Lesson 2.3 - Mismatch between Completed ChartingActor.cs and code in lesson

[Nij4t2]

Referring to issue #108 which has supposedly not been fixed on that ticket, but in fact the 'Completed' code folder shows this line:

if (series.Points == null) return; // means we're shutting down

which is a fix for that problem, I believe.

Anyway, this line of code is not shown on the lesson webpage which you are instructed to cut-and-paste (ChartingActor.cs) from 'Step 7 - Update the ChartingActor'.
