THcHodoscope.cxx
    1. Remove from the use of "temp_planes" for SHMS which
         used only 3 planes for beta and determination of start time.

    2. With change of Integral ADC to pC, change TMath::Sqrt(TMath::Max(20.0,adc_pos))
      to Math::Sqrt(TMath::Max(20.0*.020,adc_pos)) to convert 20 channels to pC

    3. Set fGoodFlags[itrack][ip][iphit].onTrack = kTRUE; when fTOFPInfo[ih].onTrack
       Was always FALSE before.

    4. Modify FineProcess
       a. Add calculation of the track X and Y track position at each plane.
       b. Calculate the difference between the track position and position
          measured by hodoscope center. If multiple paddles hit then take
          average of the paddles.

    THcScintillatorPlane.h and cxx

    1. add variables fHitDistance,fTrackXPosition and fTrackYPosition
    2. add methods GetHitDistance(),GetTrackXPosition(),GetTrackYPosition()
    3. add methods SetHitDistance,SetTrackXPosition,SetTrackYPosition
    4. add variables to tree DiffDisTrack,TrackXPos and TrackYPos
    5. set GoodPosAdcPulseTime to frPosAdcPulseTime
    6. set fGoodNegAdcPulseTime to frNegAdcPulseTime
    7. in HodoHit set PosADCtime and NegADCtime to PulseTime
