Ninjascript programming

[MicroAl]

I refer to the example samplestream writer that has been provided.

If I was to create another indicator based on the above indicator by copying the region variables and the onbar update method, would compiling add the required lines as shown beneath the namespace NinjaTrader.Indicator section and namespace NinjaTrader.MarketAnalyser section?

I ask this because I am learning C# in relation to Ninjascript and especially StreamWriter. I can basically understand what to put in the onbar update
method if I code something myself, but looking at the sample streamwriter example, clearly more programming has been added under the above mentioned sections. Is this always added automatically by the Ninja compilier?
