0019 /** \class ZdcSimpleRecAlgo
0020 
0021    This class reconstructs RecHits from Digis for ZDC  by addition
0022    of selected time samples, pedestal subtraction, and gain application. The
0023    time of the hit is reconstructed using a weighted peak bin calculation
0024    supplemented by precise time lookup table. A consumer of this class also
0025    has the option of correcting the reconstructed time for energy-dependent
0026    time slew associated with the QIE.
0027 
0028    A sencon method based on a based on a event by event substraction is also
0029    implelented. signal = (S4 + S5 - 2*(S1+S2+S3 + S7+S8+S9+S10))*(ft-Gev constant)
0030    where SN is the signal in the nth time slice
