before we actually roll over the accumulation variables and other stuff.

So we assume that the state is already updated, but the other data is not yet rolled-over.

I don't want to plot the very first time stamp, where I don't know the cell size yet, so I check _maxCellHThisTimeStep. If we don't know the cell size yet, we haven't done a single grid sweep. In this case, I don't plot anything. The other check isFirstGridSweepOfTimeStep() ensures that I only plot once prior to the first Runge-Kutta step.
