// THcHodoscope //
// //
// Class for a generic hodoscope consisting of multiple //
// planes with multiple paddles with phototubes on both ends. //
// This differs from Hall A scintillator class in that it is the whole //
// hodoscope array, not just one plane. //
// //
// Date July 8 2014: //
// Zafr Ahmed //
// Beta and chis square are calculated for each of the hodoscope track. //
// Two new variables are added. fBeta and fBetaChisq //
