/**
 * @file   BoostedAtomicNumber_test.cc
 * @brief  Tests the AtomicNumber service provider (with Boost unit test)
 * @author Gianluca Petrillo (petrillo@fnal.gov)
 * @date   April 14, 2016
 * @see    AtomicNumber.h
 * @ingroup AtomicNumber
 *
 *
 * This test takes a configuration file as first command line argument.
 * The content of the configuration file is expected to include:
 * - a `services.AtomicNumberService` section with the configuration of the
 *   provider
 * - a `physics.analyzers.expected` section with the expected values (same
 *   format as the service configuration)
 *
