// This is a collection of silicon strips in blocks of the same digicode.
//
// To loop over all the strips in a given detector element (myDigiCode),
// you would get the first and last index of the strips in the
// TClonesArray with the fIndexFirstHit[myDigiCode] and fIndexLastHit[myDigiCode] 
// arrays and then fish them out of fSiStripList.
//
// To make basic plots interactively, you can draw the puffed data
// members of the TClonesArray objects (TStnSiStrip).  For example, to
// draw the ADC value vs strip number for a given digicode:
//
// STNTUPLE->Draw("fSiStripList.fADC:fSiStripList.fStrip","fSiStripList.fDigiCode==2130","prof")
