/*! -Class:   CellCorrectionAlg
  - Author:   Michel Lefebvre
  - Date:     13/8/2003
  - Description: CellCorrectionAlg is a systemAlg that computes cell signal correction factors
                 - for HV effects
                 - for sampling fraction effects
                 - for global timing effects
                 Corrected signal is obtained by multiplying the signal by the correction factors
