/**
 * @brief Attention handler application main()
 *
 * This is the main interface to the hardware diagnostics application. This
 * application can be loaded as a daemon for monitoring the attention
 * gpio or it can be loaded as an application to analyze hardware and
 * diagnose hardware error conditions.
 *
 *     Usage:
 *        --analyze:              Analyze the hardware
 *        --daemon:               Start the attention handler daemon
 *
 * @return 0 = success
