StEvent - A real example: StAnalysisMaker::Make()
tuple[k++] = ctbsum; // CTB
tuple[k++] = theZdc.adcSum(); // ZDC
// This is just an example on how to use little
// helper functions which makes the code more readable.
tuple[k++] = countPrimaryTracks(*event);
tuple[k++] = countPrimaryPions(*event);
