ShowerCalibrationGaloreScale.h

Runs a test that instantiates a ShowerCalibrationGaloreScale 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().

Command line arguments: none.
