Correct hit times for signal propagation along wire for hits in space points.
Don't do hit position along wire time correction more than once.
In the ENGINE, this can happen if a hit belongs to more than one space point.
1) Add TClone arrays to store the raw scint TDC and ADC paddle and values
The arrays are  frPosTDCHits, frNegTDCHits,frPosADCHits and frNegADCHits
There are filled in THcScintillatorPlane:ProcessHits
2) Also modified THcScintillatorPlane::ProcessHits explicitly set variable
padnum=hit->fCounter and index=padnum-1 so the the TClone arrays for
scintillator variable set padnum=1,16 while the index=0-15
Want pdnum=1-16 because it is used in a hitogram fo counts versus
paddle number
3) Because of change to filling PaddleNumber in ProcessHits had
to modify THcScintillatorPlane::PulseHeightCorrection so the
index variable "j" is set to etPaddleNumber()-1 .
Fix a few things in FindHardSpacePoints().
