1) THcDCWire.h
a) added sigma to THcDCWire constructor which fills fSigmaWire
b) added GetSimga method
c) added SetSigma method
2) THcDCHit.h
a) Added GetWireSigma method
3) THcDriftChamberPlane.h
a) Added flag fUsingSigmaPerWire
b) Added array fSigmaWire
4) THcDriftChamberPlane.cxx
a) In ReadDatabase, set fUsingSigmaPerWire=0 by default
with reading of parameter h_using_sigma_per_wire optional
for setting fUsingSigmaPerWire.
b) If fUsingSigmaPerWire=0 then sets all wires in array fSigmaWire to
fSigma ( which is the simga per plane).
c) If fUsingSigmaPerWire=1 then reads in the sigma per wire from
a parameter file.
d) Used new THcDCWire constructor to set the sigma for wire to fSigmaWire[nwire]
e) Also change code so that the tzero offset is set in the THcDCWire constructor
f) In ProcessHits , use wire->GetTOffSet instead of the fTzeroWire array when setting
the time.
5) THcDC.cxx
a) In TrackFit, replace fSigma with hit->GetWireSigma()
