 * Layer study algorithm: runs data preparation and then dumps all the hits
 * into FPGATrackSimBinning, to produce a "layer study" tree.
 *
 * Pulled out of the genscan/inside out pattern recognition block, to facilitate
 * running layer studies with either the first stage or second stage hits (or both).
