 * \brief Alcohol3 Click example
 * 
 * # Description
 * Code of this sensor reacts to the presence of deoxidizing and reducing gases,
 * such as ethanol (also known as alcohol).
 *
 * The demo application is composed of two sections :
 * 
 * ## Application Init 
 * Application Init performs Logger and Click initialization.
 * 
 * ## Application Task  
 * Reads percentage of alcohol in the blood (BAC) 
 * and this data logs to USBUART every 1 sec.
