/**
 * @file   ShowerCalibrationGaloreFromPID_test.cc
 * @brief  Tests ShowerCalibrationGaloreFromPID service provider
 * @author Gianluca Petrillo (petrillo@fnal.gov)
 * @date   April 28, 2016
 * @see    ShowerCalibrationGaloreFromPID.h
 *
 * Runs a test that instantiates a ShowerCalibrationGaloreFromPID provider with
 * a known configuration and verifies that the same factor is returned for
 * a nominal reconstructed shower.
 * It also prints on screen a "standard" table of corrections, as printed by
 * ShowerCalibrationTableTest().
