Subject: [PATCH] Fix bug introduced in THcHallCSpectrometer::FineProcess
When making changes to support THcPrimaryKine added line
track->SetEnergy
which set the track energy to energy determined from
measurement of spectrometer delta.
But this energy should be the energy measured by the
Shower calorimeter.
Deleted the line in THcHallCSpectrometer since it is not
needed anyway.
